Abstract
Objective
Estimation of the maternal caffeine intake during pregnancy and its influence on pregnancy
duration, birthweight and Apgar score of the newborn.
Study design
The research was conducted on pregnant women who gave birth at the Clinic of Obstetrics,
Gynaecology and Oncology, 2nd Faculty of Medicine, Medical University of Warsaw. It
covered unifetal pregnancies without diseases (N = 509). Research data were collected by direct questionnaire supplemented with data
from patients’ records. Statistical analysis employed a multivariate logistic regression
model and a non-parametric Spearman's rank correlation coefficient.
Results
98.4% of pregnant women consume no more than 300 mg of caffeine per day. Pregnant women who smoke and older women consume more caffeine
than non-smokers and younger women [β 1.95 (95% CI: 1.02–2.88)] and [β 0.68 (95% CI:
0.05–1.3)] respectively. There is no association between maternal caffeine intake
during pregnancy and the risk of premature birth, the birthweight or the Apgar score
of newborns.
Conclusion
Caffeine intake of no more than 300 mg per day during pregnancy does not affect pregnancy duration and the condition of
the newborn.
