1994～2007年北京市先天性甲状腺功能减低症的流行病学研究

Epidemiological study of congenital hypothyroidism in Beijing from 1994 to 2007

【目的】为了获得北京地区先天性甲状腺功能减低症(congenital hypothyroidism,CH)的流行病学分布特征。【方法】对北京市现有的新生儿疾病筛查相关报表和个案信息资料进行描述性分析和统计推断。【结果】14年中北京市确诊CH患儿336名,总患病率为0.28‰,并且患病率呈逐年上升的趋势;男性患病率为0.28‰,女性为0.42‰,男女患病率之比为1∶1.5;患儿中高龄产妇占11.8%,明显高于全部活产儿;未发现CH的患病率存在户籍、出生体重、分娩孕周等的差异。【结论】北京地区CH的患病率呈上升趋势,女性新生儿与高龄产妇分娩新生儿可能是CH的高发人群。
