During Estonia's anti-alcohol campaign, alcohol-positive suicides significantly decreased, particularly at higher blood alcohol concentrations (BAC). However, the study couldn't definitively link reduced alcohol use to the overall drop in suicide rates.

Area of Science:

  • Public Health
  • Epidemiology
  • Forensic Medicine

Background:

  • The Soviet Union implemented a major anti-alcohol campaign starting June 1, 1985.
  • Estonia experienced significant reductions in both suicide rates and per capita alcohol consumption during this period.
  • Understanding the relationship between alcohol consumption and suicide is crucial for public health interventions.

Purpose of the Study:

  • To examine blood alcohol concentration (BAC) in suicide cases.
  • To assess the impact of the Soviet anti-alcohol campaign on suicide rates and alcohol consumption in Estonia.
  • To investigate the association between alcohol use and suicide mortality.

Main Methods:

  • Analysis of 5054 suicide cases (1981-1992) using official autopsy reports.

  • Categorization of cases by gender and blood alcohol concentration (BAC) levels.
  • Comparison of suicide data before, during, and after the anti-alcohol campaign.

    • Main Results:

    • Per capita alcohol consumption in Estonia fell from 10.9 to 6.6 liters during the campaign.
    • The proportion of alcohol-positive suicides decreased by 39.2% for males and 41.4% for females.
    • The most substantial decrease in alcohol-positive suicides occurred at BAC levels of 2.5 per thousand and above.

    Conclusions:

    • Alcohol consumption is a common factor preceding suicide.
    • Rigorous alcohol restrictions were associated with a notable decrease in BAC-positive suicide mortality.
    • The study design, while observational, suggests a link but does not definitively prove causation between reduced alcohol use and lower suicide rates.
