Dirt floors linked to infant deaths? simple fix could save lives
NCT ID NCT07620613
First seen Jun 25, 2026 · Last updated Jul 02, 2026 · Updated 4 times
Summary
This study tests whether replacing soil floors with concrete floors in rural Bangladeshi homes can reduce stillbirths and deaths in the first month of life. Researchers will compare 196 households that received concrete floors to those that kept soil floors, tracking pregnancies and births for up to 6 years. The goal is to see if a simple, low-cost home improvement can prevent infant deaths.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- concrete floor
- What this could lead to
- If it works, this could show that a simple home improvement—replacing dirt floors with concrete—can save babies' lives in rural areas.
- What could go wrong
- This is an extension of an earlier trial, so results are still preliminary. The study is small (196 participants) and limited to two districts in Bangladesh, so findings may not apply elsewhere.
