The number of children hospitalized with a hypertension-related illness nearly doubled between 1997 and 2006.
Doctors who analyzed a nationwide pediatric database think childhood obesity may be at least partly to blame.
Charges for inpatient care for kids with high blood pressure increased by 50-percent, reaching 3.1 billion. The average time spent in the hospital for these children was double that of kids with other illnesses.
Children hospitalized with hypertension were most likely to be boys over age 9, and African American.
