Abstract:
Objective:To explore glucose and lipid metabolism in obese children and its correlation with precocious puberty.Methods:A total of 65 obese children (obese group) and 65 children with normal body weight (control group) who underwent physical examination at the Beijing Luhe Hospital Affiliated to Capital Medical University from March 2021 to March 2023 were retrospectively selected. Glucose and lipid metabolism indexes of the two groups were detected, and precocious puberty was evaluated according to Tanner staging criteria. Spearman test was used to analyze the correlation between glucose and lipid metabolism indexes and precocious puberty. Logistic regression analysis was used to screen the risk factors of precocious puberty in obese children.Results:The levels of fasting blood glucose (FPG), 2-hour postprandial blood glucose(2 h PG), glycosylated hemoglobin (HbA 1c), fasting insulin (FINS), insulin resistance index (HOMA-IR), triacylglycerol (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and uric acid (UA) in the obese group were higher than those in the control group: 5.90(5.50, 6.50) mmol/L vs. 4.90(4.40, 5.30) mmol/L, (8.46 ± 1.38) mmol/L vs. (7.39 ± 0.87) mmol/L, 5.90(5.10, 6.70)% vs. 5.30(4.50, 5.70)%, (10.67 ± 2.46) mU/L vs. (5.14 ± 1.22) mU/L, 2.10(1.90, 2.30) vs. 1.10(1.00, 1.30), (141.95 ± 34.92) mmol/L vs. (95.21 ± 12.40) mmol/L, (153.82 ± 25.44) mmol/L vs. (143.59 ± 18.47) mmol/L, 80.50(72.10, 94.50) mmol/L vs. 65.10(59.30, 69.80) mmol/L, 293.20(271.80, 330.70) μmol/L vs. 250.90(210.80, 286.90) μmol/L; while the level of high-density lipoprotein cholesterol (HDL-C) was lower than that in the control group: 53.70(50.10, 58.00) mmol/L vs. 59.30(56.70, 62.60) mmol/L, there were statistical differences ( P<0.05). The incidence of precocious puberty in boys and girls in the obesity group was higher than those in the control group: 23.68%(9/65) vs. 0; 37.04%(10/65) vs. 7.41%(2/65), there were statistical differences ( P<0.05). The results of the Spearman test showed that the Tanner scores of testis and pubic hair in boys and breast and pubic hair in girls in the obesity group were positively correlated with FPG, 2 h PG, HbA 1c, FINS, HOMA-IR, TG, TC, LDL-C and UA ( P<0.05), and there was a negative correlation with HDL-C ( P<0.05). The results of multivariate Logistic regression analysis showed that increased levels of FPG, HbA 1c, FINS, HOMA-IR, TG, TC and UA were risk factors for precocious puberty in obese children ( OR>1, P<0.05). Conclusions:Obesity is associated with precocious puberty and the disorder of glucose and lipid metabolism is related to precocious puberty.
