Abstract P385: My Unlimited Health Potential: Short term Effect of Participation in a Worksite Lifestyle Intervention Program on Significant Weight Loss and Eligibility Criteria for Bariatric Surgery Among High Risk Individuals
Background: Current recommendations support bariatric surgery among the morbidly obese as an option to mitigate future risk of cardiovascular disease, diabetes and hypertension. To date, there is little evidence on the effect of extensive lifestyle interventions among those high-risk individuals in reducing the need for such procedures.
Methods: The purpose of the present study was to examine the efficacy of an intensive lifestyle workplace intervention on significant body weight and cardiovascular disease risk factors across the spectrum of obesity. Changes in BMI were measured from baseline to 12 week follow up, along with corresponding improvements in cardio-metabolic risk. In addition, the decrease in participants meeting criteria for bariatric surgery over the study period was examined. Bariatric surgery criteria were defined as BMI≥40 or BMI between 35 and 40 and at least one of the following co-morbidities: diabetes, hypertension, or high cholesterol.
Results: The study population consisted of 169 individuals (49±10 years, 77% female) with BMI≥27 at baseline and complete data at follow-up. A total of 65 (39%) participants lost at least 5% of both their initial BMI and body weight. Additionally, 32% dropped an entire BMI category. Of note, 38%(18 of 48) who were classified as BMI>40 were in BMI 35-39 at follow-up, respectively 37%(13 of 55) of individuals in the BMI category 35-39 successfully moved to the BMI category 30-34 at 3 months follow-up. Sixty-three participants (37% of total) initially met criteria for bariatric surgery. At 12 weeks follow-up 35% (22 of 63) of these candidates no longer qualified.
Conclusions: Worksites can be effective for achieving clinically important reductions in body weight and diminish the potential need for procedures among a small proportion of morbidly obese individuals. Further follow-up is needed to ascertain whether weight loss can be sustained long-term, and if the short term gains will translate to significant improvements in cardio-metabolic risk profile.
