Vitamin d in pregnancy may shape Child's lung health
NCT ID NCT03229317
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether low vitamin D levels in early pregnancy are linked to breathing problems in children ages 5 to 6. Researchers measured airway resistance in 142 children whose mothers had vitamin D levels checked during the first trimester. The goal is to understand if vitamin D plays a role in early lung development and later asthma risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If it works, this could point toward a role for vitamin D in early lung development and asthma prevention.
- What could go wrong
- This is an observational study, not a treatment trial. It only looks for an association, so it cannot prove cause and effect.
