Description

Technical Field

[0001] The present invention relates to a health promotion device and a health promotion program that provide a health promotion plan by improving the amount of physical activity suitable for a user based on the vascular age indicating the health of blood vessels and further based on a sleep evaluation index related to the sleep state.

Background Art

[0002] Diseases that develop and progress due to lifestyle factors are collectively called "lifestyle diseases." The number of people suffering from lifestyle diseases (such as cancer, hypertension, diabetes, etc.) reaches 18.5 million, which accounts for about 15% of the total Japanese population. Currently, two-thirds of the causes of death among Japanese people are lifestyle diseases ("cancer, heart disease (mainly myocardial infarction), cerebrovascular disease (mainly stroke), hypertension, diabetes, etc.). The total out-of-pocket amount of health insurance is about 42 trillion yen (Ministry of Health, Labour and Welfare, 2020), and it can be estimated that more than 50% of this is due to lifestyle diseases.

[0003] Lifestyle diseases are closely related to the health of blood vessels. It is known statistically that the health of blood vessels rapidly deteriorates (ages) in men over 40 years old and women in their 50s. The blood vessels of a human are estimated to be about 100,000 km long, the number of cells is estimated to be 30 to 50 trillion, and the flow rate is about 7 tons per day. Since blood vessels supply the necessary components to all cells, the management of the health of blood vessels is a basic requirement for health. The health of blood vessels can be managed as the vascular age. Patent Document 1 discloses a technique for calculating the vascular age using information on the blood vessels in the vertical direction of the retina.

[0004] Sleep is said to be a barometer of health, and we often experience in our daily lives that if we get a good night's sleep and wake up feeling refreshed, we feel invigorated and healthy. On the other hand, in cases of insomnia or a tendency towards insomnia, or when sleep is disrupted due to late-night work, the mood after waking up is often not good. In other words, whether consciously or unconsciously, the state of sleep affects the mood and behavior when awake, and in turn determines the quality of daytime activities after waking up. Thus, sleep is an important factor that has a significant impact on human physical and mental activity, and it can be said that getting good sleep guarantees physically and mentally healthy daily activities.

[0005] Sleep is said to reflect the state of daily life, and good sleep activates the production of vascular repair substances (nitric oxide), enhances immune substances, increases growth hormone, and increases vitality. However, since physical fatigue and psychological tension differ from person to person, it has been considered difficult to predict sleep quality. For this reason, medical treatment for insomnia mainly involves administering sleep-inducing drugs. For example, Patent Document 2 proposes technologies related to various sleep-inducing drugs. Furthermore, attempts have been made to control the ambient temperature during sleep in order to ensure comfortable sleep. Technologies that embody such attempts include, for example, those described in Patent Documents 3 to 5, which determine sleep depth and sleep state based on biological signals and control the ambient temperature of the sleep environment according to the determined sleep depth and sleep state. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2014-23683 [Patent Document 2] Japanese Patent Publication No. 2018-044006 [Patent Document 3] Japanese Patent Publication No. 2008-119454 [Patent Document 4] Japanese Patent Publication No. 2009-247846 [Patent Document 5] Japanese Patent Publication No. 2006-198023 [Overview of the project] [Problems that the invention aims to solve]

[0007] Human health is classified into three categories: healthy, pre-disease, and diseased. The pre-disease state is considered a precursor to lifestyle-related diseases, and preventing both pre-disease and lifestyle-related diseases is extremely important for health. However, vascular aging (hardening) begins in the 50s, and vascular age often exceeds chronological age. Furthermore, it is estimated that approximately 20% of the population suffers from insomnia or a tendency towards insomnia, and this figure rises to approximately 35% among the elderly, with the majority of those prone to insomnia falling into the pre-disease category.

[0008] Sleep and vascular age are closely related to each individual's exercise and activity levels. It is desirable to set target indicators for these factors, control them through exercise, and take measures to prevent and address pre-disease and lifestyle-related diseases. However, current measures against lifestyle-related diseases mostly involve abstract statements such as eliminating smoking and excessive alcohol consumption while maintaining a proper diet, exercise, and sleep, and there are no specific indicators.

[0009] This invention has been made in view of the above circumstances, and aims to provide a health promotion device and health promotion program that provide health promotion suggestions tailored to the user based on vascular age, which indicates the health of blood vessels, and sleep evaluation indicators related to sleep state, with a simple and low-cost configuration. [Means for solving the problem]

[0010] In promoting health, vascular age, which indicates the health of blood vessels, is an important factor. Vascular age is closely related to the amount of physical activity; it worsens when physical activity (especially exercise) decreases and improves when physical activity (especially exercise) increases. In other words, improving exercise habits leads to an improvement in vascular age, so vascular age serves as an indicator of physical activity. The inventors have already proposed a health promotion device and method that can propose health promotion plans from the perspective of vascular health in a patent application, Japanese Patent Application No. 2023-195854. This health promotion device and method proposes a health promotion plan through lifestyle improvements (especially improvements in physical activity) that uses the current vascular health index as the target vascular health index. The vascular health index is calculated based on vascular age using an accelerated pulse wave (APG) waveform created from a pulse wave signal. The pulse wave signal is measured when the user goes to bed, and the vascular health index is output as the result of the cumulative activity amount for the day. The above vascular health index can be used directly from vascular age.

[0011] The inventors diligently pursued further research to find an even simpler and more convenient method. As a result, they arrived at the idea that it would be possible to propose health promotion plans based on vascular age by utilizing the maximum blood pressure value (systolic blood pressure). Maximum blood pressure can be measured using widely available, known home blood pressure monitors or the blood pressure monitoring function of smartwatch-type wearable devices, eliminating the need for special measuring equipment. For example, users can simply measure their maximum blood pressure with a wearable device after exercise and check health promotion plans based on vascular age in real time.

