Does Being Heavier Help Frail Elderly Live Longer with Disabilities?

Have you ever wondered if having a higher body mass index (BMI) makes a difference in how long frail older adults live with disabilities compared to those who are not frail? This study dug into the mysterious link between BMI and the age at which people become disabled, stay disabled, and pass away without being disabled.Scientists found that in older adults, being a bit heavier seemed to help those who were frail live longer with disabilities. But here's an interesting twist: this benefit wasn't as obvious in older adults who weren't frail. This study didn't just look at one age group; it considered both younger and older adults. And guess what? The results differed between the two groups. For younger adults, a higher BMI didn't show any clear advantage. Why might this be the case? Well, being heavier might provide some extra energy reserves that can help frail older adults cope better with their health challenges. But for younger adults or those who aren't frail, these reserves might not be as crucial.
