* Discrepancy = (self-reported weight) – (measured weight) † Percentages may not sum to 100 due to rounding ‡ Figures in parentheses are standard errors §Adjusted for race-ethnicity, highest educational attainment, and BMI category. For males, additional covariates included cigarette smoking in the past and desire to lose weight. For females, additional covariates included marital status, annual income, level of activity, and time since last visit to a health professional.
