Parent's Guide for the Assessment and Treatment of the Overweight Child

Do you have a child you think may be overweight or obese? The purpose of this Parent's Guide is to explain how overweight is assessed in adults and children. We discuss some of the essential components of successful approaches to weight management in children. Our goal is to provide you with the basic information you will need as a parent or caregiver of an overweight child. The information in this guide will provide a basis for you to identify professional resources in your community that you can reasonably expect to help you and your family work together to help your overweight child.
