Abstract

Purpose

The prevalence of obstructive sleep apnea syndrome (OSAS) is clearly increased in adults with polycystic ovarian syndrome (PCOS), whereas OSAS does not seem to be frequent in adolescents with PCOS, pointing towards the fact that some patients with PCOS develop OSAS in the further course of the disease. We therefore aimed to analyze the changes of polysomnographic variables in obese adolescents with PCOS in a longitudinal analysis.

Methods

Fifteen adolescents with PCOS (age 15.3 years ± 1.2, BMI 32.9 kg/m2 ± 6.4, SDS-BMI 2.5 ± 0.8) underwent overnight 12-channel polysomnography at baseline and after a mean duration of 28 ± 6 months (age 17.8 years ± 1.1, BMI 32.7 kg/m2 ± 7.0, SDS-BMI 2.1 ± 0.9). After performing the initial polysomnography, we treated hyperandrogenemia and insulin resistance in the study group. We determined parameters of body weight/body composition, parameters of glucose metabolism, and serum androgens in all patients at baseline and follow-up. At follow-up, we compared the polysomnographic variables of the study group to those of healthy female adults.

Results

The polysomnographic variables, the parameters of body weight/body composition, and the parameters of glucose metabolism in the study group did not change significantly during the observation period. The serum levels of total testosterone and sex hormone binding globulin increased significantly, whereas free androgen index decreased significantly. At follow-up, the polysomnographic variables of the study group did not differ from those of healthy female adults.

Conclusions

OSAS does not seem to develop in adolescents with PCOS being treated for hyperandrogenism and insulin resistance. The pathogenesis of OSAS in PCOS needs to be examined in larger controlled studies.
