Abstract

Objective: Eating disorders (EDs) and non-suicidal self-injury (NSSI) are both phenomena with onset in adolescence. Their co-occurrence is associated with higher symptom severity and an elevated risk of suicide. In this meta-analysis, we examine the lifetime prevalence of NSSI in youth with EDs.

Methods: We searched PsycInfo, PubMed and previously published systematic reviews for studies reporting on lifetime NSSI prevalence among children and adolescents (19 years or younger) with an ED (anorexia nervosa, bulimia nervosa, binge eating or other specified feeding and EDs) published until June 2024. A generalized linear mixed model meta-analysis was performed to estimate the pooled prevalence. Meta-regressions and multivariate meta-analyses were conducted to estimate separate prevalence rates based on ED diagnosis and care frame (e.g., inpatient vs. outpatient), respectively.

Results: Fifteen studies comprising 3311 children and adolescents were included. Pooled lifetime NSSI prevalence across all ED diagnoses was 34.2% [CI: 27.5%-41.7%]. Heterogeneity was large (I² = 93.8%). Lifetime NSSI prevalence rates were significantly higher for participants with bulimia nervosa (53.6%) and those with anorexia nervosa binge-eating/purging type (51.9%) than for participants with anorexia nervosa restrictive type (15.8%).

Discussion: The small number of studies and the large heterogeneity limit the conclusiveness of this meta-analysis. Results suggest an even higher prevalence of lifetime NSSI in adolescents with an ED than in adults with an ED. The results support previous findings indicating higher prevalence rates of NSSI for EDs associated with binge eating and purging behaviours than for restrictive EDs.

The journal focuses on implications for best practice in diagnosis and treatment.
