Ogden CL, Fryar CD, Martin CB, et al. - Using data from the National Health and Nutrition Examination Survey (NHANES), researchers sought to determine the trends, stratified by race and Hispanic origin, in high weight for length, obesity, and severe obesity in the US from 1999 to 2018. In the analytic sample, 92,759 nonpregnant persons with measured weight and length or height were included. Between 1999-2000 and 2017-2018, children younger than 6 years exhibited no significant trends in high weight for length or obesity. Overall, adolescents had increase in obesity, driven primarily by increases in non-Hispanic Black and Mexican American youth. Adult men and women had raise in obesity and severe obesity, with no change in obesity among non-Hispanic Black men after 2005-2006 and a more rapid raise in Mexican American than in non-Hispanic White men.
