Introduction
The role of a
medical anthropologist is to understand health, illness, and healing in a range
of human societies to gain incite into an effective approach to improving
global health for all peoples. A global health issue encompasses health
problems that transcend national boundaries, and more often than not, the
prominent issues are ones that are publically recognized epidemics and
infectious diseases. Yet, global health encompasses more than just mortality
and biological abnormalities; global health also pertains to issues that
indirectly effect health and wellbeing. An anthropologist’s major role in
global health is to go deeper into the unknown aspects of health to unravel a
better strategy or a new approach to improving global health. Food insecurity
is not commonly referenced with global health, but extensive research is
uncovering comparable trends that point to a probable correlation between
global health and food insecurity. Food insecurity is the lack of “physical and
economic access to sufficient, safe, and nutritious food that meets dietary
needs and food preferences for an active and healthy life” (Hadley &
Crooks). The role of medical anthropologists in this study is to understand the
complex causes and consequences associated with the availability, access,
utilization, and stability of food. In the American
Journal of Physical Anthropology, Craig Hadley from the department of
anthropology at Emory University and Deborah Crooks from the department of
anthropology at the University of Kentucky collaborated to compile research on
food insecurity and its effects on global health. In Coping and the Biosocial Consequences of Food Insecurity in the 21st
Century, Hadley and Crooks investigate the mechanism of coping as the
mediator to linking food insecurity with health and wellbeing. This article
speculates the hypothesis that the change in behavior due to the decline in
access to food is related to global health problems, such as nutritional
status, chronic diseases, and mental health.
Historical
Context
In order to
tackle the potential relationships at play, the first task of a medical
anthropologist in global health intervention is to understand the development
of a problem by looking at its historical context. Anthropologists linked the
global food crisis with the global economic crisis and a number of other probable
causes that increased the fluctuation of food prices. In Global Health Watch 3, the report mentioned the impact of biofuels
in reducing the quantity of food production, and it also mentioned the neglect
of agriculture investment, which led to a decrease in cultivation, thus a
decrease in the availability of food. Although the population was rising,
anthropologist did not believe the supply and demand of food had changed, but
that food was being redirected and distributed unevenly. The report also
mentioned the unpredictable change in climate that was considered an additional
factor in changing the amount of harvest. Likewise, the article by Hadley and
Crooks similarly explored a number of plausible factors that contributed to the
global increase in hunger, such as demographic shifts, depreciation of economy,
uneven trade, etc. Hadley, Crooks, and anthropologists from Global Health Watch 3, contributed to
the list of factors that influenced food security but their views were
distinctively different. Anthropologists from Global Health Watch 3 separated the topic of the global food crisis
from health systems by distinguishing the food crisis in a separate section
titled “Beyond Health Care.” This indicates the distinction that the global
food crisis is a separate entity from health problems. But as new information
surfaced, Hadley and Crooks were able to contrast the former understanding of
food insecurity. The purpose of the article is to analyze current research to
evaluate whether the global food crisis is intertwined with global health
problem. Food security is a highly dynamic condition; therefore, coping is a
response to compensate the change in inaccessibility of food and resources.
This change in behavior mediates the probable relationships between food
insecurity and health.
