Community-based weight management in long-term heart transplant recipients: a pilot study

BACKGROUND: Heart transplant recipients often suffer from obesity, dyslipidemia, and hypertension thought to be related to triple-drug immunosuppression and poor adherence to diet and exercise. A lifestyle intervention that allows recipients to attend a community-based weight management program may improve health outcomes. OBJECTIVE: To determine (1) the effects of attending a community-based weight management program on weight, systolic and diastolic blood pressure, and the lipid profile; and (2) the feasibility of a community-based program for weight management. METHODS: Twenty-one patients (81% male; age 57 years, 99.7 months since transplantation) participated in a randomized clinical trial and received either weight management counseling (control) or a 6-month scholarship to a structured commercial program (treatment). Using simple analysis of covariance models, group differences were assessed and reported as marginal means. RESULTS: At baseline, there were no demographic differences between groups. There were no differences in outcome variables except weight (control, 102.1 kg vs treatment, 98.3 kg; P= .05). After 6 months, significant differences were found in weight (control, 100.5 kg vs treatment, 95.6 kg; P= .047) and high-density lipoprotein cholesterol (control, 40.6 mg/dL vs treatment, 49.1 mg/dL; P= .044). A marginally significant difference was found in systolic blood pressure (control, 138 mm Hg vs treatment, 121 mm Hg; P= .07). A decrease in diastolic blood pressure (6 mm Hg) was attributed to treatment effect (P = .16). No differences were noted in total cholesterol, triglycerides, or low-density lipoprotein cholesterol. CONCLUSIONS: The structured commercial program appears to be an effective, feasible alternative to usual care. Findings need to be confirmed in future research with a larger sample.
