Income Inequality Kills Adult Health by Anh Nguyen



            In a TED Talk, Richard Wilkinson states, “People in richer areas live anywhere from 5 to 12 or even 14 years longer than people in poor areas”. As we can see from this quote, income inequality kills. It kills the innocent lives of those who are unfortunate enough to live in these poor areas and lose 5 to 14 years of their life. To me, this is unfair, and undoubtedly this is unfair to everyone. Life is priceless. Inequality is killing the adults that live in these areas, and we cannot let this continue on any longer. By highlighting the income inequality between the low income and high income class, it will bring to light how income inequality affects cardiovascular health, leading to death. In this article, I will analyze Martinson’s works and findings on income inequality in health at all ages, but focusing on males age 35+ as the baseline for this article as adult age. I will also analyze Wilkinson’s works and findings on income inequality and mortality rates, this time using age 25+ as the baseline.
            To begin with, I will highlight the income inequality that exists between the lower and the upper class families as found in Martinson’s study. For the 20th percentile, the US household income was $20,262; whereas the 95th percentile was $186,000. The difference between this is an astonishing $165,738. By highlighting this important statistic, I will be able to explain to you why income inequality is such an important factor in adult health. With more resources, one is able to get more from their resources; whereas someone with little can only get little. With $20,262, one can only get that much in resources; the person with $165,738 can get that much in resources, the difference is amazing. With the baseline for income inequality established for the 20th and 95th percentile – the low and high income class – we will now discuss the prevalence of cardiovascular problems in each group.
            Looking again at Martinson’s findings, the prevalence rate of diabetes in the age groups of 35-49, 50-64, and 65-80 is greater in the low income than the high income class. Comparing the 35-49 groups, the lower income class had a 7.7% prevalence rate whereas the high income had a 3.5% prevalence rate. The 50-64 age groups were 17% and 8.3% prevalence rate. And the 65-80 age groups were 19.6% and 10.2% prevalence rate. As we can see from this data, the low income group had a higher prevalence rate for diabetes as compared to the high income group. Interpreting this data introduces multiple risk factors that induce the different groups to produce this behavior. With the low income group, they had less money and therefore had fewer resources to prevent diabetes. With low income families, they are more likely to partake in behavior that may not be very healthy for themselves, because they are unable to get the resources to maintain a healthy diet due to money restrictions. As said by Martinson, “Smoking was most prevalent among low-income individuals and least prevalent among high-income people”. The use of tobacco for an individual can increase their blood sugar levels and that will lead to insulin resistance. Therefore, the more one smokes, the more they risk themselves to developing diabetes. This quote shows the statistic that low-income individuals will partake in behaviors that are detrimental to their health. Martinson also highlights the insurance rate of those in the United States, being one-third of low-income individuals are uninsured and only 6% of high-income was uninsured. By having insurance, an individual will be able to treat their illnesses early on, and this applies to diabetes as well. With enough money, people will be able to take care of themselves and afford the care that they need in order to prevent the onset of diabetes.
            There are also other statistics that stand out in Martinson’s research, which include heart attack rates and stroke rates. Looking at the age groups of 50-64 and 65-80 for heart attack rates, we can see that the first age group has a 13% rate for low-income and a 5.8% rate for high-income. For the 65-80 age groups, there is a 26.8% for the low-income and a 16.1% for high-income individuals. The explanation for this is found in Martinson’s research, where he explains that early detection systems and pre-screenings for heart problems exist to those of the high-income class; more so for those who can afford the care. The stroke rate for the age groups of 65-80 is 10.6% for low-income and 6.1% for high-income. Although the difference in the stroke rate is not drastic, the difference still remains that we can see a gap that exists between the low-income and high-income group in terms of their health. The underlying reason and main factor behind this is better healthcare and treatment by those who have the money to get the best treatment around. Although it is hard to understand, high-income individuals have it made, in that they will live longer than those in the low-income group because they receive the best care for the money that they put in. These statistics of diabetes, heart attack and stroke prevalence rate highlight the disparity that exists between low and high-income groups. What comes last in life is death, and by understanding that health problems are more prevalent in low-income groups than high-income groups is because of income inequality, it will be easier to understand why death comes easier to the low-income group.
            Transitioning over to Wilkinson’s work on Income Inequality and Socioeconomic Gradients in Mortality, we will come to understand the statistics of death due to the categories of All Causes, Ischemic Heart Disease, and Respiratory Disease. For the mortality rate on All Causes, the age group defined here is the working age – 25 to 64 years old. For this test, Wilkinson used a multilevel analysis of state-level income and income inequality versus mortality rate to find the interaction value between the two. This produced a significant value that would be compared to a P value and would either reject or fail to reject the original hypothesis. The original hypothesis would be that there is no interaction between the two, whereas the alternative hypothesis finds that there is an interaction between the two. For all three categories of All Causes, Ischemic Heart Disease, and Respiratory Disease, the significant value would reject the hypothesis for all three and would therefore find that there is an interaction between income inequality and mortality rates. The explanation behind this would be explained by Martinson’s findings, that low-income groups partake in behavior that is detrimental to their health, such as smoking – which leads to respiratory disease. And the failure to screen for heart disease due to income inequality to prevent the onset of any heart problems would explain the onset of ischemic heart disease. Again, we can see here that money provides for the best care and screening that one needs in order to detect diseases and illnesses before it is too late. From all of this, we can link Wilkinson’s findings to show that income inequality does indeed lead to death. With his findings on the interaction level between income inequality and mortality rates, we are able to highlight that low-income families are at a higher risk to die than high-income families. This is because the low-income families are not able to afford the care that they need whereas the high-income families can. Money is what widens the gap between the two in terms of their health.
            In conclusion, we were able to establish the income levels for each group and therefore continue on with our discussion. We can draw from Martinson’s findings the rate at which different age groups and income levels have diabetes, and how the different income level’s behaviors affect this. By partaking in high-risk behaviors such as smoking, low-income individuals put themselves in a position where they will develop heart disease. Wilkinson’s findings then related all of the information into an analysis of how income inequality does in fact lead to death. We are then able to confirm that income inequality between the low and high-income groups leads to the death of the low-income group. This disparity will continue to exist, and many more will continue to die. To put this into perspective, the difference is 5-14 years. To anyone humane, the amount of years lost should not justify the income inequality that exists today.
