The purpose of the study is to understand the biology and behavior of early mother-infant attachment, and to investigate how it may be affected by prenatal substance exposures. The investigators are interested in how drugs such as cocaine, alcohol, marijuana and cigarette smoking affect both mother and baby.


Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Prenatal Cocaine and Neurobehavioral Factors Underlying Mother-Infant Interaction

Primary Outcome Measures:
  • Determine the effect of prenatal cocaine exposure on the neonatal brain. ventricular volumes [ Time Frame: 2 to 4 weeks of age ]

Biospecimen Retention:   Samples With DNA
Plasma from mothers and buccal cells from infants will be stored for possible DNA analysis of target genes pending additional funding.

Estimated Enrollment: 150

Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Prenatal Cocaine
Use of cocaine at anytime during pregnancy. Subjects may also have used other drugs in combination with Cocaine
Prenatal Nicotine-Alcohol-Marijuana
Subjects may have used any of these drugs during pregnancy, alone or in combination. This group has not used cocaine during pregnancy.
Drug-Free Pregnancy

Subjects did not use any of the following drugs during pregnancy:

cocaine, nicotine, alcohol, marijuana.

Detailed Description:

The investigators are looking for pregnant women or mothers with their newborn infants to participate in this study. Eligible women include mothers who have used any of the following drugs at any time during pregnancy (alone or in combination):

  1. cocaine
  2. nicotine (cigarettes)
  3. marijuana
  4. alcohol

The investigators are also looking for mothers who have not used any drugs during pregnancy.

Information collected in this research study is strictly confidential, and protection of sensitive information is additionally assured by an NIH Certificate of Confidentiality.

Participation in this study involves:

  1. One visit at 2-4 weeks postpartum. This visit includes an interview for mother and a 30 minute brain scan (no radiation, no sedation) for baby.
  2. Two visits at 3 months postpartum. Mothers will have blood pressure and heart rate measured while they look at videos about babies, listen to baby sounds, interact with their own baby. Samples of blood, urine and saliva will be taken from mother. Baby will have a developmental assessment, and saliva samples will be taken.

Payment is $300 or the equivalent in Walmart gift cards for completion of brain imaging, lab visits and 1 day of monitoring mother's blood pressure at home.
