The correlation between insulin resistance and blood lipids in children.

BACKGROUND

This work focused on the correlation between insulin resistance (IR) and blood lipids (BL) in children with simple obesity, as well as the intervention effects of high-intensity interval training (HIIT) in weight loss in children.

METHODS

80 children aged 6 to 17 years with simple obesity were selected from our hospital and randomly grouped into two groups. Children in the control (Ctrl) group underwent traditional moderate-intensity continuous training (MICT), while those in the other group received HIIT (HIIT group). After four weeks, body composition-related indicators, BL levels, and IR were measured.

RESULTS

After exercise, children in both groups possessed obvious reductions in body mass index (BMI), body fat percentage (BFP), triglyceride (TG), and homeostasis model assessment of IR (HOMA-IR), demonstrating remarkable differences in contrast to those after intervention (P<0.05). The HIIT group also exhibited considerable differences in waist circumference (WC), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) (P<0.05). After exercise, the HIIT group demonstrated more observable BMI, WC, TG, and HOMA-IR reductions, showing great differences with the Ctrl group (P<0.05). HOMA-IR exhibited positive correlations with TC, TG, and HDL-C but a negative one with LDL-C (P<0.05).

CONCLUSIONS

HIIT improved the body composition and BL levels in children with simple obesity, downregulated HOMA-IR, and positively impacted their health status. Furthermore, IR was associated with BL-relevant indicators in children with simple obesity.
