Association of maternal postpartum depression symptoms with infant neurodevelopment and gut microbiota

Introduction

Understanding the mechanisms underlying maternal postpartum depression (PPD) and its effects on offspring development is crucial. However, research on the association between maternal PPD, gut microbiota, and offspring neurodevelopment remains limited. This study aimed to examine the association of maternal PPD symptoms with early gut microbiome, gut metabolome, and neurodevelopment in infants at 6 months.

Methods

Maternal PPD symptoms were assessed using the Edinburgh Postpartum Depression Scale (EPDS) at 42 days postpartum. Infants stool samples collected at 42 days after birth were analyzed using 16S rRNA sequencing and liquid chromatography-mass spectrometry (LC-MS) detection. Infant neurodevelopment was measured at 6 months using the Ages and Stages Questionnaire, Third Edition (ASQ-3). Correlations between gut microbiota, metabolites and neurodevelopment were identified through co-occurrence network analysis. Finally, mediation analyses were conducted to determine potential causal pathways.

Results

A total of 101 mother-infant dyads were included in the final analysis. Infants born to mothers with PPD symptoms at 42 days postpartum had lower neurodevelopmental scores at 6 months. These infants also had increased alpha diversity of gut microbiota and were abundant in Veillonella and Finegoldia, while depleted abundance of Bifidobacterium, Dialister, Cronobacter and Megasphaera. Furthermore, alterations were observed in metabolite levels linked to the Alanine, aspartate, and glutamate metabolic pathway, primarily characterized by decreases in N-Acetyl-L-aspartic acid, L-Aspartic acid, and L-Asparagine. Co-occurrence network and mediation analyses revealed that N-Acetyl-L-aspartic acid and L-Aspartic acid levels mediated the relationship between maternal PPD symptoms and the development of infant problem-solving skills.

Conclusions

Maternal PPD symptoms are associated with alterations in the gut microbiota and neurodevelopment in infants. This study provides new insights into potential early intervention for infants whose mother experienced PPD. Further research is warranted to elucidate the biological mechanisms underlying these associations.

Efficacy of the integrative Body-Mind-Spirit group intervention for improving quality of life in parent-child dyads adjusting to atopic dermatitis: protocol for a randomised controlled trial

INTRODUCTION

Atopic dermatitis (AD) is the most common childhood inflammatory skin problem affecting 15%-30% of children. Although AD adversely impacts the psychosocial well-being of children and their parent caregivers, parents' psychosocial well-being is seldom mentioned in most non-pharmacological education programmes. A family-based psychosocial intervention, Integrative Body-Mind-Spirit (I-BMS) intervention, is examined. This study compares the efficacy of two versions of the I-BMS intervention (one delivered to both parents and children; one delivered to parents only) with a health education active control (delivered to parents only) in promoting adaptive emotional regulation and quality of life of children with AD and their parent caregivers.

METHODS AND ANALYSIS

This is a three-arm, with equal randomisation, parallel randomised controlled trial. 192 parent-child dyads will be recruited through hospitals and non-governmental organisations in Hong Kong. Each dyad will complete an individual pre-group screening interview. Eligible dyads will be randomised in a ratio of 1:1:1 into one of the three arms. Each arm consists of six weekly sessions. A computer-generated list of random numbers will be used to perform randomisation. The primary outcomes are quality of life and emotional regulation. Assessments are administered at baseline, post-intervention and 6-week follow-up. Mixed factorial Analysis of Covariance (ANCOVAs) based on intention-to-treat principle will be conducted to examine the efficacy of the two I-BMS interventions. Structural equation modelling will be conducted to examine the parent-child interdependent effects of intervention.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Human Research Ethics Committee of the University of Hong Kong (EA2001001) and the Institutional Review Board of the Hospital Authority of Hong Kong (UW 21-400, KC/KE-20-0360/FR-2, NTEC-2021-0408). Consent will be sought from participating parents and children. Parental consent for child participants will also be obtained. Findings will be presented in peer-reviewed journals and at conferences in medical dermatology, paediatrics and social work.
