Cardiogram study: Apple Watch can detect diabetes with an 85% accuracy

Apple Watch - heart sensor

Cardiogram’s latest clinical study has found that the Apple Watch can detect diabetes in those previously diagnosed with the disease with an 85 percent accuracy.

Part of the larger DeepHeart study with Cardiogram and UCSF, it used data from 14,000 Apple Watch users and was able to detect that 462 of them had diabetes by using the Watch’s integrated heart rate sensor. For what it matters, the same type of sensor is also found in many other fitness bands and smartwatches, including those running Google’s Android Wear platform.

Cardiogram’s work builds on the 2015 Framingham Heart Study which showed that resting heart rate and heart rate variability significantly predicted incident diabetes and hypertension. This prompted researchers to use the Watch’s heart rate sensor to see if it could accurately detect a diabetic patient.

Previously, the Cardiogram team used the Apple Watch to detect an abnormal heart rhythm with up to a 97 percent accuracy, sleep apnea with a 90 percent accuracy and hypertension with an 82 percent accuracy when paired with their AI-based algorithm.

Diabetes is a huge problem all around the world. According to CDC, more than 100 million adults in the U.S. are now living with pre-diabetes or diabetes and more than 1 in 4 of them go undiagnosed. So, yes this is big news, since early detection could help in cutting down on diabetes-related diseases before they get out of hand.
