The National Birth Defects Prevention Study (OMB 0920-0010)—Extension—National Center on Birth Defects and Developmental Disabilities (NCBDDD), Centers for Disease Control and Prevention (CDC).
Background and Brief Description
The National Birth Defects Prevention Study has been monitoring the occurrence of serious birth defects and genetic diseases in Atlanta since 1967 through the Metropolitan Atlanta Congenital Defects Program (MACDP). The MACDP is a population-based surveillance system for birth defects in the 5 counties of Metropolitan Atlanta. Its primary purpose is to describe the spatial and temporal patterns of birth defects occurrence and serve as an early warning system for new teratogens. From 1993 to 1996, DBDDD conducted the Birth Defects Risk Factor Surveillance (BDRFS) study, a case-control study of risk factors for selected birth defects. Infants with birth defects were identified through MACDP and maternal interviews, and clinical/laboratory tests were conducted on approximately 300 cases and 100 controls per year. Controls were selected from among normal births in the same population. In 1997 the BDRFS became the National Birth Defects Prevention Study (NBDPS). The major components of the study did not change.
The NBDPS is a case-control study of major birth defects that includes cases identified from existing birth defect surveillance registries in ten states (including metropolitan Atlanta). Control infants are randomly selected from birth certificates or birth hospital Start Printed Page 11419records. Mothers of case and control infants are interviewed using a computer-assisted telephone interview. Parents are asked to collect cheek cells from themselves and their infants for DNA testing. Information gathered from both the interviews and the DNA specimens will be used to study independent genetic and environmental factors as well as gene-environment interactions for a broad range of carefully classified birth defects.
The program is requesting approval for an additional three years. There is no cost to the respondent other than their time. The total estimated annualized burden hours are 600.
|Instrument||Number of respondents||Frequency of response||Average burden/response (in hours)|
|NBDPS case/control interview||400||1||1|
|Biologic specimen collection||1,200||1||10/60|
