 If you are assigned to this group, you and your mother, as a team, will be asked to exercise and to improve your diets to the best of your ability. In order to do this, you will each receive a personalized notebook of diet and exercise information, which will be mailed to you at the start of the intervention. About every 6-7 weeks throughout the 1-year intervention period, you also will receive 6 personalized newsletters, which will also provide you and your mother with more information. After each mailing, you will be asked to complete a short survey 16-20 questions about the information you received and how useful it was for you. You will be asked to return the survey in a prepaid, addressed envelope that was sent with the materials.
