| Abstract: | AIMS/INTRODUCTION: To investigate whether the Fibrosis-4 index can help stratify the risk of diabetes mellitus in patients with fatty liver disease. MATERIALS AND METHODS: Based on fatty liver disease and Fibrosis-4 index (cut-off value 1.3), we retrospectively divided 9,449 individuals, who underwent at least two annual health checkups, into four groups stratified by sex: normal; high Fibrosis-4 index without fatty liver disease; low Fibrosis-4 index with fatty liver disease; and high Fibrosis-4 index with fatty liver disease. RESULTS: Onset rates for diabetes mellitus in the normal, high Fibrosis-4 index without fatty liver disease, low Fibrosis-4 index with fatty liver disease and high Fibrosis-4 index with fatty liver disease groups were 1.6%, 4.3%, 6.8% and 10.2%, respectively, in men, and 0.6%, 0.9%, 5.3% and 7.0%, respectively, in women. Compared with the normal group, the high Fibrosis-4 index without fatty liver disease, low Fibrosis-4 index with fatty liver disease and high Fibrosis-4 index with fatty liver disease groups were at a significant risk for diabetes mellitus onset in both male and female participants. Furthermore, in both sexes, high Fibrosis-4 index with fatty liver disease remained a significant risk factor on multivariate analysis (high fibrosis-4 index with fatty liver disease group: adjusted hazard ratio 4.03, 95% confidence interval 2.19-7.42 [men] and adjusted hazard ratio 6.40, 95% confidence interval 1.77-23.14 [women]). CONCLUSIONS: Individuals with fatty liver disease and high Fibrosis-4 index had a higher risk of diabetes mellitus onset. Therefore, Fibrosis-4 index can help stratify the risk of diabetes mellitus in patients with fatty liver disease and identify patients requiring intervention. |
