Suicide in south Tyrol 1980-1992: influence of affiliation to different language groups.

National suicide rates differ widely throughout Europe. The reasons for this are still unclear. Besides differences in actual suicide figures, different assessment methods and certification strategies have been suggested. This study examines the ethnic influence on suicide rates of South Tyrol, an Italian province bordering on Austria. The region has historically been under the cultural influence of both countries, with its population composed of three ethnic groups: the German-, Italian- and Ladinian-language groups. The study shows a significant correlation between the male suicide rate and the proportion of the German-language group. The ethnic suicide rates of Italian- and German-speaking people in South Tyrol were found to approximate each other, in comparison with the national rates for Italy and Austria, as a possible result of cultural interaction.