[0012] Therefore, the inventors confirmed the validity of this idea by conducting the following experiment. First, the inventors conducted an experiment in which they measured the systolic and diastolic blood pressure values ​​and vascular age in several subjects of different ages (Experiment 1). All subjects were male, and multiple measurements were taken for each subject.

[0013] Blood pressure values ​​were measured using a blood pressure pulse wave analyzer that involves inserting a fingertip into the sensor. Vascular age was calculated based on the acceleration pulse wave waveform created from the pulse wave signal (fingertip volume pulse wave (DPG)) measured using the same blood pressure pulse wave analyzer. According to Hitoshi Ishiyama et al.: Research on the Analysis of Pulse Wave Data by Wireless Transmission, IEICE Tokyo Chapter Student Meeting Research Presentation 2015, and Haruko Takada et al.: Acceleration Pulse Wave and Vascular Age, Educational Medicine 1998, 44:353-359, the acceleration pulse wave waveform is obtained by mathematically taking the second derivative of the fingertip volume pulse wave waveform, and mathematically, it can be said to be a wave that shows the rate of change of the speed at which the cross-sectional area or volume of the blood vessel increases. By differentiating the fingertip volume pulse wave, the acceleration pulse wave waveform has a stable baseline and is an easily identifiable waveform. The standard waveform of an acceleration pulse wave, as shown in Figure 1, has five distinct elemental waves with peaks a-e. Unlike fingertip volume pulse waves, these elemental waves are systolic waves. Peak a of the elemental waves coincides with the initial rising point of the systolic wave in the fingertip volume pulse wave, peak e corresponds to the start of the diastolic wave in the fingertip volume pulse wave, and the time from peak a to peak e corresponds to the length of the cardiac contraction time.

[0014] It is known that the shape of the acceleration pulse wave waveform recorded at rest differs distinctly with age. Generally, the standard waveform in younger individuals has a deep peak b and a shallow peak d, but as the arteries age, peak b becomes shallower and peak d becomes deeper. In other words, the b / a value increases and the d / a value decreases with age. This property of the waveform is the most important aspect of acceleration pulse wave analysis as a new indicator of vascular health.

[0015] Specifically, to calculate vascular age, peaks a to e are extracted from the second derivative of photoplethysmogram (SDPTG), which is obtained by taking the second derivative of the fingertip volume pulse wave. The SDPTG aging index (SDPTGAI = (bcde) / a) is then calculated using these components. Vascular age is then calculated using this SDPTGAI as 43.47 × SDPTGAI + 65.86 for men and 41.67 × SDPTGAI + 61.75 for women.

[0016] Figures 2 and 3 show the results of Experiment 1. Figure 2 shows the relationship between systolic blood pressure and vascular age, while Figure 3 shows the relationship between diastolic blood pressure and vascular age. As shown in Figure 2, the correlation between systolic blood pressure and vascular age was r=0.82, indicating a high correlation. On the other hand, as shown in Figure 3, no correlation was observed between diastolic blood pressure and vascular age. In other words, it was confirmed that systolic blood pressure is an indicator of vascular age.

[0017] Furthermore, the inventors focused on the fact that mean blood pressure represents the degree of aging of small blood vessels (vascular age), and pulse pressure represents the degree of aging of large blood vessels (vascular age). To confirm whether systolic blood pressure can function as an indicator of the degree of aging of small and large blood vessels (vascular age), they conducted an experiment (Experiment 2) with multiple subjects, measuring systolic blood pressure, pulse pressure, and mean blood pressure. All subjects were male, and multiple measurements were taken for each subject. The mean blood pressure is calculated as mean blood pressure = diastolic blood pressure + (systolic blood pressure - diastolic blood pressure) / 3. The pulse pressure is calculated as pulse pressure = maximum blood pressure - minimum blood pressure. It is known that systolic blood pressure, mean blood pressure, and pulse pressure have a high degree of cross-correlation. The relationship between the degree of vascular aging and mean blood pressure and pulse pressure is described in the book "Blood Pressure Revolution" (Publisher: Kodansha, Author: Kenji Takazawa, Publication Date: July 21, 2005).

[0018] Figures 4 and 5 show the results of Experiment 2. Figure 4 shows the relationship between the maximum blood pressure value and the average blood pressure value, and Figure 5 shows the relationship between the maximum blood pressure value and the pulse pressure value. As a result, as shown in Figure 4, the correlation coefficient r between the maximum blood pressure value and the average blood pressure value was 0.83, indicating a high correlation. Also, as shown in Figure 5, the correlation coefficient r between the maximum blood pressure value and the pulse pressure value was 0.73, indicating a high correlation. That is, it was confirmed that the maximum blood pressure value can be used as an index for the degree of aging (vascular age) of both thin and thick blood vessels.

[0019] Therefore, the health promotion device of the present invention is a health promotion device that provides a health promotion plan by improving the amount of physical activity suitable for the user, comprising a maximum blood pressure value receiving means for receiving the maximum blood pressure value of the user, a vascular age calculating means for calculating the vascular age corresponding to the maximum blood pressure value received by the maximum blood pressure value receiving means based on the correlation between the maximum blood pressure value and the vascular age, and a health promotion plan proposing means for proposing a health promotion plan by improving the amount of physical activity such that the vascular age calculated by the vascular age calculating means is below a predetermined age.

[0020] Further, the health promotion program according to the present invention is characterized in that a computer functions as the above-described health promotion device.

[0021] Such a health promotion device and health promotion program according to the present invention propose a health promotion plan such that the vascular age corresponding to the maximum blood pressure value at that time is below a predetermined age based on the correlation between the maximum blood pressure value and the vascular age.

