Community based lifestyle intervention improves body weight, anthropometric, and fitness parameters

Abstract

Lifestyle modification of nutrition, physical activity and behavior is a proven methodology for weight loss and health improvement. We examined a community based lifestyle intervention (CBLI) program on anthropometric, fitness and biologic outcomes in 41 (2 men, 39 women) overweight and obese (BMI = 32.0 ± 0.5 kg/m2) adults (age 49.3 ± 1.9 years). We hypothesized that CBLI would improve weight loss, body composition, chronic disease risk biomarkers, and fitness levels. Participants were randomly assigned to an 8 week CBLI (n=23) led by a personal fitness trainer and registered dietitian at a local fitness center, or to a control group (n=18) which received one class session at baseline. At 8 weeks, CLBI had increased weight loss (p=.03), total fat loss (p=.0004), trunkal fat loss (p=.006), and improved flexibility (p=.03) compared to controls. CBLI participants reported improved Weight Loss Efficacy scores (p=.04) compared to controls. All participants reduced total cholesterol from baseline (p=.03 and p=.0005, control and CBLI, respectively). As baseline levels were within normal limits, no changes were observed in glucose, insulin or hsCRP. Community based lifestyle intervention is an appropriate format for weight management. This work was supported by the USDA, Grand Forks Park District, and Altru Health System.
