Triglyceride Glucose Index Is More Robust Surrogate Biomarker for Predicting Type 2 Diabetes Mellitus Than HOMA-IR in Population Attending Aulaqi Specialized Medical Laboratories, Yemen

Insulin resistance (IR) is an independent risk factor for type 2 diabetes mellitus (T2DM). Because only triglyceride levels and fasting blood glucose are required to measure the triglyceride-glucose (TyG) index, and the insulin test, which is used in the homeostatic model assessment of insulin resistance (HOMA-IR) calculation, is costly and unavailable in the majority of laboratories in the cities of developing countries. Thus, the goal of our study was compared the predictive power of HOMA-IR and the TyG index for assessing IR, as well as the incidence and prevalence of T2DM. Methods: From January 2025 to July 2025, a cross-sectional study was carried out at Aulaqi Specialized Med. Lab. Several risk factors were evaluated among 215 participants, 110 of whom had T2DM and 105 of whom without diabetes. The following analysis data were collected; high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglycerides (TG), fasting blood glucose (FBG), HBA1c, C-peptide, TyG index and HOMA-IR. The results of the statistical test were considered significant if the P value>0.05. Results: The T2DM participants had higher mean TyG index (4.87 ± 0.32 vs. 4.66 ± 0.31, P
