Alcohol during pregnancy: no safe amount

Updated Six Habits Editorial Team
The short answerAlcohol during pregnancy can cause fetal alcohol spectrum disorders (FASDs), lifelong problems with development, learning and behavior. Globally, about 10% of women drink during pregnancy, and fetal alcohol syndrome, the most severe form, occurs in about 15 of every 10,000 children. No safe amount or safe time to drink during pregnancy has been established.

Key points

What the research shows

A global systematic review and meta-analysis estimated that about 10% of women drink alcohol during pregnancy. The prevalence of fetal alcohol syndrome was about 15 per 10,000 people, and about 1 in 67 women who drank during pregnancy delivered a child with fetal alcohol syndrome (Popova et al., 2017). In the U.S., CDC surveys find that about 1 in 7 pregnant women report drinking and about 1 in 20 report binge drinking.

What FASDs are

Fetal alcohol spectrum disorders include fetal alcohol syndrome and other conditions affecting:

The effects are lifelong, but early diagnosis and support improve outcomes.

Recommendation

There is no known safe amount, type or time of alcohol use during pregnancy. If you are pregnant or could become pregnant, the safest choice is not to drink. Alcohol is also a carcinogen for adults (Bagnardi et al., 2015).

Frequently asked questions

Is an occasional glass of wine OK?

The CDC, the U.S. Surgeon General and ACOG all advise no alcohol during pregnancy, because no safe amount has been established.

What about when trying to conceive?

Because pregnancy is often not recognized for several weeks, the CDC advises avoiding alcohol when you could be pregnant.
