Self-harm and eating disorders are often comorbid in clinical samples but their co-occurrence in the general population is unclear. We assessed the co-occurrence of self-harm and disordered eating behaviours at age 16 and 24 years in 3384 females and 2326 males from a UK population-based cohort. There was substantial overlap at both time points: almost two-thirds of 16-year-old females, and two-in-five 24-year old males who self-harmed also reported disordered eating. Among young people, self-harm may signal the occurrence of disordered eating and vice versa. It is important to screen for both sets of difficulties to provide appropriate treatment.
