title: Dimensions of health and social structure in the early intermediate period cemetery at Villa El Salvador, Peru.
abstract: This paper examines relationships between the social structure of a community and the health of its members, based on analysis of human skeletal remains (N = 64) from Villa El Salvador XII (100 BC-AD 100), a prehistoric cemetery located in the lower Lurín Valley, Peru. The ambiguity of social status as conventionally inferred from archaeological context is among the principal complicating factors in such an inquiry. We use multidimensional scaling of skeletal markers to identify the presence of patterned health-based heterogeneity in our sample, without making a priori assumptions about underlying social structure at Villa El Salvador. This procedure situates every skeleton relative to all others in the sample on the basis of multiple health markers, eliciting health groups. Once recognized, the relevance of those groups to social structure can be evaluated by comparison with a broad range of presumptive archaeological status indicators. We test the hypothesis that the distribution of stress indicators in human skeletons covaries with archaeological indicators of social differentiation. Based on multivariate analysis of skeletal indicators, we conclude that the cemetery at Villa El Salvador was utilized by two social groups with different geographic affinities: one of local coastal origin, and the other probably from the upper Lurín Valley or adjacent higher altitudes. These groups differ in skeletal characteristics related to childhood health, probably reflecting systematic contrasts in the growth environments of the studied individuals. This same division is independently supported by the distribution of cranial deformation, a possible marker of ethnicity. We also document some inequality in the distribution of labor among male individuals, as reflected by the relative advancement of degenerative joint disease, and congruent with differences in the number and quality of associated funerary offerings.
