摘要
目的掌握江门市孕妇碘营养状况。方法2018-2023年,采用多阶段分层随机抽样方法,在江门市7个县(市、区)开展孕妇碘营养状况调查。每个县(市、区)按照东、西、南、北、中方位划分5个抽样片区,每个片区抽取1个镇(街),每个镇(街)选取20名孕妇,每年共选取700名孕妇,检测其尿碘、盐碘含量;并调查孕妇2023年补碘情况。结果共检测尿样4200份,尿碘中位数为158.50μg/L,6年间孕妇尿碘中位数分别为138.55、161.30、153.20、166.80、166.60、159.00μg/L。共检测盐样4200份,盐碘中位数为24.50 mg/kg,6年间孕妇盐碘中位数范围为23.70~24.90 mg/kg,碘盐覆盖率范围为98.43%(689/700)~99.71%(698/700),合格碘盐食用率范围为96.57%(676/700)~99.14%(694/700)。食用合格碘盐、不合格碘盐、非碘盐孕妇尿碘中位数(158.70、138.00、89.95μg/L)比较,差异有统计学意义(H=8.18,P=0.017)。2023年孕妇补碘率为99.57%(697/700)。结论江门市孕妇总体碘营养在2018年处于缺乏水平(<150μg/L),2019-2023年维持适宜水平(150~249μg/L),但碘营养水平在标准下限波动,有碘缺乏风险。
Objective To investigate the iodine nutrition status of pregnant women in Jiangmen City.Methods From 2018 to 2023,a multi-stage stratified random sampling method was adopted to analyze the iodine nutrition status of pregnant women in 7 counties(cities and districts)of Jiangmen City.Each county(city and district)was divide into 5 sampling areas based on east,west,south,north,and center directions.One town(street)was selected from each area,and 20 pregnant women were selected in each town(street).A total of 700 pregnant women were selected each year and their urinary iodine and salt iodine levels were tested;and their iodine supplementation status in 2023 was investigated.Results A total of 4200 urine samples from pregnant women were tested,with a median urinary iodine level of 158.50μg/L.Over the course of 6 years,the median urinary iodine levels of pregnant women were 138.55,161.30,153.20,166.80,166.60,and 159.00μg/L,respectively.A total of 4200 salt samples were tested,with a median salt iodine of 24.50 mg/kg.The median range of salt iodine for pregnant women over 6 years was 23.70-24.90 mg/kg,and the coverage rate of iodized salt ranged from 98.43%(689/700)to 99.71%(689/700).The qualified iodized salt consumption rate ranged from 96.57%(676/700)to 99.14%(694/700).The median urinary iodine levels(158.70,138.00,89.95μg/L)of pregnant women who consumed qualified iodized salt,unqualified iodized salt,and no iodized salt were compared,and the difference was statistically significant(H=8.18,P=0.017).The iodine supplementation rate of pregnant woman was 99.57%(697/700)in 2023.Conclusions The overall iodine nutrition of pregnant women in Jiangmen City is insufficient(<150μg/L)in 2018 and maintained at an appropriate level(150-249μg/L)from 2019 to 2023.However,the iodine nutrition of pregnant women fluctuates within the lower limit of the standard,posing a risk of iodine deficiency.
