The purpose of the study is to learn how to make homes more supportive of healthy eating and
physical activity. As part of the study, participants will be randomly assigned to one of two
groups. One group will receive materials with information on healthy eating and physical
activity. The materials will be mailed 3 times over a 5 month period. The other group will
work with a coach to make their homes more supportive of healthy eating and physical
activity. Working with a coach involves 3 home visits and 4 coaching telephone calls over a 5
month period. This group will also receive materials by mail 4 different times. All
participants will be asked to complete 7 telephone interviews over a 1 year period.
Participants will also be asked to wear an accelerometer, a small portable device that tracks
movement from physical activity, for 7 days at 2 different points in the study.
