Background: Social support is associated with decreased symptoms of postpartum mood and anxiety disorders (PMAD) in mothers of healthy infants, but less is known about social support and PMADs in mothers with preterm infants. The purpose of this study was to examine the relationship between social support and symptoms of PMADs reported by mothers in the months following hospital discharge of their preterm infant.
Methods: Mothers of infants less than 33 weeks gestational age were enrolled from neonatal intensive care units (NICU) at 6 sites. Mothers completed PMAD measures of depression, anxiety and post-traumatic stress approximately 3 months following their infant's discharge. Multivariable regression was used to evaluate relationships between social support and PMAD measures.
Results: Of 129 mothers, 1 in 5 reported clinically significant PMAD symptoms of: depression (24%), anxiety (19%), and post-traumatic stress (20%). Social support was strongly inversely associated with all 3 PMADs. Social support explained between 21% and 26% of the variance in depression, anxiety and post-traumatic stress symptoms.
Conclusion: Increased social support may buffer PMAD symptoms in mothers of preterm infants after discharge. Research is needed to determine effective screening and interventions aimed at promoting social support for all parents during and following their infant's hospitalisation.
