PACEAdol: PACE+: Counseling Adolescents for Exercise and Nutrition
Study Details
Study Description
Brief Summary
PACE+ was developed to address the increased number of adolescents in our country that are at risk for cardiovascular disease, cancer, and other diseases due to inactivity, obesity, and malnourishment. PACE+ will evaluate the efficacy of an integrated clinical and home-based intervention to improve physical activity and nutrition behaviors in adolescents ages 11-15 over a period of 2 years.
This study is unique in that it will be one of the first to evaluate a combined physical activity and nutrition intervention for youth that revolves around the primary health care setting. The PACE+ intervention is particularly innovative in that three components - computer, provider counseling, and an extended home-based intervention - are unified through a common theoretical framework.

Detailed Description
Improved physical activity (PA) and nutrition behaviors in adolescents show great promise to reduce risk of cancers and other diseases. Fewer than 20% of adolescents meet recommendations for fat or fruits & vegetables consumption, and only 50% of adolescent girls and 67% of boys meet recommendations for vigorous PA. PACE+ will evaluate an integrated clinical and home-based intervention to improve physical activity (PA) and nutrition behaviors in adolescents. The intervention has three integrated components: a computer assessment and action planner; provider counseling; and 24 months of extended phone & mail contact. 768 male and female adolescents age 11 through 15; will be recruited from six healthcare settings. Subjects will be randomly assigned within practices to two successive one-year "doses" of PACE+ or a comparison condition involving counseling for sun protection behaviors. PACE+ assesses four behaviors: 1) dietary fat, 2) fruits & vegetable consumption, 3) physical activity, and 4) sedentary behavior. Primary behavioral outcomes, secondary outcomes, and selected mediators and process variables will be measured prior to the first office visit and at 6, 12 and 24 months. Primary outcomes will be measured by the 7-day physical activity recall and 3-day food record of fruits & vegetables and fat at 12 months. Secondary outcomes include adiposity, fitness, BMI, psychosocial mediators of change, and body image. Potential risks are psychological and physical, however the risks are slight and of low likelihood. Benefits include helping bring about healthier lifestyles to prevent weight gain and reduce premature morbidity and mortality due to cancer, cardiovascular disease and other health problems. This study will be the first to evaluate a combined physical activity and nutrition intervention for youth that revolves around the primary health care setting.

| Experimental: PACE+ Intervention Intervention Group |
Behavioral: PACE+
Patients assigned to the intervention group will receive intervention strategies over a the course of 2 years including: (1) completion of a 45-minute office-based computer program resulting in an assessment and action plan for improvement in physical activity and nutrition behaviors; (2) a provider counseling session immediately following the computerized assessment, followed by (3) 12 phone calls and 24 mailings over a 24-month period conducted by PACE+ staff members
Other Names:

| No Intervention: Sun Protection Control / Comparison group. Patients assigned to the comparison group will receive intervention strategies over a the course of 2 years including: (1) completion of a 30-minute office-based computer program resulting in on-screen feedback to address excess sun exposure prevention, and (2) 4 phone calls and 4 mailings over a 24-month period conducted by PACE+ staff members. |
Outcome Measures
Primary Outcome Measures
