摘　　要：目的通过测定孕妇儿童尿碘浓度及儿童甲状腺肿大率,了解儿童和孕妇碘营养状况。方法采用随机抽样法在南开区、河东区抽取10个街道办事处,每个街道办事处随机抽取一所小学,在每所小学抽取35名8~10岁非寄宿学生,采集尿样,测量甲状腺容积,计算甲状腺肿大率。在上述每个街道办事处随机抽取10名孕妇(早中晚期分别17、67、16人),采集孕妇尿样检测尿碘含量。结果共测定8~10岁儿童尿样351份,尿碘浓度M(P25,P75)为132(96~180)μg/L,尿碘浓度<100μg/L的个体占28.5%,尿碘>300μg/L的个体占9.1%。;甲状腺B超共检查8-10岁儿童354人,甲状腺体积M(P25,P75)为3.6(2.9,4.4)ml,甲状腺肿大率达8.5%;共测定孕妇尿样100份,尿碘浓度M(P25,P75)为139(119~163)μg/L,尿碘浓度小于150μg/L的个体占66.0%。结论天津市南开区跟河东区孕妇碘营养水平低于适宜水平,8~10岁儿童碘营养水平处于适宜水平,但仍存在碘缺乏及过量的双重风险。Objective To learn the iodine nutritional status of children and pregnant women, through the determination of urinary iodine concentration of children and pregnant women as well as goiter prevalence of children in Tianjin. Methods Random sampling was used to select 10 street areas in Nankai and Hedong districts. 10 pregnant women and 1 primary school were selected in each street area mentioned above. 35 students aged among 8-10 years were randomly selected in each school（gender balanced）. Urinary iodine concentration（UIC） of pregnant women and children were determined. Thyroid B-ultrasonography was conducted to measure the thyroid volume（Tvol） of children, and goiter rate（GR） was calculated. Results 351 urine samples of children were determined. The median UIC [M（P25, P75）] of children was 132μg/L（96-180） μg/L,with 28.5% children UIC〈100μg/L and 9.1% children UIC 〉300μg/L. The thyroid volume of children was 3.6（2.9, 4.4） ml.The GR of children was 8.5%. The median UIC [M（P25, P75）] of pregnant women was 139（119-163） μg/L, with 66.0% pregnant UIC〈150μg/L. Conclusion The iodine nutritional status of pregnant women in Nankai and Hedong districts, was moderate deficiency according to the WHO criteria. The iodine nutritional status of 8-10 years old children was optimal. However, a risk of iodine deficiency and excess still exists.
