摘要
目的了解四川省什邡市孕妇碘营养水平,为孕妇碘缺乏病防治政策的调整提供依据。方法按照《四川省碘缺乏病监测方案(2013年修订)》及《四川省重点人群碘缺乏病监测方案》要求,2017—2022年每年在什邡市东、西、南、北、中5个方位各随机抽取1个镇/街道作为监测点,在各监测点随机抽取20名(2017年10名)孕妇,采集其家中食用盐样和1次随机尿样,检测盐碘和尿碘含量。分析不同年份、年龄组、孕期孕妇碘盐覆盖率、合格碘盐食用率及孕妇尿碘水平。用秩和检验进行盐碘和尿碘的比较,用χ^(2)检验进行率的比较,用Spearman秩相关分析进行尿碘和盐碘相关性分析,检验水准α=0.05。结果2017—2022年什邡市共监测553份孕妇家中盐样,盐碘中位数26.55 mg/kg,碘盐覆盖率为99.28%,碘盐合格率为92.90%,合格碘盐食用率为92.22%。不同年份孕妇家中食盐碘含量、碘盐合格率、合格碘盐食用率差异均有统计学意义(H=20.989,χ^(2)=17.701,χ^(2)=20.831,P均<0.05),碘盐覆盖率差异无统计学意义(χ^(2)=4.326,P=0.504)。2017—2022年什邡市共采集553份孕妇尿样,尿碘中位数为139.70μg/L。不同年份孕妇尿碘水平、分布差异均有统计学意义(H=26.866,χ^(2)=20.482,P均<0.05)。孕妇盐碘含量与其尿碘含量无相关关系(r=-0.002,P=0.959)。结论什邡市孕妇碘营养总体上处于碘缺乏状态。建议多途径加强碘缺乏病防治知识宣教,推广孕妇专用碘盐,加强孕妇人群碘营养监测,精准指导孕妇科学补碘。
Objective To understand the iodine nutrition status of pregnant women in Shifang,so as to provide scientific basis for the adjustment of prevention and control policies for iodine deficiency disorders in pregnant women.Methods According to the“Iodine deficiency surveillance program of Sichuan province(revised in 2013)”and“Iodine deficiency surveillance program of key population of Sichuan province”,one town(district)was randomly selected from each of five areas in Shifang(i.e.,east,west,south,north and central)as the monitoring sites.Then,20 pregnant women were randomly selected from each monitoring site every year,except in 2017(10 pregnant women).The edible salt sample and one random urine sample were collected to detect the iodine content.The consumption rate of qualified iodized salt and the urinary iodine level of pregnant women in different years,age groups and pregnancy periods were compared.The Rank sum test was used to compare the levels of salt iodine and urine iodine,Chi-square test was used to compare the rates,and the correlation between urinary iodine and salt iodine was analyzed by Spearman's rank correlation analysis.The test stamdard wasα=0.05.Results From 2017 to 2022,553 salt samples from pregnant women's homes were monitored;the median of salt iodine was26.55 mg/kg,the coverage rate of iodized salt was 99.28%,the qualified rate of iodized salt was92.90%,the consumption rate of qualified iodized salt was 92.22%.There were statistically significant differences in salt iodine content,the qualified rate of iodized salt and consumption rate of qualified iodized salt in different years(H=20.989,χ^(2)=17.701,χ^(2)=20.831,all P<0.05).However,no statistically significance in iodized salt coverage in different years was observed(χ^(2)=4.326,P=0.504).From 2017 to 2022,553 urine samples of pregnant women were collected,and the median of urinary iodine was 139.70μg/L.The differences in urinary iodine level of pregnant women in different years were statistically significant(H=26.866,χ^(2)=20.4
