目的掌握重庆市碘缺乏病现状,为制定防治方案提供依据。方法每个区县随机抽取9个乡镇检查居民食用盐含碘量;抽取东、西、南、北、中5所小学8～10岁儿童各20人检测尿碘;在尿碘检查的学校中抽取1所学校8～10岁60人检查甲状腺;用χ2检验和趋势分析(F)作统计学处理。结果在全市40个区县检查居民食用盐14217户,碘盐覆盖率为98.90%,最低为95.28%,最高为100.00%,合格碘盐食用率为95.59%,最低的区县为90.00%,最高的区县为99.72%;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2393人,肿大率触诊法为7.02%,B超为6.64%,区县肿大率触诊和B超法最低均为5.00%,最高均为8.33%,8、9、10岁年龄组儿童触诊法分别为6.68%(53/793)、6.54%(53/811)、7.86%(62/789),B超法分别为6.81%(54/793)、7.64%(62/811)、5.45%(43/789)。结论重庆市居民食用碘盐措施巩固,人群碘营养充足,儿童甲状腺肿大率已降到较低水平,碘缺乏病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 master the current status of iodine deficiency disorders in Chongqing and provide the basis for developing prevention and treatment programs. Methods Nine townships and townships in each district were inspected to determine the iodine content of household salt. Urine iodine was detected in 20 primary and secondary school children of 8 to 10 years in East, West, South, North and Central China. Urine iodine A total of 60 children aged 8 to 10 years were sampled for thyroid examination. Chi-square test and trend analysis (F) were used for statistical analysis. Results In the 40 districts and counties in the city, 14217 households were inspected for salt consumption. The coverage rate of iodized salt was 98.90%, the lowest was 95.28% and the highest was 100.00%. The qualified iodized salt consumption rate was 95.59% and the lowest one was 90.00% Of the districts and counties was 99.72%; the urinary iodine test was 4050, with a median of 247.20μg / L, accounting for 37.10% over 300μg / L, 25% (10/40) in the counties with a median of 100-200μg / L and 200 Accounting for 57.5% (23/40) with ~ 300μg / L, 17.5% (7/40) with> 300μg / L, 2393 with thyroid examination, 7.02% with palpation and 6.64% with B- The rates of palpation and B-ultrasonography were 5.00% and 8.33%, respectively. The palpation rates of children in the 8, 9 and 10 years old group were 6.68% (53/793) and 6.54% (53/811) respectively, 7.86% (62/789), B ultrasound were 6.81% (54/793), 7.64% (62/811) and 5.45% (43/789) respectively. Conclusion Chongqing residents to eat iodized salt to consolidate the population iodine sufficient nutrition, children’s goiter rate has dropped to a low level, iodine deficiency disease prevention and treatment work achieved remarkable results. However, there is excessive iodine, salt concentration should be reduced iodine.
