Ischemic heart disease mortality in Hispanics, American Indians, and non-Hispanic whites in New Mexico, 1958-1982.

Abstract

To describe trends in mortality from ischemic heart disease in New Mexico's Hispanic, American Indian, and non-Hispanic white populations, we used vital records data collected from 1958 through 1982. We calculated age-adjusted and age-specific mortality rates for ischemic heart disease for each of the state's principal ethnic groups. Death certificate data were used in combination with population estimates based on the censuses of 1960, 1970, and 1980. Age-adjusted mortality rates for ischemic heart disease among Hispanics, American Indians, and non-Hispanic white men were consistent with nationwide patterns of rising mortality rates during the 1960s followed by declining rates. Mortality rates from ischemic heart disease in all three ethnic groups in New Mexico were lower than national rates for whites. Rates for Hispanics in New Mexico were lower than for non-Hispanic whites; rates for American Indians were the lowest among the three groups. These data support previous observations that Hispanics and American Indians in the Southwest are at decreased risk for mortality from ischemic heart disease in comparison with U.S. whites.
