Researchers published the study covered in this summary on Research Square as a preprint that has not yet been peer reviewed.

Key Takeaways

  • The product of the triglycerides and glucose index (TyG) and waist-to-height ratio (WHtR) accounted for 68.6% of the risk for metabolic syndrome (area under the receiver operating characteristic curve [AUC] of 0.686) in an urban Chinese population followed prospectively for 15 years.

  • The findings suggest that the product of TyG and WHtR is superior to three other similar parameters for predicting the risk of metabolic syndrome in the studied population.

  • TyG-related risk factors that combine obesity measures with TyG index are superior to other parameters for identifying metabolic syndrome in both women and men.

Why This Matters

  • Metabolic syndrome, characterized by abdominal obesity, hypertension, dyslipidemia, abnormal glucose metabolism, or previously diagnosed type 2 diabetes, is associated with increased risk for atherosclerosis and cardiovascular disease.

  • The TyG index, combining fasting plasma glucose and fasting triglycerides, is a potential surrogate marker for insulin resistance, which plays a major role in metabolic syndrome development.

  • Research has recently focused on the predictive value of bundled parameters including the product of the TyG index when combined with waist circumference (TyG-WC), waist-to-height ratio (TyG-WHtR), or waist-to-hip ratio (TyG-WHpR).

Study Design

  • Prospective study of an urban Chinese population in Chengdu, Sichuan province with 363 men and 227 women who underwent serial examinations and completed a risk factor survey in 1992 and again in 2007.  

Key Results

  • After adjustments for age, gender, smoking, drinking, physical exercise, and components of metabolic syndrome, TyG-WHtR was the strongest predictor of metabolic syndrome, with an odds ratio of 5.63 (P < .001).  

  • After adjustments, only TyG-WHtR and TyG-WC significantly predicted metabolic syndrome in both genders, with odds ratios for TyG-WHtR of 9.14 (P < .001) in males versus 3.18 (P = .005) in females.

  • In all participants, TyG-WHtR had the largest AUC for metabolic syndrome detection, at 0.686 (TyG-WHtR accounted for 68.6% of the risk for developing metabolic syndrome), followed by TyG-WC (AUC, 0.660), TyG-WHpR (AUC, 0.564), and TyG-index alone (AUC, 0.556).

Limitations

  • Participants were all from China and may not reflect other populations.

  • Metabolic syndrome is a complex, multifactorial condition with limited practical utility as a diagnostic or management tool.

Disclosures

  • There was no funding for this work.

  • The authors had no disclosures.
