The widespread use of synOT in managed labor warrants caution, as the influence of synOT on a new mother's well-being is evident at 2 months postpartum.
Lower OT levels were found among those who were insecurely attached, and among those who experienced SLE within the last year. In a multiple linear regression, both attachment security and SLE significantly contributed to a model of prenatal OT levels. These individual difference factors explained 38% of the variance in prenatal OT, which may in turn predict poorer maternal mental health and caregiving outcomes during the postpartum period.
Mothers with mood or anxiety disorders exhibit less optimal interactive behavior. The neuropeptide oxytocin (OT) has been linked to more optimal interactive behaviors in mothers without mental illness, and it may play a particularly beneficial role in mothers with mood or anxiety disorders given its antidepressant and anxiolytic functions. We compared the relationship between OT and interactive behavior in mothers with and without mental health problems. Participants included 20 women diagnosed with postpartum mood or anxiety disorders (clinical sample) and 90 women with low levels of depression and anxiety during pregnancy and postpartum (community sample). At 2 months' postpartum, blood was drawn to assess maternal OT levels, and mother-infant interaction was coded for maternal sensitivity, intrusiveness, remoteness, and depressiveness. Clinical mothers exhibited less sensitive, more intrusive, and more depressive interactive behaviors than did community mothers. The groups did not differ in OT levels. Mothers with higher OT levels were less intrusive with their infants. Higher OT levels were associated with less depressive interactive behavior only in clinical mothers. OT was associated with positive interactive behaviors in both groups. In clinical mothers, the calming and soothing effects of OT may promote more relaxed, energetic, and infant-focused interactive behaviors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
