Clinical descriptions of patients with Fetal Alcohol Syndrome (FAS) and Fetal Alcohol Effects (FAE) suggest major problems with adaptive behavior. Five operationally defined adverse outcomes and 18 associated risk/protective factors were examined using a Life History Interview with knowledgeable informants of 415 patients with FAS or FAE (median age 14 years, range 6-51; median IQ 86, range 29-126). Eighty percent of these patients were not raised by their biological mothers. For adolescents and adults, the life span prevalence was 61% for Disrupted School Experiences, 60% for Trouble with the Law, 50% for Confinement (in detention, jail, prison, or a psychiatric or alcohol/drug inpatient setting), 49% for Inappropriate Sexual Behaviors on repeated occasions, and 35% for Alcohol/Drug Problems. The odds of escaping these adverse life outcomes are increased 2- to 4-fold by receiving the diagnosis of FAS or FAE at an earlier age and by being reared in good stable environments.

Fetal alcohol syndrome is a specific recognizable pattern of malformation. Manifestations in 61 adolescents and adults suffering from alcohol teratogenesis are presented. After puberty, the faces of patients with fetal alcohol syndrome or fetal alcohol effects were not as distinctive. Patients tended to remain short and microcephalic, although their weight was somewhat closer to the mean. The average IQ was 68, but the range of IQ scores widely varied. Average academic functioning was at the second- to fourth-grade levels, with arithmetic deficits most characteristic. Maladaptive behaviors such as poor judgment, distractibility, and difficulty perceiving social cues were common. Family environments were remarkably unstable. Fetal alcohol syndrome is not just a childhood disorder; there is a predictable long-term progression of the disorder into adulthood, in which maladaptive behaviors present the greatest challenge to management.

This longitudinal, prospective, population-based study examined the long-term effects of moderate prenatal alcohol exposure on 482 school aged children. Maternal reports of alcohol use obtained during pregnancy were significantly related to child IQ, achievement test scores, and classroom behaviors in second grade children, even after statistical adjustment for appropriate covariates. Consumption of two drinks per day or more on the average was related to a 7-point decrement in IQ in 7-year-old children even after statistically adjusting for appropriate covariates. Low paternal education and more children in the household were identified as environmental factors exacerbating the effect of prenatal alcohol exposure on child IQ. Learning problems were associated with the alcohol "BINGE" pattern of five or more drinks on at least one occasion. This study shows that alcohol use patterns within the social drinking range can have long lasting effects on IQ and learning problems in young school aged children. These patterns should not be interpreted as biologic thresholds. It should also be noted that these are group effects of prenatal alcohol exposure, not necessarily predictable in the individual child, and that for the most part these children were functioning within the normal range of intelligence.
