Teens Who Were Exposed to Alcohol Before Birth are More Likely to Drink Hazardously and Engage in Risky Sexual Behavior, According to a Large UK Study

Teens who were exposed to alcohol in utero are more likely than their peers to engage in risky behaviors--most notably, hazardous drinking and underage sex, a combination that could perpetuate the intergenerational transmission of prenatal alcohol exposure (PAE). The UK has one of Europe's highest rates of alcohol use during pregnancy: at least 41%, potentially reaching 75%. PAE increases the risk of fetal alcohol spectrum disorder, a range of neurodevelopmental impairments. In adolescence, these may manifest as impulsivity, difficulties in making judgments, and social struggles, sometimes extending to sexual inappropriateness, substance dependence, aggression, criminality, and/or difficulties with independent living. For the study in Alcohol: Clinical & Experimental Research, British investigators examined the impact of PAE on multiple risky behaviors in teens.
