Abstract:
Objective:To study the iodine nutritional status of pregnant women in Jiangxi Province, and to provide basis for iodine supplementation scientifically.Methods:In 2019, 100 counties (cities, districts, referred to as counties) of 11 cities in Jiangxi Province were selected by systematic sampling. Each county was divided into five sections according to five directions: east, west, south, north and middle. One township (street) was taken in each section, and 20 pregnant women (balanced early, middle and late pregnancy) were taken from each township (street) to detect their family salt iodine and urinary iodine levels in order to compare the levels of salt iodine and urinary iodine of different cities and the distribution of urinary iodine in different stages of pregnancy.Results:A total of 10 000 edible salt samples were collected from the families of pregnant women, the median of salt iodine was 24.53 mg/kg, the consumption rate of qualified iodized salt was 97.05% (9 705/10 000), and the iodized salt coverage rate was 99.80% (9 980/10 000). There was no significant difference in the iodine content of edible salt of pregnant women in different cities ( H = 3.42, P > 0.05). A total of 10 000 urine samples were collected from pregnant women, the median of urinary iodine was 175.58 μg/L. There was a statistically significant difference in the urinary iodine content of pregnant women in different cities ( H = 28.80, P < 0.01). There was no statistically significant difference in urinary iodine distribution of pregnant women in different stages of pregnancy (χ 2 = 5.73, P > 0.05). Conclusion:The iodine nutritional status of pregnant women in Jiangxi Province is in a suitable state, but the distribution of iodine nutritional status of pregnant women in different regions is uneven, iodine nutritional status of pregnant women in key regions should be paid attention to.
