Functional Differences Found in the Elderly Living in the Community

Introduction: Successful aging lies in cognitive and functional maintenance, and in the optimal performance of daily tasks that keep the elderly free of disability and dependence. However, there is little evidence for functional differences for gender and age, and how cognitive and physical demands in past working lives can affect them, to design more personalized occupational therapy interventions to prevent functional and cognitive impairment. Method: This observational descriptive study evaluated 367 older adults living in a community with subjective memory complaints and scored between 24 and 35 with the Spanish version of the "Mini-Mental State Examination (MEC-35)". Basic activities of daily living (BADL) were studied with the Barthel Index, while instrumental ADL (IADL) were examined with the Lawton-Brody scale. Functional differences for gender, age, and physico-mental occupation were examined. Results: The significant differences found for gender indicated that men did better in BADL (p = 0.026) and women better performed IADL (p < 0.001). Differences between age groups suggest that the younger group (aged 64-75) obtained better results for BADL (p = 0.001) and IADL (p < 0.001). For physico-mental occupation, statistically significant differences were found only in IADL for mental (p = 0.034) and physical occupation (p = 0.005). Conclusions: Gender, age, and the cognitive and physical demands of occupational stages, can be important predictors of cognitive and functional impairment. These results can be generalized to other health centers in the province and to other Spanish Autonomous Communities because their socio-demographic variables are similar. It would be interesting to carry out multimodal personalized interventions that consider the factors that might affect functional impairment to preserve personal autonomy.
