Alcohol exposure during pregnancy affects multiple generations.

Alcohol exposure during pregnancy affects multiple generations. When a mother drinks alcohol during pregnancy, even a small dose, she can increase the chances that the next three generations may develop alcoholism, according to a new study.

A research team led by Nicole Cameron, PhD, was the first to investigate the effects of alcohol consumption during pregnancy on alcohol-related behavior (consumption and sensitivity to the effect of alcohol) on generations that were not directly exposed to alcohol in the uterus during the pregnancy.

Pregnant rats received the equivalent of one glass of wine, four days in a row, at gestational days 17-20, which is the equivalent of the second trimester in humans. Juvenile male and female offspring were then tested for water or alcohol consumption. Adolescent males were tested for sensitivity to alcohol by injecting them with a high-alcohol dose, which made them unresponsive, and measuring the time it took them to recover their senses. The results suggest that if a mother drinks during pregnancy, even just a little, she increases the risk that her progeny will become alcoholic.
