[The trend of proportion among inpatients with gout in 21 hospitals during the past 15 years].
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 (Chi2 = 823.4, P < 0.001). The constituent ratio of hospitalized gout patients in 13 hospitals in southern China increased abruptly (Chi2 = 650.9, P < 0.001); while the constituent ratio in 8 hospitals in northern China increased to a lesser extent (Chi2 = 188.1, P < 0.001). A significant difference was noticed between southern and northern China (Chi2 = 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.
