Research consistently indicates that wealth and healthy life expectancy (the period of life spent in good health) are inextricably linked. Numerous studies, both domestic and international, arrive at the same conclusion: the wealthy tend to live healthier for longer. This is often attributed to better nutrition, regular health screenings, and proactive physical maintenance. Some findings even suggest that high-income women are more diligent about weight management. Let’s examine the specific relationship between economic power and health.
72.7 vs. 64.3 Years: The Income-Based Health Gap
New data reveals a significant disparity in healthy life expectancy based on income levels in South Korea. In 2022, the healthy life expectancy for the top 20% of income earners was 72.7 years. In contrast, the bottom 20% averaged only 64.3 years—a gap of 8.4 years. This divide has widened steadily from 6.7 years in 2012. These figures were analyzed by the Ministry of Health and Welfare and other agencies using data from the National Health Insurance Service (NHIS) and the Korea Disease Control and Prevention Agency (KDCA), as reported in the "Healthy Life Expectancy Statistics" released on the 8th. The overall healthy life expectancy for South Koreans currently stands at 69.9 years.
Mortality Risk: Why the Poor Face 2.3 Times the Risk
The health advantages enjoyed by the wealthy are a well-documented phenomenon. A 2012 paper published in the Asia-Pacific Journal of Public Health noted that economically well-off South Koreans enjoy a significantly better healthy life expectancy than those in poverty. The mortality risk for individuals in the lowest 10th percentile of economic status was 2.3 times higher than those in the top 10th percentile. Wealthier individuals generally possess higher health literacy and often live in closer proximity to major medical centers, providing a distinct advantage in managing their wellbeing.
The 10-Year "Health Loss" Period
According to the National Data Center (2024), the average life expectancy in South Korea is 80.8 years for men and 86.6 years for women. However, the overall healthy life expectancy remains much lower at 69.9 years. Healthy life expectancy is calculated by subtracting the "period of health loss" (years spent with illness or disability) from the total life expectancy.
By gender, men (67.9 years) have a healthy life expectancy about four years lower than women (71.7 years). The rising prevalence of chronic conditions like hypertension (high blood pressure) and diabetes is a primary reason for this shortened period of health. Chronic diseases currently account for 78.8% of deaths in South Korea.
The Importance of Prevention: Managing the "Silent Killers"
Preventing chronic diseases such as hypertension, diabetes, and dyslipidemia (hyperlipidemia) is the most effective way to extend healthy life expectancy. These conditions are major risk factors for the leading causes of death, including heart disease, stroke (cerebral infarction and cerebral hemorrhage), and kidney disease.
Early detection and prompt treatment are essential. Rising obesity rates are also contributing to the decline in healthy years. Wealthy individuals are statistically more likely to avoid alcohol and smoking, exercise regularly, and stay informed about health trends. In contrast, those struggling with daily living expenses may turn to alcohol or cigarettes as a coping mechanism. Ultimately, a loss of healthy life expectancy is not just a personal struggle; it places a heavy financial and emotional burden on spouses and children.
