Positive Aging Expectations Are Associated With Physical Activity Among Urban-Dwelling Older Adults

Purpose: Regular physical activity is a key component of healthy aging, but few older adults meet physical activity guidelines. Poor aging expectations can contribute to this lack of activity, since negative stereotypes about the aging process can be internalized and affect physical performance. Although prior cross-sectional studies have shown that physical activity and aging expectations are associated, less is known about this association longitudinally, particularly among traditionally underrepresented groups. It is also unclear whether different domains of aging expectations are differentially associated with physical activity.Design and Methods: The number of minutes/week of physical activity in which Baltimore Experience Corps Trial participants (N = 446; 92.6% African American) engaged were measured using the CHAMPS questionnaire, while their aging expectations were measured using the ERA-12 survey. Linear mixed effects models assessed the association between physical activity and aging expectations over 2 years, both in full and sex-stratified samples. Separate models were also fit for different ERA-12 domains.Results: We found that higher overall expectations regarding aging are associated with higher engagement in moderate-to high-intensity physical activity over a 2-year period of time for women only. When the ERA-12 domains were examined separately, only the physical domain was associated with physical activity, both in women and overall.Implications: Low expectations regarding physical aging may represent a barrier to physical activity for older adults. Given that most older adults do not meet recommended physical activity guidelines, identifying factors that improve aging expectations may be a way to increase physical activity levels in aging populations.
