A study by the Center for Disease Control and Prevention finds that over a 20-year period while obesity rose from 6 percent to 17 percent in children and teens their blood pressure on average remained fairly stable.
Experts say that doesn't mean obesity is harmless to children.
Past research has shown that about 75 percent of obese kids become obese adults as well. Also, obesity carries an increased risk of chronic conditions such as type 2 diabetes, heart disease and arthritis.
