BONE MINERAL DENSITY TESTING IN SOCIAL CONTEXT

Abstract

Bone mineral density (BMD) testing of healthy women continues to increase, despite widespread discrediting of this test as a valid means to predict fracture risk. To find an explanation for this expanding utilization, we turn to the literature of sociology and political science. Two interdisciplinary approaches proved particularly useful in critical examination of technologies related to women and aging: feminist analysis and cross-cultural analysis. BMD testing has grown because it is marketed in ways that draw upon and perpetuate two trends in western popular culture: a) the medical model of the aging female body; and b) the fear of aging, with its associated disability, dependency, and immobility. The feedback loop between popular and scientific knowledge has created and perpetuated the notion that the aging female body is a diseased body. The trend toward defining osteoporosis entirely on the basis of BMD diagnostic criteria has resulted in the transformation of a risk factor into a disease entity. As the onus for managing risk falls increasingly on women as individuals, and as they strive to reach the preferred ideal of normality, the area that defines normality on the continuum is shrinking, while that defining abnormality is increasing. The power relations and private interests served by this altered continuum remain largely unexamined. The effect, however, is to encourage the demand for screening and diagnostic technologies, giving rise to the rapid diffusion of such technologies, even where the research evidence does not support their use.
