Collecting epidemiologic data by ethnicity and race is a highly useful
undertaking; but ''bench-mark'' comparisons relative to majority Amer
icans should not take priority over defining the determinants of healt
h status within a minority group. Thus, it is necessary to identify fa
ctors contributing to the measured health status and to modify the env
ironment, lifestyles, and behaviors to diminish the likelihood of unde
sirable health outcomes. This article presents an overview of the heal
th status of African Americans, Asians and Pacific Islanders, and Hisp
anics. The goals are to provide a framework for the rational interpret
ation of both health status data and its determinants both within and
between minority groups. This approach recognizes the heterogeneity of
health status that exists within a minority group and encourages inve
stigators to place more emphasis on the within-group health status dif
ferentials as they search for modifiable factors that underlie the ris
k for undesirable health outcomes.
