Abstract P199: Keep Moving, Your Health Depends On It: Impact Of Improved Physical Activity And Weight Loss In A Wellness Program
Negative impact of CVD as the leading cause of death in the US is worsened by the significant burden of obesity and associated morbidity and concerns about the growing population inactivity. The American Heart Association has emphasized worksite-based interventions to improve CV health. We evaluated the benefits of improved physical activity(PA) and weight loss(WL) among employees of the Baptist Health South Florida enrolled in a wellness intervention program.
Methods: Employees with two or more Cardio-metabolic risk factors , such as total cholesterol ≥ 200 mg/dl, systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg, hemoglobin A1C ≥ 6.5%, and body mass index (BMI) ≥ 30 were enrolled in an intervention program themed “My unlimited potential”. Interventions were focused on diet and PA modifications. We defined improved physical activity as the difference in the metabolic equivalents (METs) at 12 weeks follow-up and at baseline. WL (lbs) was the difference in weight at follow-up. The relationship between WL and changes in METs was explored in an ordered logistic regression.
Results: Overall 203 (48±10 years, 78% females) employees were enrolled with a retention rate of 89% (n=181) at 12 weeks follow-up. At baseline the median weights was 211 lbs., and mean METs- 8.6, while at follow-up the median weight was 200 lbs, and the mean METs 11. At 12 weeks follow up 38% had significant WL (lost >5% of baseline weight). The median WL was 8.4 (IQR 4.8-13.0) lbs and the mean change in METs was 2.4±1.8. Median WL increased with increasing tertiles of METs change; tertile1- 6.5(4-11) lbs., tertile2- 9(6-13)lbs. tertile3- 11(7-15)lbs. Increased PA was related to increased WL across BMI categories adjusting for age, gender and baseline weight.
Conclusion: This study points strongly toward the benefit of increasing PA among other lifestyle modification interventions in controlling weight. Although further follow-up of this population to evaluate sustainability of change is needed, our results clearly relate improved PA and health.
