Abstract

In the menopausal transition (MT), combined oral contraceptive (COC) should be chosen accordingly to its neutrality on liver metabolism and to its ability to counter the increase of fat mass (FM) that occurs in this reproductive period of life. This prospective multi-centric observational study was conducted on 36 women in their MT at the Universities of Cagliari, Modena and Naples. The body weight (BW), the Body Mass Index (BMI), the waist to hip ratio (WHR), the measurement of body composition (BC) with the Multi-frequency Bioelectrical Impedance (MF-BIA) were performed before, at the 6th and at the 12th month of the study in which a group of women (control group; N.18) did not assume COC, whereas the other 18 women assumed the four-phasic COC containing estradiol valerate (EV) associated with dienogest (EV/DNG group). In comparison to controls in the EV/DNG group, a significant decrease (p < 0.05) of BW (58.8 ± 7.6 to 57.3 ± 7.0), BMI (24.1 ± 2.7 to 23.5 ± 2.8), WHR (0.82 ± 0.052 to 0.79 ± 0.048) and FM (17.7 ± 5.4 to 16.4 ± 5.6) was observed. In controls, FM significantly increased (17.0 ± 11 to 17.7 ± 2.7; p < 0.05). In conclusion, these results suggest that the anti-androgenic and progestinic activities of DNG associated with a weak estrogenic activity of EV, is a contraceptive method capable of counteracting the negative changes of BC occurring in the MT.
