对实施1/2万碘盐为主的综合性防治措施,地甲病基本控制阶段流行病学规律进行了探讨。470,962人的病情调查资料显示,居民患病率和7～14岁中小学生肿大率较防治前显著降低,患病率与年龄的关系为患病率随年龄增高而增高,10岁以上各年龄组男女患病率有显著差异,现患病人的分型构成与病区类型、年龄、性别有关,分度构成表现为Ⅰ～Ⅱ°病例占现患的绝大部分。4,119份尿碘分析表明,居民缺碘已纠正,均值在150～180μg/gCr 之间。24小时甲状腺吸~(131)碘率显著降低。血清 T_3、T_4和 TSH 在正常范围。
On the implementation of 1/2 million iodized salt-based comprehensive prevention and control measures, the basic control phase of endemic disease epidemic rules were discussed. According to the survey data of 470,962 people, the prevalence rate of residents and primary and secondary school students aged 7 ~ 14 were significantly lower than that before prevention and treatment. The prevalence and age were related to the prevalence increasing with age, There were significant differences in prevalence between men and women. The types of patients present were related to the type, age and gender of the ward. The patients with Ⅰ ~ Ⅱ ° scores accounted for most of the cases. 4,119 urine iodine analysis showed that residents have been corrected for iodine deficiency, the average value of 150 ~ 180μg / gCr between. 24 hours of thyroid suction ~ (131) iodine rate was significantly reduced. Serum T_3, T_4 and TSH in the normal range.
