METHODS: 6163 participants (2635 men; 3528 women) in a 1985 survey among rural residents in Korea aged 55 years and above were followed until 2008. A Cox model was used to calculate HRs of suicide death after adjustment for demographic, socioeconomic and health-related confounders.

RESULTS: 37 men and 24 women died by suicide. Elderly persons who consumed alcohol daily, 70 g alcohol (5 drinks) or more per drinking day, or 210 g alcohol (15 drinks) or more per week had higher suicide mortality (p<0.05), compared with non-drinkers. An increase of one drinking day per week (HR=1.17, 95% CI 1.05 to 1.31), 70 g (5 drinks) additional alcohol intake per drinking day (HR=1.38, 95% CI 1.13 to 1.70), and 140 g (10 drinks) additional alcohol intake per week was associated with a 17%, 38% and 12% higher risk of suicide death, respectively. Women had a higher relative risk of suicide death associated with alcohol consumption, compared with men.

CONCLUSIONS: A greater frequency and amount of usual alcohol consumption was linearly associated with higher suicide death. Given the same amount of alcohol consumption, women might have a higher relative risk of suicide than men. Our findings support 'the lower the better' for alcohol intake, no protective effect of moderate alcohol consumption, and a sex-specific guideline (lower alcohol threshold for women) as actions to prevent suicide death.
