Association between prenatal maternal depression, prenatal maternal anxiety and child cognitive development measured by the Bayley Scales of Infant Development III Screening Test. Each line plot depicts the mean difference and their CI for child cognitive development (x-axis) for each prenatal maternal mental health group (y-axis). Either no prenatal maternal depression and state anxiety or no prenatal maternal depression and trait anxiety were the reference groups. Models were adjusted for sex, gestational age at birth, age at follow-up, prenatal maternal alcohol use, prenatal maternal tobacco use, maternal employment status at delivery, maternal educational attainment at delivery, parity and the household crowding index.
