Jp. Kelly et al., ALCOHOL-CONSUMPTION AND THE RISK OF MAJOR UPPER GASTROINTESTINAL-BLEEDING, The American journal of gastroenterology, 90(7), 1995, pp. 1058-1064
Objective: To examine the association between current alcohol consumpt
ion and major upper gastrointestinal bleeding, Methods: In a case-cont
rol study in the United States, Sweden, and Hungary, 1004 incident cas
es with upper gastrointestinal bleeding without predisposing factors w
ere compared with 2446 controls, Relative risks for categories of alco
hol consumption (based on the number of drinks currently consumed/wk)
were estimated using logistic regression; the potential confounding ef
fects of cigarettes, nonsteroidal anti-inflammatory drugs, and other f
actors were controlled simultaneously. Results: Compared with drinkers
of < one drink/wk, the relative risks among other current drinkers ra
nged from 0.8 for 1-6 drinks/wk to 6.3 for greater than or equal to 35
drinks; the trend was statistically significant (p < 0.001). A signif
icantly increased relative risk was seen for the heaviest consumption
category within various subgroups: gastric and duodenal hemorrhage; ma
les and females; age <60 yr and greater than or equal to 60 yr; and th
ose who consumed beer, wine, liquor, or a combination of beverages, Co
nclusions: These findings provide evidence that consumption of alcohol
increases the risk of major gastric and duodenal bleeding in nonpredi
sposed individuals.
