INTRODUCTION: To investigate whether increased intrapancreatic fat deposition (IPFD) heightens the risk of diseases of the exocrine and endocrine pancreas. METHODS: A prospective cohort study was conducted using data from the UK Biobank. IPFD was quantified using MRI and a deep learning–based framework called nnUNet. The prevalence of fatty change of the pancreas (FP) was determined using sex- and age-specific thresholds. Associations between IPFD and pancreatic diseases were assessed with multivariate Cox-proportional hazard model adjusted for age, sex, ethnicity, body mass index, smoking and drinking status, central obesity, hypertension, dyslipidemia, liver fat content, and spleen fat content. RESULTS: Of the 42,599 participants included in the analysis, the prevalence of FP was 17.86%. Elevated IPFD levels were associated with an increased risk of acute pancreatitis (hazard ratio HR per 1 quintile change 1.513, 95% confidence interval CI 1.179–1.941), pancreatic cancer (HR per 1 quintile change 1.365, 95% CI 1.058–1.762) and diabetes mellitus (HR per 1 quintile change 1.221, 95% CI 1.132–1.318). FP was also associated with a higher risk of acute pancreatitis (HR 3.982, 95% CI 2.192–7.234), pancreatic cancer (HR 1.976, 95% CI 1.054–3.704), and diabetes mellitus (HR 1.337, 95% CI 1.122–1.593, P = 0.001). DISCUSSION: FP is a common pancreatic disorder. Fat in the pancreas is an independent risk factor for diseases of both the exocrine pancreas and endocrine pancreas.
