The exogenous variables were body functions (hand grip strength, timed \u201cup and go\u201d test score, and body mass index), daily living activities (Korean Instrumental Activities of the Daily Living Scale), social activity participation (social activity engagement, neighbor contacts, and family contacts), and participation in economic activity (frequency).
