Inception rates of deliberate self-harm among adolescents in West London

Background: Studies have suggested that inception rates of deliberate self-harm among different ethnic group adolescents are broadly similar. Aims: We set out to study the rates of adolescent self-harm over a calendar year in Ealing - part of West London. Methods: All cases of deliberate self-harm presenting to the A&E department and paediatrics were identified and socio-cultural factors studied. Ethnicity was obtained using self-ascription. Results: A total of 76 cases were identified over one year. Using the at risk population as denominator, no differences in inception rates were noted according to ethnicity. Overdoses were the commonest method used for deliberate self-harm. Conclusions: The similarities between the Asian and white adolescents suggest that some common aetiological factors may be at play. The risk factors may be related to gender rather than ethnicity in this age group.
