Race differences in accuracy of self-reported childhood body size among white and black women.
OBJECTIVE
To assess the relation of self-reported current and recalled preadolescent body size to measured BMI (kilograms per meter squared) and interviewer's assessment of body size.


METHODS
This was a prospective cohort study of 1890 white and black women who were 9 to 10 years old at time of enrollment and were followed up 10 to 13 years later. At baseline, subjects had their weight and height measured and were asked to indicate their current body size from a series of nine pictograms. A sample of the subjects also had their body size evaluated by interviewers. At the young-adult follow-up visit, subjects were asked to recall their body size at 9 and 10 years old and to indicate their current weight, height, body size, and level of concern with weight.


RESULTS
Among the women with interviewer assessments, 84% of the white women and 67% of black women recalled a body size that was within one body size of the interviewer's assessment. Independent of weight status in childhood or at follow-up, black women were 3 times more likely than white women to recall a body figure that was more than one figure leaner than the shape they reported at baseline (odds ratio = 3.5, 95% confidence interval 2.8 to 4.5) or than the interviewer's rating at baseline (odds ratio = 3.4, 95% confidence interval 2.4 to 4.9).


CONCLUSIONS
The results suggest that the use of body figures to recall childhood size are best suited for ranking subjects in terms of BMI. The higher rate of underestimation of size by black women suggests that body figure ratings work best for white women.
