Among middle aged men in Japan, non-drinkers and regular heavy drinkers are more likely to commit suicide than occasional drinkers.

摘要

Non-drinkers and regular heavy drinkers (>=414 g/week ethanol) had an increased risk of suicide compared with occasional drinkers (non-drinkers: RR 2.3, 95% CI 1.2 to 4.6; regular heavy drinkers: RR 2.3, 95% CI 1.2 to 4.7; see http://www.ebmentalhealth.com/supplemental for absolute suicide rates). Ex-drinkers had an increased risk of suicide compared with occasional drinkers (RR 6.7, 95% CI 1.8 to 25.0), but never drinkers did not (RR 1.7, 95% CI 0.5 to 6.2).
