娄底市麻疹流行病学分析

目的 详细了解娄底市麻疹流行情况及其流行病学特征,为有效控制麻疹提供科学依据供各级领导和专业人员参考.方法 全部资料录入或导入MS-Excel 进行统计并作图,比较分析用SPSS 13.0版完成.结果 1978～2005年共报告麻疹31 963例,年均发病率31.18/10万, 历年发病率与接种率呈明显负相关(r-0.802,P＜0.01).发病从高到低后回升,可分为3个时段,年均发病率分别为95.94/10万、4.06/10万和9.66/10万,各时段各县市区发病率差异极其显著(χ254 636.36,P＜0.000 1).整个发病趋势第1时段形成3个高峰之后,1987～2000年一路走低,其中1993～1994年形成一个低谷,至2004年再度形成一个相对高峰.共报告麻疹死亡76例,病死率0.24%.1991～2005年整个发病季节集中在3～6月,但在2004年回升高发时发病高峰在2～4月.2001～2005年麻疹发病数男女性别比为1.94: 1,年龄分布最小23日,最大60岁,5岁以下儿童占56.89%,散居儿童发病数占总数的53.87%,其发病率与幼托儿童和学生比较有统计学意义(χ2921.46,P＜0.000 1).结论 娄底市麻疹发病率总体下降89.93%,但近年有上升趋势,上升原因主要为计划免疫滑坡,存在免疫空白人群.
