Age was compared across body mass index groups by using analysis of variance; categorical variables were compared by using the χ 2 test. When comparing categorical variables across groups, the variables were dichotomized as follows: sex (male versus female); race (white non-Hispanic versus all other races); marital status (married/living as married versus all other categories); education (4-year college graduate or graduate degree versus all other categories); and employment (employed/self-employed versus all other categories).
