Alcohol consumption, low birth weight, and preterm delivery in the National Addiction Survey (Mexico).

In 1988 the Mexican General Directorate of Epidemiology and the Mexican Institute of Psychiatry carried out the first National Addiction Survey that provided prevalence estimates at national and regional levels of alcohol consumption, tobacco smoking, and several other drugs use. In addition, a questionnaire included questions regarding alcohol consumption during pregnancy and adverse outcomes. According to the results of logistic regression, women classified as suffering from Alcohol Dependence Syndrome had a very high risk of low birth weight and/or preterm delivery: Odds ratio = 12.1 with a 95% confidence interval of (1.3, 108.9) and p = .026. After controlling for several confounding variables, the findings remained basically the same.
