Technical Field
[0001] This invention relates to the field of health assessment technology, specifically a method for classifying and assessing the health status of high-altitude populations based on a four-dimensional state space. It is particularly suitable for the quantitative identification and graded early warning of non-organic functional decline and sub-health status during high-altitude exposure. Background Technology
[0002] With increased investment in high-altitude development, a large number of people are moving from low-altitude areas to high-altitude regions. The low-oxygen environment of high altitudes not only induces organic diseases such as acute mountain sickness (AMS), but also leads to "non-organic functional decline" symptoms such as memory loss, slowed reaction time, sleep disorders, and anxiety. For people living in high-altitude areas, this "sub-health state," which has not yet met the criteria for a clinical diagnosis but whose physical functions have already significantly declined, is often more insidious and dangerous than overt diseases, easily leading to long-term physical and mental damage. Accurately identifying this transitional state between disease and health is a pressing issue that needs to be addressed in current high-altitude health protection efforts.
[0003] Currently, assessments of health status at high altitudes primarily focus on two areas: "physiological parameter monitoring and alarm" and "equipment regulation." Existing research collects basic physiological indicators such as blood oxygen saturation and blood pressure, comparing them to preset fixed thresholds. This threshold-based early warning method, based on a single physiological dimension, struggles to identify situations where physiological indicators remain within safe limits, but functional decline has already occurred. Another study constructed a portable long-term health monitoring and adaptive oxygen supply system for high-altitude environments. By incorporating environmental parameters, blood oxygen levels, and GPS information, it monitors and dynamically adjusts the equipment's oxygen output parameters. This method, emphasizing equipment control rather than health assessment, fails to quantify and classify an individual's overall health status and lacks in-depth attention to the complexities of human health, particularly the psychological and cognitive aspects.
[0004] While the aforementioned technologies provide a reference for the prevention and acclimatization assessment of altitude sickness, they still have the following limitations in assessing the sub-health status of people living at high altitudes: First, existing technologies require fixed, pre-defined grading boundaries for classification. This static grading method, which measures dynamic changes, cannot accurately define the individual's state in the early stages of functional disorder or when indicators are in a gray area, and it is difficult to fully reflect the complex impact of the high-altitude environment on the human body. Second, they ignore the "masking effect" of physiological compensation on latent cognitive impairment: the human body may restore routine physiological indicators (such as SpO2) to the normal range in the short term through compensation by the respiratory and circulatory systems (such as increased heart rate and increased red blood cell count). However, due to sleep disorders and nerve fatigue caused by persistent hypoxia, cognitive functions (such as memory and complex decision-making ability) may still be impaired. Existing technologies cannot identify such situations where indicators are normal but physical and mental discomfort persists.
[0005] Therefore, there is an urgent need to develop a method for assessing the physical and mental health of plateau populations that integrates multidimensional data such as physiological, psychological, and cognitive factors, especially a new method for accurately classifying and assessing health, sub-health, and disease states.

[0103] Through extensive and in-depth research, the inventors have, for the first time, constructed a method and system for classifying and assessing the health status of a high-altitude population based on multidimensional data encompassing physiological, psychological, cognitive, and sleep health aspects. Specifically, firstly, this invention collects multidimensional data from the high-altitude population and performs preliminary triage based on environmental exposure characteristics within this data, dividing the population into three subgroups. Secondly, using the "CRITIC-EWM" two-layer weighting method, the micro-weights of each indicator are calculated within each subgroup, followed by the spatial macro-weights of the four dimensions of physiological, psychological, cognitive, and sleep health. Based on these weights, the health status boundary is determined, the closeness between individual scores and health status is assessed, and the closeness set is clustered in the backend to dynamically generate a health level classification boundary. This boundary is then used to classify the health status of individual individuals and provide corresponding intervention suggestions. Furthermore, this assessment process possesses adaptive iterative capabilities, automatically triggering recalibration and optimization of the evaluation standard sequence as the accumulated amount of subject data increases. Based on these findings, this invention was completed.

[0111] After obtaining the health status grading model, in a preferred embodiment of practical application, this method may further include differentiated proactive health interventions based on the grading results: Providing differentiated proactive health intervention strategies. If the subject is at risk of pathological disease or experiencing a decline in sub-health function, the dimension with the lowest overall score is identified, and corresponding "proactive medical repair," "psychological adjustment," or "sleep intervention" repair and regulation strategies are provided. If the disadvantage is in a physiological dimension, suggestions are provided to increase the frequency of oxygen inhalation, force rest, or forcefully reduce physical activity load; if the disadvantage is in a psychological or cognitive dimension, suggestions are provided to mindfulness relaxation training or postpone high cognitive load activities; if the disadvantage is in a sleep health dimension, suggestions are provided to improve the ventilation rate of the sleep environment, reduce the carbon dioxide concentration of the sleep environment, increase the light blocking of the sleep environment, control the noise of the sleep environment, or provide nighttime oxygen supplementation.

[0115] Preferably, the cognitive efficacy dimension feature data mentioned in step S1 includes: a score obtained from the Cognitive Failure Questionnaire (CFQ) to quantify the frequency of daily cognitive errors of the subjects.
[0116] Preferably, the sleep health dimension feature data mentioned in step S1 includes: Objective physiological sleep indicators: the proportion of deep sleep, REM sleep, light sleep, number of awakenings at night, total awake time, and time in bed and total sleep time, all collected using wearable devices; Subjective assessment indicators: Based on the Pittsburgh Sleep Quality Index (PSQI) scale, the scores of seven components are: subjective sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep disorders, use of hypnotics, and daytime dysfunction. Circadian rhythm index: The degree of circadian rhythm disorder calculated based on the absolute difference between the midpoint of sleep on weekdays and the midpoint of sleep on rest days.
[0117] Preferably, the baseline characteristics of environmental and individual behavioral exposures mentioned in step S1 include: Natural environmental exposure parameters: based on the elevation difference calculated from the altitude of the place of residence before entering the plateau and the time spent living in the plateau; Daily activity and work-rest load parameters: daily work / study time and monthly frequency of irregular work-rest schedules.
