While children spend a substantial amount of time in school, more than half of kids aged 5 to 14 years are also spending time in a child-care setting. This is also an important out-of-home setting for preschool-aged children. This research brief outlines federal food programs and regulations that govern nutrition and physical activity in child-care settings—and what research has demonstrated about the nutritional quality of foods offered in child-care settings.
