چکیده :

This paper proposes a benchmark for comparing SES gradients across countries, based on

gross domestic product apportioned to members of differing wealth categories within

countries. Using this approach, we estimate absolute wealth in 360 populations in 36

developing countries and model its relationship with overweight (BMI 25) among nonpregnant

women ages 18–49. A simple model based on absolute wealth alone strongly

predicts odds of overweight (), a relationship that holds both between countries

and between different groups in the same country (10 populations for each of 36

countries). Moreover, world region modifies this relationship, accounting for an additional

22% of variance (). This allows us to extract a basic pattern: rising rates of

overweight in lower and middle income countries closely track increasing economic

resources, and the shape of that gradient differs by region in systematic ways.
