A recent study from Ireland has found that belly fat is associated with a lower cognitive functioning in older adults (60 years and older).1 The study may have profound implications for a global dementia population that is predicted to increase 3-fold by 2040.

Research shows that overweight individuals underperform normal weight controls on tests of memory and visuospatial ability

Previous research has seen that overweight individuals under-perform normal weight controls on tests of memory and visuospatial ability. That these findings hold true for older adults has not been as thoroughly studied.

Concern for the “world at large’ (pun intended)

This is concern not just for Ireland, but the industrialized world at large is experiencing the largest increase in healthcare needs coming from a rapidly growing elderly population, as the baby boomer generation begins to enter into old age. Obesity is a central concern for this patient population. In Ireland over 50 percent of those over 50 years of age are classified as obese, with only 16% of men and 26% of women reporting healthy weight. These trends are similar for the United States.

Research looked at data from the Trinity Ulster Department of Agriculture (TUDA) aging cohort study

The research study looked at data from roughly 5,000 individuals as part of the Trinity Ulster Department of Agriculture (TUDA) aging cohort study. The study looked at how waist-to-hip ratio was connected to cognitive performance. Waist-to-hip ratio is a measurement which indicates visceral adiposity, or belly fat. It is generally known that this particular type of body fat is associated with increased metabolic risk, cardiovascular disease and inflammation.

Waist-to-hip ratio was associated with decreased cognitive function

The waist-to-hip ratio was associated with decreased cognitive function. However, the BMI (body mass index) was seen as a protective measure of cognitive function. The explanation for this has to do with BMI being a cruder measurement of body fat, that doesn’t consider fat-free body mass (muscle), which in this case may be a protective element to cognitive health.