[0022] In addition, the inventors of the present application have previously proposed a health promotion device that constructs a sleep evaluation prediction model formula unique to a user based on the user's daytime living conditions and performance data of sleep evaluation indicators in Japanese Patent Application No. 2020-161474 and Japanese Patent Application No. 2023-195854, and improves the daytime lifestyle. In these patent applications, the inventors of the present application have clarified that there is a high correlation between the sleep evaluation index (SVP) based on biological signals and the energy value of the autonomic nerve component (very low frequency component (VLF)) obtained from the pulse wave signal (heartbeat signal).

[0023] Here, the sleep evaluation index (SVP) based on biological signals is calculated based on the time ratio of sleep stages (wakefulness, REM sleep, light sleep, deep sleep) according to the international sleep depth determination criteria using a so-called sleep polysomnogram (PSG). Specifically, when the weighting coefficients are α = 20, β = 8, and γ = 1, the sleep evaluation index (SVP) based on biological signals is obtained as sleep evaluation index (SVP) = twenty × deep sleep time + six × light sleep time + REM sleep time. The biological signals are detected non-invasively and without restraint. The determination of the sleep stage based on the detected biological signals adopts, for example, the methods described in Japanese Patent Laid-Open No. 2016-022276, Japanese Patent Laid-Open No. 2016-202463, Japanese Patent Laid-Open No. 2018-029772, etc. by the present applicant, and determines the type of sleep stage (wakefulness stage, REM sleep stage, light sleep stage, and deep sleep stage) of the user during sleep. In addition, the energy value of the very low frequency component (VLF) is measured by a pulse wave meter for the pulse wave (heartbeat signal) before falling asleep, and the energy value of the very low frequency component (VLF) of 0.003 to 0.04 Hz is obtained from the analysis thereof.

[0024] Figure 6 shows the relationship between the energy value of very low frequency components (VLF) and the sleep evaluation index (SVP) based on biosignals. For one subject, the measurement results of autonomic nervous system components (very low frequency components (VLF)) obtained from pulse wave signals and the sleep evaluation index (SVP) based on biosignals were measured for 15 days, and the cross-correlation coefficient was calculated (Experiment 3). As a result, the energy value of very low frequency components (VLF) and the sleep evaluation index (SVP) based on biosignals showed a high correlation of r = 0.7 or higher. In other words, good sleep is obtained when the energy value of very low frequency components (VLF) is high before going to bed.

[0025] Furthermore, the energy value of very low frequency components (VLF) increases with the amount of sustained physical activity. Since the amount of sustained physical activity varies depending on the type and method of exercise, the energy value of very low frequency components (VLF) can serve as an improvement indicator for finding exercise that is suitable for each individual user.

[0026] Furthermore, while the quality of sleep is determined by physical and psychological factors, the energy value of very low frequency components (VLF) is similar. Since very low frequency components (VLF) are closely related to the amount of physical activity during the day (especially exercise), when psychological factors remain constant, adjusting the amount of physical activity (especially exercise) can control very low frequency components (VLF) and improve sleep.

[0027] The inventors diligently pursued the development of a health promotion device that is even simpler, less expensive, and more convenient. As a result, they came to the conclusion that a health promotion device could also be realized using average pulse rate (MPR) and a subjective sleep evaluation index (VAS). Average pulse rate (MPR) can be measured using known home pulse wave meters or the pulse wave measurement function of wristwatch-type wearable devices, and a subjective sleep evaluation index (VAS) can be measured by user input. Neither requires any special measuring equipment and can be measured easily, making it extremely effective in that it places minimal burden on the user.

[0028] Therefore, the inventors confirmed the validity of this idea by conducting the following experiment. First, they conducted an experiment similar to Experiment 3 above with 20 subjects (Experiment 4). As a result, in all subjects, the cross-correlation coefficient between the energy value of very low frequency components (VLF) and the sleep evaluation index based on biological signals (SVP) was r = 0.7 or higher.

[0029] Furthermore, the inventors of the present invention measured the energy value of very low frequency components (VLF) and the mean pulse rate (MPR) for a certain subject for 15 days (Experiment 5). Figure 7 shows the results of Experiment 5. The correlation coefficient between the energy value of very low frequency components (VLF) and the mean pulse rate (MPR) was r = 0.9 or higher, indicating a clear correlation.

[0030] Furthermore, the inventors of the present invention measured the average pulse rate (MPR) before sleep and the subjective sleep evaluation index (VAS) after sleep for approximately 15 days for a certain subject (Experiment 6). The subjective sleep evaluation index (VAS) was measured using a visual analog scale method ranging from 100% (good sleep) to 0% (poor sleep), based on the subject's self-report. Figure 8 is a table showing the results of Experiment 6. In Figure 8, values ​​in the range where the average pulse rate (MPR) was 60 or less and the sleep evaluation index (VAS) was 60% or less were excluded as outliers. As a result, the cross-correlation coefficient between the average pulse rate (MPR) and the subjective sleep evaluation index (VAS) was r = 0.8 or higher, indicating a clear correlation.

[0031] Based on the above, the inventors confirmed that it is possible to propose health promotion measures by using the correlation between mean pulse rate (MPR) and a subjective sleep evaluation index (VAS) instead of the correlation between very low frequency components (VLF) and a sleep evaluation index based on biological signals (SVP).

[0032] Therefore, the health promotion device according to the present invention, which achieves the above-mentioned objective, is based on the above-mentioned health promotion device that uses the systolic blood pressure value and vascular age, An average pulse rate receiving means for receiving the average pulse rate of the user, A sleep evaluation index receiving means that receives sleep evaluation indices, which are subjective evaluations of the user's sleep, A storage and recording means for storing and recording the average pulse rate before sleep received by the average pulse rate receiving means and the sleep evaluation index after sleep received by the sleep evaluation index receiving means, The system includes a correlation calculation means for calculating the correlation between the average pulse rate stored and recorded by the storage and recording means and a sleep evaluation index, The health promotion proposal means is characterized by proposing a health promotion plan that improves the amount of physical activity, based on the correlation between the average pulse rate calculated by the correlation calculation means and the sleep evaluation index, so that the average pulse rate received by the average pulse rate receiving means is set to a predetermined value or less.

