Abstract 14649: Impact of a Weight Management Intervention for Overweight and Obese Cardiac Patients Participating in Rural Cardiac Rehabilitation Programs
Background: Cardiac rehabilitation (CR) is recommended for secondary CVD prevention after cardiac revascularization [coronary artery bypass surgery (CABS) or percutaneous coronary intervention (PCI)]. Most patients (80%) are overweight at entry into CR; however, most CR programs do not include a specific weight loss component.
Purpose: To examine the impact of a 12-week weight management (WM) intervention (6-week home-based telehealth device and 6-week telephone coaching sessions) for overweight and obese cardiac revascularization patients participating in rural CR programs.
Methods: 44 overweight or obese cardiac patients were randomized to a 12-week WM intervention (n=23) or standard care (SC) group (n=21). Weight (% of weight loss), patient activation, using Patient Activation Measure (PAM), and diet intake (3-day diet diary using the Minnesota Nutrition Data System, V 5.0/35) were measured at baseline (before intervention), at 4- and 6-months after CABS or PCI.
Results: Subjects’ mean age was 63.1 ± 9.3 years; the majority was male (70.5%). The WM group had significantly (p<.05) higher mean percentage of weight loss, (M= 4.98% ± 0.03) compared to SC group (M=3.0% ± 0.03) from baseline to 4-months; however, there were no significant differences between groups from 4- to 6-months. Analyses (RM-ANCOVA) of PAM scores (having more confidence, knowledge and action to manage own health) were significantly (p<.05) higher over time for WM group compared to the SC group, using baseline PAM scores as a covariate. There was no significant difference between groups over time in % of Kcal intake compared to recommended target Kcal intake. Both groups consumed more Kcal than their recommended target Kcal intake for weight loss. However, % of Kcal intake exceeding target levels was lower in the WM group compared to SC group at 4-months (M=+16.2% ± 0.5 vs. M=+44.2% ± 0.8) and 6-months (M= +26.4% ± 0.5 vs. M=+56.1% ± 0.7).
Conclusions: The WM intervention group demonstrated improvements in weight outcomes and levels of weight management patient activation. The telehealth WM intervention was successfully delivered to cardiac subjects in rural communities. Results show support for a fully powered randomized trial.
