Scientists from the University of Cambridge found that drinking coffee during pregnancy did not increase the risk of premature birth, while smoking was associated with a 2.6-fold increase in risk. The study was published on: International Journal of Epidemiology.
More than 4,200 women in the UK took part in the study between 2008 and 2012. The scientists analyzed blood samples taken from the patients four times during pregnancy.
To assess the effects of cigarette smoke, they looked at levels of the substance cotinine. Of the 914 women included in the analysis of the effects of smoking, almost 79% were nonsmokers during pregnancy, approximately 12% were occasional smokers, and 10% were regular smokers. Only two of the three women with high cotinine levels were smokers. This means that others may also experience second-hand smoke.
Compared with women who did not smoke during pregnancy, those who smoked throughout pregnancy were 2.6 times more likely to give birth prematurely and four times more likely to experience fetal growth restriction. The latter carries a risk of potentially serious complications, including difficulty breathing and infections. Babies born to smokers weighed an average of 387 grams less than babies born to non-smokers; This means they are about 10% lighter than the average newborn.
To assess caffeine intake, researchers used the metabolite paraxanthine. High caffeine intake from coffee or other beverages did not affect the risk of preterm birth or other adverse pregnancy outcomes. This contradicts some previous research that found caffeine was associated with low birth weight and possibly reduced fetal growth.
