Abstract/OtherAbstract:
OBJECTIVE: To determine the extent of misreporting of energy intake (EI) and its anthropometric, demographic, and psychosocial correlates in a bi-racial cohort of young women. RESEARCH METHODS AND PROCEDURES: This was a cross-sectional study of 60 black and 60 white young women, 18 to 21 years old, enrolled in a longitudinal study. Total energy expenditure was assessed using doubly labeled water. Self-reported EI was obtained from 3-day food records. BMI was computed from height and weight. Fat mass was assessed by DXA. Multivariate analyses examined racial differences on the extent of misreporting and its effect on other potential correlates of misreporting. Race-specific step-wise linear regression analysis was performed to examine the effect of BMI, parental education, and drive for thinness on misreporting of EI. RESULTS: More white women tended to under-report EI than black women (22% vs. 13%, p = 0.07). In black women, under-reporting was significantly (p = 0.01) associated with drive for thinness score but was only marginally (p = 0.1) associated with BMI. Each point increase in drive for thinness score was associated with under-reporting by 40 kcal/d. In white women, under-reporting was significantly (p = 0.03) associated with higher parental education by 440 kcal/d and also only marginally (p = 0.09) with BMI. DISCUSSION: This tendency for under-reporting of EI limits the use of self-reported EI in studying energy balance in free-living subjects. Most black and almost all white women in their late teens significantly under-reported their EI, whereas under-reporting was not as evident among lean young black women.
