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.

Further study details as provided by East Carolina University:

Primary Outcome Measures:
  • physical activity [ Time Frame: 4 months ]
    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

Secondary Outcome Measures:
  • BMI [ Time Frame: 4 months ]
    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

Enrollment: 60
Study Start Date: July 2010
Study Completion Date: April 2013
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Physical Activity
Participants will receive 7 weeks of weekly news letters and phone calls. The news letters and phone calls will include information about physical activity and ways to increase physical activity levels. This is in addition the standard medical care.
Behavioral: physical activity
physical activity counseling sessions will occur by telephone weekly for 2 months
No Intervention: Standard Medical Care
Participants will receive standard medical care

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.
