Prenatal drug exposure and maternal and infant feeding behaviour.

OBJECTIVE: To evaluate feeding difficulties and maternal behaviour during a feeding session with 1 month old infants prenatally exposed to cocaine and/or opiates. METHODS: The study is part of the maternal lifestyle study, which recruited 11 811 subjects at four urban hospitals, then followed 1388 from 1 to 36 months of age. Exposure to cocaine and opiates was determined by maternal interview and meconium assay. At the 1 month clinic visit, biological mothers were videotaped while bottle feeding their infants. This sample included 364 exposed to cocaine, 45 exposed to opiates, 31 exposed to both drugs, and 588 matched comparison infants. Mothers were mostly black, high school educated, and on public assistance. Videotapes were coded without knowledge of exposure status for frequency, duration and quality of infant sucking, arousal, feeding problems, and maternal feeding activity and interaction. RESULTS: No cocaine effects were found on infant feeding measures, but cocaine-using mothers were less flexible (6.29 v 6.50), less engaged (5.77 v 6.22), and had shorter feeding sessions (638 v 683 seconds). Opiate exposed infants showed prolonged sucking bursts (29 v 20 seconds), fewer pauses (1.6 v 2.2 per minute), more feeding problems (0.55 v 0.38), and increased arousal (2.59 v 2.39). Their mothers showed increased activity (30 v 22), independent of their infants' feeding problems. CONCLUSIONS: Previous concerns about feeding behaviour in cocaine exposed infants may reflect the quality of the feeding interaction rather than infant feeding problems related to prenatal exposure. However, opiate exposed infants and their mothers both contributed to increased arousal and heightened feeding behaviour.

Central and autonomic system signs with in utero drug exposure.

AIMS: To determine risk for central nervous system/autonomic nervous system (CNS/ANS) signs following in utero cocaine and opiate exposure. METHODS: A multisite study was designed to determine outcomes of in utero cocaine and opiate exposure. A total of 11 811 maternal/infant dyads were enrolled. Drug exposed (EXP) infants were identified by maternal self report of cocaine or opiate use or by meconium testing. Of 1185 EXP, meconium analysis confirmed exposure in 717 to cocaine (CO) only, 100 to opiates (OP), and 92 to opiates plus cocaine (OP+CO); 276 had insufficient or no meconium to confirm maternal self report. Negative exposure history was confirmed in 7442 by meconium analysis and unconfirmed in 3184. Examiners masked to exposure status, assessed each enrolled infant. Using generalised estimating equations, adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated for manifesting a constellation of CNS/ANS outcomes and for each sign associated with cocaine and opiate exposure. RESULTS: Prevalence of CNS/ANS signs was low in CO, and highest in OP+CO. Signs were significantly related to one another. After controlling for confounders, CO was associated with increased risk of manifesting a constellation of CNS/ANS outcomes, OR (95% CI): 1.7 (1.2 to 2.2), independent of OP effect, OR (95% CI): 2.8 (2.1 to 3.7). OP+CO had additive effects, OR (95% CI): 4.8 (2.9 to 7.9). Smoking also increased the risk for the constellation of CNS/ANS signs, OR (95% CI) of 1.3 (1.04 to 1.55) and 1.4 (1.2 to 1.6), respectively, for use of less than half a pack per day and half a pack per day or more. CONCLUSION: Cocaine or opiate exposure increases the risk for manifesting a constellation of CNS/ANS outcomes.

The Maternal Lifestyle Study: drug use by meconium toxicology and maternal self-report.

OBJECTIVE: The objective of this study was to describe drug use by pregnant women participating in the 4-site Maternal Lifestyle Study of in utero cocaine and/or opiate exposure. METHODS: Meconium specimens of 8527 newborns were analyzed by immunoassay with GC/MS confirmation for metabolites of cocaine, opiates, cannabinoids, amphetamines, and phencyclidine. Maternal self-report of drug use was determined by hospital interview. RESULTS: The prevalence of cocaine/opiate exposure in the 4 sites was 10.7% with the majority (9.5%) exposed to cocaine based on the combination of meconium analysis and maternal self-report. However, exposure status varied by site and was higher in low birth weight infants (18.6% for very low birth weight and 21.1% for low birth weight). Gas chromatography/mass spectrometry (GC/MS) confirmation of presumptive positive cocaine screens was 75.5%. In the cocaine/opiate-exposed group, 38% were cases in which the mother denied use but the meconium was positive. There was 66% agreement between positive meconium results and positive maternal report. Only 2% of mothers reported that they used only cocaine during pregnancy and mothers were 49 times more likely to use another drug if they used cocaine. CONCLUSION: Accurate identification of prenatal drug exposure is improved with GC/MS confirmation and when the meconium assay is coupled with a maternal hospital interview. However, the use of GC/MS may have different implications for research than for public policy. We caution against the use of quantitative analysis of drugs in meconium to estimate the degree of exposure. Our study also highlights the polydrug nature of what used to be thought of as a cocaine problem.

Using administrative data to reward agency performance: the case of the federal adoption incentive program.

This article explores the history of the federal Adoption Incentive Program, the first federal child welfare outcome-based incentive program to rely solely on administrative data, and discusses it within the context of other prior and ongoing federal child welfare incentive programs. Various data-related issues are also examined, including the use of data to project program utilization and costs, set baselines for the number of adoptions, and award funds. Challenges in the legislatively required use of AFCARS data for determining the amount of incentive funds awarded and the impact of the program on AFCARS reporting are also discussed. The article concludes with a look at the impact of the Adoption Incentive Program on adoption and predictions for the future.

Boarder babies and placement in foster care.

This article describes the early history of the "boarder baby" phenomenon through the late 1980s and early 1990s. The characteristics of the recent "boarder baby" population and of the problem are described with particular emphasis on the role of alcohol and drug abuse and the historical lack of coordination between hospitals and child welfare agencies. Three additional topics are discussed in depth: (1) policies around testing mother and infants, (2) the meaning and use of a positive toxicology screen for a newborn or birthing mother, and (3) the identification and characterization of the victim. Alternative solutions to the problem are discussed.

Central and autonomic nervous systems' signs associated with in utero exposure to cocaine/opiates.

In summary, we found that the prevalence of CNS/ANS signs was significantly higher in the infants exposed to cocaine and/or opiates than in nonexposed infants. However, the prevalence of a large number of these signs was less than 5%. The prevalence rates of these signs are lower when exposure involved cocaine only; thus, their assessment has limited clinical utility.
