Primary Outcome Measures:
  • Neurobehavioral development [ Time Frame: 1 to 12 years ]
  • Asthma [ Time Frame: 2-12 years ]

Biospecimen Retention:   Samples With DNA
We collected maternal urine during the third trimester of pregnancy, maternal blood at delivery, umbilical cord blood, meconium, blood and urine from the child at ages 24, 36, and 60 months.

Enrollment: 727
Study Start Date: August 1997
Study Completion Date: May 2013
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Detailed Description:
The major objective of the proposed research is to study the impact of early-life exposures to common urban pollutants on neurobehavioral development and asthma in a sample of children living in three low-income, minority communities of New York City (Central Harlem, Washington Heights and the South Bronx). Using a molecular epidemiologic approach with monitoring, biomarkers, and clinical assessments at serial time points, we will extend our study of African-American and Latina urban mothers and children in order to follow the cohort through child age 11 years to assess the longer-term impact of exposures on child health and developmental outcomes.

Ages Eligible for Study:   18 Years to 35 Years   (Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
The present study enrolled 727 African American and Latino (Dominican) mothers and their children. The African American and Latino (Dominican) women were initially enrolled into the parent CCCEH study during pregnancy. Caucasian women are not included because a central purpose of the research is to evaluate health outcomes in a high risk, minority population.
Enrollment eligibility was restricted to nonsmoking pregnant women 18-35 years of age who self-identified as either African American or Dominican and who had resided in northern Manhattan or the South Bronx in New York City for at least 1 year before pregnancy. Women were excluded if they used illicit drugs, had diabetes, hypertension, or known HIV, or had their first prenatal visit after the 20th week of pregnancy.
