Beverage specific effects on suicide

Abstract

Thor Norström & Ingeborg Rossow: Beverage specific effects on suicide

The authors analyze the relationship between suicide and beverage specific indicators of alcohol sales in Norway and Sweden. The data comprised aggregate time series for Norway (1918–1994) and Sweden (1948–1994). The suicide indicator was the number of male suicides per 100,000 inhabitants (15+). The beverage specific indicators were sales of beer, spirits and wine (liters 100 % ethanol per inhabitant, 15+). The beverage specific effects on suicide were estimated by means of ARIMA-models. For Norway as well as Sweden, there was a statistically significant relationship between suicide on the one hand, and sales of beer (in Sweden retail sales only) and spirits on the other. A common finding in the two countries was the absence of any effect of wine sales. A tentative interpretation of the findings is that spirits and beer sales are markers of the prevalence of an important risk group for suicide, i.e., heavy drinkers. The fact that beer seems to be of greater importance in this context in Norway – which might be attributable to differences between the two countries in the availability of this beverage – is a reminder of how culturally bounded the findings are.