[0033] Furthermore, the health promotion program according to the present invention is characterized by using a computer as the health promotion device.

[0034] The health promotion device and health promotion program according to the present invention propose a health promotion plan that reduces the average pulse rate (MPR) to a predetermined value or lower, based on the correlation between the average pulse rate (MPR) and a subjective sleep evaluation index (SVP). [Effects of the Invention]

[0035] In this invention, a health promotion plan can be provided that improves the amount of physical activity tailored to the user, using a simple and low-cost configuration. [Brief explanation of the drawing]

[Figure 18] This diagram illustrates the health promotion method of the above embodiment as a flowchart. [Modes for carrying out the invention]

[0037] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

[0038] (First Embodiment) A first embodiment of the present invention is a health promotion device 1 that provides health promotion suggestions tailored to the user based on vascular age, particularly through improvements in physical activity levels (physical activity levels include exercise). Figure 9 is a diagram showing the configuration of the health promotion device 1 as blocks. The health promotion device 1 is mounted on a wearable terminal 100. The health promotion device 1 may be configured as a cloud server or the like, or as a separate personal computer or the like.

[0039] The wearable terminal 100 is preferably a wristwatch-type device such as a smartwatch, and is equipped with functions for executing computer programs using hardware such as a CPU and memory, functions for sending and receiving data via a network, and input / output functions for inputting or outputting data. The wearable terminal 100 is also equipped with a measuring device M capable of measuring the user's average pulse rate. In addition to the user's average pulse rate, the measuring device M may also be equipped with functions for measuring biosignals and physical activity levels such as blood pressure, steps taken, distance traveled, calories burned, and METs values.

[0040] The health promotion device 1 comprises a systolic blood pressure reception unit 11, a vascular age calculation unit 12, and a health promotion suggestion unit 15. These units 11, 12, and 15 can be implemented, for example, as programs executable using hardware such as a CPU (Central Processing Unit) and memory in a computer that performs signal processing, or using a dedicated processor such as a DSP (Digital Processing Unit) mounted on an expansion board that can be attached to a computer. In other words, this program or processor enables the computer (wearable terminal 100) to function as the health promotion device 1.

[0041] The systolic blood pressure reception unit 11 receives the systolic blood pressure value. The systolic blood pressure value is measured by the blood pressure monitor function and pulse wave meter function of the measuring instrument M and supplied to the health promotion device 1. The systolic blood pressure value received by the systolic blood pressure reception unit 11 is supplied to the vascular age calculation unit 12.

[0042] The vascular age calculation unit 12 calculates the vascular age corresponding to the systolic blood pressure value received by the systolic blood pressure value reception unit 11, based on the correlation between the systolic blood pressure value and vascular age. Since the correlation between systolic blood pressure value and vascular age is characteristic for each gender, it can be generalized for each gender. For this reason, the correlation between systolic blood pressure value and vascular age is stored in a memory unit (not shown) as a predetermined correlation formula or correlation table for each gender. In this way, the vascular age calculation unit 12 calculates the vascular age at that time using the correlation formula or correlation table stored in the memory unit. The vascular age calculated by the vascular age calculation unit 12 is supplied to the health promotion proposal unit 15.

[0043] The health promotion proposal unit 15 proposes a health promotion plan that improves physical activity levels so that the vascular age calculated by the vascular age calculation unit 12 falls below a predetermined age. The health promotion device 1 outputs the health promotion plan and either displays it on the screen of the wearable terminal 100, prints it using a separate printing device, or stores it as data in a storage device.

[0044] For example, the health promotion proposal unit 15 proposes a health promotion plan such that the vascular age calculated by the vascular age calculation unit 12 is less than or equal to a target vascular age selected based on the user's age. The target vascular age is preferably a vascular age that is achievable for the user (for example, an age 10 years younger than the user's actual age). In this case, when the user inputs the target vascular age into the wearable terminal 100, it is supplied to the health promotion proposal unit 15. If the input value is the actual age, the health promotion proposal unit 15 calculates an age that is a predetermined number of years (for example, 10 years) lower than the input value and sets it as the target vascular age.

[0045] The health promotion suggestion unit 15 may include the current vascular age calculated by the vascular age calculation unit 12 in the health promotion suggestion. The health promotion suggestion unit 15 may also output the target vascular age in the health promotion suggestion. The health promotion suggestion unit 15 may also include the amount of physical activity for that day in the health promotion suggestion. The amount of physical activity may be expressed in METs, or in terms of the type and duration of exercise that achieves that amount of physical activity. The health promotion suggestion unit 15 may also propose a health promotion suggestion if the difference between the current vascular age and the target vascular age is greater than or equal to a predetermined value. The health promotion suggestion unit 15 may also include the systolic blood pressure value in the health promotion suggestion. In this way, the health promotion device 1 proposes a health promotion suggestion to the user that relates to physical activity that will improve the current vascular age.

[0046] Furthermore, the health promotion plan may also be arranged in chronological order, as shown in the improvement examples described later, with the time of measurement of the systolic blood pressure value and the vascular age at that time, as well as the time and amount of physical activity. In this case, the health promotion plan is preferably output in tabular format.

