Background: Irisin is a myokine secreted from skeletal muscle that plays an important role in the regulation of adipokine secretion and the differentiation of osteoblast and osteoclasts. Irisin has been shown to increase browning of adipose tissue, thermogenesis, energy expenditure, and insulin sensitivity. The aim of this study was to evaluate the relation of serum irisin level with metabolic, anthropometric parameters and bone mineral density in children and adolescents. Methods: This study included 103 Korean children and adolescents in a single center: 49 (47.6 %) obese participants with a body mass index (BMI) ≥95th percentile and 54 (52.4%) healthy control with BMI 15-85th percentile. Fasting serum irisin was quantitatively assayed by ELISA. Lipid profile, fasting blood glucose, fasting insulin, the homeostasis model assessment of insulin resistance (HOMA-IR), Tryglyceride and glucose (TyG) index, osteocalcin and 25-hydroxyvitamin D3 were measured as metabolic parameters. Bone mineral density (BMD) was performed by dual energy X-ray absorptiometry (DXA) in 33 healthy subjects. Results: Serum irsin was significantly higher in obese group than in control group (mean 18.1 ± 3.5 vs 16.2 ± 2.0ng/mL; P = 0.002). There was no significant difference in serum irisin levels between prepubertal and pubertal subjects. In the all participants, irisin level was positively correlated with height SDS (r = 0.24; P = 0.02), BMI SDS (r = 0.37; P <0.001), HOMA-IR(r = 0.21; P = 0.04) and osteocalcin (r = 0.27; P = 0.006). Serum irisin level was negatively correlated with HDL cholesterol (r = -0.29; P = 0.005) and positively correlated with total body less head (TBLH) Z-score (r = 0.40, P = 0.03). Conclusions: This study showed the association between irisin levels with BMI standard deviation score, HOMA-IR and HDL cholesterol. Our data showed a positive correlation between irisin levels and BMD in healthy subjects. Further studies are needed to clarify the mechanisms by which irisin could affect glucose/lipid metabolism and bone metabolism. Presentation: Thursday, June 15, 2023
