Previously, I discussed changes to our model of health due to randomized control trials and the pharmaceutical industry, as discussed in Joseph Dumit’s Drugs for Life. Here are the three primary models of health as discussed by Donald A. Barr in his book Health Disparities in the United States: Social Class, Race, Ethnicity, & Health.
The first model is the medical model or physical health model that focuses on the absence of symptoms or other signs of disease or illness. However, Barr mentions several issues with this model of health, noting “that this approach to defining health tells us what the concept of health is not. . .It does not tell us what health is” (2014, pp. 15). He expands on this later:
“What are we to make of a condition that has no abnormal symptoms? An important example of this is high blood pressure, also referred to as hypertension; persons with hypertension develop symptoms only after a number of years. Should we consider a person with somewhat elevated blood pressure to be unhealthy based on our knowledge that his blood pressure will eventually lead to further problems? What might be the consequences of labeling such a person as ‘unhealthy,’ even if he feels fine?” (Barr, 2014, p. 16)
These are the questions that Joe Dumit attempts to answer, looking beyond hypertension to guidelines about pre-hypertension and the prescriptions of statins with no understanding of when patients can stop taking them.
The second model is the sociocultural model or the model of health as functioning at a normal level. Barr looks at it in contrast to the medical model, which looks at absence, because the sociocultural model looks at the presence of an ability to function at a level that has been deemed normal (2014, p. 17). The ability to functional normally is defined in regards to one’s ability to completed five “activities of daily living (ADLs),” which are roughly, (1) eating, (2) bathing, (3) dressing, (4) using the bathroom, and (5) moving on one’s own (2014, p. 17). Of course, the entire premise of “normal functioning” is subjectively predicated on societal ideas of self-sufficiency that might vary from culture to culture or community to community.
The third model is the psychological model or the model of health as a feeling of well-being. In this model, individuals are able to assess themselves and their own health with the help of several developed measures (Barr, 2014, p. 18). However, Barr notes that these tests are often “time-specific” (Barr, 2014, p. 18). I would argue that health is always time specific and temporal. I may be healthy today, but I can quickly develop a health problem or injure myself, perhaps even resulting in a temporary or life-long disability, reaffirming the temporality of both health and disability.
According to Barr, these models can be combined to create a multidimensional model of health that presents a better picture of the health of an individual.