[0047] Regarding the amount of physical activity, data entered by the user into the wearable terminal 100 (activity time, activity content, and other information related to physical activity) may be used, or data such as steps, distance traveled, calories burned, and METs values ​​measured by various sensors included in the measuring device M may be used. "METs" is a unit that represents how many times stronger physical activity is compared to resting. Sitting at rest is 1 MET, and normal walking is equivalent to 3 METs. The amount of activity is expressed as "exercise (Ex)" (= METs-hour) (unit of quantity) by multiplying the intensity of physical activity (METs) by the duration of the physical activity (hours). Therefore, the more intense the physical activity, the shorter the time it takes to reach 1 exercise. The Ministry of Health, Labour and Welfare has established a METs intensity table according to the content of exercise in the "Exercise Standards for Health Promotion 2006". For example, the following standards are set for physical activity and activity levels for promoting health: "Physical activity level: 23 METs-hours / week" (approximately 60 minutes per day of activity with an intensity of 3 METs or higher; equivalent to approximately 8,000 to 10,000 steps per day if the activity is primarily walking), and "Activity level: 4 METs-hours / week" (for example, approximately 60 minutes of brisk walking, or approximately 35 minutes per week of jogging or playing tennis).

[0048] (Operation instructions) The following describes the health promotion method realized by the health promotion device 1. Figure 10 is a flowchart illustrating the health promotion method of this embodiment. When using this health promotion device 1, the user measures their systolic blood pressure using the blood pressure monitor function of the measuring instrument M mounted on the wearable terminal 100. The timing of measuring systolic blood pressure is not limited to before sleep and can be arbitrary, but after exercise, it should be done after cooling down or after a certain period of time has passed, when the body has settled down.

[0049] The health promotion device 1 receives the systolic blood pressure value via the systolic blood pressure value receiving unit 11 (systolic blood pressure value receiving process S11). The systolic blood pressure value is obtained from the measuring instrument M. The received systolic blood pressure value is supplied to the vascular age calculation unit 12.

[0050] The vascular age calculation unit 12 calculates the vascular age corresponding to the systolic blood pressure value received in the systolic blood pressure value reception step S11, based on the correlation between vascular age and systolic blood pressure value (vascular age calculation step S12). The calculated vascular age is supplied to the health promotion proposal unit 15.

[0051] The health promotion proposal unit 15 proposes a health promotion plan through improved physical activity levels so that the vascular age calculated in the vascular age calculation process S12 is improved to a predetermined age or lower (health promotion proposal process S13).

[0052] For example, if the health promotion plan includes vascular age and physical activity level, the user can reflect on their own activity level based on their vascular age and physical activity level, and identify and implement physical activity levels that will improve their vascular age. Also, if the health promotion plan includes the current vascular age, the user can quantitatively understand their physical activity level based on that vascular age and improve their physical activity level. Furthermore, if the health promotion plan includes the current vascular age and target vascular age, the user can easily check their current level of achievement by comparing their current vascular age with their target vascular age. In this case, the user sets their target vascular age in the wearable terminal 100 in advance. When the health promotion plan proposal unit 15 acquires physical activity level from data entered into the wearable terminal 100, the user appropriately enters the physical activity level (record of physical activity) into the wearable terminal 100 and stores it in the memory unit. Also, when the health promotion plan proposal unit 15 acquires physical activity level from accumulated data of various sensors included in the measuring instrument M, the user stores the various data from the measuring instrument M in the memory unit. Thus, users gain concrete goals for improving their physical activity levels from the perspective of vascular health, which increases their motivation to improve their physical activity levels (especially exercise). Furthermore, since there is a high correlation between systolic blood pressure and pulse pressure, managing vascular age is also effective from the perspective of blood pressure management.

[0053] Furthermore, the timing of the output of health promotion suggestions is not limited to before sleep, but can be at any time. For example, if the systolic blood pressure is measured after exercise, the output of health promotion suggestions will reflect the cumulative activity level (especially the amount of exercise) up to that point. If the systolic blood pressure is measured before sleep (before going to bed), the cumulative activity level up to before sleep will be reflected.

[0054] Here's an example of how to effectively use Health Promotion Device 1: First, the user measures their systolic blood pressure before exercise and uses Health Promotion Device 1 to determine their vascular age before exercise. Then, the user performs physical activity (exercise) for a predetermined time. This physical activity should be appropriate for the individual (e.g., warm-up exercises, strength training, running), and a certain amount of aerobic exercise (e.g., 20-50 minutes) is effective. For aerobic exercise, the desired heart rate (pulse rate) range (fat burn zone) is 40-60% of the maximum heart rate (maximum heart rate = 220 - age). After that, the user measures their systolic blood pressure and uses Health Promotion Device 1 to determine their vascular age after exercise. By comparing their vascular age before and after exercise, and by reviewing their physical activity level, the user can confirm the effects of their exercise. They can also compare their post-exercise vascular age with their target vascular age and revise their physical activity level accordingly. It is preferable to set the target vascular age 5 to 10 years lower than the actual age and gradually lower it while confirming the effects of exercise. If the vascular age after exercise does not reach the target vascular age, the user should conclude that their physical activity level is insufficient and increase their physical activity level (e.g., exercise time) in the next exercise session. Furthermore, for accuracy, it is important that the user remains at rest and has a low pulse rate when measuring blood pressure. Also, if the physical activity is aerobic exercise, it is preferable to measure blood pressure 5 hours after the exercise. However, since the blood pressure-lowering effect of aerobic exercise depends on the duration of the exercise, the timing of blood pressure measurement should be adjusted as appropriate.

[0055] The following describes an example of improving physical activity using the health promotion device 1. The inventors used a 75-year-old male as a subject and output data such as date and time, vascular age, systolic blood pressure, diastolic blood pressure, steps per day, calories burned, and activity record as part of a health promotion plan. The systolic blood pressure, diastolic blood pressure, steps per day, and calories burned were recorded using stored data measured by the measuring device M of the wearable terminal 100 (a wristwatch-type mobile terminal). The activity record was recorded using data stored in the wearable terminal 100 based on input from the subject. The activity record consisted of exercise content (type and duration of exercise). The target vascular age was set at 65.

