Triglyceride-glucose index in adolescents with type 1 diabetes mellitus

Diabetes Res Clin PractPublished Cross-sectional study

Authors' conclusion

The TyG index is a simple and non-invasive biomarker that could serve as a valuable adjunct to HbA1c monitoring in adolescents with T1DM. It may have a potential utility as a screening tool for early identification of patients at risk for developing metabolic complications such as insulin resistance and dyslipidemia.

Study context

Population
Adolescents with T1D (50% female), paediatric unit of the San Juan Hospital, Alicante (Spain)
Participants
36 adolescents
Outcome
Association of TyG index with glycaemic control

Main finding

As reported in the abstract

Associations of higher TyG index
  • Higher TyG index statistically associated with higher BMI, percentile and z-score
  • Higher TyG index statistically associated with higher TG, HbA1c and glucose levels
  • Higher TyG index statistically associated with TG/HDL, total cholesterol/HDL, TyG-BMI and TyG-waist circumference indexes

Observational data: associations, not effects.
