Abstract 9766: Impact of Duration on The Results of a Lifestyle Modification Program for The Metabolic Syndrome
Background: We have demonstrated that the staff and facilities of cardiac rehab can be used to treat the metabolic syndrome (MetSyn) in a patient-pay ($350) 3 month life-style intervention program [the Metabolic Fitness Program (MetFit)].
Objective: To determine the relative effectiveness of extending the 3 month MetFit program to 6 months.
Methods: All patients were physician referred and had 3 or more criteria of the MetSyn. Anthropomorphic, physiologic, and biochemical studies were obtained at baseline, 3 and 6 months. The program costs the patient $700 and consists of weekly 45 minute sessions of nutrition, exercise, and behavior education and 45 minutes of exercise supplemented by daily free use of the fitness center.
Results: Of the 72 patients enrolled in the 6 month program, 44.4% were male and mean age was 52.1±9.5 years. Over 90% were obese and 40% were morbidly obese. Based on AHA Guidelines for the MetSyn, 72.2% were hypertensive, 87.5% had impaired fasting glucose, 98.6% had abdominal obesity, 65.3% had elevated fasting triglycerides, and 61.1% had low HDL-C. In this interim analysis, 68 (94%) had completed 3 months, 55 (76%) had completed 6 months and 8 (10%) dropped out of the program. The change in parameters associated with the MetSyn at 3 and 6 months are shown in Table 1. Forty-seven % of patients lost at least one criteria of MetSyn after 6 months of the program compared to 28% at 3 months (p=0.027). At 6 months, 27% no longer had the MetSyn compared to 13% at 3 months (p<.0001).
Conclusions: This interim analysis of the MetFit program targeting the metabolic syndrome suggests that patients will obtain more benefit after 6 months compared to 3 months. Drop-out rate was not affected with the longer program despite the higher cost to the patient. The long term benefits of programs like MetFit remain to be seen.
