Health geography

Health geography studies the spatial aspects of public health, such as the geographic distribution of disease and the conditions that lead to disease spread or epidemics. As a science, geography is concerned with distribution, landscape and space, and the interactions between the social and natural environments. This includes how people live in the spaces they inhabit, at various scales. Health geography as a formal discipline began to coalesce in the 1970s. From the beginning, it offered a holistic perspective, integrating geography and health sciences with other fields, such as sociology and biology. It is known variously under other names, such as geography of human well-being, geography of pathology, geomedicine, and others.

As a subfield of human geography, health geography is also often considered to fall in the loosely defined realm of social geography. Some critics, however, question the existence of an independent field of health geography, arguing that it is not really distinct from epidemiology, the branch of medicine that deals with disease distribution.

Overview

The relationship between geography and health has been documented since ancient times. In order to survive, early societies were concerned with developing mechanisms to identify what is healthful and what is harmful in the world around them. However, it was not until the late twentieth century that health geography formally organized as a multidisciplinary field. By that time, scholars sought to answer questions related to people’s well-being and the connections between disease prevalence, social and spatial distribution, and other spatial factors connected to public health.

In the context of health geography, then, geography transcends the study of landscapes and regions, and health science moves beyond examining microbes, vectors of disease, contaminants, and transmission. Health geographers also incorporate the social science, with the understanding that space and human groups are historically constituted; that is, health, disease, and quality of life are the consequences not only of biological and climate imperatives, but also of socioeconomic structures that develop in a specific cultural and physical area. The questions of where and how people live are inextricably tied to social conditions.

By mapping the geographic distribution—or the distribution within a space—of specific health variables, experts can interpret relationships within a dataset. For example, spatial analysis might reveal a direct cause-and-effect relation between variables contributing to a disease outbreak, as in a famous case in nineteenth-century London in which mapping instances of cholera helped trace the cause of the outbreak to a single contaminated well. Such analysis can help determine if the key factors behind public health issues are natural, social, or a combination of both.

Take, for instance, the relationship between smoking and lung cancer, or between socioeconomic status and the incidence of diabetes and hypertension. Data clearly indicates that there is a higher incidence of such health problems in some populations as opposed to others; health geography seeks to understand the often complex reasons behind such distributions. In these cases and many others, many geographers suggest that the answer points to issues of social inequality, including access to health services, education, sanitation, proper nutrition, and safe working conditions. Studies have consistently shown that people are distributed in a framework of geographic spaces of inequality, and this correlates closely with the prevalence of disease.

Health geography is deeply concerned with epidemics and pandemics, which are inherently geographic issues and lend themselves to complex, multidisciplinary analysis. Infectious diseases such as Ebola, for instance, are conditioned by local characteristics such as climate and fauna. However, cultural, social, and economic conditions determine how the population comes into contact with infectious disease pathogens, as well as with the resources available to control the spread of disease. Health geographers study these conditions and work to develop systems to help prevent large-scale outbreaks.
