Integrating wearable technology into population health monitoring systems for physical activity measurement: meeting report, Utrecht, Kingdom of the Netherlands, 25-27 November 2025

Overview

Physical inactivity remains a major global public health concern, with important implications for noncommunicable disease prevention and health system planning, highlighting the need for more accurate and comparable population-level data. This meeting report summarizes the discussions and outcomes of an expert consultation convened by WHO as part of an ongoing series of technical meetings to support the development of guidance on integrating wearable technologies into national population health monitoring systems for measuring physical activity and sedentary behaviour.

The report presents country experiences from diverse national surveillance systems, outlining approaches to the use of wearable devices alongside self-report instruments and highlighting operational, methodological and logistical challenges. It reviews key technical considerations, including device selection, wear location, wear-time protocols and data-processing algorithms, and examines emerging evidence on the measurement of specific behaviours such as cycling. The document also addresses issues related to participation, representativeness, cost, data management and standardization, and explores opportunities to integrate wearable technologies into WHO’s STEPwise approach to surveillance and broader monitoring frameworks aligned with global physical activity targets. Recommendations focus on advancing global guidance, strengthening research and development, supporting pilot studies and building national capacity. Intended for policymakers, researchers and public health practitioners, it supports WHO’s standard-setting role and informs harmonized approaches to improve the quality, comparability and use of physical activity surveillance data.
