Sharman and his team also found that cost was the most significant barrier that may sway shoppers away from purchasing home blood pressure devices that have been validated. “High blood pressure is the single largest risk factor for cardiovascular disease worldwide, so it’s really important to measure blood pressure accurately,” says James Sharman, PhD, the deputy director of the Menzies Institute for Medical Research at the University of Tasmania, who led the study.ĭr. Just 8 percent of the 162 wrist-cuff devices had been validated and none of the more than 530 wristband-style wearables had been validated at the time of the study. Of the 278 upper-arm cuff devices included in the new study, which was published in April 2020 in the journal Hypertension, less than 20 percent had been validated, meaning the cuffs had not been proved to give accurate readings according to internationally accepted standards. Almost 95 percent of the devices hadn’t been validated for accuracy.Īlthough the team looked only at devices available to Australian consumers, over 90 percent of these products were sold on global e-commerce sites including Amazon and eBay. ![]() Researchers from seven universities and the World Hypertension League analyzed more than 970 home blood pressure devices being sold by nearly 60 online retailers. If you have an at-home blood pressure monitor, the reading may not be as accurate as you think. ![]()
