Adolescence is a particularly sensitive period during which self-injury may begin due to societal pressures to fit in with peers and/or general difficulties with family, friends, or school [8, 11].
Self-injury rates vary from province to province, with lower provincial rates among Prince Edward Island (55 per 100,000) and Ontario and Manitoba (58) compared to New Brunswick and Newfoundland and Labrador (81) . Compared to the provinces, self-injury rates are substantially higher in the Yukon (192) and Nunavut (379). According to data from CIHI, individuals from less affluent neighbourhoods have twice the rates of self-injury compared to individuals from affluent neighbourhoods . In more affluent neighbourhoods, parental criticism and youth alienation may be associated with self-injury behaviours .
New forms of social media may provide a manner for women to communicate and compare their self-injury via blogs and videoblogs  which may glamorize self-injury behaviour(s). In one study, 15% of participants stated that their self-injury behaviour was motivated because of television and/or movies .
