Why Education is Essential for Health and Longevity

▴ Why Education is Essential for Health and Longevity
Every additional year of education can significantly reduce the risk of death, comparable to the benefits of healthy eating and the avoidance of smoking or heavy drinking.

Education is often regarded as a pathway to better job opportunities and higher earnings, but recent research highlights an even more critical benefit: increased life expectancy. According to a study published in The Lancet Public Health journal, every additional year spent in school or university can significantly improve life expectancy, while lack of education can be as harmful as smoking or heavy drinking.

A Global Perspective: This extensive study, conducted by researchers at the Norwegian University of Science and Technology (NTNU) and involving data from 59 countries, analyzed over 10,000 data points from more than 600 published articles. The findings are clear: education saves lives across all demographics, regardless of age, sex, location, or socio-economic background.

Quantifying the Benefits of Education: The research found that each additional year of education reduces the risk of death by 2 percent. For example, completing six years of primary school can lower the risk of death by 13 percent on average. Graduating from secondary school reduces the risk by nearly 25 percent, and attaining 18 years of education decreases the risk by 34 percent. These statistics illustrate that the health benefits of education are profound and measurable.

Education vs. Other Health Risk Factors: The study also compared the effects of education to other well-known health risk factors such as diet, smoking, and alcohol consumption. Remarkably, the benefits of education were found to be comparable to these factors. For instance, having 18 years of education is akin to consuming the ideal amount of vegetables versus not eating vegetables at all. On the flip side, not attending school at all is as detrimental to health as drinking five or more alcoholic drinks daily or smoking ten cigarettes a day for ten years.

Education Across Different Age Groups and Countries: While the benefits of education are most pronounced in younger individuals, older adults, including those over 50 and even 70, also experience significant health advantages from education. Importantly, the study found that the positive effects of education are consistent across countries, regardless of their stage of development. This means that more years of education are just as beneficial in wealthy nations as in poorer ones.

The Role of Social Investments in Education: Mirza Balaj, a co-lead author and postdoctoral fellow at NTNU, emphasizes the need for increased social investments to provide better and more education globally. Balaj notes that more education leads to better employment opportunities, higher income, improved access to healthcare, and better self-care. Educated individuals also tend to develop a broader set of social and psychological resources that contribute to their overall health and longevity.

Addressing Global Inequalities: Despite the compelling evidence, most of the studies reviewed were from high-income settings. This highlights a critical need for more research in low- and middle-income countries, especially in regions like sub-Saharan Africa and North Africa where data are limited. Claire Henson, co-lead author and researcher at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington's School of Medicine, advocates for closing the education gap to reduce mortality inequalities. She stresses that international commitment is essential to break the cycle of poverty and preventable deaths.

The Call to Action: Investing in education is not just a moral imperative; it is a strategic move to enhance public health globally. By promoting educational opportunities, we can create a healthier population, reduce healthcare costs, and improve overall quality of life. Governments, policymakers, and international organizations must prioritize education as a key component of public health strategy.

The link between education and life expectancy is clear and compelling. Every additional year of education can significantly reduce the risk of death, comparable to the benefits of healthy eating and the avoidance of smoking or heavy drinking. As a society, we must recognize the profound impact of education on health and take collective action to ensure that everyone has access to quality education. This will not only improve individual lives but also contribute to a healthier, more equitable world.

Key Takeaways

- Education Saves Lives: Each additional year of education reduces the risk of death by 2 percent.
- Health Benefits Comparable to Lifestyle Choices: The benefits of education are on par with healthy eating, and avoiding smoking and heavy drinking.
- Universal Impact: The positive effects of education are consistent across all age groups and countries, regardless of economic status.
- Call for Social Investment: Increased investment in education is crucial to reduce global health inequalities.
- Urgent Need for Research in Low-Income Regions: More studies are needed in low- and middle-income countries to understand and address educational disparities.

By integrating these insights into public health policies and strategies, we can make substantial progress towards a healthier, more educated global population.
