Caffeine and pregnancy outcome.

B Worthington-Roberts, A Weigle

JOGN Nursing; Journal of Obstetric, Gynecologic, and Neonatal Nursing

|January 1, 1983

Summary

This summary is machine-generated.

Caffeine readily crosses the placenta, potentially posing risks to fetal development. While human studies are inconclusive, pregnant women are advised to limit caffeine consumption to ensure fetal safety.

Background:

Caffeine is a widely consumed psychoactive substance.
It easily crosses the placental barrier, reaching fetal circulation.
Existing research on teratogenic effects primarily relies on animal models.

Purpose of the Study:

To review the existing literature on caffeine's effects during pregnancy.
To assess the potential risks of caffeine exposure to fetal development.
To provide guidance for pregnant women regarding caffeine intake.

Main Methods:

Literature review of studies investigating caffeine and pregnancy outcomes.
Analysis of animal model data on caffeine teratogenicity.
Evaluation of human epidemiological studies on caffeine consumption and fetal development.

Main Results:

Caffeine demonstrably crosses the placental barrier.
Animal studies indicate potential teratogenic effects.
Definitive teratogenic relationships in humans remain unconfirmed by current evidence.

Conclusions:

Pregnant women should consider limiting or discontinuing caffeine intake.
Further research is needed to definitively establish human risks.
Reducing maternal caffeine consumption is a precautionary measure for fetal well-being.
