Exploring the relationship between timing of menarche and eating disorder symptoms in black and white adolescent girls

Objective: This study examined the relationship between timing of sexual ma turation and eating disorders symptoms in adolescent girls. Method: Data we re collected over 10 years for a cohort of 1,213 Black girls and 1,166 Whit e girls who were either 9 or 10 years old at study entry. Annually, girls' height and weight were measured and, biannually, girls completed self-repor t measures of eating disorders symptoms. Results: Early-onset menarche is a risk factor for the development of body image and dieting concerns, but th e effect of timing is due to the impact of early and late maturation on bod y weight. Discussion: Findings underscore the importance of adiposity as a risk factor for poor mental health. (C) 2001 by John Wiley & Sons, Inc.
