Introduction Chronic diseases, which are also called non-communicable diseases are diseases that are not transmitted from one individual to another but instead develop gradually. Among the types of chronic diseases are cardiovascular diseases that are common not only in Western countries, but even in the Southeast Asian region where I reside. More specifically, I am now in the Philippines, and I have heard cases of cardiovascular problems increasing from the online news article. I was quite surprised that upon reading about health issues, I found out that cardiovascular diseases are the leading cause of death worldwide.
In connection to this, according to the World Health Organization (WHO), “raised BMI is an important cause of chronic disease” (Chronic Diseases and Health Promotion, WHO). Body Mass Index (BMI) is directly proportional to obesity. Therefore, I interpret this information as being overweight might also make the risk of developing chronic diseases, primarily cardiovascular diseases, greater, and thus mortality risk may also be higher. Knowing the information mentioned, I started to wonder about the prevalence of overweight in Southeast Asia. Consequently, I chose to investigate whether a correlation can be made between the prevalence of overweight among adult men and women and mortality rate specific to cardiovascular diseases in Southeast Asian countries. In order to come up with the analysis, I first listed the eleven Asian countries and their population size. I arranged them in order of the country with the highest to the lowest population.
After this, I collected data of the prevalence of overweight men and women in Southeast Asia for the year 2005 and 2015. Then, I collected the statistics of mortality rate by cause that was cardiovascular disease. After gathering these data, I organized them in one table in order to proceed with the correlation and analysis. In comparing, I used a bar graph to represent the prevalence of overweight versus mortality rate due to cardiovascular disease.Moreover, I illustrated the comparison of the prevalence of overweight versus cardiovascular disease by gender. Through making and analyzing a scatter plot, I will figure out if there is in fact a correlation between the prevalence of overage in Asian men and women and the deaths caused by cardiovascular diseases in their specific countries. Hypothesis: The higher the prevalence of overweight, the higher the mortality rate caused by cardiovascular diseases. Data Collection For the purpose of deriving a reliable data of Southeast Asia for this analysis, I selected the website of the World Health Organization and extracted the latest facts that focused on the Impact of Chronic Disease in every Southeast Asian country.
Before that, I listed down the population size of each country for 2005 and 2015. After which, I gathered the figures for the projected prevalence of overweight per gender for 2005 and 2015 in Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, East Timor, and Vietnam. Since I wanted to relate being overweight to the number of deaths in Southeast Asia, I also listed down the mortality rate by cause per 100,000 population is the said eleven countries. Table 1 shows the Southeast Asian countries in order of the greatest population size for 2005 and 2015, the projected prevalence of overweight among men and women in 2005 and 2015, and the latest data available for mortality rate by cause of cardiovascular disease per 100,000 population.ResultThe hypothesis that I formulated at the beginning of my research was, “the higher the prevalence of overweight, the higher the mortality rate caused by cardiovascular diseases.
” As a person who is living in Asia, I was curious how these two variables could be related. As a young adult, I have begun to be more health conscious and to stay fit. Thus, I wanted to analyze if there could be a correlation in between being overweight and dying due to chronic diseases, mainly cardiovascular disease. To be relatively specific, I focused on Southeast Asia, since I am in this area and now studying in the Philippines. In the analysis, I came up with bar graphs, scatter plots, and use the Correlation Coefficient that I learned in class for me to be able to correlate the prevalence of overweight and the mortality rate due to cardiovascular diseases among men and women in Southeast Asia. Through the scatter plots, it was evident that there was a very weak correlation of the two variables chosen among men due to the scattered points in the scatter plot.
However, for the Southeast Asian women, the observation was different because there was a strong positive correlation observed through the points being near each other.Furthermore, an analysis was done in order to determine the intensity of the correlation by computing for the correlation coefficient r. Through manual computation, the value of r for men was computed as , which suggests more strongly that there is weak negative linear correlation of the two variables among men. On the other hand, for women, the derived value was . Similar to the correlation analysis in words, there was a moderate positive linear correlation analyzed. Conclusion To sum up, this research suggests that using the mathematical processes believed as appropriate such as data analysis using the scatter plot and calculating the correlation coefficient, I have found out that the prevalence of overweight in Southeast Asian countries has a weak negative correlation to death caused by cardiovascular diseases in men.
However, for Southeast Asian women, the results of this work suggest that there is a moderate positive correlation between the prevalence of overweight and death caused by cardiovascular disease. My hypothesis that is, “the higher the prevalence of overweight, the higher the mortality rate caused by cardiovascular diseases” is therefore more appropriate for Southeast Asian women, but not for Southeast Asian men. Knowing this, I have realized that women should be more careful about their health. It is because the results of this work directly suggest the relationship of weight and cardiovascular disease. Although other factors may affect or contribute to having chronic illnesses such as stress and age, it is still better to avoid being overweight due to the risks of dying of cardiovascular disease.
