摘要
目的调查2017年新疆维吾尔自治区(新疆)不同地区8～10岁儿童和孕妇的碘营养状况,为制定干预措施提供参考依据。方法采用分层整群随机抽样方法对哈密市、塔城市、阜康市,新源县、乌鲁木齐市天山区、和田县、阿勒泰市、莎车县、新和县和博湖县10个地区开展饮用水水碘含量检测;在每个调查点分别检测200名8～10岁儿童和100名孕妇的随机尿和食盐碘含量;并采用超声检测全部儿童甲状腺容积。结果 10个地区水碘分布范围为1.81～21.43μg/L,中位数3.40(2.01～6.36)μg/L。8～10岁儿童甲状腺肿大率为1.40%;盐碘中位数为27.89(25.12～30.54)mg/kg;8～10岁儿童和孕妇尿碘中位数分别为198.21(132.90～272.03)和153.10(89.00～240.81)μg/L,尿碘分布存在地区差异。结论新疆大部分地区外环境水碘含量较低;人群碘营养水平受饮用水水碘浓度影响。8～10岁儿童和孕妇总体处于碘适宜水平;部分地区孕妇存在碘不足风险,水碘浓度<5μg/L地区的孕妇碘营养状况应引起重视。建议继续加强重点地区和重点人群的科学补碘措施。
Objective To analyze and evaluate the iodine nutrition status of 8–10 years old children and pregnant women and in areas with different water iodine contents in Xinjiang and provide evidence for appropriate iodine supplement.Methods Using stratified cluster random sampling method,10 areas of investigation,i.e.Kumul,Tacheng,Fukang,Xinyuan,Tianshan district of Urumqi,Hotan,Altay,Shache,Xinhe and Bohu,were selected to carry out the testing of iodine content in drinking water.The urine and salt iodine content of 200 children aged 8–10 years and 100 pregnant women were detecteded at each survey site.The thyroid volumes of all children aged 8–10 years were detected by using B ultrasound examination.Results The water iodine contents in 10 areas of Xinjiang ranged from 1.81 to 21.43 g/L,the median was 3.40(2.01–6.36)μg/L.Thyroid enlargement rate was 1.40%,The median of salt iodine content was 27.89(25.12–30.54)mg/kg;The median of urine iodine level was 198.21(132.90–272.03)μg/L in children aged 8–10 years and 153.10(89.00–240.81)μg/L in pregnant women.There were area specific differences in urine iodine level between children aged 8–10 years and pregnant women.Conclusion The iodine content was low in the natural environment of Xinjiang.The concentration of iodine in drinking water will affect the iodine nutrition status of people,and more attention should be paid to the iodine nutrition status of pregnant women in the areas with water iodine concentration of<5μg/L.The overall iodine nutrition status of children aged8–10 years and pregnant women in the survey area was appropriate,but the risk of iodine insufficient exists in pregnant women in some areas.It is suggested to further strengthen the appropriate iodine supplement in key areas and key populations in Xinjiang.