[0118] Preferably, in step (S2), the preprocessing of the multidimensional dataset specifically includes: standardizing the positive and negative data in the multidimensional dataset using the range standardization method to eliminate dimensional differences; and converting the environmental exposure feature data into feature vectors as input features for subsequent clustering.
[0119] Preferably, the adaptive triage in step S3 specifically includes: using the altitude difference, time spent living in high-altitude areas, daily work / study time, and monthly frequency of irregular work and rest as clustering input features obtained in step S1, the K-means++ algorithm is used to divide the population into acute exposure group, chronic cumulative high load group, and conventional steady-state adaptation group. The algorithm initializes the cluster centers by using distance probability weighting to avoid getting trapped in local optima, aiming to eliminate the prior error caused by the subjective identification of the population by human intervention, and to ensure that the subsequent evaluation is carried out in a homogeneous exposure background.

[0122] Furthermore, the adaptive grading described in step S6 is divided into two stages in practical applications: "benchmark extraction" and "individual mapping." In the benchmark extraction stage, grading boundary thresholds are generated using the initial subject group data. and The system stores the scores of subjects in real time. During the individual mapping stage, the system directly compares the scores of subjects in real time with the stored thresholds to achieve rapid classification and discrimination without calling the clustering engine in real time.

[0136] The system of the present invention This invention provides a system for classifying the health status of people living in high-altitude areas. The system can be an electronic device, including but not limited to: smartphones, tablets, personal computers, servers, terminals, or other intelligent terminals with data processing capabilities. The system can also be a computer-readable storage medium, such as a hard disk, optical disk, solid-state drive, read-only memory, or flash memory, storing a computer program that, when executed by one or more processors, enables the data processing flow. Furthermore, the system can also be a computer program product containing computer instructions that, when executed by a computer, cause the computer to perform all or part of the steps of the data processing flow.
[0137] The data processing flow can be loaded, deployed, or run on any of the aforementioned electronic devices. Through the collaboration of hardware resources and the software logic defined in the flow, the system can complete specific data acquisition, transmission, calculation, analysis, storage, or presentation tasks.
[0138] The main advantages of this invention include: (1) This invention introduces a multi-dimensional indicator system covering physiological health, mental health, cognitive health and sleep health, and uses the CRITIC algorithm to capture the asynchronous change characteristics between physiological indicators and cognitive indicators. This effectively avoids the false negative results that may be obtained based on a single physiological dimension, and can identify hidden sub-health risks earlier and more accurately.
[0139] (2) The present invention adopts the “CRITIC-EWM” two-layer pure objective combined weighting architecture based on data fluctuation characteristics and information entropy. This architecture is completely driven by real-time data of the test group, effectively avoiding the weight bias caused by subjective experience, and ensuring the objectivity and rigor of the evaluation model in complex medical-engineering cross-situation.
[0140] (3) This invention breaks through the limitations of traditional solutions that only focus on human physiological signs and constructs a four-dimensional assessment system that integrates physiological, psychological, cognitive and sleep health.

[0141] (4) The present invention introduces a mechanism of pre-clustering diversion and back-end clustering to generate hierarchical boundaries. Instead of relying on static global fixed health thresholds, it can perform dynamic hierarchical evaluation of physical and mental health, which improves the robustness of the model in extreme environments.
[0142] (5) This invention not only outputs health rating conclusions, but also provides source-based interventions based on the shortcomings in the four-dimensional scores. For individuals in a sub-healthy state, the system can output differentiated proactive intervention strategies such as "medical repair" (e.g., oxygen inhalation, forced rest), "psychological adjustment" (e.g., mindfulness relaxation training), and "sleep intervention" (e.g., improving environmental ventilation rate, controlling noise) based on the assessment results, transforming risk warnings into actionable closed-loop management recommendations. This mechanism effectively reduces the subjective blind spots and costs of manual screening, and improves the efficiency and operability of large-scale health protection for the plateau population.
[0143] The present invention will be further illustrated below with reference to specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

To provide a deep understanding of the invention, many specific details will be included in the following description. The invention may also be practiced without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description.
[0144] Example 1: A method for classifying and assessing the health status of high-altitude populations based on a four-dimensional functional state space. This embodiment proposes a method for classifying and assessing the health status of high-altitude populations based on a four-dimensional functional state space. The specific steps are as follows: Step S1: Acquisition of multidimensional heterogeneous data 1. Map functional characteristic data to a four-dimensional space of "physiological-psychological-cognitive-sleep": (1) Physiological functional dimensions include, but are not limited to: respiratory system parameters: blood oxygen saturation, vital capacity and respiratory rate; nervous system parameters: resting heart rate and multidimensional heart rate variability (HRV) index; circulatory system parameters: blood pressure, hemoglobin concentration, hematocrit (HCt), red blood cell count, blood uric acid (UA) and other common blood biochemical indicators; digestive and metabolic parameters: body mass index (BMI) and weight maintenance level.
[0145] The multidimensional heart rate variability indicators include: time domain indicators: standard deviation of normal heart rate interval (SDNN), root mean square of continuous differences (RMSSD); frequency domain indicators: total power, low frequency (LF), high frequency (HF), low frequency / high frequency ratio (LF / HF); and nonlinear dynamic indicators: sample entropy, Poincaré dimension, approximate entropy, detrended fluctuation analysis (DFA), and correlation dimension (CD).
[0146] (2) The psychological and emotional dimensions include: anxiety score obtained based on the Generalized Anxiety Disorder Scale (GAD-7) and depression score obtained based on the Depression Screening Scale (PHQ-9).
[0147] (3) The cognitive efficacy dimension includes: the cognitive error frequency score obtained based on the Cognitive Failure Questionnaire (CFQ); (4) Sleep health dimension characteristic data include: objective physiological sleep indicators: the proportion of deep sleep, REM sleep, light sleep, number of nighttime awakenings, total awake time, and time in bed and total sleep time collected using wearable devices; subjective assessment indicators: the scores of seven components based on the Pittsburgh Sleep Quality Index (PSQI) scale, including subjective sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep disorders, use of hypnotics, and daytime dysfunction; circadian rhythm indicators: the degree of circadian rhythm disorder calculated based on the absolute difference between the midpoint of sleep on weekdays and the midpoint of sleep on rest days.
