Extending the number of years spent in school not only provides individuals with a better education but also has been linked to living longer and experiencing less cell damage, according to a recent study analyzing data from 3,101 individuals spanning three generations. While the general consensus is that increased education leads to an extended lifespan, the exact reasons behind this correlation are still being investigated. Researchers from the US, Norway, and the UK set out to delve deeper into the connection between education and health, focusing on the impact at a cellular level.
The study, using data gathered from the Framingham Heart Study – a research venture tracking a large population in Framingham since 1948 – revealed that an additional two years of schooling corresponded to a 2-3 percent decrease in the rate of aging. By utilizing an epigenetic clock algorithm to measure biological age through DNA markers, the researchers were able to identify a relationship between education and the aging process unlike any previous studies. This analysis marks the first attempt at linking educational attainment directly to biological aging markers in the human body, offering new insights into the potential benefits of furthering one’s education.
To account for confounding variables such as familial educational background and available resources, the researchers investigated the concept of ‘educational mobility’ – the extent to which an individual’s education surpasses that of their parents and siblings. The results indicated that upward educational mobility was associated with both a decelerated pace of aging and a reduced risk of mortality. This finding suggests that the benefits of education go beyond socioeconomic status and extend to physical health and longevity.
While the study sheds light on the potential link between education and longevity, further research is needed to fully understand the mechanisms behind this association. Factors such as childhood poverty and access to healthcare likely play a role in both mortality rates and educational outcomes. The researchers emphasize the importance of experimental evidence to validate their findings and to determine the effectiveness of promoting higher education for overall health and well-being. By exploring the impact of education on biological aging, scientists hope to uncover new strategies for promoting healthy longevity and improving quality of life for individuals across all socioeconomic backgrounds.
