The effects of privatization of alcohol sales in Alberta on suicide mortality rates

We examine the impact of privatization of retail sale of alcohol in Alberta, Canada, between 1985 and 1995 on mortality rates from suicide. Privatization took place in three stages: The opening of privately owned wine stores in 1985, the opening of privately owned cold beer stores and the selling of spirits and wine in hotels in the rural area in 1989–90, and finally privatization of all liquor stores in 1994. Interrupted time series analysis with Auto Regressive Integrated Moving Average (ARIMA) modeling was applied to male and female suicide rates to assess the impact of the three stages of privatization. The analyses demonstrated that most of the privatization events resulted in either temporary or permanent increases in suicide mortality rates. Other alcoholrelated factors, including consumption levels and Alcoholics Anonymous (AA) membership rates, also affected suicide mortality rates. These analyses suggest that privatization in Alberta has acted to increase suicide mortality rates in that province.
