Limited coffee consumption during pregnancy would not lead to an increased risk of miscarriage, stillbirth or premature birth, according to a new study by researchers from the Institute for Molecular Bioscience at the University of Queensland.[1] The study was published inInternational Journal of Epidemiology.[2]

There are genetic variants that can affect the coffee we drink

Gunn-Helen Moen, one of the researchers involved in the study, explains that the purpose of the research was to find out whether coffee alone (thus excluding other risk factors) can really increase the risk of certain negative pregnancy outcomes.
Daniel Hwang, another Australian university researcher working on the study, explains that there are several genetic variants that can affect the amount of coffee we drink. The researcher explains that the study results indicate that the previously mentioned genetic variants also apply to pregnant women.[1]

I study

Using a Mendelian randomization method, the researchers focused on eight genetic variants, a useful method because, as Hwang explains, it is not possible to perform an experiment that requires women to drink certain amounts of coffee during pregnancy.
Genetic analysis indicated that there was no increased risk of miscarriage, stillbirth or premature birth for the women who usually drank coffee during pregnancy. According to Hwang, the study shows that women “can still enjoy coffee without worrying about increasing the risk of these pregnancy outcomes.”[1]

High consumption of coffee during pregnancy is still not advisable

However, the researchers explain that only certain negative outcomes that can occur during pregnancy or childbirth have been taken into account. It is still possible, in addition to the results of this study, that caffeine consumption may have an impact on other aspects of fetal development. That is why, explains Moen, a high consumption of coffee during pregnancy is still not recommended. However, low or moderate consumption is still recommended.[1]
