Analysis of iodine nutritional status in pregnant women in Luzhou City of Sichuan Province from 2018 to 2022
Objective To explore the iodine nutritional status of pregnant women in Luzhou City from 2018 to 2022,so as to provide a basis for the prevention and control of iodine deficiency disorders.Methods According to the"National Monitoring Plan for Iodine Deficiency Disorders"(2016 edition),a multi-stage stratified cluster random sampling method was used to collect random urine samples from pregnant women and salt samples from their homes,and iodine content was measured.Results A total of 3 500 urine samples and 3 500 salt samples were tested.The median urinary iodine was 155.3 μg/L.In 2019 and 2020,the median urinary iodine of pregnant women was lower than in other years(all P＜0.001).There was no statistically significant difference in median urinary iodine among pregnant women in different age groups(Z=-0.297,P=0.766).The median urinary iodine in early pregnancy was higher than in mid-term and late-term pregnancy(Z=3.195,3.068;P=0.001,0.002).There were significant differences in median urinary iodine among pregnant women in different counties(districts)(H=36.592,P＜0.001).The median salt iodine,iodized salt coverage rate,iodized salt qualification rate and qualified iodized salt consumption rate were 26.6 mg/kg,99.57％,95.58％and 95.71％,respectively.The differences in salt iodine content,iodized salt coverage rate,iodized salt qualification rate and qualified iodized salt consumption rate among different years and counties(districts)were statistically significant(all P＜0.05).Conclusion Overall,the iodine nutritional status of pregnant women in Luzhou City from 2018 to 2022 was suitable,and the consumption of iodized salt was satisfied,meeting the national standards for eliminating iodine deficiency disorders.However,pregnant women still faced the risk of iodine deficiency.In the future,efforts should be continued to monitor iodine nutritional status and strengthen education on rational iodine nutrition during pregnancy.
