Prenatal substance abuse in California: findings from the Perinatal Substance Exposure Study.
This article reports the overall statewide findings of an epidemiological study that included 29,494 pregnant women who had been admitted for delivery in more than 200 hospitals in California and who were tested for alcohol and other drugs via blind urine toxicology screens. Results were matched to demographic data. The article includes analysis and discussion of four major variables: race/ethnic group differences, acculturation, source of payment for birth, and prenatal care status. Regional results are also discussed. The authors emphasize the high rate of alcohol use and self-reported tobacco use in comparison to relatively low rates of illicit drug use. Alcohol use rates were fairly stable, while use of illicit drugs and tobacco tended to vary according to social and demographic variables. The findings establish the need for both broad-based and targeted prevention and intervention programs to better disseminate the risks involved in drinking alcohol, smoking tobacco, and using drugs during pregnancy.
