Abbreviation: BMI, body mass index.
BMI was calculated as weight in kilograms divided by height in meters squared. Obese was defined as participants with a BMI of 30 or greater.
All of the models for both sexes combined include sex as a covariate.
Models for both sexes, combined for all covariates, include significant interactions between race/Hispanic origin group and educational category, age group and educational category, race/Hispanic origin group and smoking status, race/Hispanic origin group and sex, educational category and sex, and smoking status and sex.
For men, the model includes an interaction between race/Hispanic origin group and smoking status.
For women, the model includes interactions between age group and educational category, race/Hispanic origin group and educational category, age group and smoking status, and race/Hispanic origin group and smoking status.
