摘要
[目的 ]了解当前盐碘水平下 ,广东省部分地区哺乳妇女及其婴幼儿的碘营养状况。 [方法 ]采用一次性点状调查法 ,选择 3个基本代表广东轻、中、重缺碘地区深圳、佛冈和乐昌的城市和农村各两个点 ,调查哺乳妇女及其婴幼儿的尿碘、盐碘、水碘和乳汁碘等。[结果 ]深圳市、佛冈县和乐昌市的婴幼儿尿碘中位数分别为 2 81 2 μg/L、 2 3 7 1μg/L、2 86 6μg/L ,大于 3 0 0 μg/L的比例分别占 43 3 %、3 4 9%和 49 0 % ;哺乳妇女尿碘中位数分别为 2 0 7 8μg/L、172 6μg/L和 2 60 5 μg/L ,大于 3 0 0 μg/L的比例分别占 3 4 4%、2 3 8%和 41 5 % ;盐碘中位数分别为 3 2 8mg/kg、2 7 5mg/kg和3 6 0mg/kg。[结论 ]当前的盐碘浓度完全可满足哺乳妇女及婴幼儿的碘营养需求 ,部分地区有偏高趋势。建议将我省重度和中度缺碘病区盐碘浓度的平均水平下调至 3 0mg/kg ,轻度缺碘地区下调至 2 5mg/kg。
To investigate the iodine nutrition of the lactating women and infants at the salt iodine level of 35±15mg/kg in Guangdong \ Lactating women and infants in 3 areas (Shenzhen, Fugang and Lechang) of mild, moderate and severe iodine deficiency were selected by “spot sampling” method and the iodine levels in urine, salt, water and milk were measured \ The urine iodine in infants was 281 2, 237 1 and 286 6 μg/L (median) and the percentage (urine iodine>300 μg/L) was 43 3%, 34 9% and 49 0%;The urine iodine in lactating women was 207 8,172 6 and 260 5 μg/L (median) and the percentage was 34 4%, 23 8% and 41 5% respectively The level of salt iodine was 32 8, 27 5 and 36 0 mg/kg (median) respectively \ The iodine nutrition can be satisfied and even higher than needed level with current standard of salt iodine for lactating women and infants It is suggested to adjust salt iodine level to 30 mg/kg in moderate and severe deficiency areas and to 25 mg/kg in mild areas in Guangdong province
