1. A growing body of literature documents the relevance of all the social determinants—both structural stratifiers and intermediary determinants—identified in the WHO CSDH Framework to rural health inequities. That said, arguably the most thoroughly researched SDH in the field of rural health is the intermediary determinant of the health system as a social determinant. This area of research looks at health systems factors such as availability and access, both in geographic and economic terms, for example, such as hospital or provider population density and insurance coverage. The intermediary determinant of behavioral and/or biological factors has also been well-studied in rural health, documenting the various ways that rural residents engage in more health risk behaviors and fewer health-promoting behaviors. Given the predominance of these research approaches, I would argue that it is now most relevant for the field of rural health to look more closely at the structural stratifiers of income, education, and occupation, and the intermediary determinants of material and psychosocial factors. I believe these are especially important to look at precisely because of their lifecourse and intergenerational impacts. The structural determinant of race/ethnicity in rural health has also been less studied, but what research does exist indicates that this SDH functions differently across rural/urban populations, pointing to the importance of addressing this aspect in future research. This area of inquiry is of increasing importance given the demographic shifts that are happening in rural areas across the U.S. The most illuminating recent developments in rural health inequities research have come from the exploration of the ways that the social determinants operate differently between rural and urban areas and the exploration of rural status as a social determinant in itself.
2. The field of rural health and rural health inequities research is very broad and diverse, and the application of a socioecological or social determinants framework is similarly so. These frameworks have been incorporated across different scales, for example by the CDC, HRSA, and Healthy People 2020 in their respective work on rural health, as well as by policy and research institutes, and collaborative and individual academic research initiatives. This breadth of application reflects a well-developed theorization of the social determinants in rural health. Although there are many examples of rural health disparities research that effectively incorporates the social determinants into rigorous empirical design, the overall impact of the field could be strengthened by a more comprehensive and coherent application of a social determinants framework.
