The analysis of scientific researches shows that the problem of alcohol consumption (beer, dry wine, champagne), in small doses during pregnancy has been actually disregarded for many years. So the problem has become quite urgent, especially in Russia. In order to determine the effect of alcohol on pregnancy and childbirth, women and babies were divided into three groups. Group 1 (n = 101) (control group) included women who did not use alcohol during pregnancy. Group 2 (n = 75) included drinking women whose alcohol consumption during pregnancy was less than 2 doses or 750 ml. Group 3 (n = 33) included moderately drinking women whose alcohol consumption during pregnancy ranged from 3 to 11 doses (from 750 ml to 3850 ml). The study of the lipid peroxidation-antioxidant protection system as a sensitive marker of integrated health disorders in women, consuming alcoholic beverages in a prenatal period, was conducted. It was indicated that a statistically significant decrease in overall antioxidant activity was found in the context of lipid peroxidation activation in women consuming low-alcohol drinks, which demonstrates a lack of functioning of lipid peroxidation system and oxidative stress regardless of the dose of low-alcohol drinks.
