Secular trends and ethnic disparities in the regional differences in prevalence (%) of obesity in US adults, Behavioral Risk Factor Surveillance System (BRFSS) 2011–2016. Secular trends (a) 2011, (b) 2013, (c) 2015, (d) 2016. Ethnic disparities using combined BRFSS 2014-2016 (e) non-Hispanic Whites, (f) non-Hispanic Blacks, (g) Hispanics. BMI of study participants was calculated based on reported weight and height. The improvement changes to the BRFSS affect obesity prevalence estimates, and mean that estimates from data collected in 2010 and before cannot be compared estimates from data collected in 2011 and thereafter. The World Health Organization (WHO) defines obesity as BMI ≥30 kg/m². Data source: Centers for Disease Control and Prevention (CDC).
