Insights
This study tested a comprehensive intervention to improve early childhood development in rural Vietnam by addressing maternal nutrition, mental health, parenting, infant health, and violence. The intervention showed promise in reducing cognitive deficits in two-year-olds.
Area of Science:
- Global Health
- Developmental Psychology
- Public Health Interventions
Background:
- Optimal early childhood development is crucial due to rapid growth and lasting impacts of early risks.
- Identifying and mitigating risks during pregnancy and early childhood is an international priority.
- Existing interventions address risks like maternal nutrition, mental health, parenting, infant health, and gender-based violence.
Purpose of the Study:
- To evaluate the effectiveness of a complex intervention in reducing deficient cognitive development in two-year-old children in rural Vietnam.
- To address multiple modifiable risks impacting early childhood development.
- To provide evidence for scalable interventions in resource-constrained settings.
Main Methods:
- A two-arm parallel-group cluster-randomised controlled trial was conducted in 84 communes in Ha Nam Province, Vietnam.
- The intervention, 'Learning Clubs', included perinatal information, learning activities, and social support delivered through community groups and home visits.
- 1008 pregnant women were enrolled, with 42 communes in the intervention arm and 42 in the control arm receiving usual care.
Main Results:
- The study is pre-results; no findings are available yet.
- The primary outcome is the Bayley Scales of Infant and Toddler Development Cognitive Score at two years of age.
- The trial is powered to detect a significant difference in cognitive scores between intervention and control groups.
Conclusions:
- The study aims to provide critical insights into effective strategies for promoting early childhood development in low-resource settings.
- Findings will inform public health policies and interventions for vulnerable populations.
- Successful outcomes could lead to wider implementation of the 'Learning Clubs' program.
Introduction:
Optimal early childhood development is an international priority. Risks during pregnancy and early childhood have lasting effects because growth is rapid. We will test whether a complex intervention addressing multiple modifiable risks: maternal nutrition, mental health, parenting capabilities, infant health and development and gender-based violence, is effective in reducing deficient cognitive development among children aged two in rural Vietnam.
Methods And Analysis:
The Learning Clubs intervention is a structured programme combining perinatal stage-specific information, learning activities and social support. It comprises 20 modules, in 19 accessible, facilitated groups for women at a community centre and one home visit. Evidence-informed content is from interventions to address each risk tested in randomised controlled trials in other resource-constrained settings. Content has been translated and culturally adapted for Vietnam and acceptability and feasibility established in pilot testing.We will conduct a two-arm parallel-group cluster-randomised controlled trial, with the commune as clustering unit. An independent statistician will select 84/112 communes in Ha Nam Province and randomly assign 42 to the control arm providing usual care and 42 to the intervention arm. In total, 1008 pregnant women (12 per commune) from 84 clusters are needed to detect a difference in the primary outcome (Bayley Scales of Infant and Toddler Development Cognitive Score <1 SD below standardised norm for 2 years of age) of 15% in the control and 8% in the intervention arms, with 80% power, significance 0.05 and intracluster correlation coefficient 0.03.
Ethics And Dissemination:
Monash University Human Research Ethics Committee (Certificate Number 20160683), Melbourne, Victoria, Australia and the Institutional Review Board of the Hanoi School of Public Health (Certificate Number 017-377IDD- YTCC), Hanoi, Vietnam have approved the trial. Results will be disseminated through a comprehensive multistranded dissemination strategy including peer-reviewed publications, national and international conference presentations, seminars and technical and lay language reports.
