Aspiring parents should both avoid drinking alcohol prior to conception to protect against congenital heart defects, according to research published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). Drinking alcohol three months before pregnancy or during the first trimester was associated with a 44% raised risk of congenital heart disease for fathers and 16% for mothers, compared to not drinking. Binge drinking, defined as five or more drinks per sitting, was related to a 52% higher likelihood of these birth defects for men and 16% for women. The data cannot be used to define a cut-off of alcohol consumption that might be considered safe.
