Campaigns and Informational Approaches to Increase Physical Activity: Classroom-Based Health Education Focused on Providing Information
These programs consist of health education classes in elementary, middle, or high schools that aim to help students develop skills needed to adopt healthier behaviors. Class content:
- Is usually nonspecific (i.e., teachers educate students about physical inactivity, nutrition, smoking, and alcohol and drug misuse)
- May include behavioral skills components (e.g., role-playing, goal-setting, contingency planning)
- Usually does not include spending additional time participating in physical activity
Summary of Task Force Recommendations and Findings
The Community Preventive Services Task Force finds insufficient evidence to determine the effectiveness of classroom-based health education focused on providing information in increasing physical activity levels and physical fitness because of inconsistent findings.
Results from the Systematic Review
Ten studies qualified for the review.
- The studies reviewed showed variable effects of these interventions on time spent in physical activity outside the school setting.
- Three study arms from two studies showed increases in activity.
- Five study arms from two studies showed decreases in self-reported activity.
- Five study arms from one study found positive changes in self-reported behavior.
- Eleven study arms from two studies found no change or negative changes in self-reported behavior.
- Aerobic capacity was not measured in any of these studies.
- Although findings did not show changes in activity, four of five study arms from three studies showed increases in:
- General health knowledge
- Exercise-related knowledge
- Self-efficacy about exercise
- Effects on body fat measures were mixed, showing decreases in BMI (body mass index) among both boys and girls, but decreases in skinfold measurement among boys only.
These results were based on a systematic review of all available studies, conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice, and policy related to increasing physical activity.
An economic review of this intervention was not conducted because the Task Force did not have enough information to determine if the intervention works.

The findings and conclusions on this page are those of the Community Preventive Services Task Force and do not necessarily represent those of CDC. Task Force evidence-based recommendations are not mandates for compliance or spending. Instead, they provide information and options for decision makers and stakeholders to consider when determining which programs, services, and policies best meet the needs, preferences, available resources, and constraints of their constituents.
