Prevalence of Fatty Acid Ethyl Esters in Meconium Specimens

Fetal alcohol syndrome (FAS), alcohol-related birth defects (ARBDs), and alcohol-related neurodevelopment disorders (ARNDs) in neonates are often the result of maternal alcohol consumption during pregnancy. Facial characteristics are associated with FAS, but ARBDs and ARNDs are more difficult to diagnose. Fetal exposure to alcohol can cause central nervous system dysfunction, pre- and postnatal growth problems, cardiac defects in neonates, and attention deficit disorders and mental retardation in older children. To date, diagnosis of fetal alcohol effect has depended largely on maternal interview, although clinical tests are becoming more widely used. Fatty acid ethyl esters (FAEEs) are formed in the body by esterification of ethanol with free fatty acids and trans-esterification of glycerides and have been detected in the meconium of newborns. This report estimates the prevalence of fetal alcohol exposure in two populations by detecting FAEEs in meconium.
