ABSTRACT
<p><b>OBJECTIVE</b>To investigate the possible effects and roles of bodyweight on the puberty onset in adolescent girls.</p><p><b>METHODS</b>Totally 288 Chinese female children and adolescent girls aged 5 to 16 were followed up yearly for four consecutive years. The height, bodyweight, fat percentage, sexual characteristics, and the serum levels of leptin and insulin-like growth factor-1 (IGF-1) were studied to analyze the influential factors of puberty onset and age of menarche.</p><p><b>RESULTS</b>The serum level of leptin elevated significantly from age 13 [(9.23 +/- 1.25) microg/L] and reached peak at age 16 [(13.19 +/- 1.45) microg/L]. IGF-1 significantly correlated with the timing of puberty onset (r = 0.292, P = 0.016). BMI and fat percentage had no significant effects on the onset of puberty, but were negatively correlated with the age of menarche (r = -0.323, P = 0.037, r = -0.298, P = 0.038 respectively).</p><p><b>CONCLUSION</b>Bodyweight may have effect on puberty onset in female adolescents.</p>
