In a new finding, researchers from the Nationwide Children’s Hospital in Columbus have revealed that caffeine consumption by expectant mothers is safe at least when it comes to child’s intelligence. According to researchers, drinking moderate coffee during pregnancy do not affect baby’s IQ as they haven’t found any direct evidence or regular pattern that interlinks coffee consumption with baby’s intelligence.

“We did not find evidence of an adverse association of maternal pregnancy caffeine consumption with child cognition or behavior at four or seven years of age,” said principal investigator Mark A. Klebanoff.

For the study, researchers observed caffeine blood samples of 2,197 pregnant women who participated in the Collaborative Pernatal Project conducted at multiple sited in the US between 1959 and 1974. According to researchers, in those 15 years coffee consumption among expectant mothers was highest as very few considered it harmful for baby’s intelligence. Thus, study authors were able correlate adverse effects of coffee and cognitive functions in a better way.

Researchers checked levels of paraxanthine, caffeine’s primary metabolite twice during pregnancy and then compared it with the baby’s intelligence at the age of four and again at seven. After analysing the data, it was clear that coffee consumption during pregnancy and IQ of the baby has no direct interlink since no regular pattern was observed in the same.

In addition, some said that coffee intake induces obesity in the child. However, previous study conducted by Dr Klebanoff and Dr Sarah Keim at Nationalwide Children’s Hospital also found that increased coffee intake had no effect on child’s health and it did not induce obesity. Only 11 percent of the child were diagnosed as obese at the age of four while seven percent were considered obese at the age of seven but no regular pattern was found between caffeine intake and childhood obesity.

Dr Keim said: ‘Taken as a whole, we consider our results to be reassuring for pregnant women who consume moderate amounts of caffeine or the equivalent to one to two cups of coffee a day.’

In general, coffee during pregnancy is considered bad for child’s health. Thus, it is advised to the expectant mother to stop drinking coffee until the child is born. Moreover, some studies have found that coffee affects heartbeat of the baby while some say that it might lead to miscarriage.
