To reduce the risk of alcohol-related birth defects, several measures can be taken. Firstly, pregnant women should abstain from alcohol consumption entirely [1][2]. This is because alcohol can cause a range of birth defects, collectively known as Fetal Alcohol Spectrum Disorders (FASDs) [2]. FASDs can include physical, behavioral, and learning problems, with the most severe form being Fetal Alcohol Syndrome (FAS) [2].

Secondly, women planning to become pregnant should also avoid alcohol [2]. This is because alcohol can harm the developing fetus even before a woman knows she is pregnant [2]. The risk of FASDs increases with the amount and frequency of alcohol consumption [2].

Thirdly, healthcare providers should educate women about the risks of alcohol consumption during pregnancy [1][2]. They should advise women to abstain from alcohol if they are pregnant, planning to become pregnant, or if there is a chance they could be pregnant [2].

Lastly, public health initiatives can play a role in reducing alcohol-related birth defects. These can include public awareness campaigns about the risks of alcohol consumption during pregnancy, as well as policies to reduce alcohol availability and promote responsible drinking [1][2].

In summary, the measures to reduce alcohol-related birth defects include abstaining from alcohol during pregnancy and while planning to become pregnant, educating women about the risks, and implementing public health initiatives.