[0056] Figures 11 to 16 show the results. Figures 11 and 12 show health promotion plans using non-aerobic exercise, while Figures 13 to 16 show health promotion plans using aerobic exercise. Fat burning becomes efficient after about 20 minutes of aerobic exercise. In addition to fat burning, aerobic exercise is effective in improving vascular age through vascular stimulation. The effects of exercise at each time point were confirmed by comparing vascular age and systolic blood pressure values ​​before and after exercise. Furthermore, the effects of cumulative exercise volume over a day were confirmed by comparing vascular age and systolic blood pressure values ​​at the time of waking and going to bed.

[0057] As shown in Figures 11 and 12, non-aerobic strength training did not reach the target vascular age (vascular age 65), and it was found that the improvement effect on both vascular age and blood pressure was low. In contrast, as shown in Figures 13 to 16, when the amount of aerobic exercise was relatively large (approximately 30 to 40 minutes of running), the target vascular age (vascular age 65) was often reached or below, and the improvement effect on both predicted vascular age and blood pressure was high. When the amount of aerobic exercise was relatively small (approximately 10 to 16 minutes of running), the improvement effect on both vascular age and blood pressure was low. Furthermore, when the cumulative amount of aerobic exercise per day was large (approximately 46 to 60 minutes of running in total), the improvement effect on predicted vascular age (vascular age calculated by the vascular age calculation unit 12 of the health promotion device 1) and blood pressure at bedtime (before sleep and after bathing) was large.

[0058] In other words, the health promotion plan shown in Figures 11 to 16 indicates that for this subject, running for 30 to 40 minutes of aerobic exercise is more effective than strength training with non-aerobic exercise. This allows the subject to improve their physical activity level (especially the amount of exercise) in a way that suits them. Thus, it is preferable that the health promotion plan includes the subject's current vascular age and physical activity level (exercise content), as well as the vascular age and physical activity level (exercise content) that meet the target. Here, it is important that this improvement in physical activity level (especially the amount of exercise) is continued. Although the improvement effect of exercise is temporary, by repeatedly continuing such improvements in physical activity level, permanent improvement can be expected. If the only data available to the subject is blood pressure, the subject may aim for a blood pressure value that is generally considered desirable. For example, a target blood pressure value of 130 or less systolic blood pressure is said to reduce the incidence of vascular disorders (such as cerebral infarction and myocardial infarction). However, it is difficult to concretely imagine one's own health condition and the necessary exercise content from blood pressure values ​​alone, making it difficult to maintain motivation for exercise. In contrast, in this improved case, subjects can confirm the degree of aging of their own blood vessels based on the outputted vascular age, and can easily visualize the type of exercise needed to improve their vascular age. In other words, in this improved case, subjects can more easily visualize improvements in their vascular health and physical activity levels, which is expected to maintain and further increase their motivation to exercise.

[0059] (Second Embodiment) The health promotion device 2 includes, in addition to the functions of the health promotion device 1 of the above embodiment, an average pulse rate receiving unit 21, a sleep evaluation index receiving unit 22, a storage and recording unit 23, a correlation calculation unit 24, and a health promotion suggestion unit 25. These units 21-25 can be implemented, for example, as programs executable using hardware such as a CPU (Central Processing Unit) and memory in a computer that performs signal processing, or as dedicated processors such as a DSP (Digital Processing Unit) mounted on an expansion board that can be attached to a computer. In other words, this program or processor enables the computer (wearable terminal 100) to function as the health promotion device 2. Note that components identical to those in the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

[0060] The average pulse rate reception unit 21 receives input of the user's average pulse rate (MPR). The average pulse rate is the average value of the pulse rate recorded per minute, and is measured, for example, using the pulse rate measurement function or pulse wave meter function of the measuring instrument M, and supplied to the health promotion device 2. The average pulse rate received by the average pulse rate reception unit 21 is supplied to the storage and recording unit 23 or the health promotion plan proposal unit 25. The destination of the average pulse rate is the storage and recording unit 23 when the average pulse rate data is stored and stored as preparation, and then to the health promotion plan proposal unit 25 when the health promotion plan proposal processing is executed. The destination may be selected by the user through mode switching or other operations.

[0061] The sleep evaluation index receiving unit 22 receives the sleep evaluation index (VAS), which is a subjective evaluation of the user's sleep. The sleep evaluation index (VAS) is input by the user into the wearable terminal 100, received by the sleep evaluation index receiving unit 22, and supplied to the storage and recording unit 23.

[0062] The sleep evaluation index (VAS) received by the sleep evaluation index receiving unit 22 is preferably based on the Visual Analogue Scale method. The Visual Analogue Scale is a method primarily used to quantitatively evaluate a patient's subjective symptoms and is also called a visual evaluation scale. In this embodiment, this Visual Analogue Scale is used as a scale to represent the user's satisfaction with the quality of their sleep. For example, the user expresses their satisfaction with their sleep at the time of waking on a scale from 0% (poor sleep) to 100% (good sleep), and inputs this value as the sleep evaluation index (VAS).

[0063] The storage and recording unit 23 stores and records the average pulse rate (MPR) before sleep, received by the average pulse rate receiving unit 21, and the visual arithmetic score (VAS) after sleep, received by the sleep evaluation score receiving unit 22. The average pulse rate (MPR) and sleep evaluation score (VAS) before and after sleep are stored in a memory unit (not shown) in association with each other. This set of average pulse rate and sleep evaluation score is collected over a certain period (for example, 15 days).

[0064] The correlation calculation unit 24 calculates the correlation between the average pulse rate (MPR) and the visual arithmetic score (VAS) stored and recorded by the storage and recording unit 23. This correlation can be constructed as a correlation formula or a correlation table.

