LONDON, Jan 11 – New British research has shown that carrying extra body fat, especially around the waist, can be linked to a smaller brain size, which may indicate a higher risk of dementia.
Executed by researchers at Loughborough University, the new study looked at 9,652 adults with an average age of 55 and used magnetic resonance imaging (MRI) to measure brain and brain brain volumes.
To look at the possible effect of paying extra attention to these brain volumes, the researchers determined the obesity of the participants by measuring the body index (BMI), a weight-to-height ratio calculated by dividing a person’s weight by the square of their height. . People with a BMI of over 30.0 are considered obesity.
The waist-to-hip ratio of the measured participants, determined by dividing the waist size by the hip circumference. People who have larger abdomen compared to the hips have a higher ratio, with men over 0.90 and women over 0.85 being considered central obese.
The results, published in the journal Neurology showed that after adjustment for other factors that may affect brain volume, such as age, physical activity, smoking and high blood pressure, high BMI participants had a slightly lower gray volume than those with a healthy BMI.
But those with both a high BMI and high waist-to-hip ratio had an even lower degree of gray-brain matter than participants who did not have a high waist-to-hip ratio.
No significant differences were found in the brain volume of white matter.
“Existing research has linked the brain’s shrinkage to memory loss and a higher risk of dementia, but research on whether extra body fat is protective or harmful to brain size has been undoubtedly,” says study author Mark Hamer, PhD. “Our research looked at a large group People and obesity, especially around the middle, can be linked to the brain’s shrinkage. “Gray matter contains most of the brain’s nerve cells and includes brain regions involved in self-control, muscle control and sensory perception. Vitamin contains nerve fibers that connect different parts of the brain.
“Although our study was, over the head, especially in the middle, was associated with lower volumes in the gray matter, it is unclear whether abnormalities in the brain structure lead to obesity or if obesity leads to these changes in the brain,” says Hamer. “We also found links between obesity and shrinkage in specific parts of the brain. This will need additional research, but one day may regularly measure BMI and waist-hip ratio may help determine brain health.” ̵
