Abstract: Maternal stress in pregnancy exerts powerful programming effects into the next generation. Yet it remains unclear whether and how adversity from other times in the woman's life influences her prenatal stress and her offspring's stress functioning. In a sample of 217 Black American mother-infant dyads, we examined whether different types of maternal stress were differentially related to her infant's stress functioning within the first few months after birth. We prospectively assessed maternal distress (perceived stress, depression, and anxiety) early and late in pregnancy, infant behavioral adaption in the context of a mild stressor at 2 weeks of age, and infant diurnal cortisol at 3-6 months of age. We additionally collected retrospective reports of maternal experiences of lifetime discrimination and childhood adversity. Maternal distress experienced late, but not early, in pregnancy predicted lower infant attention in the context of a stressor. Moreover, lifetime experiences of discrimination indirectly impacted infant attention by increasing maternal distress late in pregnancy. These effects were specific to infant behavioral adaptation and were not related to infant diurnal cortisol levels. However, infant diurnal cortisol levels were associated with maternal experiences of discrimination from prior to pregnancy and adversity from the mother's childhood even after controlling for prenatal distress. Our results underscore the cascading nature of stress across the mother's life span and across generations. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
