Study Center: Iowa

The Iowa Center collaborates with the Iowa Registry for Congenital and Inherited Disorders (IRCID) to identify children with birth defects in Iowa. Since 1983, the Iowa Registry has monitored birth defects in all 99 Iowa counties. The Iowa Center was established in 1996 and enrolled families statewide in the NBDPS. Iowa families have been very willing to participate in the NBDPS. This participation provides the opportunity to study risk factors for birth defects among a rural population.

Principal Investigator

Paul Romitti, PhD, is a Professor of Epidemiology in the College of Public Health at The University of Iowa and IRCID Director. Dr. Romitti leads the Iowa Center and directs the interview and sample collection and epidemiologic and gene-environment data analyses for the Center. Dr. Romitti also leads the NBDPS research group to study the effects of tobacco, alcohol, caffeine and illicit drugs on birth defects and is examining the impact of pesticide exposure on birth defects.

Local Activities and Research

  • Study tobacco and alcohol use and nutrition as risk factors for birth defects
  • Examine the link between pesticide exposure and birth defects
  • Study the effects of compounds in drinking water and birth defects
  • Identify possible genetic risk factors for birth defects
  • Understand the long-term outcomes among children with birth defects
