Aims: Hemoglobin glycation index (HGI), which quantifies interindividual variations in glycated hemoglobin (HbA1c), is known to be associated with diabetic complications and metabolic diseases. However, information on the association between HGI and nonalcoholic fatty liver disease (NAFLD) in healthy population, especially in Asian population is limited.

Methods: A total of 14,465 subjects without diabetes who underwent liver ultrasonography during routine health examination were enrolled and stratified in quartiles according to HGI levels.

Results: The prevalence of NAFLD significantly increased with HGI quartiles (24.8%, 29.7%, 32.6% and 40.6% in the 1st, 2nd, 3rd, and 4th HGI quartiles, respectively; p-value<0.001). As compared with the lowest HGI quartile group, the highest HGI quartile group had worse metabolic parameters including body weight, waist circumference, body mass index and lipid profiles. In the multiple logistic regression analysis adjusted for multiple factors, the odds ratio of having NAFLD was 1.564 (95% CI: 1.350-1.813, p <0.001) in the highest HGI quartile group.

Conclusions: Elevated HGI levels are independently associated with prevalence of NAFLD in a healthy Asian population.
