Does overweight during a baby's physical examination lead to precocious puberty

Baby's overweight during physical examination may increase the probability of precocious puberty. The occurrence of precocious puberty is related to multiple factors, and overweight may indirectly promote precocious puberty by affecting hormone levels, but it is not the only determining factor. Overweight children have more adipose tissue in their bodies, and adipocytes can secrete hormones such as leptin, which may stimulate the early activation of the hypothalamic pituitary gonadal axis. Obesity may also lead to insulin resistance and elevated levels of insulin-like growth factor, which may accelerate gonadal development. Clinical observations have found that overweight girls are relatively more likely to experience breast development and early menarche. Some overweight children did not experience precocious puberty, indicating that genetic and environmental factors are equally important. Certain genetic mutations may simultaneously lead to obesity and precocious puberty. Exposure to environmental endocrine disruptors such as bisphenol A may also affect developmental processes independently of body weight. In addition, pathological factors such as central nervous system tumors and adrenal diseases may directly induce precocious puberty.

It is recommended that parents regularly monitor their children's height and weight changes, and record the development of secondary sexual characteristics. Daily high sugar and high-fat diet should be controlled to ensure 60 minutes of moderate to high-intensity exercise. If breast development occurs in girls before the age of 8 or testicular enlargement occurs in boys before the age of 9, timely medical attention should be sought from a pediatric endocrinology department. Doctors may evaluate developmental status through methods such as bone age testing and hormone level measurement, and may intervene with drugs such as gonadotropin-releasing hormone analogs if necessary.
