PHYSICAL ACTIVITY LEVEL AND RESILIENCE IN OLDER ADULTS: THE INTERNATIONAL MOBILITY IN AGING STUDY (IMIAS)
Lifestyle; Healthy Aging; Mental Health.
Background: Physical (in)activity has been associated with key factors related to healthy aging and longevity. However, the relationship between physical activity level and resilience remains poorly understood in older adults.
Objective: To investigate the relationship between physical activity level and resilience in older adults across diverse socioeconomic, cultural, religious, and geographical contexts.
Methods: Cross-sectional and 2-year longitudinal analysis were conducted using data from 2014 and 2016 waves of the International Mobility in Aging Study (IMIAS; Tirana-Albania, Natal-Brazil, Manizales-Colombia, Kingston-Canada, Saint-Hyacinthe-Canada) where 400 hundred community older adults from both sexes were recruited at baseline in each research site. Physically active (150+ min/week of walking) and inactive (<150 min/week of walking) groups were defined using the Mobility Assessment Tool. Resilience was measured using the Resilience Scale (RS-14). Adjusted multivariate regression models were used to analyze the relationship between physical activity level (active as reference) and resilience.
Results: Inactive older adults showed lower resilience scores in all study sites (p < 0.05). Adjusted cross-sectional (n = 1674; β: -2.81; 95% CI: -3.79; -1.84) and longitudinal (n = 1490; β: -1.90; 95% CI: -2.78; -1.02) analysis demonstrated that physical inactivity was associated with lower resilience scores. Conclusion:Our findings support the idea that physical inactivity is associated with lower resilience in community-dwelling older adults.
