Doctors Welcome WHO Focus On Wearables
The World Health Organisation (WHO) is increasing its attention on wearable technology – smartwatches and activity trackers – as a potential tool for improving public health. Discussions at a recent WHO meeting in Montreal highlighted the promise of these devices in accurately measuring physical activity levels and combating increasingly sedentary lifestyles.
A More Accurate Picture of Activity
Traditionally, assessing physical activity has relied on individuals self-reporting their activity levels. However, physicians at the Montreal meeting noted that these self-reported surveys often underestimate the extent of inactivity. Wearable devices offer a potential solution by providing continuous, objective, and real-time data.
Bridging the Gap Between Advice and Action
Dr. B. Venkat Nani Kumar, a consultant in internal medicine, explained that wearable technology can “bridge the gap between lifestyle advice and measurable behaviour.” He emphasized the direct correlation between metrics tracked by these devices – such as step count, moderate-to-vigorous physical activity, and sedentary time – and health outcomes like cardiovascular disease, diabetes, and mental health.
Implications for Global Health
The potential benefits of widespread wearable technology use are particularly significant for countries like India and other low and middle-income nations facing a growing burden of lifestyle-related diseases. Affordable smartwatches, standardized under WHO guidance, could bolster national health surveillance systems and facilitate community-level health screenings.
The Need for Inclusive Design and Data Security
Doctors also stressed the importance of ensuring that wearable devices are validated across diverse populations. Specifically, they noted the need for devices to accurately recognize varied movement patterns and step-equivalents, particularly among aging individuals. Alongside this, data privacy and the ethical use of health information are paramount concerns.
What’s Next?
The WHO’s roadmap includes the development of open-source algorithms and independent evaluation processes. However, doctors cautioned that robust regulatory frameworks will be essential to ensure the responsible implementation of this technology. Standardized guidelines for wearable device accuracy and data security could emerge in the coming years. Analysts expect further advances in artificial intelligence and digital health tools to contribute to more sophisticated monitoring of physical activity. A possible next step could be pilot programs in select countries to assess the feasibility and impact of integrating wearable data into existing health systems.
