Few countries utilize device-based physical activity (PA) measurements in national surveillance systems. This review highlights diverse methodologies, emphasizing the need for standardization to improve global public health monitoring and data comparability.
Area of Science:
- Public Health Surveillance
- Epidemiology
- Measurement Science
Background:
- Physical activity surveillance is crucial for public health.
- Current systems predominantly use self-report, limiting accuracy.
- Device-based measurements offer improved population estimates but are underutilized.
Conclusions:
- Device-based physical activity measurement is infrequently used in national surveillance systems.
- Methodological diversity hinders cross-country comparability, necessitating standardized approaches.
- Findings can guide the integration of device-based measurements into future surveillance systems.
