Racial and ethnic differences in premature heart disease deaths in New Mexico: what is the role of diabetes?

Multiple-cause mortality files from 1999-2001 were obtained to describe premature heart disease (PHD) deaths and the role of diabetes as a contributing cause in heart disease (HD) mortality in American Indians, Hispanics, and non-Hispanic Whites in New Mexico. The proportion and rate of PHD and diabetes-related HD death were calculated and reported by race/ethnicity and gender. Results indicate that from 1999 to 2001, 24% of all deaths in New Mexico reported HD as the leading cause of death. Of these, 16.6% occurred in persons <65 years of age and were therefore classified as premature. The proportion of premature HD deaths was substantially higher in the American-Indian (29.2%) and Hispanic (20.8%) populations compared to Whites (13.7%). Furthermore, diabetes contributed to almost 18% of premature HD deaths in American Indians and Hispanics and to 10% of premature HD among Whites. These findings suggest that American Indians and Hispanics are disproportionately affected by premature HD death and that diabetes as a contributing cause is greater among these populations compared to non-Hispanic Whites.
