Nonvalidated home blood pressure devices dominate the online marketplace in Australia: major implications for cardiovascular risk management
Self-home blood pressure (BP) monitoring is recommended to guide clinical decisions on hypertension and is used worldwide for cardiovascular risk management. People usually make their own decisions when purchasing BP devices, which can be made online. If patients purchase nonvalidated devices (those not proven accurate according to internationally accepted standards), hypertension management may be based on inaccurate readings resulting in under- or over-diagnosis or treatment. This study aimed to evaluate the number, type, percentage validated, and cost of home BP devices available online. A search of online businesses selling devices for home BP monitoring was conducted. Multinational companies make worldwide deliveries, so searches were restricted to BP devices available for one nation (Australia) as an example of device availability through the global online marketplace. Validation status of BP devices was determined according to established protocols. Fifty nine online businesses, selling 972 unique BP devices were identified. These included 278 upper-arm cuff devices (18.3% validated), 162 wrist-cuff devices (8.0% validated), and 532 wrist-band wearables (0% validated). Most BP devices (92.4%) were stocked by international e-commerce businesses (eg, eBay, Amazon), but only 5.5% were validated. Validated cuff BP devices were more expensive than nonvalidated devices: median (interquartile range) of 101.1 (75.0–151.5) versus 67.4 (30.4–112.8) Australian Dollars. Nonvalidated BP devices dominate the online marketplace and are sold at lower cost than validated ones, which is a major barrier to accurate home BP monitoring and cardiovascular risk management. Before purchasing a BP device, people should check it has been validated at https://www.stridebp.org
The 2020 “WHO technical specifications for automated non-invasive blood pressure measuring devices with cuff”
High systolic blood pressure (BP) is the single leading modifiable risk factor for death worldwide. Accurate BP
measurement is the cornerstone for screening, diagnosis, and management of hypertension. Inaccurate BP measurement
is a leading patient safety challenge. A recent World Health Organization report has outlined the technical specifications
for automated noninvasive clinical BP measurement with cuff. The report is applicable to ambulatory, home, and office
devices used for clinical purposes. The report recommends that for routine clinical purposes, (1) automated devices be
used, (2) an upper arm cuff be used, and (3) that only automated devices that have passed accepted international accuracy
standards (eg, the International Organization for Standardization 81060-2; 2018 protocol) be used. Accurate measurement
also depends on standardized patient preparation and measurement technique and a quiet, comfortable setting. The World
Health Organization report provides steps for governments, manufacturers, health care providers, and their organizations
that need to be taken to implement the report recommendations and to ensure accurate BP measurement for clinical
purposes. Although, health and scientific organizations have had similar recommendations for many years, the World Health
Organization as the leading governmental health organization globally provides a potentially synergistic nongovernment
government opportunity to enhance the accuracy of clinical BP assessment.The 2020 “WHO Technical Specifications for Automated Non-Invasive Blood

Lifestyle management of hypertension: International Society of Hypertension position paper endorsed by the World Hypertension League and European Society of Hypertension
Hypertension, defined as persistently elevated systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) at least 90 mmHg (International Society of Hypertension guidelines), affects over 1.5 billion people worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (e.g. coronary heart disease, heart failure and stroke) and death. An international panel of experts convened by the International Society of Hypertension College of Experts compiled lifestyle management recommendations as first-line strategy to prevent and control hypertension in adulthood. We also recommend that lifestyle changes be continued even when blood pressure-lowering medications are prescribed. Specific recommendations based on literature evidence are summarized with advice to start these measures early in life, including maintaining a healthy body weight, increased levels of different types of physical activity, healthy eating and drinking, avoidance and cessation of smoking and alcohol use, management of stress and sleep levels. We also discuss the relevance of specific approaches including consumption of sodium, potassium, sugar, fibre, coffee, tea, intermittent fasting as well as integrated strategies to implement these recommendations using, for example, behaviour change-related technologies and digital tools
Reducing salt intake to prevent hypertension and cardiovascular disease
The Pan American Health Organization–WHO Regional Expert Group on Cardiovascular Disease Prevention through Dietary Salt Reduction produced a policy statement out
lining the recommendations for a population-based approach to reduce dietary salt
intake in the Americas (2010). While government legislation of salt reduction lags in developing countries, public health campaigns play an important role in educating and encouraging people to consume less salt. Stroke mortality rates, the key outcome of increased blood pressure, are very high in Latin America and the Caribbean, with annual rates up to 77.5 deaths per 100,000 women in St. Lucia
