Excess calorie availability and adult BMI: A cohort analysis of patterns and trends for 156 countries from 1890 to 2015

Publication Type


Current trends in adult obesity threaten global health. Although the implications of changes in diets, lifestyles, and food environments have been examined, the specific role of excess calorie availability (ECA)—understood as calorie availability in excess of human requirements for a healthy life—and the cohort mechanisms that underlie trends in adult body mass index (BMI) are poorly understood. We examine these relationships for 156 countries over the past century using an age-, sex-, and cohort-specific approach.
