Abstract 19742: Effects of a "Health Partner" Intervention on the Metabolic Syndrome
Introduction: The Metabolic Syndrome (MetS) is highly prevalent, afflicting a third of U.S. adults, and confers higher cardiovascular morbidity and mortality. Features of MetS include abdominal obesity, elevated blood pressure, dysglycemia and atherogenic dyslipidemia. While lifestyle modifications are the first-line of MetS treatment, sustained adherence is achieved by a minority of patients. We investigated the effects of a Health Partner (HP) intervention on MetS. Methods and Results: A total of 119 university employees with MetS (51±9 years, 59% women, 26% African Americans) were enrolled in an academic program that promotes clinical self-knowledge and healthier lifestyles at the Center for Health Discovery and Well Being at Emory University in Atlanta, GA. Baseline anthropometric, laboratory and vascular function measurements were used by the HP to generate an action plan with detailed strategies to improve dietary and exercise habits, and subjects returned for follow up at 6 months and annually thereafter for 2 years. Repeated measures ANOVA showed statistically significant changes in waist circumference (p=0.007; baseline vs. 2 years: 103.1 vs. 98.2 cm), weight (p=0.004; 216.1±35 vs. 204.9±37 lbs), body fat percent (p=0.042; 39.6±7.4 vs. 38.1±7.9), fasting insulin levels (p=0.034; 11.4±8.3 vs. 7.9±9.9 μIU/ml), low density lipoprotein (p=0.005; 114.7±31.2 vs. 104.9±28.9 mg/dl), as well as a reduction in carotid-femoral pulse wave velocity (p=0.016; 7.4±2.2 vs. 6.7±1.1 m/s), systolic (p=0.001; 131.6±17.5 vs. 125.7±14.2 mmHg) and diastolic blood pressure (p=006; 84.7±11.1 vs. 80.1±10). There were no significant changes in glucose, triglyceride levels or brachial-artery flow mediated dilation. Conclusion: A personalized, goal directed HP intervention improves abnormalities associated with MetS, including body habitus, lipid and insulin secretion abnormalities, and resulted in significant blood pressure improvements that accompanied decreased central arterial stiffness. These improvements were sustained after two years of follow-up. Whether HP intervention improves long-term outcomes and whether it is cost-effective needs further investigation.
