Prenatal alcohol exposure and risk of birth defects

This study investigated the association between dose, pattern, and timing of prenatal alcohol exposure (PAE) and birth defects. Compared with abstinence, heavy alcohol use in the first trimester was associated with a fourfold increase in risk of birth defects. The study found no association between low or moderate prenatal alcohol exposure and birth defects.
