Exploring the association between perinatal maternal mental health, infant brain development and childhood mental health outcomes - a multi-context s

Lead Research Organisation: King's College London
Department Name: Child and Adolescent Psychiatry

Abstract

During or after pregnancy, up to 20% of women will experience mental health problems, such as depression and
anxiety1
. Poor maternal mental health is likely to affect the care that the infant receives as well as infant-carer
interactions, with profound effects on offspring outcomes, including cognitive, social, behavioural and emotional
development and even psychopathology2-4. Biological changes have also been observed in children of mothers who
experienced perinatal mental health problems, including elevated cortisol reactivity5,6, and structural and functional
alterations in brain regions involved in cognitive-emotional responses to stress, reward sensitivity and socio-emotional
function7-9. Such alterations could contribute to increasing children's vulnerability to developing psychopathology.
This project will evaluate data from typically and atypically developing children (age 2-11 years, n~2000), recruited in
the UK and in Singapore, collected from birth and throughout childhood at different time points. These data include
details of brain structure and function (obtained with magnetic resonance imaging or MRI), perinatal maternal mental
health, psychiatric family history, life events, parenting style, and several aspects of child development including,
motor, language, cognitive, mental health and socio-emotional outcomes.
An increased understanding of how specific brain structural and functional alterations influence the known links
between perinatal maternal mental health and early child development will elucidate the mechanisms underlying the
transgenerational transmission of mental health disorders. Furthermore, the study of long-term effects of maternal
mental health on child cognition and behaviour in diverse geographical settings may inform context-specific
interventions to support maternal mental health and promote child development, as well as facilitate mother-infant
relationships.

To use a whole-brain approach to investigate brain structural and functional connectivity alterations as mediators
between maternal mental ill-health and child vulnerability to developing psychopathology.

Participants will be children assessed as part of large longitudinal studies in the UK and Singapore. These are the
Developing Human Connectome Project (dHCP; http://www.developingconnectome.org/), which followed-up over 1000
infants from birth to age 18 months, the Evaluation of Preterm Imaging study (ePrime), which followed-up 500 children
who were born very preterm (<33 weeks of gestation) at various time points up to age 10, and the Growing Up in
Singapore Towards Healthy Outcomes study (GUSTO; https://www.gusto.sg), which investigated 1200 mothers and
children and followed-up 500 participants up to ten time-points up to the age of 10. These studies have collected
comparable data on MRI imaging at birth (dHCP, ePRIME, GUSTO) and in childhood (ePRIME, GUSTO), perinatal
maternal mental health (e.g., Edinburgh Prenatal Depression Scale), psychiatric family history, life events, parenting
style, and child development including gross and fine motor, language, cognitive, behavioural and socio-emotional
outcomes.
