摘　　要：目的分析淮南市高水碘和非高碘地区儿童与孕妇碘营养状况,为分类指导、科学补碘提供科学依据。方法全市非高碘县区,每个县区按东西南北中抽取5个乡镇;高碘地区采用系统抽样方法,每个县区抽取5个行政村;每个被抽取乡镇(村)各抽取8~10周岁非寄宿学生40人和孕妇20名,采集其尿样和家中盐样检测;同时采用B超法检测学生甲状腺容积。结果高碘地区结果非高碘地区居民户合格碘盐食用率97.33%,儿童尿碘中位数244.25μg/L,儿童甲肿率0.29%;孕妇尿碘中位数171.8μg/L;高碘地区居民户碘盐覆盖率为100%,儿童尿碘中位数339.8μg/L,儿童甲肿率1.43%,孕妇尿碘中位数203.3μg/L。结论淮南市非高碘地区持续保持消除碘缺乏病状态。非高碘地区儿童碘营养整体处于大于适宜量范围,但孕妇碘营养整体处于适宜水平;高碘地区儿童碘营养过量,孕妇碘营养适宜。应落实因地制宜、分类指导和科学补碘的防控策略。Objective To analyze iodine nutritional status of children and pregnant women in areas with high water iodine and non-high iodine in Huainan City,and to provide scientific basis for classified guidance and scientific supplementation of iodine.Methods In non-iodine-rich counties and districts of the city,five townships were selected from each county area according to the east,west,north and south.Five administrative villages were selected from each county by systematic sampling method in high iodine areas.40 non boarding students aged 8-10 years and 20 pregnant women were selected from each selected township(Village).Urine samples and salt samples were collected for detection,and thyroid volume of students was detected by B-ultrasound.Results The qualified iodized salt consumption rate was 97.33%,the median urinary iodine of children was 244.25μg/L,the goiter rate of children was 0.29%,and the median urinary iodine of pregnant women was 171.8μg/L.The coverage rate of iodized salt was 100%,the median urinary iodine of children was 339.8μg/L,the goiter rate of children was 1.43%,and the median urinary iodine of pregnant women was 203.3μg/L.Conclusion The iodine deficiency disorders in non-iodine-rich areas of Huainan City are continuously eliminated.The iodine nutrition of children in non-iodine-excess areas is larger than the appropriate range and the iodine nutrition of pregnant women is at the appropriate level.The iodine nutrition of children in high water iodine area is excessive,and that of pregnant women is suitable.The strategy of prevention and control should be carried out according to local conditions,classified guidance and scientific iodine supplement.
