The adaptive psychological changes of elective induction of labor in breastfeeding women

Abstract Background Labor induction has been associated with breastfeeding suppression, but reasons for why this association exists have not been well determined. Methods We examined the influence of elective labor induction by vaginal prostaglandin at gestational week 41 + 3  days on affective, cognitive, and behavioural adaptations early in puerperium and on breastfeeding pattern at 1 and 3 months. Results One hundred and eighty consecutive puerperae were assigned to two groups: mothers having received vaginal prostaglandin E2 gel (Prepidil®, dinoprostone) before labor (PGE group, n  = 90) and mothers having received no treatment (unmedicated group, n  = 90). The day of discharge mothers completed the Edinburg Postnatal Depression Scale, (EPDS), State and Trait Anxiety Inventory (STAI-Y), and Mother to-Infant Bonding Scale (MIBS). Later they participated in telephone interviews concerning their breastfeeding practices at 1 and 3 months, which were classified according to WHO definitions. When compared with unmedicated, PGE group puerperae scored [median, (IQR)] significantly higher EPDS [9 (7–13) vs 5 (3–8), p 0.003], STAI-state [46 (39–51) vs 39 (34–48), p 0.002], STAI-trait [39 (36–48) vs 34 (32–45), p 0.04], and MIBS [10 (5.25–10) vs 5 (3–4), p 0.002] scores. In addition, while the breastfeeding practices were similar at hospital discharge, at follow-up the labor induced mothers were less likely to maintain full breastfeeding with respect to untreated mothers: 1 month (p 0.001); and 3 months (p 0.003). Conclusion We present evidence that elective induction of labor by prostaglandins at gestational week 41 + 3  days is associated with reduced exclusive breastfeeding rates at 1 and 3 months after discharge and higher EPDS, STAI, and MIBS scores.