[0065] When the correlation is expressed by a correlation formula, the correlation calculation unit 24 constructs a correlation formula representing the correlation between average pulse rate (MPR) and sleep evaluation index (VAS) from the data of average pulse rate (MPR) and sleep evaluation index (VAS) accumulated and recorded by the accumulation recording unit 23. Using the accumulated data shown in Figure 8 as an example, the correlation formula is y = -1.9977x + 188.08 (Equation 1). Here, y is the sleep evaluation index (VAS) after sleep, and x is the average pulse rate (MPR) before sleep. When the lower limit of the good sleep evaluation index (VAS) selected by the user is 50%, the corresponding average pulse rate (MPR) is approximately 69. Therefore, the user will get good sleep if their average pulse rate is 69 or less. However, since 50% is the limit value for the sleep evaluation index, 60% or more is preferable from the viewpoint of sufficiently good sleep quality. Needless to say, this correlation will differ depending on the user.

[0066] The health promotion proposal unit 25 proposes a health promotion plan based on the correlation calculated by the correlation calculation unit 24, which then proposes a plan for improving lifestyle, particularly physical activity levels, that will reduce the average pulse rate (MPR) received by the average pulse rate reception unit 21 to below a predetermined value.

[0067] For example, the health promotion proposal unit 25 may, based on the correlation calculated by the correlation calculation unit 24, propose a health promotion plan that improves the amount of physical activity so that the average pulse rate received by the average pulse rate reception unit 21 is less than or equal to the target average pulse rate corresponding to the target sleep evaluation index. In this case, it is preferable that the health promotion proposal unit 25 includes the average pulse rate at that time and the target average pulse rate in the health promotion plan. The target sleep evaluation index may be stored in a memory unit (not shown) as a predetermined value (e.g., 60%), or it may be set arbitrarily by the user by inputting it into the wearable terminal 100. Furthermore, the target average pulse rate corresponding to the target sleep evaluation index may be calculated based on the correlation calculated by the correlation calculation unit 24.

[0068] Furthermore, for example, the health promotion proposal unit 25 may calculate a predicted sleep evaluation index corresponding to the average pulse rate received by the average pulse rate reception unit 21, based on the correlation between the average pulse rate calculated by the correlation calculation unit 24 and the sleep evaluation index, and propose a health promotion plan that improves physical activity so that this predicted sleep evaluation index is equal to or greater than the target sleep evaluation index. In this case, it is preferable for the health promotion proposal unit 25 to include the predicted sleep evaluation index in the health promotion plan. The amount of physical activity is the same as in the above embodiment.

[0069] Furthermore, for example, the health promotion proposal unit 25 may include the current physical activity level and the target physical activity level in the health promotion proposal. The physical activity level may be expressed in METs, or it may be expressed in terms of the type and duration of exercise that achieves that level of physical activity. In addition, the health promotion proposal unit 25 may propose a health promotion plan if the sleep evaluation index received by the sleep evaluation index receiving unit 11 differs from the target sleep evaluation index by a certain value or more. Moreover, the health promotion proposal unit 25 also has the functions of the above embodiment, and when the vascular age is supplied from the vascular age calculation unit 12, it proposes a health promotion plan from the perspective of vascular age.

[0070] Furthermore, since the average heart rate can increase dramatically due to emotional states or stress, it is acceptable to propose an activity level as a health promotion plan that takes into account the phenomena that affected the average heart rate, based on records of the user's daily life using methods such as the so-called VAS method, including psychological and physical aspects, so that the average heart rate remains below a predetermined value (below the target average heart rate).

[0071] Furthermore, the health promotion device 2 may also include a data storage mode and a health promotion suggestion mode. In the data storage mode, the average pulse rate received by the average pulse rate receiving unit 21 and the sleep evaluation index received by the sleep evaluation index receiving unit 22 are supplied to the storage recording unit 23. In the health promotion suggestion mode, the average pulse rate received by the average pulse rate receiving unit 21 is supplied to the health promotion suggestion unit 25.

[0072] (Operation instructions) The following describes the health promotion method implemented by the health promotion device 2. This health promotion method is implemented by a processor executing each step. Figure 18 is a flowchart illustrating the health promotion method of this embodiment. When using the health promotion device 2, the user first creates correlation data between average pulse rate and sleep evaluation index by accumulating a set of average pulse rate and sleep evaluation index before and after sleep. For example, the user uses the health promotion device 2 in data accumulation mode and measures the average pulse rate before sleep and the sleep evaluation index after sleep over a certain period (e.g., 15 days). The average pulse rate is measured before sleep (within 1 hour before falling asleep) using the pulse meter function of the measuring instrument M installed in the wearable terminal 100. The sleep evaluation index is measured after sleep by the user inputting a subjective evaluation value into the wearable terminal 100.

[0073] At this time, the user separately records details of their daily life, such as exercise, in conjunction with a set of average heart rate and sleep evaluation indices. For example, exercise details could include the type of exercise, such as stretching or running, and the duration of that exercise. The recorded data for exercise details can be either data entered by the user themselves into the wearable terminal 100, or recorded data such as steps, distance traveled, calories burned, and METs values ​​measured using the measuring instrument M installed in the wearable terminal 100. The health promotion device 2 acquires this recorded data from the storage unit and supplies it to the health promotion proposal unit 25 for use.

[0074] Furthermore, in order to ensure that the correlation data between mean pulse rate (MPR) and visual arithmetic scale (VAS) is ideal and independent of the user's physical ailments or environmental conditions such as the bedroom, it is desirable for users to refrain from measurement if any of the following occurs: 1) if the user experiences physical ailments such as sudden leg cramps or abdominal pain during the night; 2) if the sleep environment deteriorates, such as when the bedding is unsuitable and the user is cold, or when they cannot sleep due to ambient noise; 3) if the user is not sleepy but is idly staying in bed; or 4) if the user becomes emotionally agitated after measuring mean pulse rate, such as after an argument with someone (in this case, mean pulse rate will rise drastically). It is desirable to exclude the user from measurement in these cases. In addition, mean pulse rate should be measured in a stable state approximately 1 to 1.5 hours before going to bed. Since pulse rate will be higher if exercise or bathing has occurred immediately before mean pulse rate measurement, it should be avoided. Furthermore, if there is an arrhythmia, the mean pulse rate will show an abnormal value. In the health promotion device 2, it is preferable to remove such abnormal values ​​and determine the correlation.

