Denmark decreased its tax on spirits by 45% on 1 October 2003. Shortly thereafter, on 1 January 2004, Sweden increased its import quotas of privately imported alcohol, allowing travellers to bring in much larger amounts of alcohol from other European Union countries. Although these changes were assumed to increase alcohol-related harm in Sweden, particularly among people living close to Denmark, analyses based on survey data collected before and after these changes have not supported this assumption.
The present article tests whether alcohol-related harm in southern Sweden was affected by these changes by analysing other indicators of alcohol-related harm, e.g. harm recorded in different kinds of registers.
Interrupted time-series analysis was performed with monthly data on cases of hospitalization due to acute alcohol poisoning, number of reported violent assaults and drunk driving for the years 2000–07 in southern Sweden using the northern parts of Sweden as a control and additionally controlling for two earlier major changes in quotas.
The findings were not consistent with respect to whether alcohol-related harm increased in southern Sweden after the decrease in Danish spirits tax and the increase in Swedish alcohol import quotas. On the one hand, an increase in acute alcohol poisonings was found, particularly in the 50–69 years age group, on the other hand, no increase was found in violent assaults and drunk driving.
The present results raise important questions about the association between changes in availability and alcohol-related harms. More research using other methodological approaches and data is needed to obtain a comprehensive picture of what actually happened in southern Sweden.
