The self-made questionnaire and physical activity scale for the elderly(PASE) were used to collect the information including general data and lifestyle. The cognitive ability was evaluated by immediate and delayed word recall，digit span，verbal fluency and the calculation task of reciprocal. Univariate analysis and multivariate linear analysis were used to explore the relationship between lifestyle and cognitive function. Results Univariate analysis showed that the more participation in intellectual and social activities，the more social support，the better the cognitive ability in older patients with T2DM(P<0. OS).Multivariate linear regression analysis showed that moderate and more participation in intellectual and social activities(β=0. 247 0. 432)，and more social support(β=0. 308)could positively predict overall cognitive function(P<0.05).
