Stress during pregnancy is associated with developmental outcome in infancy

Animal studies show that prenatal maternal stress may be related to cognitive impairments in offspring. Therefore, we examined whether psychological and endocrinologic measures of stress during human pregnancy predicted developmental outcome of the infant at 3 and 8 months. METHOD: Self-report data about daily hassles and pregnancy-specific anxiety and salivary cortisol levels were collected in 170 nulliparous women in early, mid- and late pregnancy in a prospective design, in which healthy infants born at term were followed up after birth.
