Resilience to Stress During Pregnancy: Biopsychosocial Mechanisms and Implications for Offspring Emotional and Behavioral Outcomes in Toddlerhood.

Exposure to high levels of stress during pregnancy is a known risk factor for a wide range of offspring outcomes, but little is known about the biopsychosocial factors underlying resilience and recovery from stress during pregnancy. The current study investigated associations between emotional and instrumental support during pregnancy and resilience to stress during pregnancy, including perceived resilience (belief in ability to "bounce back" from adversity) and physiological resilience (ability to physiologically recover quickly after an acute stressor). We further tested whether support and resilience during pregnancy predicted offspring internalizing and externalizing behaviors. Participants included 130 pregnant women (ages 26–28 years; 58% Black, 27% White, 15% Multiracial; 28% receiving public assistance) from a population-based longitudinal study. During pregnancy, participants reported on emotional and instrumental support, current life stressors, and perceived resilience to stress. In addition, heart rate variability was recorded continuously before, during, and after a controlled stress test to measure physiological recovery from stressors. When offspring were 2–3 years of age, mothers reported on children's internalizing and externalizing problems. Results from moderated mediation analyses indicated that emotional, but not instrumental, support was associated with perceived resilience during pregnancy, which predicted lower internalizing and externalizing problems in offspring. Emotional support also predicted greater physiological recovery during pregnancy, but only for individuals reporting multiple life stressors. Findings suggest that emotional support may influence psychological and physiological responses to stress during pregnancy, with implications for offspring emotional and behavioral health. Clinical implications of these results and directions for future research are discussed. Public Significance Statement: This study investigated the role of emotional and instrumental support in promoting resilience to stress during pregnancy. Findings suggest that emotional support may positively influence a person's ability to "bounce back" and recover from life stressors during pregnancy, which may have protective effects for children's early emotional and behavioral development. These results highlight the importance of providing accessible care and emotional support to pregnant people to help mitigate the intergenerational effects of stress and promote positive outcomes for parents and their children.
