目的为了解徐州市碘缺乏病防治现状,评价防治措施效果,为制定防治策略提供依据。方法在徐州市缺碘地区内按人口容量比例概率(PPS)抽样方法确定30个点作为监测点,每个监测点用单纯随机抽样法抽取一所学校,每所学校用单纯随机抽样抽取8~10周岁学生40名作为监测对象,保持年龄、性别均衡。查甲状腺,40名学生自带家中食用盐进行盐碘检测,同时抽取12名学生采集尿样,进行尿碘测定,统计甲状腺肿大率、尿碘中位数,碘盐覆盖率、合格碘盐食用率、碘盐合格率、盐碘中位数。结果共监测1 200名8~10周岁学生,甲状腺肿大率为0.75%、尿碘中位数为241μg/L,碘盐覆盖率为96.67%、合格碘盐食用率95.5%、碘盐合格率98.79%、盐碘中位数31 mg/kg。结论徐州市持续维持在国家消除碘缺乏病状态。
Objective To understand the status quo of prevention and treatment of iodine deficiency disorders in Xuzhou and to evaluate the effect of prevention and treatment measures to provide basis for prevention and treatment strategies. Methods 30 points were selected as the monitoring points by the PPS sampling method in the area of iodine deficiency in Xuzhou City. Each monitoring point was sampled by a simple random sampling method. Each school used a simple random sampling to extract 8 ~ 40-year-old students 40 as the monitoring object, to maintain the age, gender balance. Check the thyroid, 40 students take their own home salt for salt iodine detection, while taking 12 students to collect urine samples for urinary iodine determination statistics goiter rate, median urinary iodine, iodized salt coverage, qualified iodized salt Consumption rate, iodized salt pass rate, median salt iodine. Results A total of 1 200 students aged 8-10 years were enrolled in this study. The prevalence of goiter was 0.75%, the median urinary iodine was 241 μg / L, the iodized salt coverage was 96.67%, the qualified iodized salt 95.5% 98.79%, median salt iodine 31 mg / kg. Conclusion Xuzhou City continued to maintain the status of iodine deficiency disorders in the country.
