The Environmental Public Health Tracking (EPHT) Program is the first national effort to create a network to provide the United States with standardized data integrated from multiple hazard, exposure, and health effects information systems. Limited Birth Record Data from the Oregon Center of Health Statistics (CHS) Database are available on the National EPHT Network and on the Oregon EPHT website at http://www.oregon.gov/DHS/ph/epht. The Oregon EPHT Birth Record dataset contains categorical information about births to resident mothers including infant sex, birthweight, prenatal care, Apgar 5 score, birth expense payor, selected birth defects (anencephalus, cleft lip-palate, Down syndrome, spina bifida), and maternal race, ethnicity, age group, and education. Counts and percentages are available for births occurring after 1996, by state, county and year. Data from the EPHT network may be used to attempt to quantify the magnitude of environmental health problems, detect unusual trends and occurrences, document the distribution and spread of a hazard or health event, identify populations at risk, plan and evaluate protective and preventive measures, facilitate research, and detect the results of changes in health practices. The Oregon EPHT Program is part of a National EPHT Network sponsored by the CDC. The Oregon EPHT Program resides in the Toxicology, Assessment, and Tracking Section of the Office of Environmental Public Heath (OEPH) which is in the Public Health Division of the Department of Human Services (DHS).
The purpose of the Oregon EPHT Program is to provide scientific information from a web-based network of hazard, exposure, and health effect data to support actions that improve the health of communities. By bringing together, and standardizing, local, state, and national data sources of environmental and health information, scientists, policymakers, and the public will be able to more effectively address fundamental questions about relationships between environmental exposures and health effects.

The Center for Health Statistics (CHS) is responsible for maintaining all Oregon birth records. Oregon EPHT makes no representation or warranties regarding the completeness of data.
The Center for Health Statistics (CHS) is responsible for maintaining approximately 6 million vital records. Birth and death records have been filed with the state since 1903. Marriage records have been filed since 1906, divorce records since 1925, and fetal death records since 1919. Oregon law requires that vital events such as births, marriages, divorces, and deaths be recorded and registered. CHS is also responsible for compiling and analyzing the data from vital records. These data are used throughout the state and nation for program planning and policy development and are the primary data sources used for measuring many Oregon health benchmarks. Birth certificates are not public record and access to the data requires approval by State Registrar. Access to birth records is restricted for 100 years to the registrant, immediate family members and legal representatives (includes legal guardians or persons with power of attorney), and persons licensed in Oregon under ORS 703.430. Government agencies may order if the records are needed in the course of their work, or to prevent fraud. When ordering a birth certificate, you must state your relationship to the person on the record; if you are an attorney, you must state whom you represent. If you are a legal guardian or have power of attorney, you must enclose a copy of the legal document. Each request for vital records is screened for eligibility before the certified copy is produced.
The Oregon Center for Health Statistics provides EPHT with secure access to de-identified Birth Record Data. Oregon EPHT categorizes the data and aggregates by county, and year. Suppression rules are used to prevent specific data from being used to identify a particular individual. Suppression rules only apply to certain cells depending on time resolution, query and field (sensitive or not). Suppression applies if data are aggregated over less than 3 years (i.e., Most Recent Year OR Annual Trend over years OR Multiple Year Summary with Year Count <3) and the cell contains data from one of the following queries and specific subcategories from the listed fields. For Birth Record data suppression rules apply if the cell contains a measure specific to one of the following subcategories or aggregate of subcategories less than All (i.e. 'All selected categories' in the output): Birth weight, Apgar 5 Score, Prenatal Care Index, and Payor (any category except Unknown). Suppression rules apply for all Birth Defect queries, i.e. independently of characteristics selections If suppression applies, data will not be shown (count, rate, %) for a cell if the count for the cell (or numerator for rate) is less than 11 or the denominator population is less than 51. Rate estimations based on small case counts may be unstable. Independently of the user's selections, rates are flagged if based on a count (numerator) of less than 10.
