PURPOSE: To examine longitudinal risk factors and short-term risk correlates for the development of extreme forms of restrictive eating among adolescent dieters.
METHODS: Data from Project Eating and Activity in Teens and Young Adults, a population-based study of 2,516 students aged 12-18 years, were collected in 1998-1999 (Time 1) and 5 years later (Time 2). Within this sample, 243 adolescents who reported dieting but not engaging in disordered forms of restrictive eating (e.g., fasting, skipping meals) at Time 1 were followed to determine the self-reported psychological, familial, and social variables predicting initiation of disordered restrictive eating at Time 2. To investigate short-term risk correlates of initiating disordered restrictive eating, the same risk factors were also compared cross-sectionally at Time 2 between the dieters who had and had not initiated disordered restrictive eating. Poisson regression models with robust standard errors were fit for each predictor adjusted for covariates.
RESULTS: Depressive symptoms and low self-esteem were significantly associated with the initiation of disordered restrictive eating in both longitudinal and cross-sectional analyses. Poor family communication/caring and maternal dieting significantly predicted long-term risk for escalating restrictive eating severity; whereas, individual body image issues (i.e., weight concerns, body dissatisfaction) and social concerns (i.e., weight-related teasing, peer dieting) were significant short-term correlates of initiating disordered restrictive eating.
CONCLUSIONS: Depressive symptoms and low self-esteem may be especially important targets for risk identification and prevention for disordered restrictive eating. Intervening on family influences may decrease long-term risk, whereas intervening on body image and responses to social influences may decrease short-term risk for disordered restrictive eating.
