Researchers at the University of Minnesota School of Public Health are currently involved in the Minnesota NET-Works (Now Everybody Together for Amazing and Healthful Kids) study, an obesity prevention initiative designed to create sustainable change in dietary patterns and physical activity levels among children, particularly those from low income, racially diverse populations most vulnerable to childhood obesity. More than 500 preschool-age children (2-4 years) are taking part in the study along with their parents or primary-caregivers.
