目的了解和评估秀洲区不同人群碘营养状况,为科学补碘防控策略提供依据。方法采用分层整群抽样的方法对秀洲区居民进行问卷调查、尿碘检测、甲状腺检查和甲状腺功能检测。结果人群尿碘中位数213.43μg/L,尿碘水平<100μg/L占3.61%～40.63%;>200μg/L的为23.44%～79.52%;结节型甲状腺肿大率20.64%,结节型甲肿率随年龄上升而增高(P<0.01);结节型甲肿率女性是男性的1.58倍(P<0.01);甲状腺功能异常检出率为8.86%,甲状腺功能异常检出率女性是男性的1.38倍,甲状腺功能异常检出率40岁以上高于40岁以下,差异有统计学意义(P<0.05);不同碘营养水平甲状腺异常和功能性甲状腺异常差异均无统计学意义(P>0.05)。结论秀洲区居民碘营养状况大多处于适宜至过量的水平,结节型甲肿率高于内陆适碘地区平均水平,且与年龄、性别有关。
Objective To understand and assess the iodine nutrition status of different populations in Xiuzhou District and provide the basis for scientific iodine prevention and control strategy. Methods The stratified cluster sampling method was used to survey residents in Xiuzhou district, urine iodine test, thyroid examination and thyroid function test. Results The urinary iodine median of the population was 213.43μg / L, the urinary iodine level was less than 100μg / L, accounting for 3.61% -40.63%, the rate of> 200μg / L was 23.44% -79.52%, the rate of nodular goiter was 20.64% (P <0.01). The rate of nodular goiter was 1.58 times higher than that of male (P <0.01), the rate of thyroid dysfunction was 8.86%, and the rate of thyroid dysfunction was Which was 1.38 times higher than that of men. The detection rate of abnormal thyroid function was higher than 40 years old and above 40 years old, the difference was statistically significant (P <0.05). There was no significant difference between thyroid abnormalities and functional thyroid abnormalities in different levels of iodine nutrition P> 0.05). Conclusion The iodine nutrition status of residents in Xiuzhou District is mostly suitable to the overdose level. The nodular nodular rate of nodular nodules is higher than the average level of iodine - inland areas in China, and is related to age and sex.
