Brief Summary
This approach will train peer mentors to deliver a culturally appropriate intervention and provide social support that is critical for facilitating and sustaining health behavior change. The objective is to compare the efficacy of an innovative healthy lifestyle skills mentoring program (Mentored Planning to be Active \[MBA\]) to a teacher led program (PBA) for increasing physical activity in Appalachian high school teens. MBA emphasizes the social determinants of health by using a social networking approach that trains peer mentors to support targeted teens

Outcome Measures
Primary Outcomes (3)
Change in Body Mass Index From T1 to T3
Body mass index is caculated as weight in kilograms divided by the square of height in meters. The measure is the change in BMI from baseline to 9 months post-baseline.
T1 (Baseline) to T3 (9 months-post baseline)
Change in Total Body Weight From T1 to T3
Change in total body weight from baseline to 9 months post-baseline.
T1 (baseline) to T3 (9-month post baseline)
Change in Pounds of Body Fat From T1 to T3
Body fat in pounds measured by Tanita Body Composition Analyzer. This equipment provides estimated values for each measured value of body fat percentage, fat mass, fat free mass, muscle mass and bone mass by the DXA method, estimated value for the total body water measured value by the dilution method and estimated value for the visceral fat rating by MRI method using the Bioelectrical Impedance Analysis (BIA method). The Tanita Body Composition Analyzer measures body composition using a constant current source with a high frequency current (6.25kHz, 50kHz, 90μA). The 4 electrodes are positioned so that electric current is supplied from the electrodes on the tips of the toes of both feet, and voltage is measured on the heel of both feet. Body weight measured with shoes and socks removed. Calculated to the nearest 0.2 pounds.

Study Arms (4)
Mentoring to be Active
EXPERIMENTALTrained teen mentors will deliver the physical activity curriculum to high school students in a school setting. Physical activity will be measured with accelerometers.
Planning to be Active
ACTIVE COMPARATORHigh school teachers will deliver the physical activity curriculum (usual care) to high school students enrolled in health education courses. Physical activity will be measured with accelerometers.
Peer Mentors
NO INTERVENTION11 and 12 grade-level trained mentors who lead the Mentoring to be Active (MBA) experimental group as peer mentors.
High School Teachers
NO INTERVENTIONHigh School teachers who taught the usual care healh classes for the Planning to be Active (PBA) active comparator group.
Interventions
Trained high school mentors will deliver a 10 session curriculum targeting physical activity to younger teens.
Health education teachers will deliver the 10 session curriculum targeting physical activity to high school students enrolled in health courses.
Eligibility Criteria
You may qualify if:
- th or 10th grade students as participants
- th or 12th grade students as mentors
- Classroom teachers who instruct health education or physical education to 9th and 10th grade students.
- Not expected to move from school prior to conclusion of study
- Speaks English
You may not qualify if:
