Social support as a differential moderator of the association between optimism, birth satisfaction, and postpartum acute stress symptoms of fathers and mothers.

OBJECTIVE: Childbirth can be a stressful event that leads to the development of acute stress. However, little is known about postpartum acute stress among mothers and even less among fathers. The current study aims to expand the understanding of postpartum acute stress symptoms by examining associations with dispositional optimism, subjective birth satisfaction, and social support in a moderated-mediation model. METHOD: Participants comprised 567 mothers and 109 fathers who gave/were present at birth, sampled at the maternity ward of a tertiary healthcare center. Self-report questionnaires were distributed a few days postpartum: demographic and obstetric information, dispositional optimism (Life Orientation Test-Revised), birth satisfaction (Birth Satisfaction Scale-Revised), social support (the Multidimensional Scale of Perceived Social Support), and acute stress symptoms (National Stressful Events Survey Acute Stress Disorder Short Scale). RESULTS: For mothers, birth satisfaction mediated the association between dispositional optimism and acute stress, and social support moderated the association between birth satisfaction and acute stress for all levels of social support (B = .14, SE = .05, CI [.05 to .23]). For fathers, a similar moderated-mediation occurred; however, at high levels of social support, the association between birth satisfaction and acute stress became insignificant (B = .17, SE = .08, CI [.02 to .32]; index of moderated-mediation = .08, [-.07 to .22]). CONCLUSIONS: Optimism through birth satisfaction may reduce acute stress levels following childbirth among parents, while different effects of social support for fathers and mothers were discovered. For fathers, high levels of social support were found to eliminate the association between birth satisfaction and acute stress and therefore buffer the development of postpartum acute stress symptoms. This study took place in one healthcare center with mostly Jewish participants; further studies are thus needed for better generalization.

Association between prior vaginal birth after cesarean and subsequent labor outcome.

OBJECTIVE: To estimate the effect of prior successful vaginal birth after cesarean (VBAC) on the rate of uterine rupture and delivery outcome in women undergoing labor after cesarean. METHODS: A retrospective cohort study of all women attempting labor after cesarean delivery in a university-affiliated tertiary-hospital (2007-2014) was conducted. Study group included women attempting vaginal delivery with a history of cesarean delivery and at least one prior VBAC. Control group included women attempting first vaginal delivery following cesarean delivery. Primary outcome was defined as the rate of uterine rupture. Secondary outcomes were delivery and maternal outcomes. RESULTS: Of 62,463 deliveries during the study period, 3256 met inclusion criteria. One thousand two hundred and eleven women had VBAC prior to the index labor and 2045 underwent their first labor after cesarean. Women in the study group had a significantly lower rate of uterine rupture 9 (0.7%) in respect to control 33 (1.6%), p = .036, and had a higher rate of successful vaginal birth (96 vs. 84.9%, p < .001). In multivariate analysis, previous VBAC was associated with decreased risk of uterine rupture (OR = 0.46, 95% CI 0.21-0.97, p = .04). CONCLUSIONS: In women attempting labor after cesarean, prior VBAC appears to be associated with lower rate of uterine rupture and higher rate of successful vaginal birth.
