A study author Stefanie Hinkle, an assistant professor of epidemiology at University of Pennsylvania School of Medicine suggests that consuming a little caffeine while expecting might not necessarily be a bad thing.
For the study, the researchers looked at prospective data from over 2,500 pregnant participants who were enrolled in a U.S. National Institute of Child Health and Human Development study conducted at 12 U.S. clinical centers between 2009 and 2013. The study measured concentrations of caffeine in the participants’ blood plasma when they were 10 and 13 weeks pregnant, as well as asking women to report weekly intake of caffeinated coffee, tea, soda and energy drinks.
The investigators found that drinking caffeinated beverages at 10 to 13 weeks’ gestation was not related to gestational diabetes risk. Not only that, drinking up to 100 milligrams (mg) of caffeine per day — about one 6-ounce cup — was associated with a 47% reduction in diabetes risk during the second trimester.
The findings were published online recently in JAMA Network Open.
