Funded by the Cowles Foundation from 1996-2000, the Amherst Health and Activity Study (AHA) assessed physical activity and health habits of children and teenagers and family and friend support for these habits. Adults and children were surveyed regarding physical activity type and frequency, environmental factors, household influences, physical activity of adults in the household, the household demographics, the child’s friends, the social support and exercise, and social support and exercise. This was one of the first studies to use accelerometers in a large study.
