Salt iodized-content adjusting method

Abstract

The invention discloses a salt iodized-content adjusting method. In the state of unchanging the iodized salt intaking of the crowd at a local area, the salt iodized-content adjusting method sequentially comprises the following steps of (1) obtaining the urine-iodine median of the crowd at the local area through monitoring; (2) obtaining the 24-hour urine amount of the crowd at the local area through monitoring, and obtaining the daily iodine-intaking amount of the crowd at the local area by combing the step (1); (3) measuring the at-home salt-iodine content of residents in the crowd at the local area, simultaneously collecting the daily salt amount of the residents, and calculating the supplied iodine content of iodized salt; (4) deducting the supplied iodine content of the iodized salt from the daily iodine-intaking amount of the crowd at the local area to obtain the EIR (Environmental Iodine Resource) average value of the crowd at the local area at the time period, and then judging the iodine nutrient level of the crowd under a condition without eating the iodized salt according to the daily recommended iodine-intaking amount of an international organization; (5) determining the suitable salt iodized content of different crowds by combining EIRs with the daily iodine-intaking amount target value of the crowd at the local area and the salt eating amount of the crowd at the local area. Practical situations can be reflected by results, and the salt iodized-content adjusting method has the advantages of wide application and simplicity in operation.

Description

technical field [0001] The invention relates to the technical field of iodine deficiency disease monitoring, in particular to a method for adjusting the iodine content of table salt measured by environmental iodine sources. Background technique [0002] Iodine is an essential trace element for the human body. Insufficient or excessive intake of iodine may affect the health of the population. Salt iodization to prevent and treat iodine deficiency disorders was first proposed and practiced by the Swiss in the 1920s, and has since been implemented in many countries, enabling these countries to achieve the goal of eliminating iodine deficiency disorders earlier. Salt iodization is the main means to prevent and control the hazards of iodine deficiency in my country. According to the State Council's "Salt Iodization to Eliminate Iodine Deficiency Hazard Management Regulations", my country adds iodine agents such as potassium iodate to the edible salt of residents in non-high iodin...
