(HEALTH.USNEWS) — Researchers are debating the merits of recent guidelines that recommend all children aged 9 through 11 be screened for high cholesterol levels, along with certain groups of younger children and teenagers.

The guidelines were written by a panel convened by the U.S. National Heart, Lung, and Blood Institute, endorsed by the American Academy of Pediatrics and published in the journal Pediatrics last November.

But now doctors publishing in the current issue of Pediatrics say the guidelines are too aggressive and not based solidly on evidence. The paper is joined by a rebuttal from the authors of the guidelines.
