This cross-sectional survey study examined dieting and exercise variables as a function of parental education in 2,174 male and 1,804 female college-bound high school graduates aged 18 years. Parental education is an index of socioeconomic status (SES). Higher SES was associated with lower current and desired body weight in both women and men. The prevalence of dieting, binging, and vigorous exercise for weight control increased with SES for women but not for men. These data confirm the inverse relationship between body weight, dieting, and social class, previously demonstrated with American adults.
