Applying the World Health Organization{\textquoteright}s International Classification of Functioning, Disability and Health (ICF), a well-established biopsychosocial framework, we explored PA participation among older adult with type 2 diabetes. Method: Using data from the Health and Retirement Study and the RAND Center for the Study of Aging (N = 2,016; mean age = 73.19; SD = 6.16), we conducted hierarchical stepwise regression analysis to evaluate the relative contribution of different biopsychosocial predictors to PA {\textendash} namely, body functions and structure, activity and participation, personal, and environmental factors. Results: Altogether, biopsychosocial factors accounted for 20\% of the variance in PA participation. Of the personal factors, high extraversion and low neuroticism explained approximately 54\% of the variance in PA among the older adults {\textendash} beyond sociodemographics. Low body mass index, reduced pain, reduced depression, and higher cognitive functioning also had good explanatory power (25\% of explained variance), whereas activity participation and environment did not (10\% each). Conclusion: Aligning care with components of the ICF will help to ensure a focus on person-centric practices and, in turn, optimize participation outcomes such as PA.}, keywords = {Physical activity, type 2 diabetes}, doi = {10.1017/jrc.2021.7}, author = {Chenchen Yang and Mpofu, Elias and Li, Xiaoli and Dorstyn, Diana and Li, Qiwei and Brock, Kaye} }
