Participants self-reported their history of alcohol consumption, including type of alcohol consumed (beer, wine, and/or liquor). One drink was defined as one can, bottle or 12 oz glass of beer, one 4 oz glass of wine, or one shot of liquor because they each contain approximately 14 g of alcohol. The average weekly consumption of beer, wine, and liquor was recorded separately by decade of age, starting in their 20s, i.e., 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, and 80+. Lifetime total alcohol consumption was computed by summing the total number of drinks of beer, wine, and liquor in each decade. Average number of drinks consumed per week in the past decade + current decade; the past two decades + current decade; and the past three decades + current decade also were determined. Participants also were grouped as: never drinkers, exclusive consumers of beer, wine or liquor, and those who consumed two or three types of alcohol. Under the a priori hypothesis that the pattern of alcohol consumption of alcohol might be related to pancreatic cancer, binge alcohol consumption was assessed