[0148] 2. Individual behavioral and environmental exposure characteristics were obtained, including: natural environmental exposure parameters (calculated based on the altitude of the place of residence before entering the plateau) altitude difference and time spent in the plateau; daily activity and work-rest load parameters: daily work / study time, monthly frequency of irregular work and rest, etc. Step S2: Preprocessing of multidimensional heterogeneous data Because physiological, psychological, cognitive, and sleep indicators have different dimensions, and because there are positive indicators (higher values are better, such as blood oxygen) and negative indicators (lower values are better, such as heart rate), range standardization is required. Positive indicator calculation formula: Formula for calculating negative indicators: The range of values is: ; Indicates the first The first subject was on the The original observed values of each evaluation index ( ; ), This represents its dimensionless value after standardization. and These represent the sample population at the 1st... The maximum and minimum values of each evaluation indicator.
[0149] Step S3: Pre-splitting of exposed features based on K-means++.
[0150] Extracting environmental exposure feature vectors from subjects To overcome the shortcomings of random initialization in traditional algorithms, the K-means++ algorithm is used to maximize the distance between initial cluster centers. Then, the objective function is minimized iteratively. The study population was adaptively divided into three groups: acute exposure group, chronic cumulative high-load group, and conventional steady-state adaptation group. This step aimed to eliminate baseline errors caused by differences in exposure backgrounds, ensuring that subsequent evaluations were conducted under homogeneous exposure conditions. Furthermore, the adaptive and stable division of subjects into different exposure background groups ensured highly targeted and reproducible weighting in subsequent assessments. : Represents the objective function, which is the sum of the squared distances from each sample point to its class center. This is achieved through iteration... minimize; : indicates the first division A subgroup of exposed features; : No. Environmental and lifestyle exposure feature vectors of each subject; : indicates the first The cluster center (centroid) of a subgroup.
[0151] Step S4: First-level CRITIC micro-weighting: Within each subgroup, micro-weights are calculated using the volatility and conflict of the indicators. : Calculate the contrast intensity (i.e., standard deviation): ; Based on the Pearson correlation coefficient among indicators Conflict Computation : ; The combination of contrast intensity and conflict generates micro-weights: .
[0152] This step aims to capture the asynchronous changes between physiological indicators and sleep / cognitive indicators, and to decipher the "masking effect" of physiological compensation on latent damage. : No. The standard deviation of an indicator reflects the intensity of its fluctuation and its discriminative power within a subgroup. : No. within subgroup The average of each indicator. :index With indicators The Pearson correlation coefficient between them is used to characterize information redundancy. : No. Quantitative values of conflict for each indicator; The larger the value, the better the indicator can break through the masking effect of physiological compensation; It is the first The micro-level "weight values" that are ultimately assigned to each indicator.
[0153] Step S5: Second-level EWM macro-weighting The independent composite scores of four dimensions (physiological, psychological, cognitive, and sleep) are used as new state-space variables, and the information entropy is calculated using the entropy weight method. This allows for the calculation of the macro-spatial weights of the four macro-dimensions. .
[0154] 1. Calculate the subjects' overall scores across all dimensions. : Based on the micro-indicator weights obtained in step S3 Compared with the standardized values after step S1 Calculate the first The first subject was on the Overall score across major dimensions : , in, For the first Dimensions ( The score includes the number of indicators. This score reflects an individual's performance level in a single dimension, such as physiological function, psychological and emotional state, cognitive efficacy, or sleep health.
[0155] 2. Calculate the weighting of dimensional scores. : To calculate the entropy value, the individual score needs to be normalized within the sample pool of that subgroup to obtain the first value. The first subject was on the Weight of scores in each dimension : , Where m is the total number of samples in the subgroup.
[0156] 3. Calculate the information entropy of each dimension. : The information entropy formula is used to measure the dispersion of data distribution across four dimensions: , in, It is the first Information entropy in a large dimension The smaller the value, the more information that dimension provides, and the higher its weight in the overall health assessment.
[0157] 4. Calculate the macroscopic spatial weights , in, These correspond to the macroscopic spatial weights of the four dimensions: physiological, psychological, cognitive, and sleep. This step aims to prevent highly fluctuating physiological data from masking the evaluative effectiveness of the psychological, cognitive, and sleep dimensions, ensuring the balance of the four-dimensional space, starting from the purity of information.
[0158] Step S6: TOPSIS Spatial Ranging and Adaptive Grading 1. Construct a weighted normalized matrix and extract the ideal solution: The system is based on the individual's comprehensive score and macro weights across all dimensions. Automatically extract the positive ideal solution (population optimal state vector) of the subject group under the current exposure background. ) and negative ideal solution (population range state vector) ).
[0159] 2. Calculate the health relevance score. : Calculate the individual state vector and the positive ideal solution ( and negative ideal solution ( Euclidean distance of ) , in , The larger the value, the closer the individual's overall functional state is to the ideal steady state.
[0160] 3. Adaptive grading based on K-means++: Calculate the set of individual health proximity scores Then, set the number of clusters. (These correspond to pathological risk, functional decline in sub-health, and homeostasis of health, respectively).
[0161] Cluster center initialization: from the score set A sample point is randomly selected as the first initial cluster center. For the set... Any remaining samples Calculate the Euclidean distance from the current nearest existing cluster center. Calculate the probability that each sample will be selected as the next new cluster center. The probability With distance It is directly proportional to the square of, and the formula for its calculation is: , Based on the stated probability The next new cluster center is selected using a roulette wheel method. This process is repeated until all cluster centers have been selected. Initial cluster centers. This step effectively avoids the pitfall of traditional random initialization, which easily gets trapped in local optima. Iterative optimization of the objective function: (1) Iterative clustering and centroid update: Calculate the set Each sample point in the above The Euclidean distance between cluster centers is calculated, and each sample point is assigned to the cluster with the smallest distance. After the division, the centroid of each cluster is updated. The updated formula is as follows ,in For the first Sample size within each cluster The score is given to the samples within the cluster.
