dc.description.abstractWhereas significant advances have been made in understanding how exposure to early adversity "gets under the skin" of children to result in long-term changes in developmental outcomes, the processes by which positive social relationships become biologically-embedded remain poorly understood. The aim of this study was to understand the pathways by which maternal and infant social environments become biologically-embedded in infant cortisol reactivity. Two hundred seventy-two pregnant women and their infants were prospectively assessed during pregnancy and at 6 months postpartum. In serial mediation analyses, higher perceived social support from partners during pregnancy was associated with lower infant cortisol reactivity or larger decreases in cortisol in response to a stressor at 6 months of age via lower self-reported prenatal maternal depression and higher mother-infant interaction quality. The findings add to our understanding of how perinatal social relationships become biologically-embedded in child development.en_US
