Apple and University of Michigan share early results from various Apple Watch health studies
The Apple Watch continues to play a crucial role in medical research studies around the world. This week, the University of Michigan Health released the first results of what it calls a “landmark three-year observational study” that it first began in 2018 in collaboration with Apple.
As detailed in a new blog post from the University of Michigan Health, the goal of the study is to “recruit a diverse set of participants of ages, races, ethnicities and underlying health issues.” And provide an overview of the baseline. the state of health of a representative group of thousands of people.
Jessica Golbus, MD, is a co-investigator of the study and boasts that one of the study’s “greatest successes” has been its ability to “recruit groups that have been grossly under-represented or unrepresented in the study. digital health research “. According to the data, 18% of the over 6,700 participants were 65 or older, 17% were black and 17% were Asian.
The aim of the study was to “describe and compare key wearable signals (i.e. heart rate, step count, and home blood pressure readings) as a function of age, gender, race, ethnicity and clinical phenotypes.
More details on the study:
Participants wore their Apple Watch for almost 90 percent of study days for an average of 15.5 hours per day. In total, more than 200 million heart rate readings were collected with Apple Watch and 1.1 million blood pressure readings with the Omron blood pressure cuff.
Participants 65 years of age and older had significantly lower resting and walking heart rates, and women had resting heart rates averaging 3 beats per minute higher than men. When stratified by self-reported race, black participants had the highest heart rates and white participants the lowest. Activity levels also varied by race and ethnicity and by the presence of certain clinical conditions. Together, these differences demonstrate that patient-specific context is an important consideration when clinicians interpret portable and home blood pressure data.
The full study results have not yet been released, but preliminary information can be found in the The Lancet Digital Health newspaper.
