Resumen: Objective: To evaluate in a cross-sectional study adiponectin and leptin levels in prepubertal and pubertal daughters of women with PCOS and their relationship to insulin sensitivity and reproductive features. Study design: We studied 92 daughters of PCOS women (PCOSd) and 76 daughters of control women (Cd) matched by age and body mass index SD scores and distributed according to breast Tanner stage: prepuberty (Tanner 1), early puberty (Tanner 2–3) or late puberty (Tanner 4–5). In all girls an oral glucose tolerance test was performed. Leptin, adiponectin, sex steroids, SHBG, glucose, insulin and lipid profile were determined. Leptin–adiponectin ratio, free androgen index and insulin sensitivity (HOMA-IR and ISI composite) were then calculated. Results: Prepubertal PCOSd showed lower serum adiponectin compared to Cd (p = 0.028), whereas during puberty no differences were observed between the groups. Leptin concentrations were similar in both groups in all Tanner stages. In addition, in PCOSd during early puberty, adiponectin showed a negative correlation with testosterone and leptin showed a negative correlation with ISI composite, which were independent of BMI SDS (r = 0.39; p = 0.02 and r = 0.42; p = 0.01). Conclusion: These observations suggest that during the prepubertal period PCOSd exhibit abnormal adiponectin levels, independently of BMI. Moreover, leptin and adiponectin may be related to metabolic and reproductive abnormalities observed in PCOSd during the early stages of sexual development.