[0162] By iteratively dividing the samples and updating the centroids, the sum of squared errors within the cluster is minimized. Until the algorithm converges. The sum of squared errors within the cluster. The objective function is: .
[0163] (2) Dynamic hierarchical boundary threshold extraction: After the algorithm converges, the final centroids corresponding to the three clusters are extracted and sorted by numerical value, and are respectively denoted as the centroids of the "pathological risk" cluster. "Sub-health functional decline" cluster center and the "healthy homeostasis" cluster centroid By calculating the arithmetic mean of adjacent centroids, the hierarchical boundary threshold for generating the current data context is extracted. Calculate the pathological risk boundary threshold : , Calculate the healthy steady-state boundary threshold : .
[0164] The final output is a dynamic evaluation standard sequence. It is used to adaptively grade and warn about the physical and mental health status of subjects.
[0165] At the application level, this step is divided into two stages: "benchmark extraction" and "individual mapping," and has a dynamic update mechanism. Benchmark extraction phase: Generating hierarchical boundary thresholds using initial subject population data. and This serves as an evaluation benchmark within this environmental context; Individual mapping stage: For newly added subjects, their proximity score is directly assigned. With the already generated , Comparisons can be made without re-triggering clustering calculations; Step S7: Sample-driven iterative update mechanism.
[0166] The cumulative sample size in the multidimensional dataset is monitored in real time. When the current cumulative sample size reaches an integer multiple of the initial baseline sample size (trigger mechanism), the calculation and clustering iteration process in steps S2 to S6 is re-executed to update the evaluation criteria for the plateau population. and This will allow us to obtain an updated health status classification model for people living in high-altitude areas, enabling adaptive evolution of the standard.
[0167] Differentiated proactive health intervention strategies based on grading results: The system uses a model-based hierarchical assessment and outputs differentiated intervention instructions based on the "weakest link effect" of multidimensional scores. 1. Status determination triggering mechanism: when When the condition is determined to be "healthy and stable", the system will only perform routine recording and will not trigger intervention.
[0168] when At that time, it was determined to be "sub-health functional decline".
[0169] when When the condition is identified as "pathological risk," the system triggers the highest level of medical warning.
[0170] 2. Identifying the root causes of weaknesses and implementing multi-dimensional coordinated interventions: For subjects who triggered the intervention, the system compared their weighted independent scores across four dimensions: physiological, psychological, cognitive, and sleep. Identify the "weakness dimension" with the lowest score (i.e., ), and map the corresponding execution strategy: If the disadvantage is physiological function: the system outputs "active medical repair" instructions to the terminal, such as increasing the frequency of oxygen inhalation, forcing rest, and forcibly reducing the physical activity load.
[0171] If the disadvantage dimension is psychological emotion or cognitive performance: the system outputs "psychological adjustment" instructions, such as arranging mindfulness relaxation training, suspending high cognitive load activities, etc.
[0172] If the disadvantage dimension is sleep health: the system triggers sleep intervention commands, including outputting "physical environment control strategies" to the smart hardware terminal (such as increasing the ventilation rate of the sleep environment, reducing the carbon dioxide concentration of the sleep environment, increasing the light blocking of the sleep environment, controlling the noise of the sleep environment, etc.), or outputting health suggestions to the management terminal (such as suggesting optimization of the sleep cycle, etc.). Example 2: A Health Status Grading Assessment System for Plateau Population Based on a Four-Dimensional Functional State Space Referring to Example 1, the present invention also proposes a health status grading assessment system for plateau populations based on a four-dimensional functional state space, comprising the following functional modules: (M1) Input module: The input module is configured to input data, which includes a multidimensional dataset of the test subject (i.e., an individual from the plateau population). This module is used to execute method step S1. The module further includes: The physical signs and sleep data acquisition unit collects objective physical signs data such as blood oxygen saturation and multidimensional heart rate variability (time domain, frequency domain, and nonlinear indicators) of the target subjects through wearable devices (such as smart bracelets and dynamic ECG patches) and portable medical instruments; it also collects objective sleep health data such as the proportion of deep sleep, REM sleep, light sleep, number of nighttime awakenings, total awake time, time in bed, and total sleep duration; and calculates the midpoint of sleep on weekdays and rest days based on the attendance system, outputting social jet lag (SJL) to quantify the degree of rhythm disorder.
[0173] Environmental and individual behavioral exposure acquisition: The altitude difference, time spent in high-altitude areas, and daily activity and rest load parameters (daily work / study time, frequency of irregular work and rest, etc.) are obtained through the management system interface to generate environmental and individual behavioral exposure feature vectors.
[0174] Questionnaire and rhythm input unit: The cognitive failure questionnaire (CFQ), psychological scale scores (GAD-7 and PHQ-9 scores), and PSQI sleep quality scale scores of the subjects are obtained through smart terminals (such as mobile phone applets or tablets).
[0175] (M2) Analysis Module: The analysis module analyzes the input data and obtains the analysis results. This module is the core engine of the system and specifically includes the following units: (m2.1) Grading Unit: The grading unit is configured as a health status grading model for a plateau population. This model is constructed using the method described in Example 1 and grades the subjects based on a multidimensional dataset. This unit integrates the computational logic of method steps (S2) to (S6): Preprocessing and pre-processing engine: Perform range standardization in step S2 and then perform step (S3) to divide the test objects into corresponding homogeneous exposed feature subgroups using the K-means++ algorithm.
