BACKGROUND AND AIMS

In adolescence and obesity, the pathophysiology of polycystic ovary syndrome (PCOS) is very difficult to distinguish. We aimed to assess the diagnosis of PCOS in the population of obese adolescent.

METHODS

Cross-sectional study.

SETTING

PARTICIPANTS

Forty-nine post-menarcheal obese adolescents with mean age of 14.7 years.

INTERVENTIONS

Anthropometric assessment and review of medical records were done. Clinical and laboratory hyperandrogenism were quantified using Ferriman-Gallwey index and androgenic dosages, respectively. Ovarian morphology was evaluated through suprapubic ultrasonography.

RESULTS

By the 2015 Witchel et al. guideline for PCOS in adolescence, 18.4% were diagnosed as having PCOS. When assessed by Rotterdam, Androgen Excess and PCOS Society, and American National Institute of Health criteria's, 26.4%, 22.4%, and 20.4% had PCOS, respectively. Irregular menstrual cycles were found in 65.3% of patients. Clinical hyperandrogenism was observed in 16.3% of girls and 18.4% had elevated serum androgen values. Suprapubic ultrasonography revealed enlarged ovaries in 18.4% of the adolescents.
