Telephone Physical Activity Intervention in Obese Youth

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine the effectiveness of a telephone-based physical activity (PA) intervention in obese adolescents attending a Health Weight Comprehensive Clinic. Secondary aims focus on increasing the amount of change in obesity markers, namely waist circumference and BMI z-scores. The investigators hypothesize the following: 1.The telephone-based PA intervention will increase PA levels above the mail group; and 2. The telephone-based PA intervention will provide changes in waist circumference and BMI z-scores above the mail group.

Detailed Description
-----------------
Obesity rates in youth have tripled over the past 20 years. Physical activity aids in weight loss and is critical for weight maintenance. Further, physical activity has other physiological and psychological benefits. Obese youth often see specialists for weight loss treatment. Treatment in a pediatric population uses a multi-component approach, but physical activity if often overlooked. Combining physical activity information with physician care and nutritional information could improve weight loss and the overall health of these obese children.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| physical activity | physical activity levels during the 2 month intervnetion will be measured and then physical activity will also be measured during a 2 month follow up period | 4 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| BMI | waist circumference and weight and height will be measured. BMI will be calculated. After the 2 month intervention period the amount of change in waist circumference and BMI will be quantified. These measures will also be examined after a 2 month follow up period | 4 months |
