Abstract

Aims: Serum triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio is known to be associated with cardiometabolic diseases. This study is aimed to evaluate the association between the TG/HDL-C ratio and incident type 2 diabetes with a large-sample, community-based Korean cohort over 12 years. Methods: Among 10,038 participants, a total of 8655 participants aged 40 to 69 years without diabetes were selected from the Korean Genome and Epidemiology Study (KoGES). The baseline TG/HDL-C ratio was divided into quartiles. Newly developed type 2 diabetes was defined by any of the following: a fasting plasma glucose level ≥ 126 mg/dL; a glucose level ≥ 200 mg/dL 2-hours after a 75 g oral glucose tolerance test; an HbA1c ≥ 6.5%; or treatment with anti-diabetic therapy. The hazard ratios (HRs) with 95% confidence intervals (CIs) for incident type 2 diabetes were calculated using multivariate Cox proportional hazards regression models after adjusting for potentially confounding variables. Results: During the 12-year follow-up period, type 2 diabetes developed in 1437 subjects (16.6%, 1437/8655), with incidence rate of 2.8–5.0 (over 2 years). Compared to the reference first quartile, the HRs (95% CIs) of incident type 2 diabetes in the second, third, and fourth quartiles increased in a dose-response manner after adjusting for potentially confounding variables. Conclusions: High TG/HDL-C ratio at baseline may be a useful surrogate indicator of future incident type 2 diabetes.
