 Independent Tailored Intervention Group If you are assigned to this group, you will be asked to exercise and to improve your diet to the best of your ability. In order to do this, you will 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 that will also provide you 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.
