Researchers examined data on more than 8,000 fifth-, seventh- and ninth-grade students who underwent school-based BMI screening in California from 2001 to 2008. High BMI cut points used were the 85th, 95th 97th and 99th percentiles or higher.
When the researchers examined the prevalence of high BMI among girls, they found:
* Black and American Indian girls had increases in three of the four BMI cut points.
* Hispanic girls experienced an increase followed by a plateau after 2005.
* White girls’ prevalence increased from 2001 to 2005 before declining to 2001 rates.
* Asian girls experienced no change.
