Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Be older than 18 years old

Must not have

Children under the age of 18

Timeline

Screening 3 weeks

Treatment Varies

Follow Up 5 weeks

Summary

This trial will use the 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.

Who is the study for?

This trial is for adults over the age of 18 who are interested in contributing to research on cardiovascular health. It aims to gather data using smartphones and wearables to track daily activities like exercise, sedentary behavior, and sleep.

What is being tested?

The study tests four types of prompts (Stand Prompt, Step Prompt, Cluster Prompt, Read AHA website) designed to increase physical activity. Participants' step counts will be monitored to measure the effectiveness of these prompts.

What are the potential side effects?

Since this study involves non-invasive tracking of activity through mobile devices and does not include medication or medical procedures, no direct side effects are expected from participating.

Change in sleep duration as measured by Apples core motion chip.

Trial Design

5Treatment groups

Active Control

Placebo Group

Group I: Cluster PromptActive Control1 Intervention

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.

Group II: Baseline monitoringActive Control1 Intervention

No feedback is provided to the users. This is the control arm.

Group III: Stand PromptActive Control1 Intervention

Behavioral Intervention Prompt- Participant will receive a notification asking them to stand and walk if they have been sitting for longer than 60 minutes.

Group IV: Step PromptActive Control1 Intervention

The participant will receive a notification if they are below 5000 steps by 3pm each day asking them to get to 10000 steps.

Group V: Read AHA websitePlacebo Group1 Intervention

Daily reminder to read the American Heart Association (AHA) website.