[0176] The dual-layer objective computing power weighting engine executes steps S4 and S5, using the CRITIC algorithm to independently calculate the micro-weights of physiological, psychological, cognitive, and sleep indicators within a subgroup (breaking the physiological compensation masking effect), and using the entropy weight method (EWM) to calculate the macro-spatial weights of the four dimensions. Spatial ranging and hierarchical mapping engine: Executes step (S6) of TOPSIS spatial ranging to calculate the comprehensive health proximity of the test object. This unit is equipped with a threshold memory to solidify the pathological risk boundary threshold T1 and the health homeostasis boundary threshold T2 generated by clustering. For the real-time input score of the test object, it is directly compared with the stored thresholds T1 and T2 to quickly obtain the hierarchical result (health homeostasis, sub-health functional decline, or pathological risk).
[0177] (m2.2) Intervention Unit: The intervention unit is configured to execute follow-up strategies based on the grading results. If the subject is in the "pathological risk" or "sub-health functional decline" category, the unit traces back to the lowest-scoring weakness dimension to determine and generate the corresponding intervention strategy: If the dimension with the lowest overall score is physiological function, then an "active medical repair" strategy is generated (such as increasing the frequency of oxygen inhalation, mandatory rest, or mandatory reduction of physical activity load).
[0178] If the dimension with the lowest overall score is psychological and / or cognitive efficacy, then a "psychological adjustment" strategy is generated (such as arranging mindfulness relaxation training, postponing high cognitive load activities, etc.).
[0179] If the dimension with the lowest overall score is sleep health, then a "sleep intervention" strategy is generated (including linking smart hardware to improve the ventilation rate of the sleep environment, reduce carbon dioxide concentration, increase light blocking, control noise, or generate nighttime oxygen supplementation instructions).
[0180] (m2.3) Update Unit: The update unit is configured to monitor the cumulative sample size of the multidimensional dataset input by the (M1) input module. This unit is used to execute step (S7), which automatically calls back and executes the calculation and clustering process of steps (S2)-(S6) when the current cumulative sample size meets the preset trigger mechanism (reaching an integer multiple of the initial baseline sample size) to update the boundary thresholds T1 and T2 in the memory, so that the (m2.1) grading unit can always be configured to update the plateau population health status grading model to adapt to the latest population characteristics.

[0185] Example 3: Specific application verification and effect analysis of the evaluation method of the present invention To further verify the effectiveness of this invention and the specific execution logic of each algorithm module, this embodiment conducted a model verification and numerical calculation test. It should be specifically noted that the sample data used in this embodiment is only used to intuitively verify the coherence and feasibility of the adaptive pre-diversion and objective combination weighting algorithm logic of this invention through specific numerical calculations. The evaluation method described in this invention highly relies on purely data-driven mathematical measures (such as spatial proximity calculation and dynamic clustering threshold generation). Its underlying computational architecture achieves a high degree of decoupling from the prior norm database of a specific population, no longer relying on fixed static thresholds. Therefore, in practical applications, this method is not limited to the specific altitude or sample distribution shown in this embodiment, but can dynamically generalize and automatically calibrate the evaluation boundary based on the actual characteristics of the input data, possessing broad applicability and robustness under different high-altitude exposure scenarios.
[0186] Based on a typical application scenario in a high-altitude living environment, observational sample data from 30 subjects in the same batch were extracted as the evaluation benchmark group for algorithm derivation. To clearly demonstrate the derivation logic of this invention, this embodiment selects two core indicators each from the dimensions of physiological function, psychological emotion, and sleep health, and one core indicator from the cognitive efficacy dimension as a representative. The typical data calculation process of three of the most representative core subjects (A, B, and C) is explained in detail below: 1. S1: Provides a multidimensional dataset of high-altitude populations. Typical exposure and functional characteristics data were obtained from three core subjects and the remaining samples from the same batch (a total of 30 people). The selected representative indicators and the raw data of the subjects are shown in Table 1.
[0187] Table 1. Raw data of three core subjects Among them, A: climbed 3500m in altitude, stayed for 2 days, worked an average of 10 hours per day, and had no irregular work schedules per month; B: climbed 1500m in altitude, stayed for 200 days, worked an average of 12 hours per day, and had two irregular work schedules per month; C: climbed 1500m in altitude, stayed for 500 days, worked an average of 8 hours per day, and had no irregular work schedules per month.
[0188] 2. S2: Preprocessing of Cube Datasets The system iterates through all samples in the current batch and automatically extracts the global maxima of various functional indicators. ) and minimum value ( (This serves as the evaluation benchmark boundary.) Physiological extremes: Blood oxygenation limit Heart rate limits .
[0189] Psychological extreme value: GAD-7 limit PHQ-9 boundary .
[0190] Cognitive extremes: CFQ limits .
[0191] Sleep extremes: PSQI limits Nighttime wakefulness limits The system performs range standardization mapping according to the formula in Example 1.
[0192] For positive indicators, a formula is used. Taking blood oxygen level B as an example, let's substitute the values into the calculation: .
[0193] For negative indicators, the formula is used. Taking B's CFQ cognitive score and heart rate as an example, let's substitute them into the calculation: ; .
[0194] Similarly, by substituting into the formula, we finally obtained the standardized dimensionless score matrix of the three subjects, A, B, and C (retaining two decimal places, with values ranging from 0 to 1, and higher scores indicating healthier function), as shown in Table 2.
[0195] Table 2. Normalized data of three core subjects Note: In actual system operation, each dimension includes, but is not limited to, the aforementioned complex indicators. This is a brief description of the core logic of the embodiment.
[0196] 3. S3: Pre-processing of environmental exposure features based on clustering algorithm Extract environmental exposure and daily routine data from the subjects and normalize them into exposure feature vectors. , respectively corresponding .
[0197] Based on the consensus in high-altitude medicine regarding the acclimatization stages of populations (i.e., acute exposure period, chronic attrition period, and routine acclimatization period), the number of clusters is pre-defined. The system uses the K-means++ algorithm for training and ranging. (1) Distance probability initialization and centroid iterative calculation: Three centroids are initialized using a distance probability weighting method to avoid local optima, and samples are continuously assigned to the nearest cluster using standard Euclidean distance. In the update phase of each iteration (until the objective function converges), the system redetermines the centroid coordinates by calculating the arithmetic mean of the feature vectors of all samples within the cluster, based on the intra-cluster partitioning results.
