ARTICLE HIGHLIGHTS
Research background
β-cell dysfunction and insulin resistance are two crucial factors in the pathogenesis of type 2 diabetes mellitus (T2DM), but the effects may vary with ages, sexes, and ethnicities.
Research motivation
The study of the association β-cell function and insulin resistance with pediatric T2DM is still scarce.
Research objectives
To investigate the association of β-cell function and insulin resistance with pediatric T2DM among Chinese children and adolescents.
Research methods
We applied a multicenter cross-sectional study in China between 2017 to 2019, including 161 children and adolescents with newly diagnosed T2DM, and 1935 healthy control subjects. Homeostasis models (HOMAs) were used to evaluate β-cell function and insulin resistance, and HOMA index were standardized for sex and age.
Research results
The decrease in homeostasis model assessment of β-cell function (HOMA2-%B) z-score and the increase in homeostasis model assessment of insulin resistance (HOMA2-IR) z-score were associated with a higher risk of T2DM, and the decrease in HOMA2-%B z-score always had higher odd ratios than the increase in HOMA2-IR z-score after adjusting for confounding factors.
Research conclusions
β-cell dysfunction, compared with insulin resistance, is a stronger risk factor associated with pediatric T2DM among Chinese children, regardless of obesity status.
Research perspectives
Future cohort studies with larger samples and mechanism researches would help to better understand the specific pathogenesis of T2DM among Chinese children.
