At the end of the intervention, families also filled out a survey indicating their confidence level about drinking more water and fewer sugar-sweetened beverages. Ninety percent said they were confident they could help their family drink more water, and 82 percent said they would limit sugar-sweetened beverages.

Body Mass Index -which is a measure of weight in relation to height -- did increase for all of the children in the study, but the increase was significantly less in the tribes that received the community intervention and in-home visits. BMI scores increased by 30 percent in the tribe that received community intervention alone and by 8 percent in the tribes that received both interventions.

The study did not have a control-a tribe that received no intervention-so it is not possible to assess the effect of the community intervention alone or determine whether or not other factors influenced the results. However, authors say the results show that community-based interventions are feasible and acceptable to several different American Indian tribes and they suggest that simple interventions may slow down trends in escalating overweight and obesity in children. The study was conducted from 2001-2006. A larger study involving different Northwest tribes is underway.

In a report released earlier this month, the White House Task Force on Childhood Obesity acknowledged the promise of these types of interventions and the importance of focusing on early childhood.
