我国银屑病的年发病率及年龄易患率

本文报告1984年我国银屑病流行学调查结果:我国城市银屑病年发病率平均为0.20‰,我国农村银屑病年发病率平均为0.08‰,全国银屑病年发病率约为0.10‰.银屑病年发病率北纬35°以北的地区显著高于南方;城市显著高于农村;男性显著高于女性(P值均小于0.01).银屑病年发病率与年患病率、纬度呈显著的正相关、而与年平均气温、年平均相对湿度呈显著的负相关.银屑病年龄发病率似乎比银屑病初发年龄构成比更确切地反映银屑病的年龄易患性.

Annual incidence and age-liability of psoriasis in China

A nationwide sample screening of psoriasis was carried out in 1984. The mean annual incidence rates of psoriasis in urban and rural areas were 0.20‰ and 0.08‰ respectively. The mean annual incidence rate of psoriasis in China was 0.10‰ approximately. The annual incidence of psoriasis was significantly higher in areas northern to 35° north, latitude, in urban areas than in rural areas, and in males than in females (P<0.01). The annual incidente of psoriasis showed significant positive correlation with the annual prevalence of psoriasis and showed significant negative correlation with the mean temperature and the mean relative humidity during the year. The age-incidence of psoriasis reflected the age-liability to psoriasis more reasonably and reliably than the proportion of age at onset of psoriasis did.
