Perceived neighborhood social cohesion and functional disability among older adults: The moderating roles of sex, physical activity, and multi-morbidity.

Though the Ghanaian social structure is largely communal in several of its social life and social spaces, the extent to which cohesive neighbourhood affects functional ability of older persons and the moderating factors of the relationship, are unknown in Ghana. This study examines the moderating roles of sex, multimorbidity, and physical activity on the association between neighbourhood social cohesion and functional disability among older people in Ghana. A cross-sectional study of 4,446 people-50 years and older-from WHO's Study on global AGEing and adult health Ghana Wave 2 was employed. Functional disability-WHO Disability Assessment Schedule 2.0-and neighbourhood social cohesion measured with community-level participation, perceived trust and safety were studied. Generalised Logistic regressions with interactional tests were used to examine the associations. A more socially cohesive neighbourhood was significantly associated with a lower functional disability among older people (OR = 0.94, 95%CI: 0.93, 0.94; P<0.001). A similar relationship was found for community-level participation (aOR = 0.94, 95%CI: 0.94, 0.95; P<0.001) and perceived trust (aOR = 1.00, 95%CI: 0.99, 1.00; P<0.001). Community-level participation is associated with a lower functional disability among older people who were physically active (aOR = 0.98, 95%CI: 0.96, 0.99; P<0.001). Among the three individual-level measures of neighbourhood social cohesion, only physical activity (OR = 0.98, 95%CI: 0.98, 0.99; P<0.01) moderated the association between community-level participation and functional disability. Community-level participation, along with physical activity, may be relevant in improving functional ability among older people. The results highlight the usefulness of policy to ensure a more socially cohesive neighbourhood for older people in Ghana to improve their quality of life.
