Substance abuse during pregnancy in a rural population.

Drug abuse during pregnancy in rural populations has received less attention than that in urban populations. Urban studies have reported alarming rates, but it is unknown whether the situation is the same in rural areas. To investigate this, urine samples were collected anonymously from 181 pregnant women who presented to the University of Missouri clinics for care and who resided in communities of less than 25,000. Each urine specimen was tested for cocaine, marijuana, amphetamines, barbiturates, opiates, phencyclidine, benzodiazepines, ethanol, and nicotine. Of the 181 specimens, 83 (46%) contained nicotine, 17 (9.4%) contained marijuana, and one each (0.6%) tested positive for cocaine, barbiturates, ethanol, and benzodiazepines. No other tested substances were detected. Excluding nicotine and ethanol, 20 (11%) of the urine samples tested positive for the screened substances. Review of the prenatal records revealed that 46% of the women reported using tobacco, 15% reported using alcohol, and 8.3% reported illicit drug use during pregnancy. This study indicates that there is a substantial drug abuse problem in rural populations, and that the profile of abuse differs from that of urban populations. Tobacco, ethanol, and marijuana were the most prevalent substances abused during pregnancy, but cocaine was a minor problem. This information may help in directing resources to reduce drug abuse during pregnancy.
