Introduction

Suicide takes a great toll on both individuals and societies. Successful preventive measures would require a careful understanding of the scope of suicidal ideation as well as its associated factors. Amongst mental disorders, anorexia nervosa has the highest mortality rate due to suicide.

Objective and aims

Studying the prevalence of suicidal ideation and its associated factors in adolescents (13–19 years old) affected by disordered eating (DE).

Methods

Logistic regression was employed to study associations between suicidal ideation and age, gender and disordered eating in adolescents from a population-based prospective study, The Young-HUNT 3 cohort, 2006-8. DE cases were defined using the self-reported questionnaire (Eating Attitude Test-7) and then grouped into two subscales, poor appetite/under-eating and uncontrolled appetite/overeating.

Results

A total of 3933(boys 49% and 51% girls) were included. In total, 177 poor appetite/under-eating and 365 uncontrolled appetite/overeating cases were identified. Prevalence of suicidal ideation was 24.5% in total sample with girls being more affected (27.1%). Prevalence of suicidal ideation amongst poor appetite/under-eating case group and uncontrolled appetite/overeating cases was respectively 43.5 and 39.2%. The odds-ratio of suicidal ideation amongst poor appetite/under-eating cases compared to control group was 2.56 (95% CI, 1.85 to 3.42, P-value < 0.001) whilst the odds-ratio of suicidal ideation amongst uncontrolled appetite/overeating cases compared to control group was 2.19 (95% CI, 1.75 to 2.74, P-value < 0.001). Results remained significant after adjusting for anxiety and depression symptoms.

Conclusion

Focus on high risk groups such as DE seems important in taking suicide preventive measures.
