ABSTRACT
There are no studies that have utilized both biomarkers and self-reported data to evaluate maternal alcohol use during pregnancy in Mexico. Therefore, we aimed to describe the prevalence of alcohol consumption in a cohort of 300 Mexican pregnant women. We used a validated ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method to measure hair ethyl glucuronide (EtG) in hair segments that corresponded to the first and second half of pregnancy. We compared the hair EtG values to a self-reported questionnaire on maternal drinking habits and evaluated whether the gestational alcohol use was associated with psychotropic drug use. Based on the EtG measurements, 263 women (87.7%) were alcohol-abstinent during the entire pregnancy, while 37 (12.3%) had used alcohol at least once during the pregnancy. Of these, only two women were found to have problematic alcoholic behavior during the entire pregnancy. No significant differences in sociodemographic characteristics were observed between alcohol-abstinent women and women with drinking habits. The self-reporting data and hair EtG gave heterogeneous results: although 37 women had self-reported alcohol use during pregnancy, only 54.1% of these women tested positive for hair EtG. Of the women who tested positive for hair EtG, 54.1% tested positive for psychoactive substances. In our cohort, the use of drugs of abuse was independent of gestational drinking. This study provided the first objective evidence of prenatal ethanol consumption in a cohort of Mexican pregnant women.

La exposición prenatal al alcohol es causa de alteraciones somáticas, cognitivas y conductuales que se agrupan bajo el término de trastorno del espectro alcohólico fetal (TEAF). La evolución a largo plazo de los sujetos afectados a menudo es desfavorable, especialmente a nivel académico y adaptativo social. En el perfil neuropsicológico es característica la disfunción ejecutiva a menudo asociada a trastornos de la conducta que evolucionan en muchos casos hacia la delincuencia a partir de la adolescencia y en la edad adulta. Se han descrito también déficits de las habilidades sociales y la empatía. La exposición prenatal al alcohol constituye la causa más frecuente de trastorno del neurodesarrollo adquirido y prevenible.
Prenatal exposure to alcohol is the cause of cognitive and behavioural disorders grouped under the term fetal alcohol spectrum disorders (FASD). The long-term evolution of subjects with FASD is often unfavourable, especially in social and academic fields. Executive dysfunction is a hallmark deficit for children with FASD with increased rates of externalizing behaviours, such as aggressiveness and frequently delinquency in adolescence and adulthood. Deficits in social skills, empathy and communication ability are frequent observed among FASD. Prenatal exposure to alcohol is the most frequent cause of acquired and preventable neurodevelopmental disorder.
