Objective To examine the impact of International Physical Activity Questionnaire (IPAQ) physical activity intensity on to the prevalence of diabetes mellitus among Chinese elderly. Methods A total number of 1996 residents aged 50 or above living in Guangzhou city were recruited from the phase 3 of the Guangzhou Biobank Cohort Study. Information on physical activity and fasting plasma glucose status was derived from standardized interviews and laboratory assays. Results Among the participants who were classified as physically active (60.0%), moderate active (29.8%) and inactive (10.2%), the prevalence rates of type 2 diabetes mellitus were 9.1%, 12.0%and 14.2%,respectively. After adjustment on age, sex, obesity and other potential confounding factors, data from logistic regression model showed that the odds ratios (95% confidence interval) for diabetes on subjects in physically moderate active and active group were 0.75 (0.46-1.26)and 0.60 (0.38-0.97) respectively with P for trend as 0.03, when comparing to those physically inactive ones. Conclusion Promotion of physical activity might have had some effects in reducing the risk of diabetes mellitus among the older adults.
