The global prevalence of non-suicidal self-injury is two times higher among adolescent females than males in certain regions, according to a study published in JAMA Network Open.
Non-suicidal self-injury (NSSI) is the deliberate, self-inflicted damage to the body that results in immediate harm without the intention of dying. Previous studies have found that NSSI can strongly predict suicide attempts.
For this study, Dr. Fiona Moloney and colleagues examined the prevalence of non-suicidal self-injury among female and male adolescents in various geographic regions.
The research included 38 studies involving over 266,000 participants from 17 countries, including Asia, North America, Europe, and Australia.
Dr. Moloney and her team searched databases for sex differences in non-suicidal self-injury among adolescents aged 10 to 19. The search covered the period from January 1, 2000, to May 10, 2022.
The study revealed that Non-suicidal self-injury was twice as common among female adolescents compared to male adolescents in North America and Europe but not in Asia. Specifically, the researchers found that the total non-suicidal self-injury across regions was about 21% for girls and 14% for boys. 
In North America, the prevalence of non-suicidal self-injury among adolescents was significantly higher in females than in males (20.2% vs. 8.9%). Similar findings were observed in Europe (19.4% vs. 12.6%) and Australia (18.8% vs. 16.8%). 
However, compared to North America and Europe, the difference in NSSI between genders was less pronounced in Asia, with a slightly higher prevalence among male adolescents than females (24.1% vs. 24.8%).
The researchers added that “future research with sex-, region-, and culture-specific lenses will be essential in clarifying how and why NSSI phenotypes differ by sex in different regions.”