Nutritional
Status
One health
problem that is speculated to relate to insufficient amounts of food is the
state of a person’s health in terms of nutrients in diet. The coping behavior
affiliated with the nutritional status of a household is the change in diet. Anthropologists
believe that the burden of food insecurity would cause households to consume an
insufficient amount of food and have “undernutrition,” a term used in the
article to describe an inadequate level of nutrition compared to the norm. This
hypothesis was applied to various societies to determine the validity of the
claim. Many of the studies showed that low income countries confirmed the
relationship between underweight and food insecurity. An example that supports
the hypothesis is presented in the Argentina study. “In food secure households,
~19% of children were stunted, compared with 25% in moderately insecure
households and 33% in households with hunger” (Hadley & Crooks). As food
insecurity increased, the percentage of children stunted also increased; the
number of children found underweight due to insufficient amounts of food is
apparent in the data. Although all the reported studies did not present the same
confirming results, error was taken into account, and the overarching
conclusion was that there was enough positive backing to support the claim that
a relationship between undernutrion and food insecurity existed among low-income
households. In contrast, a reverse hypothesis was also formulated. Anthropologists
considered that a relationship between food insecurity and overweight/obesity
could exist because food insecure households could compromise healthy more
expensive choices for cheaper unhealthy choices. However, the overweight and
obese research contained mostly inconsistent results and presented only a few
cases in which middle to high-income households presented overnutrition due to
food insecurity. The trend showed that higher income countries showed more
variability in data, therefore, invalidating the predicted relationship between
food insecurity and overweight/obese individuals. These results were predicted
to be due to the fact that low-income households altered their quantity to cut
costs, while middle to high income households altered their quality of food to
consume cheaper, energy dense foods. It is significant to acknowledge the trend
and relationship that the compilation of this article presents because the
impact that food insecurity makes on the nutritional status of individuals
represents the high probability that severe cases would hinder growth and
development and result in malnutrition. And if food insecurity and obesity develop
a stronger correlation, the nutritional statuses of obese individuals result in
various risks like diabetes and cancers, such as the heart and liver. Because
anthropologists found a possibility that food insecurity could lead to
detrimental health effects and possibly chronic diseases, research was extended
further into the possible relationship between food insecurity and chronic
diseases.
Chronic Diseases
The article also
dissects diabetes and HIV to discover if a significant correlation exists
between chronic diseases and food insecurity. The coping behavior related to
chronic diseases and food insecurity is compromising treatment of illnesses.
Individuals are unable to improve their health because of food insecurity
restraints. The results from multiple studies showed that “when more severe
measures of food insecurity were used, the relationship between household food
insecurity and diabetes became statistically significant” (Hadley &
Crooks). This showed that more diabetics were found to be food insecure; this
relationship complicated the treatment of the disease because food insecure
diabetics would have difficulty adhering to the necessary food requirements to
maintain blood sugar levels. Because food insecurity is often driven by
poverty, low-income socioeconomic status, financial burden is also a
significant factor in revealing a relationship between food insecurity and
illnesses. The financial stress is mentioned in WHO’s World Health Statistics Report 2012. “Based on data covering 90% of
the world’s population, an estimated 100 million people are pushed under the
poverty line each year simply because they use health services for which they
are forced to pay out of their own pockets.” This shows that some individuals would
have to choose food above medical treatment because financial resources limit
the possibility of attaining both. There is an apparent relationship among
diabetes and food insecurity; therefore, this raises the question of whether
diabetics become food insecure due to burdensome medical expenses, or food
insecure individuals develop diabetes because of poor food accessibility. Both
speculations lead to the same result, the health of diabetics who are food
insecure does not improve. The same correlation was found in the HIV study. The
issue of high medical costs also pertains to the HIV study. The medical
expenses used for treatment of HIV could theoretically be used to attain food
security. Since one had to be compromised, there was a significant relationship
between HIV individuals who were found to also be food insecure. In sub-Saharan
Africa, individuals would decline the antiretroviral therapy (ART), which would
suppress the virus and reduce the progression of HIV, because of the burden of
food insecurity. “A surprising obstacle to ART initiation for 76% of patients was
fear of developing too much appetite on ART but not having enough to eat”
(Hadley & Crooks). This lack of resources hindered the treatment of a
chronic disease. This case shows that food insecurity was the determining
factor for refusing to improve a life threatening disease. “Food insecure
participants of ART were 50% more likely to die compared to food secure”
(Hadley & Crooks). This data shows that the condition of food insecurity
was as important, if not more, than the treatment of HIV. This research is
significant because food insecurity is under the radar compared to the urgency
of treating HIV, efforts to improve the food crisis is somewhat neglected. But
as the study shows, without also addressing the food insecurity problem, other
chronic diseases cannot be effectively treated. Therefore, the priority of
global health interventions needs to be reevaluated to incorporate the equal
dispersion of food. As a result, this would improve the treatment of other
global health problems.
