Childhood Sexual Abuse a Risk Factor for the Development of Bulimia

 

Child Childhood Sexual Abuse and Eating Disorders in Females: Findings From the Victorian, Australia Adolescent Health Study

Objective; To examine the relationship between childhood sexual abuse (CSA) before the age of 16 years and later onset of bulimia and anorexia nervosa symptoms in females.

Design; A longitudinal cohort study of adolescents observed from August 1992 to March 2003. The cohort was defined in a 2-stage cluster sample using 44 Australian schools in Victoria.

Participants; A total of 1936 persons participated at least once and were survey again to the age of 24 years, including 999 females. The average age at the start of follow-up was 15 years; and at completion, 24 years.

Self-reported CSA before the age of 16 years was ascertained retrospectively at the age of 24 years.

Results  The incidence of bulimic syndrome during adolescence was

  • 2.5 times higher among those who reported 1 episode of CSA and
  • 4.9 times higher among those who reported 2 or more episodes of CSA,

This when compared with females reporting no episodes, adjusted for age and background factors.

The association persisted after adjusting for possible confounders or mediators measured 6 months earlier, including psychiatric morbidity and dieting behavior. There was little evidence of an association between CSA and partial syndromes of incident anorexia nervosa.

Conclusion; Childhood sexual abuse seems to be a risk factor for the development of bulimic syndromes.