[0198] Substitute into the centroid update formula .
[0199] Taking the final convergence calculation of the chronic cumulative high burden group (GB group, including 10 samples including subject B) as an example: The system extracts the standardized exposure feature vectors of the 10 samples in this group and performs column matrix summation: Similarly, using the eigenvector summation and averaging method described above, the final convergence centroids of the other two groups can be accurately calculated: (Acute exposure group center of gravity): (Conventional steady-state adaptive population center of mass): (2) Individual ranging and triage execution: Taking the standardized exposure feature vectors of three core subjects as an example: Subject A (elevation 3500m, 2 days in high-altitude environment, 10 hours of high-intensity work per day, no irregular schedule): Subject B (elevation 1500m, 200 days in high-altitude area, 12 hours of work per day, irregular work and rest twice a month): Subject C (elevation 1500m, 500 days in high-altitude area, 8 hours of work per day, no irregular work and rest schedule): Calculate the squared standard Euclidean distance from the subject to the centroid of each subgroup ( Taking subject B as an example, calculate the squared distances from her to the three centroids: because The squared distance value ( Based on the principle of minimum distance, Subject B was precisely classified into the "Chronic Cumulative High Load Group (GB Group)". Similarly, after distance measurement by the algorithm, Subject A was classified into the "Acute Exposure Group (GA Group)" and Subject C into the "Routine Steady-State Adaptation Group (GC Group)". Subsequent steps S3 to S5 were performed independently within each subgroup. This process completely eliminated the error of manual subjective prior classification.
[0200] 4. S4: Weighting within the micro-dimension based on objective weighting method (taking the GB group to which subject B belongs as an example) After clustering and triage, the system extracted the independent dimensional data within the GB group (a total of 10 subjects) and used the CRITIC algorithm to calculate the contrast intensity (unbiased standard deviation) of each indicator. ) and conflict (derived from Pearson correlation coefficient) ), and then extract micro-weights.
[0201] (1) Basic data extraction and standardization: Taking the physiological function dimensions of the GB group (with blood oxygen and heart rate as two indicators) as an example, the original data and standardized scores of 10 subjects recorded by the system (combined with the global extreme values of S1: blood oxygen limit [72,99], heart rate limit [58,125]) are shown in Table 3.
[0202] Table 3. Raw data and standardized scores of 10 subjects The mean within the group was calculated as: mean blood oxygen score. mean heart rate score .
[0203] (2) Calculate the contrast intensity (standard deviation) ): Substitute into the standard deviation formula , and then proceed with the derivation: Blood oxygen variance , ; Heart rate variance , .
[0204] (3) Calculate the conflict (correlation coefficient) and ): The internal redundancy of blood oxygen and heart rate sequences was calculated using the Pearson correlation coefficient formula. Substituting the matrix data, the calculation yields: Covariance numerator: ∑≈0.1470; denominator product term: Correlation coefficient .
[0205] Substituting into the conflict formula : Blood oxygen conflict ; Heart rate conflict .
[0206] (4) Extracting information carrying capacity ( ) and final micro weights ( ): Substitute into the formula Assess the overall amount of information: Blood oxygen information: ; Heart rate information content: .
[0207] Substitute into the weight normalization formula : Blood oxygen microweight ; Heart rate microweight .
[0208] Similarly, the above-mentioned internal indicators for the dimensions of psychological and emotional health and sleep health were applied. and Matrix operations. The final micro-weights for the four dimensions within the GB group are fully allocated as follows: Physiological (blood oxygen) Heart rate ); Psychology (GAD-7) PHQ-9 Sleep (PSQI) Number of times of waking up Cognition is a single indicator and is directly counted as... .
[0209] (5) Intra-dimensional score integration: Substitute into the formula Calculate the four-dimensional independent composite score of subject B: Physiological score ; Psychological score ; Cognitive score ; Sleep score .
[0210] At this point, through rigorous calculation of underlying indicators, the current state of subject B was precisely quantified: it exhibited a very strong "physiological compensation masking effect" (physiological score as high as...). However, due to long-term high-intensity exposure, their cognition and sleep have shown severe, hidden impairment, with scores of only [insert scores here]. and ).
[0211] 5. S5: Calculation of Comprehensive Score and Determination of Macro-Spatial Weights (1) Standardization of local range within groups and matrix construction: The four-dimensional comprehensive score matrix calculated in S3 for 10 subjects in the GB group was extracted, and the intra-group extreme values of each dimension were extracted (e.g., the intra-group range of the physiological dimension was 0.967 - 0.420 = 0.547). A positive standardization formula was then used. To avoid zero-value errors in subsequent logarithmic calculations, the dimensionless score matrix of the 10 subjects in the group was calculated, as shown in Table 4.
[0212] Table 4. Raw data and standardized scores of 10 subjects Note: For ease of formatting, the table above is consistently rounded to three decimal places. GB_Sample 1 marked with an asterisk in the table represents the range baseline sample for each dimension; its underlying actual output value is... (Right now This non-zero minimum value ensures that the system can be successfully invoked in subsequent steps. It can perform operations without causing abnormal overflows.
[0213] (2) Calculate the characteristic proportion ( ): By summing the feature scores of each column in the above matrix vertically, the sum of the within-group scores for each dimension is obtained as follows: Total physiological score ; Total psychological score ; Total cognitive score ; Total sleep score .
[0214] Substitute into the characteristic proportion formula Extract the information weight of subject B in each dimension: Physiological specific gravity Psychological weight ; Cognitive proportion Sleep proportion .
[0215] (3) Calculate information entropy ( ) and the coefficient of difference ( ): Traverse the entire group's weight matrix Substitute into the information entropy formula (Among them, sample size) constant coefficients From the perspective of physiological function ( Taking the calculation of information entropy as an example, the physiological proportions of 10 subjects in the group are extracted. Calculate them separately Value. Based on subject B ( For example: .
[0216] Similarly, the same logarithmic product operation was performed on the remaining 9 subjects in the group, and the results were summed to obtain the logarithmic sum of the physiological dimensions for the entire group: .
