| 目的 了解全民食盐加碘10年后碘盐覆盖率、合格碘盐食用率＞90%的地区孕妇和哺乳期妇女及婴幼儿的碘营养状况,评价碘盐作为人体碘的主要来源是否能满足碘缺乏病重点人群的碘营养需要和重点人群的碘营养状况.方法 在碘盐覆盖率、合格碘盐食用率＞90%的地区,随机选择不同生理时期的孕妇、哺乳期妇女及新生儿、周岁以内婴儿,对孕妇、哺乳期妇女进行尿碘检测和甲状腺功能测定,哺乳期妇女同时进行乳碘检测,新生儿进行促甲状腺激素(TSH)检测,周岁以内婴儿进行尿碘检测.结果 孕早、中、晚期,哺乳3个月以内和哺乳7个月以上的妇女,尿碘中位数分别为174.18、180.37、147.42、126.27和145.26 μg/L,除孕晚期妇女外其余各组妇女的尿碘中位数均达到了WHO推荐标准,但仍有部分重点人群存在碘营养不足;婴儿的TSH均在新生儿甲状腺功能筛查正常参考值范围之内,TSH＞5μIU/ml所占的比例为14.5%;哺乳3个月以内和7个月以上的妇女,乳碘中位数分别为240.34 μg/L和121.78 μg/L.哺乳3个月以内妇女,乳碘＜150 μg/L所占的比例低于哺乳7个月以上的妇女,统计学检验,P＜0.01;哺乳期妇女的乳碘与其婴儿的尿碘呈很好的相关性;孕妇、哺乳期妇女TSH不在正常参考值范围的占15.4%,TSH异常者主要分布在尿碘＜150 μg/L妇女中.结论 在碘盐覆盖率、合格碘盐食用率＞90%的地区,在饮食结构比较单一的情况下,碘盐作为主要的碘来源基本能满足孕妇、哺乳期妇女和婴幼儿的碘营养需要.但仍有部分人群存在碘营养不足,需加强特需人群的碘营养监测,将重点人群碘营养监测纳入常规监测,并采取适时适量补碘. |

| Objective To assess the iodine status of pregnant women, lactating women and babies and to understand if iodized salt as the main iodine source had met the need of people' s demand in regions where iodized salt coverage rate had been over 90% for the last five years. Methods Pregnant and lactating women, newborns and babies were selected randomly in region where iodized salt coverage rate had been more than 90 % for the five years. Urine iodine levels of pregnant and lactating women, newborns and
babies, milk iodine of lactating women and thyroid-stimulating hormone(TSH)of newborns were measured Results The median urinary iodine(MUI) of people other than those recently pregnant women, had reached the MUI criterion recommended by WHO with the results as 174.18, 180.37，147.42,126.27,145.26ug/L,respectively. The percentage of TSH>5 uIU/ml of newborns was 14.5%·
The median milk iodine of lactating women were in the range of 100-200 ug/L. The percentage of milk iodine<150 ug/L of early lactating women was less than that of late Lactating women ( P < 0. 01).There was a good correlation between urine iodine of babies and milk iodine of lactating women. The abnormal TSH of women was 15. 4 %. The abnormal TSH mainly existed in women whose urinary iodine level were lower than 150u/gL. Conclusion Iodized salt as the main iodine source could basically meet the need of pregnant women,lactating women and babies whose diet structure was simple in the region. However,some people in the area were still under the status of iodine deficiency suggesting that surveillance should be enhanced in people who need more iodine and efficient measures, should be taken. |
