Objective: To examine the relation between different
types of alcoholic drinks and upper digestive tract cancers
(oropharyngeal and oesophageal).
Design: Population based study with baseline
assessment of intake of beer, wine, and spirits, smoking habits,
educational level, and 2-19 years' follow up on risk of upper
digestive tract cancer.
Setting: Denmark.
Subjects: 15 117 men and 13 063 women aged 20 to 98 years.
Main outcome measure: Number and time of
identification of incident upper digestive tract cancer during follow
up.
Results: During a mean follow up of 13.5 years, 156 subjects developed upper digestive tract cancer. Compared with
non-drinkers (drinkers of <1 drink/week), subjects who drank 7-21 beers or spirits a week but no wine were at a risk of 3.0 (95%
confidence interval 1.5 to 6.1), whereas those who had the same total
alcohol intake but with wine as
30% of their intake had a risk of
0.5 (0.2 to 1.4). Drinkers of >21 beers and spirits but no wine had a
relative risk of 5.2 (2.7 to 10.2) compared with non-drinkers, whereas
those who drank the same amount, but included wine in their alcohol
intake, had a relative risk of 1.7 (0.6 to 4.4).
Conclusion: A moderate intake of wine probably does
not increase the risk of upper digestive tract cancer, whereas a
moderate intake of beer or spirits increases the risk considerably.
