Childhood health is a multidisciplinary research field that focuses on the physical, mental, and social well-being of children from birth through adolescence. Researchers in this field examine a wide range of issues that affect children's health, such as nutrition, physical activity, mental health, chronic diseases, developmental disabilities, and access to healthcare services. The goal of childhood health research is to identify risk factors and interventions that can improve the overall health and well-being of children, ultimately leading to healthier lives and better outcomes in adulthood.
