Abstract

The invention discloses an iodine nutrition level individualization evaluation method and application. The method comprises the steps that (1) individual salt intake is acquired through a 3-day salt weighing method; (2) the salt iodine content is determined and the step (1) is combined to acquire individual salt iodine intake; (3) individual diet iodine intake is acquired; and (4) the reference intake of iodine diet is compared with the individual diet iodine intake in the step (3) to evaluate the individual iodine level. In the step (3), the individual salt intake and the individual salt iodine intake in the steps (1) and (2) are substituted into the formula individual diet iodine intake=daily salt intake*salt iodine content*(1-salt iodine cooking loss ratio (L)) / proportional coefficient(F), wherein L is 24.6%; F is equal to 0.65 to 0.85, and is acquired from individual salt iodine intake (S) / individual total iodine intake (D); S is acquired similar to the steps (1) and (2); and D isacquired by measuring 24-hour urine iodine repeatedly. The method provided by the invention can be used to calculate and evaluate individual daily iodine level, solves the problem of inadequate individual iodine evaluation methods, has good application and operability, and has a clinic guiding significance.

Description

technical field

[0001] The invention relates to the technical field of iodine nutrition assessment, and relates to assessing the daily dietary iodine intake and iodine nutrition status of individuals by taking the salt intake obtained by a three-day salt weighing method as an entry point. Background technique

[0002] Iodine is one of the essential trace elements for the human body. Only when the human body has sufficient iodine intake can the normal synthesis of thyroid hormones be guaranteed, and then the physiological functions such as promoting intellectual development and physical development can be exerted. Insufficient iodine intake will lead to iodine deficiency disease, the main hazard of iodine deficiency disease is to affect the brain development of infants, cause intellectual and physical developmental disorders, and affect the quality of the people. After more than 20 years of implementation of the universal salt iodization (USI) plan, my country has made great ...

Examples

Embodiment 1

[0049] The application process of the individualized assessment method of iodine nutrition level:

[0050] (1) The determination method of individual salt intake: Individuals or staff of preventive and medical institutions weigh the salt bags / cans before breakfast and after dinner every day, and weigh the salt-added meals for each meal and pour The weight of the leftovers and leftover soup, and the daily consumption of other salty condiments (soy sauce, vinegar, monosodium glutamate, sauce and fermented bean curd), the number of diners and their ages were recorded for a period of 3 days; according to the correction formula: per capita daily Salt consumption = (salt consumption + the amount of NaCl equivalent to salty condiments - salt content in the remaining meals) / total person-days; where: total person-days = ∑ (person-days of each member × standard person coefficient); Number of diner days = total number of breakfast meals × ratio of breakfast meals + total number of lunc...

Embodiment 2

[0056] Taking the family as the unit, 10 households were selected as the survey objects, with a total of 36 family members. Taking adults as an example, there were 20 people in total, with an average age of 34.6±5.9 years. This method and the 24-hour urinary iodine excretion method were used to estimate the individual dietary iodine intake, and the corresponding statistical methods were used to analyze and compare the ability and effect of this method to assess individual iodine intake and individual iodine nutritional status.

[0057] 1. This method:

[0058] (1) The determination method of individual daily salt intake (g / d): Weigh the salt shakers before and after cooking the breakfast and dinner for the 10 families, and weigh the freshly cooked salt for each meal. The weight of salted meals and the weight of leftovers and leftover soup, and the respondents were warned not to eat overnight meals during the survey period; reviewing other salty condiments (soy sauce, vinegar,...

[0070] Comparative test:

[0071] The present invention method and literature report method (Konig F, Andersson M, Hotz K, et al . 2011; Andersen S.O., Karmisholt J., Pedersen K.M. et al . 2008), when evaluating individual iodine nutrition level, it has fewer sampling times, shorter collection period, simple measurement index, strong practicability, and can reflect the recent individual iodine nutrition level, while short-term or real-time individual iodine nutrition Monitoring has guiding significance, which is convenient for people to know and adjust their food intake and iodized salt intake in a timely manner, so as to maintain an appropriate iodine nutrition level, see Table 3.
