Supporting Reading Aloud Beginning Prenatally and in Early Infancy: A Randomized Trial in Brazil

Randomised controlled trials in child and adolescent health in 2023

In the year July 2022 to June 2023 there were 501 publications from randomised controlled trials (RCTs) in child and adolescent health in developing countries identified through a standardised search strategy that has been going for 20 years. This year, trials addressed the widest range of diseases and conditions that affect the health, development and well-being of children, newborns, adolescents and mothers. RCTs reflected old, neglected and new problems, the changing epidemiology of child health, social and economic circumstances in many countries, local and global priorities of low-income and middle-income countries, environmental causes of poor child health, and inequities. The RCTs tested new and refined treatments, diagnostics, vaccines, holistic management, and prevention approaches, and explored many outcomes, including mortality, nutrition, psychosocial measures, and neurodevelopment. The studies were conducted in numerous hospitals and healthcare clinics, schools, and communities, including among some of the world's most disadvantaged populations in humanitarian and refugee emergencies. Some studies are of the highest quality, and others fall short. Many RCTs will influence guidelines, practice and policies for years to come.

Validation of the StimQ2: A parent-report measure of cognitive stimulation in the home

Considerable evidence demonstrates the importance of the cognitive home environment in supporting children's language, cognition, and school readiness more broadly. This is particularly important for children from low-income backgrounds, as cognitive stimulation is a key area of resilience that mediates the impact of poverty on child development. Researchers and clinicians have therefore highlighted the need to quantify cognitive stimulation; however existing methodological approaches frequently utilize home visits and/or labor-intensive observations and coding. Here, we examined the reliability and validity of the StimQ2, a parent-report measure of the cognitive home environment that can be delivered efficiently and at low cost. StimQ2 improves upon earlier versions of the instrument by removing outdated items, assessing additional domains of cognitive stimulation and providing new scoring systems. Findings suggest that the StimQ2 is a reliable and valid measure of the cognitive home environment for children from infancy through the preschool period.

Pre-pandemic support for shared reading buffers adverse parenting impacts: an RCT in Brazil

BACKGROUND

To examine whether (1) a parent-child reading program (Universidade do Bebê [UBB]), conducted in Brazil pre-pandemic can support parenting and parent-child reading 6 months into the pandemic, (2) cognitive stimulation at pandemic onset mediates effects of UBB on these outcomes, and (3) UBB pre-pandemic buffers associations between COVID-19-related distress and parenting/parent-child reading 6 months into the pandemic.

METHODS

400 women, either pregnant or with children 0-24 months, were randomized to UBB (n = 200) or control groups. UBB consisted of monthly parent workshops focusing on parent-child reading and a book-lending library. Assessments pre-pandemic (June-2019) and at pandemic onset (April-2020) included cognitive stimulation. Assessments 6 months into the pandemic (October-2020) included COVID-19 exposure/impact/distress, as well as parenting and parent-child reading.

RESULTS

133 families (n = 69 UBB) contributed data 6 months into the pandemic. Participation in UBB pre-pandemic was associated with parent-child reading but not parenting 6 months into the pandemic. Indirect effects of UBB through cognitive stimulation at pandemic onset were observed for both outcomes. Increased COVID-19-related distress was significantly associated with reduced parenting/parent-child reading 6 months into the pandemic in the control group only.

CONCLUSION

Promotion of cognitive stimulation pre-pandemic may have reduced risk for effects of the pandemic on parenting/parent-child reading.

CLINICAL TRIAL REGISTRATION

The trial has been registered with the Brazilian Clinical Trials Registry RBR-29RZDH on 05/28/2018.

IMPACT

This is the first study showing sustained impacts of a reading aloud intervention beginning in pregnancy and early infancy implemented pre-pandemic. Findings suggest that participation in a reading-aloud intervention buffered associations between COVID-19 distress and parenting/parent-child reading 6 months into the pandemic. Novel empirical evidence suggests that promotion of cognitive stimulation prior to the pandemic may buffer its impacts on parenting and parent-child book reading following onset in low- and middle-income countries. Findings provide important new support for implementation of parent-child reading aloud programs and likely have implications for early childhood development beyond the COVID-19 pandemic for disasters generally.
