Newswise — Hamilton, ON (February 1, 2022) – A new study has found that greater body fat is a risk factor for reduced cognitive function, such as processing speed, in adults.
Even when the researchers took cardiovascular risk factors (such as diabetes or high blood pressure) or vascular brain injury into account, the association between body fat and lower cognitive scores remained. This suggests other not yet confirmed pathways that linked excess body fat to reduced cognitive function.
In the study, 9,166 participants were measured by bioelectrical impedance analysis to assess their total body fat.
As well, 6,733 of the participants underwent magnetic resonance imaging (MRI) to measure abdominal fat packed around the organs known as visceral fat, and the MRI also assessed vascular brain injury – areas in the brain affected by reduced blood flow to the brain.
The results were…
