Background. Against a backdrop of increasing research, clinical and
taxonomic attention in non-suicidal self-injury (NSSI), evidence
suggests a link between NSSI and eating disorders (ED). The frequency
estimates of NSSI in ED vary widely. Little is known about the sources
of this variation, and no meta-analysis has quantified the association
between ED and NSSI.
Method. Using random-effects meta-analyses, meta-regression analyses,
and 1816-6466 unique participants with various ED, we estimated the
weighted average percentage of individuals with ED, those with anorexia
nervosa (AN) and those with bulimia nervosa (BN) who are reported to
have a lifetime history of NSSI across studies. We further examined
predictors of NSSI in ED.
Results. The weighted average percentage of patients with a lifetime
history of NSSI was 27.3% [95% confidence interval (CI) 23.8-31.0%]
for ED, 21.8% (95% CI 18.5-25.6%) for AN, and 32.7% (95% CI
26.9-39.1%) for BN. The difference between BN and AN was statistically
significant [odds ratio (OR) 1.77, 95% CI 1.14-2.77, p = 0.013]. The
odds of NSSI increased by 24% for every 10% increase in the percentage
of participants with histories of suicide attempts (OR 1.24, 95% CI
1.04-1.48, p = 0.020) and decreased by 26% for every 10% increase in
the percentage of participants with histories of substance abuse (OR
0.74, 95% CI 0.58-0.95, p = 0.023).
Conclusions. In the specific context of ED, NSSI is highly prevalent and
correlates positively with attempted suicide, urging for NSSI-focused
treatments. A novel finding is that NSSI is potentially antagonized by
substance abuse.
