Body composition in lean women with polycystic ovary syndrome: effect of ethinyl estradiol and drospirenone combination.

Abstract

BACKGROUND:

Limited data are available regarding the potential effects of oral contraceptives (OCs) on body fat distribution particularly in lean women with polycystic ovary syndrome (PCOS). In the current study, we aimed to evaluate the influence of ethinyl estradiol and drospirenone on body composition.

STUDY DESIGN:

Participants included 28 lean patients with PCOS and 28 age- and body mass index (BMI)-matched healthy women. The PCOS patients received ethinyl estradiol 30 mcg/drospirenone 3 mg for 6 months. Body composition parameters were assessed by bioelectrical impedance analysis. Serum androgens, lipids, insulin resistance and glucose metabolism measures were also determined.

RESULTS:

At baseline, the PCOS patients and controls had similar body composition, lipids, insulin resistance and glucose metabolism parameters. Total and trunk fat percentages were negatively correlated with sex hormone binding globulin and were positively correlated with homeostatic model assessment of insulin resistance and free androgen index in the PCOS group.. After 6 months of treatment in the PCOS patients, total fat percentage increased from 24.5%±7.1% to 26.0%±6.1% (p=.035) and trunk fat percentage increased from 20.2%±8.9% to 22.2%±7.1% (p=.014), although weight, BMI and waist to hip ratio (WHR) remained unchanged.

CONCLUSION:

Lean women with PCOS have similar body composition compared to healthy women. OC therapy for 6 months in PCOS patients results in an increased total and trunk fat percentage despite no change in clinical anthropometric measures including weight, BMI and WHR.