Mental
Health
The last health
problem analyzed in relation to food insecurity was mental illnesses. Because
food has an important biological and social value, the lack of sufficient food
would cause stress, and stress was speculated to cause the onset of mood
disorders, such depression and anxiety (Hadley and Crooks). The research
conducted presented confirming results in all cases that food insecurity
associated with nearly three times greater odds of symptoms of anxiety and
depression. Mental health disorders were associated with food insecurity in adults
and behavioral disorders were associated with food insecure in children. In Global Health Watch 3, the section
entitled “mental health” mentioned the same complimentary results like the
article. “Financial insecurity, related to lower income, can promote feelings
of hopelessness and shame, which increases stress. In Tanzania, a study found
that food insecurity and changes in food insecurity across seasons were strong
predictors of symptoms of anxiety and depression. In Ethiopia, it was found
that stressful life events in addition to food insecurity increased
susceptibility to mental disorders” (Global Health Watch 3). This information
also supports the relationship between the lack of food and mental health.
Another speculation in the research of mental health deals with the same
concerns referenced in the chronic diseases study. Which direction is the
reaction occurring? An individual may develop food insecurity because his
mental illness limits his capacity to sustain security, or food insecurity may
onset feelings of anxiety and depression and cause the individual to become
mentally ill. The complexities surrounding this subject have to do with
interpreting whether food insecurity seems to cause adverse health or whether
adverse health causes individuals to become inadequate in attaining sufficient
amounts of food. Although the answer is unclear the same conclusion is still
reached; the global food crisis must be addressed as a priority.
Research
The
research presented in the article ranged from different models and various
questionnaires that sometimes varied the reliability of comparing multiple
cases. The difficulties accompanying the study dealt with the specifics of defining
and measuring the variable “security.” The error in the inconsistency of data
was postulated to be the result of the variation by culture and society or caused
by the method used to extract information from a sample of people. There is no
clear objective tool to measure the food insecurity. In terms of chronic
illnesses like diabetes, the researchers who conducted the study stated that
individuals would self diagnose or under diagnose and skew the results.
Therefore, anthropologists played a crucial role in constructing, validating,
and adapting scales to maximize the accuracy of data (Hadley & Crooks).
Nevertheless, the shift in “medicalizing” food insecurity is accompanied by
error. This is similar to the concepts discussed in class involving the
medicalization of conditions like ADHD, anorexia, and evil eye. Opposition in globally
recognizing a state or condition is difficult because cultures disagree with
the legitimacy and diagnosis of conditions. There is a lot of room for
variation and error. However, if a problem such as food insecurity is widespread,
the persistence of the condition, along with the possible correlations involved
with it, indicates its significance.
Conclusion
Food
insecurity has been a global concern and a serious issue, yet its adverse
effects have only recently been speculated to concern health. Its relationships
are still a very new concept. After seeing the anthropological perspective on
food insecurity, questions concerning “why” are addressed. It sheds light into
the understanding of why individuals would refuse treatment of life threatening
diseases, or why a large population of diabetics is found to also be food
insecure. Conceptually, the anthropological perspective is a view that is
uncommon, but foresees new solutions. However, the plethora of research
accumulated in this article did not completely confirm speculated associations
between food insecurity and global health problems; conclusions were unclear. “While
anthropologists are trained to find patterns, we are also trained to recognize
the disjunctures and contradictions that are part and parcel of everyday
experience” (Hadley & Crooks). It may seem frustrating that opposition in
every speculated relationship concludes in ambiguity and no closure, but the
ultimate goal of an anthropologist is not to find a solution, but the emphasis
is on understanding the problem in order to find a solution. The practical
perspective determined from the anthropological perspective would be to
prioritize food insecurity in global health efforts. The speculated relationships
clearly showed that food insecurity encompasses aspects of health that are
critical and cannot be effectively treated if food insecurity is neglected.
