Resumen breve

Obesity is a disorder associated with metabolic dysfunction and changes in cardiovascular risk markers; the use of oral contraceptives (OCs) may exert a further negative effect on these alterations in patients with PCOS.

To assess the effects on arterial function and structure and hemostatic parameters using an levonorgestrel intrauterine device (IUS-LNG) in women with obesity

A randomized controlled clinical trial.

Descripción detallada

Setting: Academic hospital.

88 women between 18 and 40 years of age with obesity (BMI between 20 and 40 kg/m2)randomized to use IUS-LNG or Copper-IUD for 12 months

Exclusion criteria: category 3 and 4 Medical Eligibility Criteria for IUD-Cu and IUS-LNG - WHO-2010, pregnancy, lactation, concomitant drugs, smoking.

Main Outcome Measures: Brachial artery flow-mediated vasodilation, carotid intima-media thickness and the carotid artery stiffness index were evaluated at baseline and after 6 and 12 months. Serum markers of cardiovascular disease and hemostatic parameters will be also analyzed.
