The scores of non diseased elderly people were much better than that of diseased people in ADL (none-diseased group, 71.3% versus diseased group 55.0%) and mental status (none-diseased group, 44.2% versus diseased group 32.4%) in the grade of high scores, and the proportion of non diseased group (81.5%) among elderly people who have good social relationship was significantly higher than that of diseased group (77.2%). And there was significantly different between the two groups in all of the ADL (χ2 = 338.67, p < 0.001), mental status (χ2 = 183.08, p < 0.001) and social relationship (χ2 = 25.63, p < 0.001) parameters
