The prevalence of suicide attempts and associated risk factors such as sociodemographic conditions, emotional/behavioural problems and parent-child relationships were examined among 591 indigenous Sami and 2100 majority adolescents in Arctic Norway. There were no significant ethnic differences in prevalence of suicide attempts. In both ethnic groups, suicidal ideation, anxious/depressed problems and eating behaviour problems were associated with suicide attempts. Cross-cultural differences in risk factors associated with suicide attempts existed. For Sami adolescents, factors diverging from the traditional cultural norms were associated with suicide attempts, such as alcohol intoxication, single-parent home and paternal overprotection (p</=.05). Vocational studies, not living together with parents, current smoking and experienced sexual intercourse were ethnic specific risk factors associated with suicide attempts among majority peers (p</=.05). Clinicians should take into account that risk factors can differ between ethnic groups and should be sensitive to culturally divergent behaviour.
