1579-P: Prevalence and Incidence of Obesity and Diabetes in the United States, 2011-2017

Recent studies in the U.S. have shown that incidence of diagnosed diabetes decreased and prevalence plateaued after 2010 despite a modest increase in obesity prevalence. If the reduction in diabetes incidence is driven by changing obesity levels, prevalence may be an inadequate metric. Therefore, we investigated changes in prevalence and incidence of obesity and diabetes in adults in the United States during a 17 year period, 2001-2017. We analyzed adult (≥20years) anthropometric records and diabetes status (prediabetes and diabetes combined) from the U.S. national representative Panel Study of Income Dynamics, 2001-2017. We used Poisson models to estimate the prevalence biannually from 2001-2017 and incidence of obesity (cases/1000 person years, PY) over 4 periods (2001-2005; 2005-2009; 2009-2013; 2013-2017). All rates were age- and sex-adjusted; survey weights were applied. Prevalence of obesity increased from 20.9% (95% CI, 19.4-22.5) in 2001 to 26.4 (95% CI, 25.0-27.8) in 2009 to 29.5% (95% CI, 28.1-31.0) in 2017 (p
