目的调查上海市区老年人社区获得性肺炎的月罹患率,了解社区获得性肺炎在上海市区老年人群中的流行现状。方法针对性抽取上海市区新华街道和半淞园街道为研究现场,以两街道内所有户籍人群中65岁及以上的老年人(共16000人)作为研究对象,调查2004年2月至3月期间的1个月内老年人社区获得性肺炎新近发病情况,以计算老年人社区获得性肺炎月罹患率。结果上海市区老年人社区获得性肺炎确诊病例月罹患率为0.21%(95%CI0.14%⁰.29%),疑似病例月罹患率为0.10%(95%CI0.06%⁰.16%),总的月罹患率为0.31%(95%CI0.23%⁰.41%)。男性月罹患率为0.32%(95%CI0.21%⁰.48%),女性月罹患率为0.29%(95%CI0.19%⁰.43%)。随着年龄的增加,社区获得性肺炎月罹患率逐渐增加,经趋势χ2检验有统计学显著意义。结论上海市区老年人社区获得性肺炎总的月罹患率为0.31%,略低于美国报道的水平。月罹患率随年龄增加而逐渐增加。
