Downloaded from 1 2 3 Abstract 4 Objectives: This study explored whether listening to music during pregnancy is longitudinally 5 6 associated with lower symptoms of postnatal depression and higher wellbeing in mothers postbirth. 7 8 9 Design: Prospective cohort study. 10 11 12 Participants: We analysed data from 395 new mothers aged over 18 who provided data in the third 13 trimester of pregnancy and 3 and 6 months later (0-3 and 4-6 months post birth). 14 15 16 Primary and secondaryFor outcome peer measures: Listeningreview to music was only categorised as ‘rarely; a couple of 17 18 times a week; every day <1hr; every day 1-2hrs; every day 3-5hrs; every day 5+hrs’. Postnatal 19 depression was measured using the Edinburgh Postnatal Depression Scale (EPDS), and wellbeing was 20 21 measured using the Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS). Multivariate 22 linear regression analyses were carried out to explore the effects of listening to music during 23 24 pregnancy on depression and wellbeing post birth, adjusted for baseline mental health and potential 25 confounding variables. Sensitivity analyses stratified by baseline mental health and used inverse 26 27 probability weighting to account for differential non-response. 28 29 30 Results: Listening during pregnancy is associated with higher levels of wellbeing (β=0.40, SE=0.15, 31 95%CI 0.10 to 0.70) and reduced symptoms of postnatal depression (β=-0.39, SE=0.19, 95%CI -0.76 32 http://bmjopen.bmj.com/ to -0.03) in the first 3 months postbirth. However, effects disappear by 4-6 months post-birth. These 33 34 results appear to be particularly found amongst women with lower levels of wellbeing and high levels 35 of depression at baseline and amongst those with a history of mental health conditions. 36 37 38 Conclusions: Listening to music could be recommended as a way of supporting mental health and 39 40 wellbeing in pregnant women; in particular those who demonstrate low wellbeing or symptoms of on September 25, 2021 by guest.

Downloaded from 1 2 3 Introduction 4 Perinatal mental health problems affect around 20% of women at some point during the perinatal 5 6 period (1). In terms of conditions characterised by negative symptomology, postnatal depression 7 (PND) is one of the most common problems, and is a debilitating condition characterised by fatigue, 8 9 irritability, insomnia and anhedonia; symptoms which in 25% of affected women last for at least one 10 year (2). Over the last two decades, there has been significant research into the effects of PND on 11 12 mother and infant as well as attention paid to how it can be prevented or managed (3,4). However, in 13 terms of conditions relating more to the absence of positive symptomology, such as low hedonic or 14 15 eudemonic wellbeing, there has been much less research. The few studies that do exist have found 16 that negative mood,For as indicated peer by the Edinburgh review Postnatal Depression only Scale, has a correlation of 17 18 just -0.46 with positive experiences of motherhood (5). This suggests that, as in the wider population, 19 depression and wellbeing are separate constructs in the context of perinatal mental health and a 20 21 positive perinatal experience is more than simply the inversion of negative mood (6). Building on this, 22 women even without PND have been found to demonstrate impairments in emotional problems and 23 24 vitality, suggesting that even in the absence of depression mothers can have impaired wellbeing (7). In 25 light of this, a review has argued that psychological wellbeing defined as a multidimensional 26 27 construct should be an integral part of maternity care (8), and a more recent construct analysis has 28 highlighted the importance not just of identifying PND but also of identifying women with sub- 29 30 optimal perinatal wellbeing and supporting them to achieve positive psychological functioning (9). 31 32 http://bmjopen.bmj.com/ In seeking to support the perinatal mental health of women, the pregnancy period has been 33 34 highlighted as critical.
