The moderating effect of cardiometabolic factors on the association between hepatic and intrapancreatic fat

Abstract Objective Previous studies have investigated the association between hepatic fat and intrapancreatic fat deposition (IPFD); however, results have been inconclusive. The presence of cardiometabolic factors in certain subpopulations could explain this discrepancy. The aim of the present study was to use moderation analyses to determine the conditions under which hepatic fat is associated with IPFD. Methods All participants underwent 3T abdominal magnetic resonance imaging (MRI) and spectroscopy. Hepatic fat and IPFD were manually quantified by independent raters. Moderation analyses were performed with adjustment for sex and ethnicity. Results There were 367 participants included. Adjusted analyses of the overall cohort revealed that age, glycated hemoglobin (HbA 1c ), low‐density lipoprotein cholesterol (LDL‐C), high‐density lipoprotein cholesterol (HDL‐C), and triglycerides were significant moderators ( p 36 mg/dL, and triglycerides < 203 mg/dL. Conclusions The association between hepatic fat and IPFD is generally present in young and middle‐aged adults with good cardiometabolic health, whereas the link between the two fat depots becomes uncoupled in older adults or individuals with cardiometabolic risk factors. image
