Triglyceride to HDL cholesterol ratio strongly predicts diabetes development within 10 years

The multivariable model was adjusted for sex, age, systolic blood pressure, BMI, smoking status, plasma glucose levels after fasting, and exercise habits. The prediction performance and cut-off values of each indicator were assessed by employing areas under time-dependent receiver operating characteristic (ROC) curves (AUCs). A self-reported history of diabetes, a fasting plasma glucose level of 126 mg/dL, or usage of antidiabetic medicines were used to identify type 2 diabetes.

Based on the study, the researchers reported the following findings:

• During the study, 6,080 people developed T2D. They were followed for a median of 6.0 years.
• Multivariable analysis revealed that the ratio of TG/HDL-C (per unit, HR; 1.03) was substantially linked to the risk of incident T2D.
• AUC and cut-off points for the ratio of TG/HDL-C for T2D development after 10 years were 0.679 and 2.1, respectively.
• The AUC of the ratio of TG/HDL-C was considerably larger compared to that of LDL-C, HDL-C, and TG alone.
• An interaction effect was discovered between BMI, sex, and lipid profiles in subgroup analysis.
• Females and participants having a BMI of < 25 kg/m2 showed a higher correlation between lipid profile levels and T2D onset.

"The findings demonstrate that the ratio of TG/HDL-C was a stronger predictor of type 2 diabetes development within 10 years than LDL-C, HDL-C, or TG," the researchers wrote. "These results indicated the importance of providing future medical care support."
