Gestation and the first years of life are the foundation for human development and arguably the development of nations and the future of our planet. Decades of research have documented the enormous harms that poor health, household food insecurity, malnutrition, a lack of early stimulation opportunities, and physical and psychological abuse can inflict in the bodies and minds of children. The consequences of adverse early life experiences can have a lifelong impact, including a higher risk of obesity, noncommunicable diseases, poor social functioning and lower levels of education and income. Consistent evidence has shown how these factors also strongly and negatively affect the agency, self-efficacy, and, ultimately, the physical and mental health of mothers, which is crucial for them as well as the well-being of their families. This also decimates the social fabric needed for societies to develop with equity.
In addition to having already identified many modifiable risk factors for delayed early childhood development and poor maternal health, we now have a constellation of multicomponent evidence-based interventions that cut across the socio-ecological model that can be used to prevent these detrimental, unjust and unnecessary human development outcomes from happening. The main challenge today is that this knowledge is not being translated into policies and programs on a large scale. Why? In our view, this is in part because, until recently, we had not benefited from the field of implementation science.
Implementation science in public health focuses on the development of innovative methods and strategies that advance the use of evidence-based interventions in targeted settings such as communities, schools and hospitals to improve public health. Through implementation science, mixed-method research tools and approaches have been developed that can be used to guide the effective scaling up of and sustainability of multicomponent, well-coordinated maternal-child health programs across the globe. For example, at YSPH, we are conducting research to figure out how to empower countries to improve their cultural environments and policies so that appropriate infant feeding practices are properly integrated and early childhood development outcomes are more positive. We are also doing research on how to advance the scaling up of evidence-based interventions to reduce the unacceptably high maternal mortality rate among low-income women and women of color because of postpartum hypertension and cervical cancer.
