Description
Hongli Nie and co-authors ask, in a study published in 2026, whether a simple body measure can flag later memory problems in older adults. The measure, the weight-adjusted waist index, divides waist size by the square root of body weight. Links between body fat and thinking skills have been unclear, so a cheap early sign would help.
The team used a national Chinese survey that followed adults aged forty-five and over from 2011 to 2018. Of 5,333 people, one quarter developed thinking problems over seven years. Higher index values went with higher risk, even after counting other factors, and the top groups faced more risk than the lowest. The authors say the index adds some power to forecasts, though it is no diagnosis on its own. Clinics could compute it from two routine measures.
