Participants
Details of the Raine Study have been published previously.33 In brief, Raine Study families were recruited from the antenatal booking clinics at King Edward Memorial Hospital for women (KEMH), the only public maternity hospital in western Australia, between May 1989 and November 1991.33 Women with sufficient proficiency in English to understand the implications of participation, an expectation to deliver their baby at KEMH, and an intention to remain in western Australia were invited to take
Preliminary Analyses
The process for classifying eating disorder cases is outlined in Figure 1. Eating disorder cases included individuals who met self-report criteria for DSM-IV AN or BN, or an EDNOS for which proposed diagnostic criteria exist (BED and “EDNOS purging type”). Criteria for EDNOS purging type were taken from Keel et al.43 and were identical to those for BN with the exception that objective binge eating was not present. Thus, the EDNOS purging group included the participants who reported self-induced
Discussion
This study aimed to identify prospective predictors of eating disorders in a population-based control sample of early adolescents, using previously collected longitudinal data. The participants were drawn from the Western Australian Pregnancy Cohort (Raine) Study, and 6% met full or partial criteria for a DSM-IV eating disorder. A further 3% were found to be at risk for developing an eating disorder. These percentages are comparable to those found in previous studies,2, 7 including studies
