(Alcohol Metabolism: An Update) Because of the consequent health problems that result from
prolonged alcohol consumption and the accessibility of alcohol, alcohol use disorders are a threat
to the health of the global population. According to the WHO, 5.3% of deaths worldwide result
from the use of alcohol and is the cause of 13.5% of deaths in the 20 – 39 year age group.
AUD is a significant problem worldwide, specifically in South Korean society. South
Korea has the highest rate of alcohol consumption in the world and alcohol abuse is quite
prevalent in modern day Korean society. Personally, I have seen friends become active alcohol
consumers when they enter college and I also come from a very “alcohol loving” family. Both of
, 3
my grandfathers died of liver cancer and I know that Korea has one of the highest rates of liver
cancer in the world. I think that this topic, alcoholism in South Korea, is a significant topic of
research because rising levels of alcohol consumption in any country are a threat.
Figure 1 Ferdman, Quartz
According to data analyzed by Euromonitor in 2014, South Koreans drink, on average,
13.7 shots of liquor per week which is about three times as much as the Japanese, with 4.4 shots
per week, and about nine times more than the Chinese, with 1.5 shots per week. South Korea,
which has the legal drinking age of 19, also came in 6th in the number of liver cancer incidents in
, 4
the data analysis done by the World Cancer Research Fund International in 2012. In the same
data analysis, China came in 7th and Japan did not even rank in the top 20.
The purpose of this analysis is to explain high rates of alcohol consumption in the South
Korean population by looking into ethnically specific genetic characteristics of the population
and societal acceptance and encouragement of alcohol consumption, specific to South Korean
culture. This will be done by exploring the research question, “To what extent do genetics related
to alcohol digestion and sociocultural factors such as the popular drinking culture, affect alcohol
consumption in the South Korean population?”
In comparison to neighboring East Asian countries such as China and Japan, South Korea
has significantly higher statistics of alcohol consumption despite the fact that the three countries
share similar genetic characteristics. Thus, there must be a sociocultural factor that encourages
alcohol consumption that counter acts the alcohol rejection mechanism provided by the
population’s genetic ethnic characteristics. Ethnic genetic traits specific to Koreans, inhibit the
chances of an individual of the Korean ethnicity consuming heavy amounts of alcohol in
comparison to other ethnic groups, such as Caucasians. However social influences within the
South Korean society amplifies the chances of high alcohol consumption. Thus, the genetic
factors of the population influence the population’s inclination towards alcohol consumption to a
smaller degree than the sociocultural factors.
In this essay, I will be discussing genetic factors that affect alcohol consumption in the
South Korean population by analyzing relevant research and giving basic background
information, such as the importance of genetics in alcohol digestion and ethnic specific genetic
, 5
traits that prevent or act against the chances of alcoholism. I will discuss the social aspect of
alcoholism in South Korea by looking into different parts of the culture where heavy drinking is
encouraged. Some examples are the “hweshik” culture in corporate settings, or drinking parties,
and the drinking culture amongst Korean college students, and the shifting cultural dimensions of
the Korean society.
The aim of this essay is to evaluate two contrasting factors influencing a specific
population’s inclination towards alcohol consumption by an extensive literature review to give
an insight into what may cause a population-wide health problem, such as alcoholism.
Furthermore, the essay attempts to suggest a broader scope of where the solution of this global
health problem may lie. By doing so, it aims to establish that addictive disorders, such as
alcoholism, are indeed a societal and a global phenomenon that require global awareness.
