A recent study published in Nature Aging highlights significant improvements in the physical and mental capabilities of the elderly, particularly in developed countries. The research, led by Professor John Beard from Columbia University, indicates that individuals born in the 1950s are healthier and more vibrant at age 68 compared to those born in the 1940s at age 62.
Beard notes, “For many, 70 can be the new 60,” emphasizing the positive trends in aging. The study compares data from British and Chinese populations, showing that improvements in education, nutrition, and sanitation have contributed to this phenomenon. Medical advancements, such as joint replacements and treatments for chronic diseases, have also played a crucial role in enhancing the functional capacity of older adults.
Despite these encouraging findings, Beard warns that the increase in obesity rates poses a significant threat to these advancements. He states that rising obesity can lead to premature death and frailty in old age. The study analyzed data from nearly 15,000 participants over 60 in the UK and over 11,000 in China, revealing a median birth year of 1940 and 1947, respectively.
Professor Timo Strandberg from Finland supports these findings, noting similar improvements in elderly functional capacity observed in long-term studies in Helsinki. He cautions that while the elderly’s vitality is increasing, the looming issue of obesity could reverse these gains.
