Abstract MP75: Characterization of Physical Activity Patterns From Mid-Life to Older Adulthood: The Atherosclerosis Risk in Communities (ARIC) Study
Introduction: Lack of physical activity is associated with cardiovascular disease and mortality. Studies that characterize patterns of change in physical activity from mid- to late-life are limited.
Objectives: To examine variation in physical activity patterns from mid-life to older adulthood in a large, population-based cohort by socio-demographic and cardiovascular factors.
Methods: The study population included 5,627 (58% female, 21% African American, mean age at visit 1: 52 years) ARIC participants who completed a modified Baecke physical activity questionnaire at visits 1 (1987-1989), 3 (1993-1995), and 5 (2011-2013). Using the reported type, duration (hours/week), and frequency (months/year) of up to four leisure activities over the past year, estimates of average min/wk spent on moderate to vigorous intensity activities (MVPA) were computed. The AHA “Life’s Simple 7” physical activity recommendations for adults were applied: Poor (0 min/wk MVPA), Intermediate (1-74 min/wk vigorous or 1-149 min/wk of MVPA), and Ideal (>75 min/wk vigorous or >150 min/wk MVPA) to assess temporal changes across these categories from visits 1 to 5, by sex, race, education level, diabetes and hypertension by visit 5.
Results: An increase in the prevalence of Ideal physical activity was observed from mid- to late-life, particularly in Caucasian males with education beyond high school (Figure 1). The prevalence of Poor physical activity was >25% at both time periods in all groups, but highest among African Americans. Increases in the prevalence of Ideal physical activity from mid-life were greater among adults who did not develop diabetes or hypertension compared to those who did.
Conclusion: These results suggest that individuals who reach older adulthood without severe comorbidity report higher levels of MVPA late in life; although, a high proportion of aging adults report not engaging in MVPA. Factors predicting changes and stability in MVPA levels through this important life transition require further elucidation.
