Advanced Activities of Daily Living (AADLs) and cognitive performance in community-dwelling elderly persons: Data from the FIBRA Study - UNICAMP

Objective The aim of this study was to investigate the relationship between participation in advanced activities of daily living (AADLs) and cognitive performance in community-dwelling elderly persons. Method The data presented is drawn from the population-based study entitled Frailty Profile of Elderly Brazilians (FIBRA-Unicamp). The sample comprised 2,549 older adults without cognitive impairments suggestive of dementia. Data was collected relating to socio-demographic characteristics (sex, age, years of education and family income), health status (number of diseases and depressive symptoms), cognitive performance (Mini-Mental State Examination - MMSE) and self-reported social, physical and intellectual AADLs. Results Mean MMSE scores were significantly higher among men, younger individuals and those with more years of education, higher income, fewer diseases and fewer depressive symptoms. Multivariate linear regression analysis and hierarchical regression analysis showed that years of education, family income and participation in intellectual AADLs were positively associated with cognitive performance. Conclusion The findings suggest that these factors may have a protective role in cognitive aging and that participation in intellectual AADLs can represent a feasible strategy for the promotion of mental health among older adults
