摘要
目的 了解四川省孕妇和育龄期妇女碘营养现况,为四川省重点人群碘缺乏病防治提供依据。方法 2022年在全省21个市(州)各选取1个县(市、区),在选取的每个县东、西、南、北和中5个方位各随机抽取1个乡(镇、街道),在所抽取的每个乡随机抽取孕妇和育龄期妇女各20人,调查孕期等基本情况并采集尿样及其家庭食用盐样,在每个乡随机抽取2个村,每个村采集饮用人数最多的末梢生活饮用水1份,检测尿碘、盐碘和水碘含量。结果 分别调查孕妇和育龄期妇女2 108人和2 100人,尿碘中位数分别为166.1μg/L和157.2μg/L;盐样4208份,碘盐覆盖率为99.5%,碘盐合格率为96.8%,合格碘盐食用率为96.2%,加碘盐盐碘均数为27.1 mg/kg、变异系数为14.0%;孕妇和育龄期妇女尿碘中位数分别与其家庭食用盐盐碘均数存在弱相关(rs=-0.269、0.051,P=0.238、0.825);水样210份,水碘中位数2.0μg/L,<40μg/L的比例为99.5%。结论 两类重点人群碘营养现况总体适宜,在外环境普遍缺碘和碘盐普及的情况下需继续加强碘营养监测以及富碘食品食用或碘制剂服用的行为指导。
Objective To understand the current status of iodine nutrition on the pregnant women and women of childbearing age in Sichuan Province,to guide the prevention and control of iodine deficiency among key populations in the future.Methods First,one county(county-level city or district)was selected in each of 21 cities(prefectures)of Sichuan Province in 2022.Then,one town(subdistrict)was selected from each of five directionss(i.e.,east,west,south,north,and middle)of each selected county by using a simple random sampling method.Third,20 pregnant women and 20 women of childbearing age were randomly selected from each town for the iodine content testing of their urine samples and one edible salt sample at their home.Additionally,two villages were randomly selected from each town,and one sample of tap drinking water for the largest number of people was collected for the iodine content testing from each village.Results A total of 2108 pregnant women and 2100 women of childbearing age were surveyed,the median of urinary iodine was 166.1μg/L and 157.2μg/L,respectively.Totally,4208 household edible salt samples were collected.The iodized salt coverage rate,the qualified rate of iodized salt and the consumption rate of qualified iodized salt were 99.5%,96.8%and 96.2%,respectively.The iodine mean of iodized salt was 27.1 mg/kg,and coefficient of variation of iodine in iodized salt was 14.0%.There was a weak correlation between the median urine iodine of pregnant women and the average of their household salt iodine,as well as the women of childbearing age(r_(s)=-0.269、0.051,P=0.238、0.825).210 drinking water samples were collected,the median water iodine was 2.0μg/L,and the proportion of water iodine below 40μg/L was 99.5%.Conclusions The current status of iodine nutrition in two key groups mentioned above was generally suitable.However,it is necessary to strengthen the investigation and evaluation of their iodine nutrition,as well as effective health behavioral guidance for consuming iodine rich foods or iodine containing preparations in the background of widespread iodine deficiency in the natural environment and universal salt iodization.
