Kind: research · Impact: medium

## In brief

- A new study presented at the American College of Allergy, Asthma and Immunology links wildfire smoke and other air pollution during the middle and later months of pregnancy to higher asthma rates in young children.
- The reported finding is an association: babies whose mothers breathed wildfire smoke and other air pollution in mid and late pregnancy were more likely to develop asthma as young children.
- The source is a summary of a conference presentation, so the findings are preliminary and not yet peer-reviewed in the material provided.

## Why it matters

Prenatal exposure to wildfire smoke and air pollution may be an early risk factor for childhood asthma, which is relevant to exposure assessment and public health planning for pregnant people in fire-prone regions.
