Description: Utilizing the National Longitudinal Survey of Children and Youth (NLSCY), this study examined risk factors for binge eating and purging in 12- and 13-year-old girls. The girls who binged and purged were identified from Wave 2 of the NLSCY data collection and followed back to Wave 1 of the data collection when they were 10 and 11 years of age. Measures of pubertal development, body mass, dissatisfaction with appearance, general self-esteem and perceptions of parental discipline and nurturance were examined at 10 and 11 years of age as potential risk factors for binge eating and purging. Measures of parental depression and parental discipline and parental nurturance were also obtained from the person most knowledgeable about the daughter when the child was 10 and 11 years of age. A group of 10- and 11-year-old girls served as a symptom control group. This group of girls did not binge and purge at 12 and 13 years of age but endorsed high anxiety and low mood at 12 and 13 years of age similar to the girls who binged and purged.The results revealed girls who binged and purged were more likely have early puberty and high body mass at 10 and 11 years of age than girls with high anxiety and low mood. After taking into account pubertal development, logistic regression analyses revealed a high body mass at 10 and 11 years of age increased the risk for binge eating and purging at 12 and 13 years of age and this effect was potentiated by low appearance-related self-esteem. In addition, parental depression and inconsistent discipline at 10 and 11 years of age made significant and unique contributions to the prediction of binge eating and purging at 12 and 13 years of age. The model was able to correctly classify 77.5% of the girls into those who subsequently binged and purged and those that did not. The results are discussed in term of the importance of physiological and psychological factors in the development of binge eating and purging. A putative developmental pathway to binge eating and purging is outlined and recommendations made for early prevention programs that focus specifically on the identified risk factors.
