Study says Kid's Asthma Out of Control

Four out of five kids with asthma don't keep their symptoms under control, a new study shows.

University of Rochester researcher Jill S. Halterman, M.D., MPH, and colleagues analyzed data from a telephone survey of 975 asthmatic children in Alabama, California, Illinois, and Texas.

Among children with persistent asthma, they found:

• More than one in three kids — 37 percent — isn't getting the prescription drugs needed for asthma control.
• An additional 43 percent of these kids have asthma drugs but still aren't controlling their asthma.
• Only 20 percent of kids with persistent asthma keep their symptoms under control.
