Hypothesis
Is abdominal myosteatosis associated with processing speed and general cognition in a multiethnic cohort of middle-aged and older adults?
Conclusion
Abdominal myosteatosis is linked to worse processing speed but not general cognition in a diverse group of older adults.
Supporting Evidence
- The study included a diverse sample of 1,268 adults aged 45-84.
- Myosteatosis was measured using abdominal computed tomography.
- Processing speed was assessed using the Digit Symbol Coding test.
Takeaway
Having too much fat in your muscles can make it harder for older people to think quickly, but it doesn't seem to affect their overall thinking skills.
Methodology
Bivariate analyses and multivariable models were used to assess the relationship between myosteatosis and cognitive measures.
Limitations
The study may not generalize to populations outside the multiethnic cohort studied.
Participant Demographics
Participants were aged 45-84 years, with a mean age of 63, including 52% female and diverse ethnic backgrounds.
