Consumption of alcohol and risk of cancer among men: a 30 year cohort study in Lithuania
Studies have indicated hazardous consumption of large quantities of alcohol among adults in Lithuania.
We assessed the associations of alcohol consumption at baseline with cancer incidence among men in a population-based cohort study, using Cox models adjusted for smoking, education and body mass index. Attained age was used as a time-scale. During follow-up (1978–2008) 1,698 men developed cancer.
A higher amount of alcohol consumption (≥140.1 g/week vs. 0.1–10.0 g/week) was positively associated with increased risk of total cancer [hazard ratio (HR) = 1.36, 95 % confidence interval (95 % CI) 1.11, 1.65], upper aerodigestive tract cancer (HR = 2.79, 95 % CI 1.23, 6.34) and alcohol-related cancers (i.e. oral cavity, pharynx, larynx, oesophagus, colorectal and liver cancer) (HR = 1.88, 95 % CI 1.25, 2.85).
Compared to occasional drinkers (a few times/year), drinkers 2–7 times/week showed an increased risk of total (HR = 1.45, 95 % CI 1.16, 1.83), alcohol-related (HR = 1.83 95 % CI 1.14, 2.93) and other cancers (HR = 1.35, 95 % CI 1.04, 1.76).
Our results showed no statistically significant associations between quantity of alcohol intake per one occasion and risk of cancer.
About 13 % of total, 35 % of upper aerodigestive tract, 22 % of alcohol-related and 10 % of other cancer cases were due to alcohol consumption in this cohort of men.
