This paper argues that analysis of the ethnic patterning of health has
failed adequately to examine the social meaning of ethnicity, while t
oo often becoming enmeshed in unhelpful dualities which counterpose ma
terial to cultural explanations, multiculturalism to anti-racism, and
sociology to epidemiology. Against the background of anthropological,
objectivist and postmodern theories in the broader sociology of 'race'
and ethnicity, the paper develops a concept of ethnicity for the purp
oses of health research. This is used to evaluate biological, migratio
n-based, material, cultural and racism-based explanations for the ethn
ic patterning of health. It is argued that these types of explanation
are best understood within an interactive framework. The methodologica
l implications of this for future research are discussed.
