Schmöker A, et al. - In the present study, the researchers compared experiences of stress in mothers and fathers of preterm infants during the first year of life, evaluated changes in parental stress and investigated potential predictors of parental stress. Information on parental stress was gathered at 8 weeks after discharge and at 6 and 12 months postpartum from 493 mothers and 329 fathers of 547 preterm infants between 2013 and 2015 in Sweden. According to results, mothers perceived more role restriction and fathers more social isolation at the three-time points. Stress reduced in mothers during the first year, on the other hand, stress increased in fathers between 6 and 12 months. During the first year after birth, mothers of very preterm infants, parents of twins and parents with lower perceived general health reported higher stress levels.
