“MyHeart Counts Cardiovascular Health Study”
The MyHeart Counts Cardiovascular Health Study will utilize mobile health capabilities of smartphones and wearables to assess daily activity measures of the general population and compare these to measures of cardiovascular health risk factors and fitness. How people divide their time among exercise, sedentary behavior, and sleep all affect cardiovascular health, yet to date these have largely gone unmeasured. With the advancement of phone sensors and wearable fitness tracking devices these factors are now more straightforward to gather and measure. The use of smartphones by a large segment of the population allows for data collection on an unprecedented scale. The investigators aim to amass activity and cardiovascular health data on thousands of participants as well as provide significantly more quantitative data on type,duration, and intensity of daily activities. In the second phase of the MyHeart Counts Cardiovascular Health Study (Randomized Assessment of Physical Activity Prompts In A Large Ambulatory Population) the researchers will conduct a randomized controlled clinical trial of four different physical activity prompts (intervention) and their effect on the level of physical activity in the study population as measured by change in step count.
Behavioral - Stand Prompt
The participant will receive a notification asking them to stand or walk if they have been sitting for longer than 60 minutes
Behavioral - Step Prompt
The participant will receive a notification if they are below 5000 steps by 3pm each day asking them to get to 10000 steps.
Behavioral - Cluster Prompt
The participant will receive daily information notifications specific to the activity cluster they fall into based on the activity data collected in phase 1 of the study
