Effects of Drospirenone only pill contraception on postpartum mood disorders: A prospective, comparative pilot study.

Objective: The aim of this non-randomized control study was to assess the effect of Drospirenone (DRSP) only pill (DOP) 4 mg, in a 24 active/4 placebo regimen, on the mood of postpartum women who wanted to use a hormonal contraceptive.

Study Design: Seventy-one women in the study group, and 78 in the control group, were included in intention-to-treat analyses. The depression score was assessed using the self-administrated Edinburgh Postnatal Depression Scale (EPDS) at the childbirth preparation course (T0), and at 2 (T1), 12 (T2), and 24 (T3) weeks postpartum follow-ups.

Results: From T0 to T1 an increase in the scores was observed in both groups: in the study group from 9.2 ± 2.5 to 10.1 ± 2.4 (p = 0.02), and in the control group from 8.7 ± 2.7 to 10.3 ± 2.2 (p < 0.001). At the T2 follow-up, the EPDS score reduction was statistically significant in the study group (p < 0.001) but not in the control group (p = 0.16). Similarly, at the T3 follow-up, the score was statistically reduced in the study (p < 0.01), but not in the control group (p = 0.35). The intergroup statistical analysis showed no differences between groups at T0 (p = 0.19) and at T1 (p = 0.55). Instead, they were statistically significant at T2 and T3 (p < 0.001). EPDS scores had no significant correlation with the mode of delivery (r = 0.2; p > 0.05) and with the mode of breastfeeding (r = 0.3; p > 0.05). On the other hand, EPDS scores demonstrated a positive correlation with the social status of single (r = 0.99; p < 0.002) and low education level (r = 0.82; p < 0.004).

Conclusion: Postpartum mood disorders may have persistent effects that compromise the mother's health and newborn development. DRSP, used as DOP, could modulate mood disorders of the postpartum period in women with individual sensitivity to steroid levels.
