Sex differences in the secular change in waist circumference relative to body mass index in the Americas and England from 1997 to 2020.

ABSTRACT:

Objective

To quantify changes over time in waist circumference (WC) relative to body mass index (BMI) by sex in the Americas (United States of America, Mexico, Chile, Peru) and England.

Methods

Data from adults aged 25-64 years between 1997 and 2020 was analysed; US data was stratified by racial-ethnic groups. Sex-specific BMI and WC means, and obesity and abdominal obesity prevalence, were compared between the first and last surveys. Using data from all survey years, secular changes across the BMI and WC distributions were estimated applying quantile regression models. BMI was added as a predictor of WC to estimate secular changes in WC relative to BMI. Interaction terms were included in all models to evaluate differences by sex.

Results
