What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study explores whether showing people real-time air pollution levels in their homes changes how they perceive risk and whether they take steps to reduce exposure. About 30 households from the Northern Arapaho tribe will participate, with some receiving monitors that display live pollution data and color-coded risk levels, while others receive devices that only show the time. Surveys before and after the monitoring period will track changes in risk perception and behaviors like avoiding outdoor activities on high-pollution days. The goal is to understand if real-time feedback can encourage healthier choices and inform future environmental health efforts.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Real-time particulate matter (PM) exposure monitors with color-coded risk levels
What this could lead to
If real-time air quality feedback changes how people perceive and avoid pollution risks, it could inform community-based strategies to reduce environmental health hazards.
What could go wrong
The study is small and exploratory, so results may not apply broadly. Also, showing pollution levels might not change long-term behavior.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

30 people

The number who actually took part.

Started

Jul 2022

Finished

Mar 2024

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Participants must live in a household where at least one adult is a member of the N. Arapaho tribe who is a Primary Participant in the related exposure assessment study.
