Insights
Quality early caregiving and reduced diarrheal illness are key to improving child growth. Interventions should address maternal depression and enhance mother-child interactions to combat childhood undernutrition and stunting.
Area of Science:
- Child Development
- Global Health
- Nutritional Science
Background:
- Undernutrition causes over 50% of childhood deaths globally.
- Stunting and developmental delays affect one in three children worldwide.
- Caregiving processes are critical for child growth and development.
Purpose of the Study:
- Investigate the role of caregiving in children's height-for-age.
- Assess longitudinal effectiveness of nutrition and stimulation interventions.
- Explore mediators of intervention effects on child growth.
Main Methods:
- Longitudinal study of 1302 children from birth to 4 years.
- Path analyses to identify mediators of intervention effects.
- Examined mother-child interaction, maternal depression, and diarrheal illness.
Main Results:
- Mother-child interaction quality mediated intervention effects on height-for-age.
- Diarrheal illness mediated maternal depression effects on child growth.
- Intervention effects on height-for-age were significant via interaction quality.
Conclusions:
- Early caregiving quality is a key mediator for child growth interventions.
- Addressing maternal depression and diarrheal illness is crucial for child growth.
- Integrated programmatic approaches are needed for child nutrition and development.
Background:
Undernutrition contributes to at least half the estimated six million annual childhood deaths worldwide. Furthermore, one in three children fails to meet their developmental potential because of risks including stunting, illness, under-stimulation, poor responsive interactions and maternal depressive symptoms. Our study investigates the role of caregiving processes on children's height-for-age at 2 and 4 years.
Methods:
The Pakistan Early Child Development Scale-up study assessed the longitudinal effectiveness of early nutrition and responsive stimulation interventions on growth and development at 4 years of age. In total, 1302 children were followed up from birth to 4 years. We leveraged path analyses to explore potential mediators of early intervention effects on children's height-for-age at 4 years, including maternal depressive symptoms, mother-child interaction quality, diarrhoeal illness and height-for-age at 2 years.
Results:
Our final model had excellent model fit (comparative fix index = 0.999, Tucker-Lewis index = 0.998, root mean square error of approximation = 0.008) and showed that mother-child interaction quality mediated the effects of both enhanced nutrition and responsive stimulation interventions on height-for-age at 4 years via its longitudinal stability from 2 years of age (β = 0.016, p = 0.005; β = 0.048, p < 0.001, respectively). Further, diarrhoeal illness mediated the effects of maternal depressive symptoms at 1 year post partum on children's height-for-age at 4 years via the longitudinal stability of height-for-age z-score from 2 years of age onwards (β = -0.007, p = 0.019).
Conclusions:
The quality of early caregiving experience mediated the association between both interventions and height-for-age. The effect of maternal depressive symptoms on growth was mediated by diarrhoeal illness. Programmatic approaches to child nutrition and growth must address all these potentially modifiable factors.
