Bridging the Hypertension Knowledge Gap with Wearable Technology

A recent JAMA survey revealed that many U.S. adults lack key knowledge about hypertension, including the correct threshold for diagnosis and the importance of regular monitoring. Despite widespread awareness of prevention strategies such as diet and exercise, fewer than one-quarter of people with hypertension reported checking their blood pressure more than once a week. This knowledge-behavior gap underscores the need for better tools to support both awareness and action. 

Knowledge Gaps in Hypertension 

The survey found that only 13% of respondents correctly identified 130/80 mm Hg as the cutoff for hypertension. Many still believed the older threshold of 140/90 mm Hg, while others were unsure. Misconceptions extended further: over one-third thought hypertension nearly always presents symptoms, and 40% believed relaxation alone indicates normal blood pressure. 

These gaps matter because hypertension is often asymptomatic until complications arise, making accurate understanding and proactive monitoring critical. 

The Role of Wearables in Hypertension Awareness 

Emerging wearable technologies can help close this gap by making blood pressure monitoring more frequent, passive, and accessible. Devices capable of cuffless blood pressure tracking, pulse oximetry, and continuous cardiovascular monitoring are already in development and undergoing validation under standards such as ISO 81060-2 and ISO 81060-7. 

For individuals, wearables can: 

• Provide real-time blood pressure readings and alerts. 

• Track long-term trends, making it easier to see the effects of lifestyle changes. 

• Offer app-based education modules that reinforce accurate knowledge about hypertension. 

For researchers and developers, these devices present new opportunities for inclusive clinical research studies. Ensuring accuracy across diverse populations—considering variables like skin tone using the Monk scale—is essential for equitable technology deployment. 

Enhancing Adherence and Engagement 

One striking survey finding was that while most respondents said they were willing to take steps to manage hypertension, far fewer consistently did so. Wearables can help bridge intention and action by: 

• Sending reminders for physical activity or medication. 

• Integrating informed consent–based data sharing with clinicians for remote monitoring. 

• Supporting remote trial compliance in clinical studies, making it easier to evaluate device effectiveness outside the lab. 

  
  

Building Trust Through Validation 

For wearable technology to truly impact public health, devices must be validated through regulatory-grade clinical trials. CRO partners like Parameters Research Laboratory ensure that emerging blood pressure wearables undergo rigorous testing aligned with GCP, ISO 14155, and FDA submission requirements, generating data that regulators and clinicians can trust. 

Conclusion 

The JAMA findings highlight a pressing challenge: knowledge alone isn’t enough to change outcomes in hypertension. Wearable technology, when validated and implemented effectively, has the potential to transform awareness into daily action—empowering individuals while providing clinicians and regulators with reliable, continuous data.
