Coronary heart disease mortality for six ethnic groups in California, 1990-2000.Ann Epidemiol 2004; 14(7):499-506AE
To investigate ethnic variations in coronary heart disease death in California, the authors examined total and CHD-specific mortality among non-Hispanic white (white), Hispanic, non-Hispanic black (black), Chinese, Japanese, and Asian Indian Americans. Deaths were identified in the California Mortality Database and population information was derived from the 1990 and 2000 censuses.
Age-standardized death rates per 100,000 population were calculated for ages 25 to 84 years from 1990 to 2000. Proportional mortality ratios (PMRs) for each sex and age group were calculated by dividing the proportion of deaths due to CHD in each ethnic group by the proportion of deaths due to CHD in the total population.
Blacks had the highest all-cause age-standardized death rates among men (1614) and women (1014). Blacks had the highest CHD death rates among men (272) and women (190). PMRs for CHD were highest in Asian Indian men (161) and women (144), reflective of the higher percentage of CHD deaths compared with all cause deaths in this group. All sex-ethnic groups showed a decline in all cause and CHD mortality compared with the period between 1985 and 1990, except Asian Indian women, who experienced a 16% increase in all cause mortality and 5% increase in CHD mortality.
There is considerable heterogeneity in CHD mortality among ethnic subgroups, and additional research is needed to guide treatment and prevention efforts. Blacks and Asian Indians in California are identified as particularly high risk populations.
