Older adults show slower aging than previous generations

A recent study from the Robert N. Butler Columbia Aging Center at Columbia University’s Mailman School of Public Health highlights a remarkable improvement in the physical and mental health of older adults in England compared to earlier generations.

Instead of focusing only on the presence of diseases, the researchers used a broader approach, assessing people’s overall functioning. This included their ability to think clearly, move effectively, handle emotions, and use their senses.

The study, published in Nature Aging, analyzed data from the English Longitudinal Study of Aging and found that today’s older adults show significantly better physical and mental abilities than those of the same age from earlier decades.

John Beard, a professor at Columbia University and the study’s lead author, noted that the improvements were striking.

For instance, a 68-year-old born in 1950 demonstrated a similar level of functioning to a 62-year-old born in 1940, while individuals born in 1940 outperformed those born in 1930 or 1920.

Beard explained that the differences become even more pronounced when comparing people born decades apart. A person born in 1950 likely functions much better than someone born in 1920 would have at the same age.

Similar findings emerged from an analysis of data from the China Health and Retirement Longitudinal Study (CHARLS), though the Chinese data covered a shorter time span. This suggests that the trend of improving health among older adults may not be limited to England.

According to Beard, these changes are likely the result of a combination of factors. Advances in education, improved nutrition, and better sanitation throughout the 20th century have had a lasting impact on people’s health.

Medical progress, such as joint replacements and more effective treatments for chronic illnesses, also played a major role.

However, the researchers caution that these findings may not apply everywhere or to every group. For instance, the same trends might not be observed in the United States or among disadvantaged populations. Beard emphasized that while these results are encouraging, future progress is not guaranteed.

Factors like rising obesity rates could slow or even reverse these gains. Additionally, some groups—such as those with more economic advantages—might benefit more than others.

The magnitude of the improvements still surprised the researchers, especially when comparing people born after World War II with earlier generations. “For many people, 70 really may be the new 60,” Beard remarked.

Jay Olshansky, an aging expert from the University of Illinois, praised the study for its optimistic implications. He noted that the findings demonstrate how intrinsic capacity—the key abilities that people value as they age—can be improved.

According to Olshansky, this evidence shows that medical science has the potential to enhance these abilities, offering hope for healthier aging in the future.

While the findings suggest a promising shift in the experience of aging, they also highlight the need to address challenges, such as inequalities and emerging health risks, to sustain these positive trends for future generations.
