Hypothesis
The study aims to explore the relationship between weight-adjusted waist index (WWI) and cognitive performance in older adults.
Conclusion
Increased abdominal obesity, indicated by higher WWI, is linked to deficits in cognitive functions such as learning, memory, and processing speed in older adults.
Supporting Evidence
- Higher WWI was significantly associated with lower scores on cognitive tests.
- The negative association was more pronounced in men.
- The association decreased with advancing age.
- Non-linear threshold effects were observed with stronger correlations above specific thresholds.
Takeaway
If older people have bigger bellies, they might have a harder time remembering things and thinking quickly.
