Abstract
Obesity is a particularly important challenge to the health status of Native Americans. This challenge is manifest in the increasing rates of non‐insulin‐dependent diabetes mellitus among Native Americans. Most studies of Native American infants, preschool children, schoolchildren, and adults have confirmed a high prevalence of over weight Historical studies suggest that for many Native American communities the high rates of obesity are a relatively recent phenomenon. The specific reasons for the increase in obesity among Native Americans have not been determined, although it has been hypothesized that Native Americans have a genetic predisposition to over weight in a “westernized” environment of abundant food and decreased energy expenditure. Few detailed studies of diet or of physical activity levels of contemporary Native Americans have been published. Community‐based interventions to modify diet and activity levels to prevent obesity in Native American communities are needed. Preliminary evidence from two formative school‐based programs in the Southwest suggest that Native American communities are receptive to school‐based interventions, and that such programs may be able to slow the rate of excess weight gain and to improve fitness in schoolchildren. Because of the cultural diversity among Native Americans, future studies should focus on collecting community‐ and region‐specific data, and should emphasize the need for obesity prevention through culturally appropriate community‐and school‐based behavioral interventions.
