In order to calculate the likelihood of achieving what they called "exceptional longevity," which they defined as being 90, 95, or 100 years old, the scientists examined data from hundreds of women.
The advantages of maintaining a steady weight for older women were investigated by University of California San Diego (UCSD) researchers in a study on longevity in women. Maintaining a constant weight should be the major goal for older women who want to live to 90 or beyond.
According to a recent multi-institutional study, older women with steady body weight beyond age 60 had a higher likelihood of living to 90.
In the Journal of Gerontology: Medical Sciences, the study was published.
What the study says
54,437 women from the Women’s Health Initiative participated in the study. The researchers examined women’s weight fluctuations over time and related them to their ages.
Researchers discovered that women who lost weight unintentionally had odds of living to 90 that were 51% lower. Weight gain of 5% or more did not increase extraordinary lifetime, despite the fact that weight loss was linked to decreased longevity. This emphasises the significance of maintaining a steady weight.
The researchers discovered that 56.3% of women who kept a steady weight lived to be at least 90 years old. They did this by removing any women who passed away before the first year of the three-year weigh-in (to prevent pre-existing health issues from influencing results).
Women who unintentionally lost 5% or more of their body weight had a lower likelihood of living to 90.
Women who had weight loss of more than 5% (for any reason) at the 3-year checkup had 33% lower odds of reaching 90, 35% lower odds of reaching 95, and 38% worse odds of reaching 100, according to the authors.
The odds of the women trying to lose weight reaching 90 were reduced by 17% regardless of whether the weight loss was purposeful or accidental. Dietary adjustments and an increase in exercise were two factors in weight loss that was done on purpose.
The likelihood of reaching 90 was reduced by 51% for the women who did not intentionally lose weight. The women listed stress and illness as two causes of unintended weight loss. On the other hand, a weight gain of more than 5% at the 3-year weigh-in was not connected to a higher likelihood of surviving.
This could change the advise for older women looking to lose weight. Beyond the age of 60, it will be more crucial to place an emphasis on maintaining weight in people who are otherwise in generally good condition.
