Health at All Ages

Children’s Health

NIH research addresses the health and well-being of children throughout their lives, from fetal development through adolescence. This research helps children, adults, families, and communities improve health so that our children can fulfill their dreams.


The face of aging is changing dramatically across the nation. Life expectancy nearly doubled over the past century, and we saw a 10-fold increase in the number of Americans age 65 or older. Americans are not only living longer, they’re also achieving higher levels of education, living in poverty less often, and experiencing increasingly lower rates of disability. NIH research is exploring new approaches to help make these later years as healthy and productive as possible.
