More Visceral Fat Means More Cognitive Impairment in Later Life
There is plenty of evidence to link the presence of excess visceral fat tissue with cognitive decline over the course of aging. This fat tissue produces chronic inflammation, among other issues, accelerating all of the common forms of age-related decline. Becoming overweight is a reliable way to raise risk of age-related disease, increase lifetime medical costs, and reduce life expectancy. The more weight carried, the worse the prognosis.
A new study using data from the Trinity Ulster Department of Agriculture (TUDA) ageing cohort study comprising over 5,000 individuals has found that a measure of belly fat (waist:hip ratio) was associated with reduced cognitive function in Irish adults older than 60 years.
