Groessl EJ, et al. - Researchers used data from a multisite, randomized controlled trial— the Lifestyle Interventions and Independence for Elders study, wherein, physical activity was compared to health education among 1,635 randomly assigned sedentary older adults at risk for mobility disability (2010-2011)—to report quality-of-life outcome results. They used the following measures to evaluate study participants: demographic information, comorbidity, timed 400-meter walk, the Short Physical Performance Battery, and the Quality of Well-Being Scale. They noted that, among all participants, quality of life declined over time; however, those assigned to the physical activity intervention demonstrated a slower decline in health-related quality of life. Furthermore, adherence to interventions was correlated to higher health-related quality of life among all participants. Overall, according to findings, declining mobility measured by physical performance is associated with lower quality of life in sedentary older adults. Adherence to physical activity interventions, however, may slow the decline in quality of life, and targeting specific subgroups may improve intervention results.
