Adherence

Population-wide physical activity interventions, specifically pedometer programs and mass media campaigns, are dominant (cost-saving) and highly cost-effective strategies for improving public health outcomes.

To maximize health benefits and save money, prioritize low-friction, high-reach interventions. Use a pedometer to track steps (aiming for 10,000) and engage with community mass media campaigns. Avoid expensive, high-friction options like frequent travel to exercise physiologists, which offer poor value for the health outcome achieved.

ModerateSupportsHIGH confidence
Based on current evidence of intervention effectiveness, the intervention programs that encourage use of pedometers (Dominant) and mass media-based community campaigns (Dominant) are the most cost-effective strategies to implement and are very likely to be cost-saving.
