Tobacco smoking and alcohol consumption are established risk factors for diseases of the pancreas. With the recent advances in imaging modalities (such as magnetic resonance (MR) imaging), opportunities have arisen to study pancreas size, in both health and disease. Studies investigating the relationship between tobacco smoking, alcohol consumption, and total pancreas volume (TPV) - a holistic measure of pancreatic exocrine reserve - are lacking. The aim of the present study was to investigate the associations between MR-derived TPV and tobacco smoking/alcohol consumption.This cross-sectional study recruited individuals with a history of pancreatitis and healthy controls. A validated questionnaire was used to ascertain current and lifetime tobacco smoking and alcohol consumption. TPV was quantified using MR images by two independent raters. Generalized additive models and linear regression analyses were conducted and adjusted for demographic, metabolic, and pancreatitis-related factors.A total of 107 individuals following pancreatitis and 38 healthy controls were included. There was no statistically significant difference in TPV between any of the tobacco smoking/alcohol consumption categories of individuals following pancreatitis and healthy controls, in both unadjusted and adjusted analyses. In individuals following pancreatitis, multivariate linear regression found no association between TPV and 7 smoking- and alcohol-related variables. Sensitivity analyses constrained to individuals who did not abstain from either smoking or drinking following their first attack of pancreatitis did not yield statistical significance with TPV. In post-hoc analysis, age was significantly inversely associated with TPV in the most adjusted model (p = 0.016).This is the first study to investigate the association between tobacco smoking, alcohol consumption, and MR-derived TPV following pancreatitis. It appears that age, but not tobacco smoking or alcohol consumption, is associated with a significantly reduced TPV.
