Translating Indoor Air Quality Data Into Action
Translating Indoor Air Quality Data Into Action: A Randomized Trial Of Tiered Information Strategies To Improve Household Air Quality
Poor indoor air quality affects the health of millions of Americans. People spend most of their time indoors, yet indoor air can be more polluted than outdoor air. Many everyday activities, such as cooking, using fireplaces, cleaning, and using air fresheners, affect indoor air quality, but most people don't know how their choices affect the air they breathe.
This study will test whether giving people information about their indoor air quality motivates them to make healthier choices. We will work with 120 households, providing them with air quality monitors and sending different types of information about their indoor air quality. Through randomized assignment, some will receive general tips, while others will get personalized messages based on their home's air quality patterns.
By understanding how to best help people create healthier indoor environments, respiratory health can e protected across diverse communities. This research could lead to practical, affordable ways for families to breathe cleaner air at home.

描述
Inclusion Criteria:
- Is an active female participant in PRESTO (aged 21-45 years and trying to conceive at PRESTO enrollment, per PRESTO eligibility) who has completed the PRESTO baseline questionnaire and has not withdrawn from PRESTO.
- Lives in the United States and has a residence where a monitor can be safely placed for approximately four months after the baseline period.
- Has home Wi-Fi internet that the monitor can connect to.
- Has a smartphone or tablet that can run the monitor's companion app.
- Does not plan to move out of her current home within the next 6 months.
- Is willing to complete the study activities: monthly online questionnaires for 6 months, four 2-day activity logs, keeping the monitor plugged in at home for about 4 months, undergo random assignment, receiving study emails, text messages, and other communication, and returning the monitor at the end.
- Be able to provide informed consent in English.
Exclusion Criteria:
- Currently has an indoor air quality monitor in the home that displays levels of particles, VOCs, or CO2 (smoke alarms, carbon monoxide alarms, and radon detectors do not count). Rationale: households that already see IAQ data cannot provide a true "no-monitor" baseline period.
- Is an employee, student, or trainee of any member of the study team.

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
有源比较器：LCM-O (monitor only)
Participants randomized to this arm will only receive a LCM-O monitor. |
Indoor air quality monitor with real-time display and companion app; standard setup and safety guide; routine study operational messages (e.g., questionnaire reminders), which contain no IAQ content. |
|
有源比较器：LCM-R (monitor + generic reminders)
Participants randomized to this arm will receive a LCM-O monitor and generic reminders. |
Everything in Arm 1, plus a brief generic IAQ tip and reminder to review the monitor every two weeks, drawn from a fixed library based on EPA guidance and the literature (8 messages over 4 months, starting 2 weeks after activation). |
|
实验性的：LCM-I (monitor + personalized insights)
Participants randomized to this arm will receive a LCM-O monitor and personalized insights. |
Everything in Arm 1, plus a personalized message every two weeks that describes patterns in the household's own monitor data from the previous 14 days and suggests one or two specific actions, with links to further information (8 messages, starting 2 weeks after activation). |

Indoor Air Quality (IAQ) Behavior Score
大体时间：Baseline, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months
|
The IAQ Behavior Score measures how human actions, habits, or responses contribute to or mitigate indoor pollution. Data will be collected from a IAQ questionnaire. The score will range from 1-100 and higher scores are more favorable. |
Baseline, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months
