Pregnancy Caffeine Safety: Low Birth Weight Risk Meta-Analysis
Dr. Kumar’s Take
This large meta-analysis provides evidence that higher maternal caffeine intake is associated with an increased risk of low birth weight. The relationship is dose-dependent, suggesting that even moderate daily caffeine exposure may affect fetal growth. These findings support maintaining conservative intake limits during pregnancy.
Key Takeaways
- Maternal caffeine intake shows a dose-dependent association with low birth weight.
- Risk increases gradually above 200 mg/day.
- Findings are consistent across multiple cohorts and countries.
- Supports existing recommendations to limit intake below 200 mg/day in pregnancy.
Actionable Tip
Pregnant individuals should limit caffeine intake to ≤200 mg/day, roughly equivalent to one 12-ounce cup of coffee, and account for caffeine in tea, soda, and chocolate.
