Abstract P235: Baseline Demographic Characteristics of the Million Veteran Program: Increasing BMI Seen From 2011-2016 Among US Male Enrollees
Background: More than one-third of US adults are obese and the prevalence has remained stable since 2003. In the largest cohort of 515,912 men and women participating in the Million Veteran Program (MVP), we analyzed trends in baseline weight/obesity across the years of enrollment.
Objective: The goal of this study is to examine prevalence and trends in baseline characteristics among US Veterans enrolled in MVP between 2011 and 2016. We highlight the trends in BMI over the enrollment period.
Methods: BMI was computed for 479,521 Veterans who enrolled in MVP between 2011 to September 2016. Participants reported weight and height on the baseline survey. Missing survey data was supplemented with patient EMR data taken closest to enrollment date and stratified by year of enrollment.
Results: Mean age was 61.2 (SD=13.8), 91.6% (391,124/427,187) were men, 73.8% (353,720/479,520) White, 18.8% (90,020/479,520) Black, and 7.4% (35,593/479,520) Hispanic. Overall, mean BMI was 29.7 [range 11.3 to 78.5]. Prevalence of underweight, normal weight, and overweight was 0.7% (3,164/479,521), 19.4% (93,318/479,521), 38.4% (184,625/479,521), respectively, in this cohort. While the prevalence of obesity increased with consecutive years of enrollment in men and overall, we did not observe such trend for other categories of adiposity (Fig). When stratified by race we did not observe any difference in prevalence of underweight and normal weight among White and Black participants. Prevalence of obesity was higher in Blacks, but the rate of obesity among Whites appears to be growing at a faster rate than in Blacks. Compared to the general VHA (Veterans Health Administration) population, prevalence of obesity and the distributions of race, gender, and ethnicity were similar among participants in MVP.
Conclusion: Our data show that the prevalence of overweight/obesity is high among US Veterans. Across consecutive years of enrollment, prevalence of obesity but not overweight appears to increase across each ethnic group.
