Maternal childhood trauma and perinatal distress predict the development of attention in infants from 6 to 18 months in a Swedish cohort study

Abstract

AbstractMaternal distress is repeatedly reported to have negative impacts on the cognitive development in children. Studies examining the association between maternal distress and the development of attention in infancy are few. This study investigated the longitudinal relationships between maternal distress (depressive symptoms, anxiety symptoms, and exposure to childhood trauma) and the development of attention in infancy in 118 mother-infant dyads. We found that maternal exposure to non-interpersonal traumatic events in childhood and a large degree of anxiety during the 2nd trimester was associated with less attention of the infants to audio-visual stimuli at 6, 10, and 18 months. In addition, exposure to interpersonal traumatic events in childhood was identified as a moderator of the negative effect of maternal anxiety during the 2nd trimester on the development of attention in infants. We discuss the possible mechanisms accounting for these cross-generational effects. Our findings underscore the importance of maternal mental health to the development of attention in infancy and address the need for early screening of maternal mental health during pregnancy.
