We congratulate the authors on this well-deserved recognition and thank them for advancing the conversation on inclusive and methodologically rigorous physical activity surveillance.

There are differences in participation, willingness, and ownership varying by age, education, health, migration background, and PA level. Some groups at higher risk for adverse health outcomes were less likely to participate in monitor measurements, raising concerns for biased population estimates.

As device-based methods become a focal point of physical activity & sedentary behavior surveillance, this paper addresses: Who is represented in wearable-device data?

Authors examined factors associated with:
-Willingness to wear a thigh-worn accelerometer (activPAL)
-Ownership of activity trackers

🏆 Distinguished Paper of the Year Award – 2025 🏆

We are pleased to announce that the paper “Representativeness in Physical Activity Surveillance: Who Wants to Wear an Accelerometer and Who Owns a Personal Activity Tracker?” has been selected as our Distinguished Paper of the Year for 2025.

🚶‍➡️Do researchers really need multiple video reviews to accurately count treadmill steps?
💡New research shows that a single real-time observer delivers <1% deviation—even at varying speeds. ✅
➡️ Fewer resources. Same precision. Smarter data collection.
