A Retrospective on Fundamental Cause Theory: State of the Literature and Goals for the Future

Fundamental cause theory (FCT) was originally proposed to explain how socioeconomic inequalities in health emerged and persisted over time. The concept was that higher socioeconomic status helped some people to avoid risks and adopt protective strategies using flexible resources: knowledge, money, power, prestige, and beneficial social connections. As a sociological theory, FCT addressed this issue by calling on social stratification, stigma, and racism as they affected medical treatments and health outcomes. The last comprehensive review was completed a decade ago. Since then, FCT has been tested, and new applications have extended central features. The current review consolidates key foci in the literature in order to guide future research in the field. Notable themes emerged around types of resources and their usage, approaches used to test the theory, and novel extensions. We conclude that after 25 years of use, there remain crucial questions to be addressed. Expected final online publication date for the Annual Review of Sociology, Volume 47 is July 2021.

Educational Attainment and Staphylococcus aureus Colonization in a Hispanic Border Community: Testing Fundamental Cause Theory

ABSTRACT This study was carried out to evaluate hypotheses generated by fundamental cause theory regarding the socioeconomic status (SES) gradient in colonization with Staphylococcus aureus among Hispanic and non-Hispanic adults living in a border community. Participants (n = 613) recruited in naturally occurring small groups at public and private sites throughout Yuma County, AZ, completed a sociodemographic survey and swabbed their palms, noses, and throats to sample microbial flora. Positive S. aureus colonization among non-Hispanic white participants was nominally higher (39.0%; 95% confidence interval [CI] = 32.4 to 46.1%) than that in Hispanics (31.3%; 95% CI = 26.4 to 36.8%), but there was no education gradient for the sample overall (incidence rate ratio = 1.00; 95% CI = 0.90 to 1.12) or within each ethnic group separately. The education gradient between Hispanic and non-Hispanic whites was statistically equivalent. Results were consistent when home ownership was used as the SES indicator. These data show that S. aureus colonization is not linked to two different SES indicators or Hispanic ethnicity. S. aureus colonization may be considered a less preventable health risk that is outside the influence of SES-based resources. IMPORTANCE Unlike some types of S. aureus infections, S. aureus colonization is not associated with ethnicity or educational attainment and thus may be outside the influence of socioeconomic status-based resources typically mobilized to avoid or mitigate preventable health risks. This assessment of a clinically silent risk that usually precedes infections may illustrate a boundary of fundamental cause theory.

Well-Being at the End of Life

This review proposes that the end of life is a uniquely contemporary life course stage. Epidemiologic, technological, and cultural shifts over the past two centuries have created a context in which dying has shifted from a sudden and unexpected event to a protracted, anticipated transition following an incurable chronic illness. The emergence of an end-of-life stage lasting for months or even years has heightened public interest in enhancing patient well-being, autonomy, and the receipt of medical care that accords with patient and family members’ wishes. We describe key components of end-of-life well-being and highlight socioeconomic and race disparities therein, drawing on fundamental cause theory. We describe two practices that are critical to end-of-life well-being (advance care planning and hospice) and identify limitations that may undermine their effectiveness. We conclude with recommendations for future sociological research that could inform practices to enhance patient and family well-being at the end of life.

Infusing fundamental cause theory with features of Pierre Bourdieu’s theory of symbolic power

The theory of fundamental causes is one of the more influential attempts to provide a theoretical infrastructure for the strong associations between indicators of socioeconomic status (education, income, occupation) and health. It maintains that people of higher socioeconomic status have greater access to flexible resources such as money, knowledge, prestige, power, and beneficial social connections that they can use to reduce their risks of morbidity and mortality and minimize the consequences of disease once it occurs. However, several key aspects of the theory remain underspecified, compromising its ability to provide truly compelling explanations for socioeconomic health inequalities. In particular, socioeconomic status is an assembly of indicators that do not necessarily cohere in a straightforward way, the flexible resources that disproportionately accrue to higher status people are not clearly defined, and the distinction between socioeconomic status and resources is ambiguous. I attempt to address these definitional issues by infusing fundamental cause theory with features of a well-known theory of socioeconomic stratification in the sociological literature—Pierre Bourdieu’s theory of symbolic power.
