Abstract
INTRODUCTION: Instrumental activities of daily living (IADL) are key indicators of general functional status that are frequently used to assess the autonomy of older adults living in the community. AIMS: To evaluate the changes in IADL in community-living older adults and the role of common mental disorders and physical multimorbidity in predicting these changes. METHOD: A secondary analysis including participants from the Longitudinal Survey on Senior's Health and Health Services. Self-reported sociodemographic and clinical information on chronic conditions were obtained at baseline interview (n = 1615). Measures of IADL were obtained at two time points, 3 years apart. Administrative data on physician diagnoses of chronic diseases were linked to self-reported information. Logistic and multinomial regression models were used to study the outcomes of interest. RESULTS: More than one-third of participants reported disability. Significant increase in global and specific IADL tasks disability were observed over time. Concurrent mental and physical chronic conditions predicted persistent and future incidence of disability. CONCLUSIONS: We draw attention to the synergistic effect of mental and physical co-morbidities on IADL functioning and to the importance of the simultaneous management of these conditions in order to prevent disability, future decline and the associated health and societal burden.Implications for RehabilitationBy establishing the prevalence of global and specific IADL disability, we can better recognize the needs of older adults and inform health and social care planning.Influenced by the morbidity profile, older adults may experience decline, improvement or maintenance of autonomy in IADL over time.The presence of synergistic effect of physical and mental chronic conditions on functioning suggests that their simultaneous management is crucial in delaying or preventing disability.Reports of significant impairment in tasks such as taking medication calls attention to the need for increased accessibility to programs on medication management.The progressive loss of ability to take medication among multimorbid patients emphasize the need for therapeutic plans that circumvent polypharmacy.