[0217] Substituting the coefficients, we obtain the final physiological information entropy: .
[0218] Similarly, the information entropy of the other three dimensions can be derived: Psychological entropy Cognitive entropy Sleep entropy .
[0219] Then, substitute the formula for the coefficient of difference. The four-dimensional dispersion index is obtained as follows: Physiological difference coefficient ; Psychological difference coefficient ; Cognitive Difference Coefficient ; Sleep difference coefficient .
[0220] (4) Generate the final macroscopic spatial weights ( ): First, calculate the sum of the difference coefficients across the four dimensions, using this as the denominator for weight normalization: .
[0221] Substitute into the normalization formula The system ultimately outputs the macroscopic spatial weighting vector for the GB group: Physiological function weight Psychological and emotional weighting ; Cognitive efficacy weight Sleep health weight .
[0222] This step, through the rigorous and traceable calculations described above, objectively demonstrates that the target population exhibits the greatest data dispersion (variance coefficient) in the "cognitive efficacy" dimension. (Ranked first), containing the most effective information on individual differences. Based on this, the algorithm adaptively compressed the weights of the physiological dimensions that showed convergent performance (reducing them to...). The weight of the cognitive dimension representing differences in latent damage was increased (to a higher level). This completely eliminates the evaluation masking effect caused by simple physiological compensation from the mathematical foundation.
[0223] 6. S6: TOPSIS Spatial Ranging and Subgroup-Specific Dynamic Threshold Extraction Combining the extracted macro-weights, the proximity of an individual to the optimal / inferior state of their subgroup is calculated, and the state boundary is dynamically generated. Taking subject B (GB group) as an example, the derivation process is as follows: (1) Constructing the weighted normalization matrix and extracting the ideal solution: The four-dimensional comprehensive score matrix in S3 ( ) and the macroscopic weights extracted by S4 ( Multiply each term by the other to construct a weighted feature matrix. The weighted score of Subject B is: Physiological weighted score ; Psychological weighted score ; Cognitive weighted score ; Sleep weighted score .
[0224] Traverse the GB weighted matrix and extract the positive ideal solution representing the optimal state. ) and the negative ideal solution representing the range state ( ): Positive ideal solution: ; Negative ideal solution: .
[0225] (2) Euclidean distance measurement and proximity ( )calculate: Substituting into the Euclidean distance formula and Calculate the distance index of subject B: Distance to the ideal solution: Distance to negative ideal solution Substitute into the proximity formula The overall health relevance of subject B was determined as follows: .
[0226] Similarly, the closeness scores of the remaining 9 subjects in the GB group were calculated, forming the closeness set of this subgroup. Executing the above logic within both the GA and GC groups yields the following result: A ; C .
[0227] (3) Dedicated dynamic threshold generation: To achieve adaptive grading without prior knowledge, the closeness scores of 10 subjects in the GB group were analyzed. ) Sets of independent K-means++ clustering algorithms (assuming) ).
[0228] During the iterative convergence phase, the system accurately divides these 10 one-dimensional coordinate points into three state clusters, and extracts the final centroid μ by averaging the proximity of samples within the cluster. Pathological risk cluster (1 sample): centroid ; Healthy homeostatic cluster (1 sample): centroid .
[0229] Sub-health functional decline cluster (8 samples, including subject B): .
[0230] Using the formula of the mean of adjacent centroids The system generates adaptive state boundaries specific to the current camp background for the GB group in real time: Pathological risk boundary Healthy homeostasis boundary .
[0231] Similarly, the adaptive boundary of the GA group is calculated as follows: ; GC group adaptive boundary is .
[0232] 7. S7: Sample-driven iterative update mechanism for evaluation criteria To ensure the accuracy of the evaluation criteria in long-term applications, the system incorporates a sample-driven trigger update mechanism.
[0233] Update trigger determination: The system counts in real time the total number of subjects who have completed the evaluation within each subgroup (GA, GB, GC). Set the update step size coefficient to... (As in this embodiment, let) When the cumulative sample size of the current subgroup... Reaching the initial baseline sample size When the number of people increases to an integer multiple (e.g., from 30 to 60, 120, etc.), the system automatically triggers the "Evaluation Criteria Recalibration" command.
[0234] Calculation logic iteration: 1. The system retrieves the full data within this subgroup. Set of health relevance scores of 100 subjects 2. Rerun the K-means++ clustering engine in step (3) of S5 to re-identify cluster centroids on a larger sample base. 3. Using formulas and Calculate and update the new hierarchical boundary threshold for this scenario.
[0235] Technical effect: This "learn as you go" model ensures It can continuously adapt and fine-tune as high-altitude activity data accumulates. For example, as the overall adaptation level of people moving to a certain area improves, the system will automatically identify and slightly shift the threshold, so that the evaluation criteria always align with the current real-world health benchmarks of the population, avoiding the problem of traditional fixed standards becoming ineffective at different times.
[0236] 8. Differentiated proactive health intervention strategies based on triage results Overall relevance of individuals The logic is determined by setting the specific dynamic threshold of its subgroup and then outputting the optimization closed-loop intervention instruction: For subject A (GA group): Decision logic: .
[0237] The system accurately determines the state as "pathological risk" and immediately triggers the highest level of physical intervention, outputting a warning command to the terminal to "forcefully stop high-intensity activities and immediately intervene with medical care".
[0238] For Subject B (GB group): Decision logic: .
[0239] In traditional single physiological assessments, HBV is easily misjudged as healthy due to its relatively good blood oxygen / heart rate compensation. This system, through observational weighting and distance extrapolation, accurately identifies HBV as being in a state of "sub-healthy functional decline," such as... Figure 3 As shown in the multidimensional health assessment radar chart, although Subject B's physiological functions were close to the health baseline due to compensatory mechanisms, there was a significant collapse in his cognitive efficacy dimension. Therefore, targeted intervention strategies were sent to his personal smart terminal or related early warning system: Subject B was advised to postpone high-cognitive-load activities (such as driving, precision construction work, or complex decision-making and planning) to prevent safety risks caused by cognitive impairment. Simultaneously, it was suggested to coordinate with environmental control devices or personal health assistants to adjust daily routines, reduce the frequency of unconventional activities, and push proactive adjustment programs such as mindfulness meditation and high-altitude rhythmic breathing training to effectively alleviate nervous fatigue and accelerate the repair of cognitive and physical functions.
