In young, healthy men, a higher body mass index means the heart contributes more to blood pressure increases during stress, while a larger waist-to-hip ratio means less contribution. This finding is from the abstract summary - full study details were not available
Scientific Claim
In healthy young men aged 18-22, the ratio of cardiac output change to mean arterial pressure change during mental stress is positively associated with body mass index and inversely associated with waist-to-hip ratio.
Original Statement
“The delta CO/delta MAP ratio, i.e., relative contribution of cardiac output for the stress-induced increase in mean arterial pressure, showed a strong positive association with body mass index (p = 0.004), but was inversely related to the waist/hip ratio (p = 0.002).”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The abstract uses 'positive association' and 'inversely related', which correctly describes observational study findings without implying causation.
