The ADL disability rate was higher in rural area than in urban area (12.4% vs. 11.8%, P=0.039). And it increased significantly with age (P<0.05). Multivariate logistic regression showed besides urban-rural difference (P=0.031), age (P=0.013), education level (P=0.015), physical activity (P=0.001) and stroke (P<0.001) were related factors influencing ADL disability.
