Mind the gap: bridge methods to allocate multiple-race mothers in trend analyses of birth certificate data.

OBJECTIVES: To examine the effects of proposed methods of redistributing multiple-race mothers to single-race categories when computing trend data from birth certificates. METHODS: Low birthweight and multiple (twin and higher-order) birth rates for California were calculated for non-Hispanic mothers from birth certificate data for 2000. Births to the 1.9% of mothers identified as multiple-race were reassigned to single-race groups according to 12 "bridging" methods. Bridge methods utilized population-based whole allocation, fractional allocation, and other methods, primarily depending on first race listed. RESULTS: For large race groups, there was little difference in low birthweight and multiple birth rates regardless of the bridge method employed. For smaller groups such as Native Hawaiians and other Pacific Islanders and American Indians/Alaska Natives, there was substantial variation by bridge method in observed rates. CONCLUSIONS: Tracking trends in birth outcomes across the change in data collection will challenge public health researchers. This paper outlines advantages and disadvantages of various bridge methods.

Multiple-race mortality data for California, 2000-2001.

OBJECTIVES: To examine mortality rates and quality of race reporting for multiple-race individuals in California using the new multiple-race data available on the death certificate. METHODS: Death date were drawn from California vital statistics for 2000 and 2001. Denominator data were drawn from the 2000 census Modified Race Data Summary File. The authors calculated mortality rates and relative standard errors for multiple-race individuals as a whole and by county, and for the three largest reported multiple-race groups (African American and white, American Indian/Alaska Native and white, and Asian and white). RESULTS: Decedents reported to be of more than one race were disproportionately young, Hispanic, male, and never-married. Age-adjusted mortality rates for multiple-race groups were approximately one-sixth as high as rates for single-race individuals. There was substantial variability in rates for multiple-race decedents according to county of residence. CONCLUSIONS: Mortality rates for multiple-race people were implausibly low, and death certificates for multiple-race individuals were geographically clustered. Race reporting on death certificates will need to be improved before accurate death rates can be calculated for those of multiple races.
