Risk of suicide among female adolescents with eating disorders: a longitudinal population-based study

Suicide is a major cause of death among individuals with eating disorders. This study examined risk of suicide among females with eating disorders based on population-based military data.

Data on diagnoses of eating disorders from the pre-induction screening for psychopathology and diagnoses assigned during military service were merged with data on later suicide from the nationwide Israeli Death Registry. We identified 1,356 females with eating disorders and compared their risk of suicide to a population-based control group of females without eating disorders over a mean follow-up period of 8.5 ± 5.34 years.

Females with eating disorders had a higher rate of suicide (0.22 %, n = 3) compared to females without eating disorders (0.03 %, n = 166). Having a moderate-severe eating disorder was associated with increased risk of suicide (RR = 12.50, 95 % CI = 3.86-38.09), whereas none of the females diagnosed as having a mild eating disorder died by suicide.

Females with moderate-severe eating disorders are at risk of suicide and should be monitored for suicidal intent.
