Coffee does not affect pregnancy

Scientists at the American College of Obstetrics and Gynecology (ACOG) in New York on July 21 said drinking a cup of coffee every day during pregnancy did not increase the risk of miscarriage or premature birth.

Scientists have looked at two recent studies on the effects of caffeine on women during pregnancy. The first study was conducted by Dr. David Savitz of The Mount Sinai Medical Center in New York for 1,000 pregnant women.

As a result, no increased risk of miscarriage was found in pregnant women who drank a little, relatively or more coffee at different times during pregnancy.

The second study, conducted by Dr. De-Kun Li and colleagues at a research institute in Oakland, also found that there was no increased risk of miscarriage in pregnant women who drank more than 200mg of caffeine daily.

In addition, ACOG scientists have also studied other experiments and have not found an increased risk of premature birth in women who drink coffee during pregnancy.

Until recently, studies still had different conclusions about the effects of caffeine on pregnancy complications. Previously, a study jointly conducted by US and Norwegian scientists said that women who took three cups of coffee during the first three months had a risk of birth defects of 1.39 times.

If drinking more than three cups of coffee per day, this risk will increase to 1.59 times. Especially, people who have prenatal caffeinated drugs often have a 50-fold increase in risk.

Scientists are still unable to explain the mechanism of coffee's impact on fetal development. The full study of this influence is difficult because the use of coffee is often related to other factors such as smoking, drinking alcohol, beer .

In the United States, about 16% of all pregnancies are miscarriage and about 12% are premature.
