Child Development: The Next Global Health Frontier

Abstract

Recent improvements in child health have led to substantial decreases in child mortality globally.1 While progress is still needed, especially in regions afflicted by conflict and political instability,2 the next step is to promote young children’s development and early learning so they can remain healthy, take advantage of growing educational opportunities, and contribute to their communities’ economic growth. Every year, approximately 249 million children, mainly from low- and middle- income countries, fail to reach their developmental potential in the context of poverty and related health, nutrition, and social factors.3 Recessions and climate change additionally contribute to loss of developmental potential globally.4–7 While principles of early childhood development are universal, a global perspective must consider exposure to extreme poverty and high prevalence of infectious diseases, cultural context, and availability and type of resources. This chapter will describe biological and social factors that influence brain development and early learning and resilience, their cultural context, and examples of successful child development interventions globally. We also provide recommendations to rapidly accelerate the promotion of early childhood development globally with key strategies, including an emphasis on universal prevention programs rather than universal screening, multigenerational models that emphasize universal support for parents and targeted support for high-risk populations, integration of child development programs into child health and nutrition efforts, and use of technology.
