Observational Study on Flatus Activity and Fiber Intake Using Smart Underwear
This study aims to understand the typical frequency of flatulence (gas) in adults and how it's affected by the fiber you eat. Researchers will use a special "Smart Underwear" device to measure gas activity. You can join if you are 18 or older, live in the US, are not pregnant or breastfeeding, and are willing to wear the device as instructed. The main goal is to see how often people pass gas and how your diet, especially fiber, influences this. This is an observational study, meaning you'll continue your normal activities while wearing the device for three days. The study plans to include up to 500 adults.
- Study design
- This is an observational study involving up to 500 participants. It does not involve any interventions or treatments.
- What's involved
- You would wear a Smart Underwear device for three consecutive days while continuing your usual daily activities. You would also log dietary information in a mobile app.
- Compensation
- Not stated in the trial record.
- Follow-up
- Not specified.

What this trial measures
- Microbiome Activity Index12 hours each day for 3 days
The Microbiome Activity Index is a composite measure reflecting gut microbiome activity, calculated from both flatus frequency and hydrogen gas concentration. The index uses the absolute value of the first derivative of the hydrogen sensor signal to better capture flatus intensity, reduce baseline noise, and mitigate sensor saturation at high hydrogen levels. This composite approach ensures a more accurate representation of gut microbiome activity than relying on flatus count or hydrogen concentration alone. Data are collected using a wearable device ("Smart Underwear") and uploaded to the Human Flatus Atlas app.
