title: Ethnicity, socio-economic status and self-harm in Swedish youth: a national cohort study.
abstract: BACKGROUND
  Previous studies have shown an elevated risk for self-harm in adolescents from ethnic minorities. However, potential contributions to this risk from socio-economic factors have rarely been addressed. The main aim of this article was to investigate any such effects.
  
  
  METHODS
  A national cohort of 1009 157 children born during 1973-1982 was followed prospectively from 1991 to 2002 in Swedish national registers. Multivariate Cox analyses of proportional hazards were used to estimate the relative risk of hospital admission for self-harm. Parental country/region of birth was used as proxy for ethnicity.
  
  
  RESULTS
  Youth with two parents born outside Sweden (except those from Southern Europe) had higher age- and gender-adjusted hazard ratios (HRs) of self-harm than the majority population (HR 1.6-2.3). The HRs decreased for all immigrant groups when socio-economic factors were accounted for but remained significantly higher for immigrants from Finland and Western countries and for youth with one Swedish-born and one foreign-born parent.
  
  
  CONCLUSIONS
  Socio-economic factors explain much of the variation by parental country of birth of hospital admissions for self-harm in youth in Sweden.
