When the definition of self-harm was expanded to include head-banging, scratching oneself, and hitting oneself along with cutting and burning, 32% of the sample said they had done this. In Ireland, a study found that instances of hospital-treated self-harm were much higher in city and urban districts, than in rural settings. The CASE (Child & Adolescent Self-harm in Europe) study suggests that the life-time risk of self-injury is ~1:7 for women and ~1:25 for men. Gender differences
In general, the latest aggregated research has found no difference in the prevalence of self-harm between men and women. This is in contrast to past research which indicated that up to four times as many females as males have direct experience of self-harm. However, caution is needed in seeing self-harm as a greater problem for females, since males may engage in different forms of self-harm (e.g., hitting themselves) which could be easier to hide or explained as the result of different circumstances. Hence, there remain widely opposing views as to whether the gender paradox is a real phenomenon, or merely the artifact of bias in data collection.The WHO/EURO Multicentre Study of Suicide, established in 1989, demonstrated that, for each age group, the female rate of self-harm exceeded that of the males, with the highest rate among females in the 13–24 age group and the highest rate among males in the 12–34 age group.
