Repeated detection of non‐alcoholic fatty liver disease increases the incidence risk of type 2 diabetes in young adults

Aim This study aimed to investigate the effects of repeated detection of non‐alcoholic fatty liver disease (NAFLD) on the incidence risk of type 2 diabetes in young adults. Materials and Methods In this nationwide population‐based observational study using data from the Korean National Health Insurance Service, approximately 1 125 015 young adults aged 20‐39 years who underwent health screening four times between 2009 and 2013 were included. NAFLD was defined as a fatty liver index (FLI) of ≥60. Repeated detection of NAFLD scores was defined as the number of times the participants met the criteria for NAFLD (0‐4). To account for the degree of repeated detection of NAFLD, weighted repeated NAFLD scores were scaled as a sum by assigning points (0 points for FLI
