title: Results of 313 consecutive live births of infants delivered to patients in the New York City Methadone Maintenance Treatment Program.
abstract: Patients characteristics, birth results, and follow-up status are described for the first 313 babies born live to patients on the Methadone Maintainance Treatment Program operated by the New York Department of Health. Data were derived from the birth certificates and methadone clinic and hospital records. Comparisons with reports in the literature are noted. No significant association was found between maternal dosage of methadone in the last trimester of pregnancy and lentth of gestation, birth weight, or the reported presence of withdrawal symptoms in the neonate. The infant mortality rate was identical to the over-all New York City rate, specific for ethnicity. After an average of 6 1/2 months following delivery, 86 per cent of the mothers remained on the program.
