OBJECTIVE: This study analyzed the changes in blood glucose and lipid metabolism levels in children with central precocious puberty (CPP) and the correlation between CPP and obesity.
METHODS: In total, 88 children with CPP aged 6-10 years who were admitted to our hospital between January 2023 and June 2024 (the CPP group), and 88 children without CPP in the same age group who received health check-ups (the non-CPP group) were retrospectively enrolled in this study. General data [gender, age, bone age, and body mass index (BMI)] were collected. Levels of blood glucose metabolism indicators [fasting plasma glucose (FPG), 2-h postprandial blood glucose (2hPG), and hemoglobin A1c (HbA1c)] and blood lipid metabolism indicators [triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] were compared. The incidence of obesity was calculated, and the Tanner stages of the obese group and the non-obese group were compared. The correlation between CPP degree (measured by Tanner staging) and obesity degree (measured by BMI) was analyzed using Spearman's correlation analysis.
RESULTS: The differences in gender and age between the CPP and non-CPP groups were insignificant (P > 0.05). Bone age and BMI in the CPP group were higher than in the non-CPP group (P < 0.05). The CPP group had higher serum FPG, 2hPG, HbA1c, TG, TC, and LDL-C levels and lower serum HDL-C levels than the non-CPP group. The incidence of obesity was higher in the CPP group (21.59%, 19/88) than in the non-CPP group (6.82%, 6/88). The Tanner staging scores in the obese group for the boys (testes and pubic hair), girls (breasts and pubic hair), and as a whole (testes/breasts and pubic hair) were elevated compared to those in the non-obese group (P < 0.05). Spearman's correlation showed that the CPP degree (measured by Tanner staging) was positively correlated with the obesity degree (measured by BMI) in boys, girls, and the study sample as a whole (P < 0.001).
CONCLUSION: Children with CPP had abnormal levels of blood glucose and lipid metabolism, and the CPP degree in these children was positively correlated with the degree of obesity.
