Analysis on monitoring results of iodized salt in Xinjiang Production and Construction Corps form 2015 to 2019 / 中华地方病学杂志

ABSTRACT

Objective:To understand the iodine content of edible salt in residents of Xinjiang Production and Construction Corps (referred to as Corps), and provide scientific evidence for prevention and treatment of iodine deficiency disorders.Methods:According to the requirements of the "National Iodine Deficiency Disorders Surveillance Program" form 2015 to 2019, in accordance with the principle of random sampling, one regiment from each of the five directions of east, west, south, north and center in the Corps was selected, and four companies were selected from each regiment. Edible salt samples from the homes of 15 residents in each company were collected, and salt iodine content was quantitatively tested and the test results were analyzed.Results:From 2015 to 2019, 21 028 household salt samples were collected, qualified iodized salt were 20 204, non-qualified iodized salt were 712, non-iodized salt were 112, iodized salt coverage rate was 99.47% (20 916/21 028), iodized salt qualified rate was 96.60% (20 204/20 916), qualified iodized salt consumption rate was 96.08% (20 204/21 028). The average salt iodine content was (27.72 ± 4.81) mg/kg. From 2015 to 2019, the iodized salt coverage rates in the whole Corps were all > 95%, and the iodized salt qualified rates and the qualified iodized salt consumption rate were all > 90%. Among the 14 divisions of the Corps, iodized salt coverage rates were all > 95%, except for the 12th and 14th divisions, where the iodized salt qualified rates and qualified iodized salt consumption rates were < 90%, all other divisions were > 90%.Conclusions:Iodized salt coverage rate, iodized salt qualified rate and qualified iodized salt consumption rate have all reached the national standard for eliminating iodine deficiency disorders from 2015 to 2019, however, non-iodized salt exists in some areas, and the qualified iodized salt consumption rate is low. We should strengthen monitoring of iodized salt in key areas and promote health education, consolidate and maintain achievements in eliminating iodine deficiency disorders.
