Background Public health recommendations on the benefits and harms of moderate alcohol intake require a thorough and unbiased understanding of all potential effects of various levels and patterns of alcohol consumption. We seek to evaluate the associations between patterns of current and past alcohol consumption with hospitalizations and mortality. Methods Data came from a prospective cohort of 12,327 adults (56% women, 78% white, mean age 60 years) participating in the Atherosclerosis Risk in Communities study visit 3 (1993 to 1995). Current and past alcohol consumption was based on self‐report. Hospitalizations and mortality were ascertained through December 31, 2017. Negative binomial and Cox proportional hazards regressions were used. Results 24.8% of the study population reported never drinking, 48.3% reported currently drinking without a history of heavy drinking, 4.2% reported currently drinking with a history of heavy drinking, 19.2% reported being former drinkers without a history of heavy drinking, and 3.4% reported being former drinkers with a history of heavy drinking. Compared to those who reported drinking ≤1 to 7 drinks/wk, never drinkers (incident rate ratio [IRR]: 1.21 (95% confidence interval 1.13, 1.29) and former drinkers with (IRR: 1.43 [1.26, 1.63]) or without (IRR: 1.21 [1.13, 1.30]) a history of heavy drinking had a positive association with all‐cause hospitalization ( p < 0.001). Those who reported drinking ≤1 to 7 drinks/wk had the lowest all‐cause mortality rate (19.2 per 1,000 person‐years [18.4, 20.1]) and former drinkers with a history of heavy drinking had the highest (43.7 per 1,000 person‐years [39.0, 49.1]). Conclusions The positive associations with hospitalization and mortality were stronger among never and former drinkers compared to those who consume ≤1 to 7 drinks/wk. Former drinkers with a history of heavy drinking had a stronger positive association with adverse health outcomes than former drinkers without a history of heavy drinking, highlighting the impact of this pattern of alcohol consumption.
