Non-alcoholic fatty liver disease (NAFLD) is recognized as a major cause of liver-related morbidity and mortality. The aim of this study was to examine the longitudinal association between baseline hematocrit (HCT) level and the development of NAFLD in Chinese adults. We performed a prospective cohort study of 2798 healthy Chinese adults without NAFLD at baseline. A Cox proportional hazards model was used to determine hazard ratios for NAFLD incidence in two groups determined by baseline hematocrit levels (group A, HCT <49%; group B, HCT ≥ 49%). During 10346.5 person-years of follow-up, 474 (16.9%) NAFLD cases developed between 2008 and 2012. After adjusting for multiple covariates and change in the covariates during the follow-up period, the hazard ratios (95% confidence interval) for NAFLD incidence when comparing group B with group A were 1.17 (1.03-1.31) and 1.70 (1.26-2.31), respectively (p<0.001).
Conclusions: HCT level may be a predictor of the development of NAFLD in Chinese adults.
