目的了解苏州市吴江区重点人群的碘营养状况,为防治碘缺乏病提供科学依据。方法连续4年开展碘营养监测,每年根据地理方位采用分层随机法抽取8~10岁学龄儿童和孕妇。结果 8~10岁学龄儿童家庭户食用盐的含碘均数为25.56mg/kg,尿碘中位数203.40μg/L;孕妇家庭户食用盐的含碘均数为25.56mg/kg,尿碘中位数151.88μg/L;儿童尿碘不足和过量的比例分别为13.00%和19.60%,孕妇尿碘不足的比例达49.33%;儿童与孕妇尿碘分布差异有统计学意义(P<0.01)。结论吴江区重点人群碘营养状况总体适宜,但是孕妇碘营养水平比学龄儿童低,存在碘缺乏的危险。
Objective To understand the iodine nutrition status of key population in Wujiang District of Suzhou City and provide a scientific basis for the prevention and treatment of iodine deficiency disorders. Methods The iodine nutrition monitoring was carried out for 4 years in a row. The stratified random method was used to select the school-age children aged 8-10 years and pregnant women according to the geographic orientation. Results The average iodine content of salt intake in family children aged 8-10 years old was 25.56mg / kg and the median of urinary iodine was 203.40μg / L. The average iodine content of salt in pregnant women was 25.56mg / kg, The median of urinary iodine was 151.88μg / L in children. The urinary iodine deficiency and overdose in children were 13.00% and 19.60% respectively. The proportion of urinary iodine deficient in pregnant women was 49.33%. The distribution of urinary iodine in children and pregnant women was significantly different (P <0.01) . Conclusion The iodine nutrition status of the key population in Wujiang District is generally suitable, but the iodine nutrition level of pregnant women is lower than that of school-age children, and the risk of iodine deficiency exists.
