21家医院痛风住院构成比15年变化趋势分析

The Trend of Proportion among Inpatients with Gout in 21 Hospitals during the Past 15 Years

调查国内２１家城市医院１９７９￣１９９３年间，各年度医院总住院人数和痛风住院人数。结果：１５年间２１家医院合计的痛风住院构成比有直线上升的趋势，χ＾２＝８２３．４，Ｐ〈０．００１；其中南方１３家医院的痛风住院构成比有上升趋势，χ＾２＝６５０．９，Ｐ〈０．００１，北方８家医院的痛风住院构居成比也有上升趋势，χ＾２＝１８８．１，Ｐ〈０．００１；南方与北方医院比较，差异有显著性，χ＾２＝４５．８。

We analyzed data gathered from 21 hospitals in our country from 1979 to 1993 on the total number of hospitalized patients with the number of gout patients. Results showed that the proportion of hospitalized gout patients in 21 hospitals has increased sharply during the past 15 years (χ~2= 823.4, P<0.001). The constituent ratio of hospitalized gout patients in 13 hospitals in southern China increased abruptly (χ~2= 650. 9, P<0. 001);while the constituent ratio in 8 hospitals in northern China increased to a lesser extent (χ~2=188.1, P<0. 001). A significant difference was noticed between southern and northern China (χ~2=45.8, P<0.001). During the past 15 years, the proportion of hospitalized gout patients has been increasing rapidly, with greater extent in the south. This is probably related to the economic development which improves the standard of living and to the changes of food structure.
