Abstract
This study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9-17.9 years of age). Weight, height, and waist circumference were measured and body mass index (BMI) was calculated. A biochemical study was performed to determine the cardiometabolic risk index (CMRI). Blood pressure was evaluated and pubertal stage was assessed with the Tanner criteria. Hierarchical multiple regression analyses were performed. The most significant variable (p < 0.05) in the prognosis of cardiometabolic risk was found to be the BMI in both boys and girls. In the case of girls, the pubertal stage was also a CMRI predictive factor. In conclusion, BMI was an important indicator of cardiovascular risk in both sexes. Pubertal stage was associated with cardiovascular risk only in the girls.Entities:

p value testing the statistical significance of the association between each of the cardiometabolic risk factors and pubertal stage. CMRI, cardiometabolic risk index. CMRI = z-WC + z-triglycerides + z-HDL-C + z-glucose + z-SBP + z-DBP. The HDL-C value was then multiplied by −1, as it is inversely related to cardiovascular risk. We used a lineal chi-square test (χ2) for n (%). a Analyzed by ANOVA one-way (p for trend); b Analyzed by ANCOVA model adjusted by age.

ZBMI: Body mass index (BMI) z-score; B: Unstandardized regression coefficient; SE: Standard error; p: p-value testing the significance of the regression coefficient; R2: Variance explained by the regression model-adjusted values; p (∆F): p-value testing the significance of F change from the preceding model (model 1 includes only the intercept term); ref: reference group of the categorical variable analyzed by creating dummy variables; a CMRI = z-WC + z-triglycerides + z-HDL-C + z-glucose + z-SBP + z-DBP. The HDL-C value was then multiplied by −1, as it is inversely related to cardiovascular risk; b CMRI includes all components of risk score (a) except waist circumference (WC).
