Infant health is a research area that focuses on the health and well-being of newborns and young children up to the age of one year. This field of study encompasses a wide range of topics, including prenatal care, vaccinations, nutrition, developmental milestones, and common illnesses that affect infants. Researchers in this area often work to identify risk factors for infant health problems, develop interventions to improve outcomes, and study the long-term effects of early health conditions on overall well-being. This research is critical for shaping public health policies and practices to ensure that infants have the best possible start in life.
