摘要
目的调查河南省碘缺乏病病情防治现状，推动可持续防治策略的完善。方法2011年，采用按人口比例概率抽样法（PPS）分层抽样，在全省选取30个县．每个县抽取1所小学，每所小学抽取8～10岁学生40名，B超检查抽取儿童甲状腺，采用中国联合型瑞文测验（农村和城市修订版）进行智力测定，采集其家中食用盐样，直接滴定法测定盐碘，另采集其中的12名儿童尿样，采用砷铈催化分光光度法测定尿碘，采用3日称量法测算其所在家庭中居民人均食盐摄入量。在每所抽到学校的5年级学生中抽取30名学生，在学校所在乡及相邻的2个乡抽取孕妇和哺乳期妇女各30人，采用统一试卷进行健康教育调查。结果①8～10岁儿童（1201人）甲状腺肿大率为4．5％（54／1201）；智商（1080人）为107．75±16．81；8～10岁儿童（358人）尿碘中位数为201．4μg／L。②全省盐碘（1200份）中位数为28．6mg／kg，碘盐覆盖率为98．8％（1186／1200），合格碘盐食用率为93．0％（1116／1200）。⑧居民每日平均食盐摄人量为10．5g。④全省问卷调查小学5年级学生1084名，平均得分4．2分；问卷调查家庭主妇961名，平均得分4．4分。结论河南省各项碘缺乏病防治技术指标保持消除碘缺乏病状态，加强健康教育、增强群众防病意识依然是今后的重要工作。
Objective To analyze the present situation of iodine deficiency disorders （IDD） in Henan Province, and to promote implementation of sustainable control strategies. Methods In 2011, a stratified proportion to population probability sampling（PPS） method was used to survey 1200 children aged 8 to 10 in 30 counties of the province. One primary school was selected in each chosen county. Goiter, intelligence quotient （IQ）, urinary iodine and salt iodine level were studied. Meanwhile, 12 families per capita salt intake was investigated. In each school, 30 5th-grade students and 30 pregnant and lactating women in the school townships and adjacent neighboring townships were selected to carry out questionnaire survey on health education with unified papers. Results ①The goiter rate of children aged 8 to 10 by B ultrasound was 4.5% （54/1201） ; the IQ of 1080 children was 107.75 ± 16.81 ; median urinary iodine level of 358 children was 201.4μg,/L. ②The median of salt iodine content was 28.6 mg/kg, the coverage rate of iodized salt was 98.8% （1186/1200）, and qualified rate of iodized salt was 93.0% （1116/1200）. ③The residents average daily salt intake was 10.5 g. ④Average score of the questionnaire survey of 1084 5th-grade students was 4.2 points. Average score of 961 housewives was 4.4 points. Conclusions Various technical indicators show that IDD is in a sustained elimination state in Henan Province. Strengthen health education, enhance public awareness of disease prevention is still the important work ahead
