We unravel the absolute level and relative prominence of two demographic processes that are relevant for childhood obesity, and that will ultimately determine the long-term course and pace of change in child obesity rates. We leverage data from the National Health and Nutrition Examination Survey to decompose change in child obesity from 1971 to 2012. We partition change into that attributable to (1) healthier, more nutritionally and economically advantaged cohorts in the population being replaced by cohorts of children who are less advantaged (between-cohort change), and (2) the health habits, nutrition, and social and economic circumstances of all cohorts of …

Trends in adult obesity have been used to motivate key public health policies in the United States. While these analyses provide important insights into the broad historical contours of the obesity epidemic in the U.S., they shed less light on the proximate mechanisms that have generated these changes and that will ultimately determine the long-term course and pace of change in obesity rates. We used data from the National Health and Nutrition Examination Survey (NHANES), Glenn Firebaugh's linear decomposition technique, and Kitagawa's algebraic decomposition method to decompose change in body mass index (BMI), obesity, and morbid obesity from 1971 through …
