Abstract With the increasing prevalence of overweight and obesity in children, the influence of overweight and obesity on pubertal timing has attracted the attention of scholars. This paper reviewed the correlation and mechanism between childhood obesity and pubertal timing, especially for earlier pubertal timing, and found that the regulation of hypothalamic-pituitary-gonadal axis function by nutrition and metabolic signals might under lie those associations. Obesity in girls was positively correlated with early pubertal timing, while the conclusions in boys were inconsistent. Overweight in boys was related to early pubertal timing, obesity in boys could lead to both earlier and later onset of puberty, which warrents further investigation.

With the increasing burden of hypertension in Chinese adults， the detection rate of hypertension among children and adolescents continued to rise， drawing increasing attention to the impact of pubertal timing on blood pressure. In recent years， many scholars have evaluated the association between pubertal development and blood pressure at different stages using various methods of assessing pubertal timing. To understand the correlation between pubertal timing and blood pressure in adolescents， this study reviews the associations between pubertal timing and blood pressure and their underlying mechanisms. The relationship between earlier female pubertal development and the risk of hypertension in adulthood shows positive， negative， and U-shaped correlations， with varying results. Earlier female pubertal development may lead to a higher detection rate of hypertension during adolescence. Most of the studies focus on the correlation between pubertal timing and adult blood pressure， with less research on adolescent blood pressure， indicating a need for further research to reveal underlying patterns.
