Lifetime Drinking History of Persons With Chronic Pancreatitis.

Cumulative consumption of alcohol and variations of alcohol intake by age are unknown in chronic pancreatitis (CP) patients in North America. This study summarizes the lifetime drinking history (LDH) by physician attribution of alcohol etiology, smoking status and sex in persons with CP. We analyzed data on 193 CP participants who completed the LDH questionnaire in the North American Pancreatitis Continuation and Validation Study (NAPS2-CV). We collected data on frequency of drinking and drinks per drinking day for each drinking phase of their lives. We examined differences in total number of alcoholic drinks and weight of ethanol consumed by physician's assessment of CP etiology, sex and smoking status. We also compared intensity of drinking in 20, 30 and 40s by timing of CP diagnosis. Persons diagnosed with alcoholic CP consumed median of 34,488 drinks (interquartile range 18,240-75,024) prior to diagnosis of CP, which occurred earlier than in persons with CP of other etiology (47 vs. 52 years). Cumulative drinking was greater in male vs. female patients. Male CP patients with a diagnosis of CP before the age of 45 drank more intensely in their 20s as compared to those with later onset of disease. Current smoking was prevalent (67%) among those diagnosed with alcoholic CP. Twenty-eight percent of patients without physician attribution of alcohol etiology reported drinking heavily in the past. Lifetime cumulative consumption of alcohol and prevalence of current smoking are high in persons diagnosed with alcoholic pancreatitis. Intense drinking in early years is associated with earlier manifestation of the disease.
