We found that both FAP and RAP patients drank at moderate-to-heavy levels regularly, with modest day-to-day variation (intraclass correlation of drinks/day 67%-82%). Alcohol consumption increased 2 days preceding the onset of the index pancreatitis attack as compared to the week prior. Stratifying by prior AP history, heavy drinking in the hazard period was associated with RAP (OR = 3.79, 95% confidence interval [CI] 1.57-9.12). Each drink was associated with 1.22-fold (95%CI 1.10-1.35) increased odds of RAP. Short-term heavy drinking was not associated with a FAP (OR = 1.06, 95%CI 0.43-2.57).</p><p><strong>Conclusion: </strong>In summary, we found that patients with a prior history of AP face a higher risk of RAP due to excess drinking. Drinking intensity did not increase prior to a FAP, which may have been triggered by other cofactors warranting further examination.</p>","PeriodicalId":72145,"journal":{"name":"Alcohol (Hanover, York County, Pa.)","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
