摘　　要：目的评价碘缺乏病的防治效果,分析影响因素,为制定防治方案提供依据。方法各区县随机抽取9个乡镇检查居民食用盐含碘量;抽取5所小学8～10岁儿童检查甲状腺、尿碘和五年级学生碘缺乏病防治知识;查阅组织领导、防治监测、碘盐管理和健康教育资料,进行综合评分;重庆市对区县评估结果进行复核;用χ2检验作统计学分析。结果全市40个区县检查居民食用盐14217户,合格碘盐食用率为90.00%～99.72%,平均为95.90%,尿碘检测4050人,中位数为247.20μg/L,300μg/L以上占37.10%,区县中位数100～200μg/L占25%(10/40),200～300μg/L占57.5%(23/40),>300μg/L占17.5%(7/40);甲状腺检查16852人,肿大率为3.25%～9.00%,平均为5.80%;学生防治知识平均得分3.1～5.0分,平均为4.4分;防治措施综合评分为86.00～99.00分,平均为95.00分。市级复查中检查食用盐1250户,合格碘盐食用率为90.91%～100.00%,平均为96.88%;甲状腺检查16852人,肿大率触诊和B超法为5.00%～8.33%,平均分别为7.02%和6.64%;防治知识调查1366人,得分2.5～4.9分;防治措施综合评分为88.8～99.5分。结论重庆市有39个区县实现了消除碘缺乏病目标,1个县实现了基本消除碘缺乏病目标,市级层级实现了消除碘缺乏病目标,防治工作取得显著成效。但存在碘过量,须降低食盐加碘浓度。Objective To evaluate the effectiveness of the iodine deficiency disorders（IDD） prevention program and analyze the influencing factors.Methods The level of iodine in resident salt obtained from 9 different towns was determined.The incidence of goiter and urinary iodine of children aged 8-10 year were examined in 5 schools.The knowledge of IDD in the Grade 5 students was evaluated.The data of leadership,monitoring,iodine-salt management and health education were checked.Results were analyzed using the chi-square test.Results 14,217 resident salt samples were examined.The coverage rate of qualified iodized salt was 95.9%（90.00%-99.72%）.4,050 urine samples were analyzed.The median of urinary iodine was 247.20 μg/L,and 37.1% of the sample had a concentration over 300 μg/L.The proportion of 100-200 μg/L,200-300 μg/L and 300 μg/L at county level was 25%,57.5% and 17.5%,respectively.16,852 subjects were examined and the goiter rate was 5.8%（3.25%-9.00%）.The score of student＇s knowledge of IDD was 4.4（3.1-5.0）.The average score of control measure was 95（86-99）.1 250 resident salt samples were re-examined by the county.The coverage rate of qualified iodized salt was 96.88%（90.91%-100%）.16 852 subjects were examined and the goiter rate of palpation and B-ultrasonic examination was 7.02% and 6.64%,respectively.The score of student＇s knowledge of IDD was 2.5-4.9.The average score of control measure was 88.8-99.5.Conclusion Chongqing municipal has achieved the target of elimination of IDD at the province level.39 counties have achieved the target of elimination IDD and 1 county has achieved the target of basal level of elimination of IDD.The concentration of iodine in salt was high and the iodine concentration should be reduced.
