Abstract
- Background and Objectives The high prevalence of overweight or obesity in older adults is a public health concern because obesity affects health, including the risk of mobility disability. Research Design and Methods The Mobility and Vitality Lifestyle Program, delivered by community health workers (CHWs), enrolled 303 community-dwelling adults to assess the impact of a 32-session behavioral weight management intervention. Participants completed the program at 26 sites led by 22 CHWs. Participation was limited to people aged 60–75 who had a body mass index (BMI) of 27–45 kg/m<superscript>2</superscript>. The primary outcome was the performance on the Short Physical Performance Battery (SPPB) over 12 months. Results Participants were aged 67.7 (SD 4.1) and mostly female (87%); 22.7% were racial minorities. The mean (SD) BMI at baseline was 34.7 (4.7). Participants attended a median of 24 of 32 sessions; 240 (80.3%) completed the 9- or 13-month outcome assessment. Median weight loss in the sample was 5% of baseline body weight. SPPB total scores improved by +0.31 units (p <.006), gait speed by +0.04 m/s (p <.0001), and time to complete chair stands by −0.95 s (p <.0001). Weight loss of at least 5% was associated with a gain of +0.73 in SPPB scores. Increases in activity (by self-report or device) were not independently associated with SPPB outcomes but did reduce the effect of weight loss. Discussion and Implications Promoting weight management in a community group setting may be an effective strategy for reducing the risk of disability in older adults. [ABSTRACT FROM AUTHOR]
