浙江省德清县农村社区成人HBsAg阳性率调查

Prevalence of positive HBsAg in adults:a rural community study in China

目的了解中国农村社区成人居民HBsAg阳性率情况。方法采用流行病学现况研究设计,整群抽取浙江省德清县4个农村社区,面对面调查上述社区中所有15～64周岁的社区户籍居民并以ELISA检测HBsAg感染状态。在SPSS11.0中进行数据分析,对于年龄等连续变量,采用独立样本t检验;对于阳性率等分类变量进行χ^2检验。结果在4434名合格对象中,农村社区18～64岁成人居民粗的HBsAg阳性率为7.3%;按照2000年全国人口进行年龄性别标化,标化的HBsAg阳性率为8.0%（男性年龄标化率为8.8%,女性为7.2%）。不同性别人群的HBsAg阳性情况有所不同,男性的HBsAg阳性率明显高于女性（8.8% vs 6.2%）,差别有统计学意义（χ^2=10.52,P=0.001）。结论浙江德清农村社区成人居民HBsAg阳性率仍然较高。
