School-Based Intervention to Increase Physical Activity Among Adolescent Females

August 5, 2016 updated by: National Heart, Lung, and Blood Institute (NHLBI)

Interventions to Increase Adolescent Physical Activity

Physical inactivity is a major public health problem in the United States. Research has shown that physical activity levels decline during adolescence, and the decline is greater in females than males. The purpose of this study is to evaluate a life-skills oriented physical activity intervention at increasing activity levels and decreasing cardiovascular risk factors in adolescent females.

Detailed Description

Physical activity levels decline dramatically during adolescence, particularly among females, with the decline most apparent among African Americans. The health benefits of regular physical activity are well-known; individuals who are active have lower rates of obesity and less incidence of cardiovascular disease. Because physical activity behaviors often develop during childhood, it is important to develop programs specifically for adolescents to encourage them to adopt and maintain a physically active lifestyle. Unfortunately, few programs have been developed that specifically focus on adolescents, and the long-term effectiveness of these programs is unknown. This study will evaluate the effectiveness of a life-skills oriented Comprehensive Physical Activity Program (CAP) at increasing activity levels in adolescents. Participants in the CAP program will develop new behavioral skills, which will assist them to continue a physically active lifestyle once the program ends. The purpose of this study is to compare CAP versus a standard physical education (PE) class at increasing physical activity levels and decreasing cardiovascular risk factors in adolescent African American and Caucasian females.

This study will enroll 9th grade female students who attend a high school in Baltimore, Maryland. They will be randomly assigned to participate in either a standard PE class or CAP. Participants in the CAP program will also receive support from a family member to ensure that they receive encouragement for engaging in exercise. Baseline assessments will include physical activity level; cardiorespiratory fitness; cardiovascular risk factors, including blood pressure, lipoproteins, and body mass index (BMI); and psychosocial factors. Participants will attend follow-up visits at the end of each school year in the 9th, 10th, and 11th grades.
