Higher risk of dementia in English older individuals who are overweight or obese

This cohort study investigated the relationship between obesity and dementia risk in older adults from the English Longitudinal Study of Ageing. Results showed that individuals with obesity had a 34% higher risk of developing dementia compared to those with normal weight. Women with abdominal obesity faced a 39% increased risk. The study highlights how excess body fat, particularly around the waist, contributes to dementia through pathways like inflammation and metabolic dysfunction. These findings underscore obesity as a modifiable risk factor for dementia, with implications for public health strategies.

Maintain a healthy weight and reduce abdominal fat through regular exercise, balanced eating, and monitoring weight. These steps not only support general health but may also reduce the risk of cognitive decline and dementia, based on consistent associations found in this study.
