The American Academy of Pediatrics (AAP) is recommending that pediatricians start assessing children for their poverty status. The screening begins with a single question — asking parents whether they have difficulty making ends meet at the end of the month.

One in five U.S. children live in poverty, and the academy says that there is growing evidence that the stress of not having safe and secure housing, regular meals and a stable home environment can lead to significant health problems.

"We know children living in poverty have more chronic disease, more severe chronic disease, and have poor early brain development which can impact them when they get to school, and lead to poor academic performance," says Dr. Benard Dreyer, president of the AAP. "Pediatricians deal on a daily basis with the intersection between poverty and health and the well being of children. They understand that they actually aren't separate."
