University of California San Diego researchers have identified a clear link between maintaining a stable weight after age 60 and longer life in women. The study details were reported in the Journal of Gerontology, a respected publication in the field of aging research.
The investigation tracked more than 50,000 women, with a substantial portion—over 30,000—surpassing the 90-year mark. Across many years, participants regularly shared information about their body weight and health, enabling a nuanced look at how weight patterns relate to longevity in later life.
Women who shed at least 5% of their body weight were found to be less likely to reach extreme ages. In cases where weight loss occurred unintentionally, the chances of long life dropped by roughly 51%. Conversely, gaining 5% or more in weight did not show a link to notably longer life. Those who maintained a stable weight as they aged exhibited a 1.2 to 2 times higher likelihood of longevity compared with peers whose weight fluctuated more.
The researchers emphasize that weight loss in aging individuals may signal underlying health issues and could foreshadow a shorter life expectancy. This finding highlights the importance of monitoring weight trends in older adults as part of a broader assessment of health and well-being.
As science continues to explore how lifestyle factors influence aging, the relationship between weight stability, brain health, and overall vitality remains a key area of inquiry. Ongoing studies aim to translate these insights into practical guidance for aging populations seeking to preserve health and independence into advanced years.
