Help researchers at Duke University Medical Center understand diet, weight, and exercise in families.

If you are the parent of a healthy child between the ages of 4 and 18, both you and your child may be eligible to participate in this research study.

If you are eligible and decide to join the study, you and your child will be asked to:

• Complete a measurement of your heights and weights
• Complete some questionnaires
• Complete a telephone interview about your diets
• Wear an activity monitor for one week
• Complete a DXA scan to measure lean tissue within the body (child only)

Your family will receive up to $60 ($20 per visit for three visits).
