Parks Associates’ new research shows that connected health device ownership — including digital fitness trackers, networked weight scales, connected treadmills and blood pressure meters — has risen from 24 to 33 percent of U.S. broadband households between 2013 and 2015.

Adoption of wearables and connected health devices is growing, as evidenced by the stellar growth of Fitbit in 2015, according to Harry Wang, Director, Health and Mobile Product Research, Parks Associates. The health and wellness industry is also speeding up its pace of innovation.

“These consumers face a variety of health and mobility challenges, so there is tremendous potential for accelerated adoption, improved outcomes, and ultimately significant cost savings for both companies and consumers,” Wang said. “Interoperability and standards compliance will be the primary challenges as companies look to expand the connected health market and engage this demographic.”

The research firm reports 37 percent of consumers aged 18-24 own a connected health device, while 42 percent of consumers aged 24-34 own one. Among consumers 65 and older, 31 percent own a connected health device.

Parks has found that digital pedometers and fitness trackers experienced the most growth, with their use among U.S. broadband households doubling from 5 to 10 percent between 2013 and 2015. Connected exercise equipment remains the most popular health device at nearly 14%.

Another Parks’ insight found that 13 percent of U.S. broadband households own two or more connected health devices.
