Abstract:
Background: The increasing elderly population highlights the importance of comprehending healthy aging by examining the interactions among cognition, daily activities, and lifestyle. This study aims to address this by investigating these relationships within the World Health Organization's Healthy Aging Model. Methodology: A cross-sectional study was conducted with 178 older adults from southern Iran, representing various cognitive levels. Participants underwent assessments to measure cognitive functions, lifestyle preferences, and independence in instrumental activities of daily living (IADL) using the Mini-Mental State Examination, the Lifestyle Assessment Questionnaire for the Iranian Elderly, and the Lawton IADL Scale. Findings: The relationships between the studied variables were identified. Lower cognitive function was found to be associated with decreased engagement in IADL and less-favorable lifestyle choices. Conclusion: Integrating cognition, IADL, and lifestyle into assessments and interventions align with both the domain and process of occupational therapy, thereby enhancing well-being and promoting healthy aging in older adults.
