Neighborhood Mobility and Unmet Physical Activity Need in Old Age: A 2-Year Follow-Up

subject

description

Background: Many older people report a willingness to increase outdoor physical activity (PA), but no opportunities for it, a situation termed as unmet PA need. The authors studied whether lower neighborhood mobility and PA precede the development of unmet PA need. Methods: Community-dwelling 75- to 90-year-old people (n = 700) were interviewed annually for 2 years. Unmet PA need, neighborhood mobility, and PA were self-reported. In addition, accelerometer-based step counts were assessed among a subgroup (n = 156). Results: Logistic regression analyses revealed that lower baseline neighborhood mobility (odds ratio 3.02, 95% confidence interval [1.86, 4.90] vs. daily) and PA (odds ratio 4.37, 95% confidence interval [2.62, 7.29] vs. high) were associated with the development of unmet PA need over 2 years. The participants with higher step counts had a lower risk for unmet PA need (odds ratio 0.68, 95% confidence interval, [0.54, 0.87]). Conclusion: Maintaining higher PA levels and finding solutions for daily outdoor mobility, especially for those with declines in health, may protect from the development of unmet PA need.
