o found that teenage girls needed more support in increasing their physical activity. "If there was more support, there was higher activity," Frenn said. Children with stronger family support were more apt to reach dietary goals than children who relied on their peers or were in an early stage of change, i.e., merely contemplating future changes.

When the researchers looked at students' ZIP codes, they found that Hispanic students in communities with strong cultural ties were more likely to succeed in lowering dietary fat and had stronger family support than those living in more culturally diverse areas. "Although this area was low-income, there was a cultural center, outdoor markets, stores and clinics," Frenn said. "It was a more cohesive neighborhood. There was a protective effect for those kids, when compared to the culturally diverse ZIP code just next door." Researchers say a larger study that follows the students over time is still needed. They're also studying the idea of using a CD for schools without classroom internet access.