[0240] For subject C (GC group): Decision logic: .
[0241] The system determines that the state is "healthy and stable" and records the current observation data as a normalized health baseline, recommending that the current work and rest patterns be maintained.
[0242] This embodiment demonstrates that even when facing complex groups like Subject B, whose physiological indicators are in a compensatory state but who are generally in a state of sub-health depletion, this invention can completely break through the masking effect through a purely data-driven CRITIC-EWM two-layer combined weighting, and accurately locate the highly concealed "sub-health state" within... Within the dynamic mathematical range, the system completely abandons the constant settings that rely on expert experience. From the underlying mathematical architecture, it has the ability to generalize and be implemented in different altitudes and physical conditions, effectively solving the core pain point of missed assessments and warnings for sub-healthy groups in high-altitude health evaluations.
[0243] Example 4: Evaluation of the model's effectiveness and robustness in large-scale simulations To verify the effectiveness and robustness of the plateau population health status classification assessment method described in this invention under large-scale data input scenarios, this embodiment uses a scheme of "baseline feature extraction combined with large-scale Monte Carlo extension" to conduct systematic simulation tests.
[0244] 1. Prior extraction of features based on the feature distribution of core samples Observational sample data were extracted from 30 subjects in the same batch. Based on the altitude stay duration or physiological exposure characteristics of the target population, they were clustered into several exposure subgroups with independent data distribution attributes (such as the first exposure subgroup, the second exposure subgroup, etc.). The evaluation system of this invention was used to complete the four-dimensional double-layer weighted calculation and proximity calibration of physiological, psychological, cognitive, and sleep aspects. Through statistical analysis, the probability density distribution law of the multidimensional index fluctuation variance and the comprehensive proximity score of the target population was obtained, and these were used as prior statistical parameters for subsequent large-scale simulation tests.
[0245] 2. Large-scale data expansion and testing based on Monte Carlo algorithm To verify the system's generalization ability under massive datasets, this embodiment introduces a Stratified Monte Carlo algorithm for data augmentation based on the extracted prior distribution patterns. According to the distribution weights of each exposed subgroup, a large-scale simulation validation set containing N=500 samples was generated through targeted augmentation.
[0246] Subsequently, to establish an objective comparison benchmark, this embodiment uses a preset multi-dimensional feature threshold boundary to mark the benchmark state of 500 extended samples, forming a verification reference gold standard. Specifically, the benchmark marking rules are set as follows: (1) Pathological risk status marking: When any core physiological parameter (such as blood oxygen, heart rate, etc.) in the multidimensional monitoring data of the sample exceeds the preset safety lower limit / upper limit, or the score of any core psychological scale exceeds the preset clinical warning threshold, an over-boundary alarm is triggered and it is marked as pathological risk. (2) Health homeostasis labeling: When the multidimensional monitoring data of a sample simultaneously meet the full-dimensional compliance conditions (i.e., all physiological parameters are within the preset normal range and all psychological scale scores are within the preset health baseline), it is labeled as health homeostasis. (3) Marking of sub-health functional decline: When the sample data does not trigger the pathological risk over-limit rule and fails to fully meet the conditions for achieving the health homeostasis, it is defined as a transitional state and marked as sub-health functional decline.
[0247] Those skilled in the art should understand that the specific physiological parameter thresholds and scale scores mentioned above are merely specific application examples for calibrating simulation benchmark data in this embodiment. In practical applications, the system can customize the above rules and conditions according to specific altitudes, types of daily activities, and employer management regulations, and this does not limit the scope of protection of the present invention.
[0248] Finally, the calculated continuous scores of 500 cases are input into the exclusive dynamic classification thresholds (i.e., the pathological judgment line and steady-state judgment line corresponding to each subgroup) generated adaptively based on the K-means++ algorithm for each exposure subgroup for automatic judgment, and are aligned and verified with the above-mentioned baseline state marking results.
[0249] 3. Verification Results and Analysis of Beneficial Technical Effects Through comparison and verification, this embodiment outputs the following two core verification charts: (1) Validation using multi-class receiver operating characteristic (ROC) curves: see attached. Figure 4 As shown, with a large-scale expanded data input of N=500, the areas under the curve (AUC) of this evaluation model for predicting the three states of "health homeostasis", "sub-health functional decline", and "pathological risk" are 0.964, 0.884, and 0.824, respectively. This result demonstrates that the computational logic proposed in this invention does not exhibit algorithm failure or overfitting under large data inputs and possesses extremely high risk screening sensitivity.
[0250] (2) Verification of the accuracy of the multi-level confusion matrix: as shown in the appendix. Figure 5 As shown, 500 simulated samples were classified according to the dynamic classification threshold adaptively generated by combining subgroup features in step S5 of this invention. The results show that 409 samples were accurately predicted to fall on the main diagonal of the confusion matrix, and the overall classification accuracy reached 81.8%. This result effectively proves that the exclusive dynamic boundary threshold generated by this invention can not only keenly capture functional decline and pathological states, but also greatly control the false alarm rate and false negative rate of the ineffective system in the extreme environment of high altitude, and has extremely high engineering application feasibility.

Furthermore, it should be understood that after reading the foregoing teachings of this invention, those skilled in the art can make various alterations or modifications to this invention, and these equivalent forms also fall within the scope defined by the appended claims.

If the overall health closeness of the tested object is [value missing], it indicates that the object is in a healthy homeostasis state; if the overall health closeness of the tested object is [value missing], it indicates that the object is in a healthy homeostasis state. If the test subject is at pathological risk, then the overall health proximity C of the test subject satisfies the following conditions. If so, it indicates that the subject is in a state of sub-health and functional decline. The health status classification model for the plateau population is constructed using the method described in claim 1.
