摘要
目的了解沧州市碘盐覆盖率较低地区的儿童和孕妇碘营养水平,为制定科学预防措施提供依据。方法选择碘盐覆盖率较低的4个县和1个碘盐覆盖率较高的县作为调查点,在每个调查点按方位在5个乡(镇)中共抽取8-10岁学生(男、女各半)200人,检测儿童尿碘、甲状腺、家庭食用盐。同时抽取100名孕妇,采集并检测其尿样和家庭食用盐。采集学校所在村的饮用水水样检测水碘。结果共检测水样25份,水碘范围为2.5μg/L-96.6μg/L;对1103名儿童进行了甲状腺检测,甲肿率1.5%;采集儿童家庭食用盐1022份,盐碘中位数0mg/kg,碘盐覆盖率35.6%;采集儿童尿1022份,尿碘中位数158.9μg/L。采集孕妇家庭食用盐503份,盐碘中位数13.7mg/kg,碘盐覆盖率50.3%;采集孕妇尿503份,尿碘中位数125.7μg/L。碘盐覆盖率较低的4个县儿童尿碘中位数、孕妇尿碘中位数明显著低于碘盐覆盖率较高的对照县。碘盐覆盖率与儿童尿碘成正相关关系。结论在碘盐覆盖率较低的地区,水碘在40μg/L-99μg/L范围的儿童碘营养处于适宜水平,孕妇可能会出现碘营养不足;水碘<40μg/L地区的儿童、孕妇都有存在碘营养不足的可能。
Objective To understand the iodine nutrition level of children and the pregnant women living in areas with lower iodized salt coverage rate in Cangzhou City so as to provide a scientific basis for the development of preventire measures.Methods Four counties with lower coverage rate of iodized salt and 1 county with higher iodized salt coverage rate were selected. In each selected county, based on their locations, 200 aged 8 to 10 years old（ half boys and half girls） were selected to detect their urinary iodine, thyroid and household edible salt. In the mean time, 100 pregnant women were selected to detect their urine and household edible salt, and the drinking water samples of the villages where the selected schools were located were also measured for iodine content.Results A total of 25 water samples were measured with iodine content ranging from 2.5 μg/L to 96.6 μg/L.Goiter prevalence of 1 103 children for thyroid detection was 1. 5%. The median iodine content of 1 022 edible salt samples collected from children＇s household was 0 mg/kg,with the coverage rate of iodized salt being 35.6%. A total of 1 022 urine samples were collected, and the median urinary iodine was 158.9 μg/L. In the pregnant women＇s household, 503 samples of edible salt were detected, with median iodine being 13.7 mg/kg,and the coverage rate of iodized salt being 50.3%. The median urinary iodine of503 pregnant women＇s urine samples was 125.7 μg/L. The median urinary iodine of the children and the pregnant women in the counties with lower iodized salt coverage rate were significantly lower than that in the control county with higher iodized salt coverage rate. The iodized salt coverage rate was positively correlated with children ＇s urinary iodine content. Conclusions In areas with low iodized salt coverage rate, when water iodine was in the range of 40 ~ 99 μg/L, children＇s iodine nutrition was at the appropriate level,However, pregnant women could exhibit iodine deficiency. When water iodine was below 40 μg/L, both children and pregnant women could probably suffer from iodine deficiency.
