Estimates of energy intake, requirements and imbalances based on anthropometric measurements at global, regional and national levels and for sociodemographic groups: a modelling study

Summary

Estimating total energy intake based on anthropometric measures captures the regional and temporal trends in body weight, height and physical activity. The estimates can be used as a complementary measure to existing proxies of energy intake. Among other things, they can inform misreporting of intake in dietary surveys, uncertainty in the amount of food wasted and the lack of data on at-home production in food availability statistics. Aligning existing measures of food intake with consistent estimates of overall energy intake could improve dietary analyses and policy planning.