[0075] The health promotion device 2 determines whether the input data is the average pulse rate or a sleep evaluation index (determination step S1). If it is the average pulse rate, it proceeds to the average pulse rate reception step S2; if it is a sleep evaluation index, it proceeds to the sleep evaluation index reception step S3. If the input data is the average pulse rate, the health promotion device 2 receives the average pulse rate using the average pulse rate reception unit 21 (average pulse rate reception step S2). The health promotion device 2 determines the mode (mode determination step S4). If the health promotion device 2 is being used in data storage mode, it proceeds to the storage recording step S5; if it is being used in health promotion proposal mode, it proceeds to the health promotion proposal step S7. In this case, the usage is in data storage mode, so the storage recording unit 12 records the average pulse rate (storage recording step S5).

[0076] Furthermore, if the input data in the determination step S1 is a sleep evaluation index, the health promotion device 2 receives the sleep evaluation index via the sleep evaluation index receiving unit 22 (sleep evaluation index receiving step S3). Upon receiving the sleep evaluation index, the health promotion device 2 records the sleep evaluation index via the storage recording unit 12 (storage recording step S5). This process is repeated over a predetermined period (for example, 15 days).

[0077] Once the accumulation and recording of measurement data for a predetermined period is complete, the health promotion device 2 uses the correlation calculation unit 24 to calculate the correlation between the average pulse rate accumulated and recorded in the accumulation and recording step S5 and the sleep evaluation index (correlation calculation step S6).

[0078] After data storage is complete, the user uses the health promotion device 2 in health promotion suggestion mode. The user measures their average pulse rate before sleep (within one hour before falling asleep) using the pulse meter function included in the measuring instrument M installed in the wearable terminal 100. The measured average pulse rate is supplied to the health promotion device 2. The health promotion device 2 receives the average pulse rate via the average pulse rate receiving unit 21 (average pulse rate receiving step S2), performs a mode determination (mode determination step S4), and supplies that average pulse rate to the health promotion suggestion unit 25. Based on the correlation calculated in the correlation calculation step S6, the health promotion suggestion unit 25 outputs a health promotion suggestion by improving physical activity so that the average pulse rate received in the average pulse rate receiving step S2 is below a predetermined value (health promotion suggestion step S7). The health promotion suggestion proposed here is tailored to the user to improve their sleep state. In this way, the health promotion proposal unit 25 presents health promotion proposals that enable good sleep by improving daytime lifestyle, particularly physical activity levels, so that the measured average pulse rate falls below a predetermined value.

[0079] For example, if a health promotion plan includes the average heart rate at that time and the target average heart rate, users can quantitatively understand their physical activity level by comparing these values ​​and improve their physical activity level. Also, if a health promotion plan includes a predicted sleep evaluation index and the amount of physical activity for that day, or a target sleep evaluation index and the amount of physical activity required to achieve it, users can review their daily activities and improve their physical activity level to achieve their target sleep evaluation index. In this way, users gain concrete goals regarding the improvement of their physical activity level, which increases their motivation to improve their physical activity level (especially exercise), and this repeated process leads to continuous improvement in physical activity level.

[0080] For example, a user could measure their average heart rate in the evening and generate a health improvement plan. Based on this plan, the user would then exercise a certain amount of time before going to sleep. This would allow the user to lower their average heart rate and improve their sleep. Furthermore, based on the generated health improvement plan, the user could reflect on their daily lifestyle and improve their health through exercise or meditation for psychological improvement the following day. However, it is important to note that significantly increasing the amount of exercise immediately before going to bed can activate the autonomic nervous system and disrupt sleep.

[0081] Furthermore, since the health promotion device of this embodiment includes the functions of the health promotion device of the first embodiment described above, it is possible to propose health promotion measures not only from the perspective of sleep but also from the perspective of vascular health. Both the sleep evaluation index and vascular age described above worsen when the amount of exercise or activity decreases and improve when the amount of exercise or activity increases. Good sleep is a necessary condition for activating the production of vascular repair substances (nitric oxide). Both the sleep evaluation index and vascular age have related properties in that they lead to poor sleep and elevated blood pressure as the sympathetic nervous system component of the autonomic nervous system becomes continuously dominant due to psychological worries and stress. In the health promotion device of this embodiment, physical activity (especially exercise) is proposed as a health promotion measure to promote improvement of the sleep evaluation index and vascular age. Exercise improves sleep and vascular health, including psychological worries, and stimulates blood vessels by moderately increasing heart rate, thereby restoring vascular flexibility. Also, excessive sleep or rest worsens vascular age. Thus, managing health from both the perspectives of sleep evaluation indicators and vascular age is highly effective for promoting health.

[0082] It should be noted that the present invention is not limited to the embodiments described above. For example, the health promotion devices 1 and 2 may consist of a cloud server connected via a network to a mobile terminal owned by the user. In this case, a computer program that makes the cloud server function as the health promotion devices 1 and 2 is installed on the cloud server and executed. In addition, the average pulse rate, systolic blood pressure, and physical activity level may be measured by a measuring device separate from the health promotion devices 1 and 2.

A health promotion method characterized in that the processor comprises a health promotion proposal step which proposes a health promotion plan by improving the amount of physical activity so that the vascular age calculated in the vascular age calculation step is below a predetermined age.
