Low-income African American girls who participated in weight loss programs over two years showed little improvement, according to two new studies published in the Journal of the American Medical Association. Researchers found little change in the girl’s body mass index (BMI), which is a measure of body fat based on height and weight.

In the first study from Stanford University girls, were offered dance classes and other opportunities to get active. One group was offered hip-hop and other types of dance classes five time a week. Researchers also went to their homes and helped them find activities they could do instead of spending time in front of the TV or computer. The other group just received newsletters with activities focusing on health and nutrition. Researchers also met quarterly with their parents.
