Could listening to music during pregnancy be protective against postnatal depression and poor wellbeing post birth? Longitudinal associations from a preliminary prospective cohort study

OBJECTIVES: This study explored whether listening to music during pregnancy is longitudinally associated with lower symptoms of postnatal depression and higher well-being in mothers post birth. DESIGN: Prospective cohort study. PARTICIPANTS: We analysed data from 395 new mothers aged over 18 who provided data in the third trimester of pregnancy and 3 and 6 months later (0-3 and 4-6 months post birth). PRIMARY AND SECONDARY OUTCOME MEASURES: Postnatal depression was measured using the Edinburgh Postnatal Depression Scale, and well-being was measured using the Short Warwick-Edinburgh Mental Well-being Scale. Our exposure was listening to music and was categorised as 'rarely; a couple of times a week; every day <1 hour; every day 1-2 hours; every day 3-5 hours; every day 5+hrs'. Multivariable linear regression analyses were carried out to explore the effects of listening to music during pregnancy on depression and well-being post birth, adjusted for baseline mental health and potential confounding variables. RESULTS: Listening during pregnancy is associated with higher levels of well-being (β=0.40, SE=0.15, 95% CI 0.10 to 0.70) and reduced symptoms of postnatal depression (β=-0.39, SE=0.19, 95% CI -0.76 to -0.03) in the first 3 months post birth. However, effects disappear by 4-6 months post birth. These results appear to be particularly found among women with lower levels of well-being and high levels of depression at baseline. CONCLUSIONS: Listening to music could be recommended as a way of supporting mental health and well-being in pregnant women, in particular those who demonstrate low well-being or symptoms of postnatal depression.
