Description:Introduction:
This study examined feasibility and effectiveness of an intensive lifestyle intervention adapted for people with impaired mobility.
Design:
Randomized, wait-list controlled trial. Experimental group immediately received the 12-month weight loss program; wait-list control group received it after a 6-month delay. Between-group comparisons were conducted for 6-month RCT study design. Repeated measures were conducted for both groups combined after receiving the 12-month intervention. Data were collected August 2015—February 2017 and analyzed 2017.
Setting/Participants:
Community-based sample, hospital-based delivery. Participants with impaired mobility (N=66) were middle-aged (49.80±11.37 years), mostly White (66.7%), female (66.7%), and most commonly had spinal cord injury (47.0%).
Intervention:
The 12-month GLB-AIM delivers 23 group-based sessions that promote weight loss through reducing caloric intake and increasing physical activity.
Main Outcome Measures:
Effectiveness measured as change in weight and time spent in moderate physical activity (MPA) were primary outcomes. Feasibility was assessed in 12-month combined-group analyses, measured as retention, attendance, and dietary self-monitoring.
Results:
Six-month RCT results show immediate and delayed groups differed significantly (p < 0.05) in weight (−1.66 ± 4.42 kg loss vs. 0.05 ± 4.15 kg gain) and MPA (52.93 ± 90.74 min./wk. increase vs. −14.22 ± 96.02 min./wk. decrease), accounting for baseline weight, time with disability, and age of onset. Twelve-month results with groups combined demonstrate 74.2% retention and 77.7% core session attendance. Self-monitoring was higher in the delayed group (77.3%), who used a smartphone app, than immediate group (47.3%) who mostly used paper trackers. Participants achieved significant 12-month weight loss of 3.31 ± 10.13 kg (d = 0.33) in mixed modeling analyses with groups combined, yet did not significantly increase MPA.
Conclusion:
GLB-AIM is a feasible, effective approach to teach healthy lifestyle skills to individuals with mobility impairment, yielding modest weight loss and enhanced self-efficacy.
