Hypothesis
Does excess adiposity without metabolic abnormalities reflect a benign phenotype regarding arterial stiffness?
Conclusion
Excess adiposity and metabolic abnormalities are independently associated with increased arterial stiffness, indicating that metabolically healthy individuals with overweight and obesity are not benign groups.
Supporting Evidence
- Individuals with obesity and metabolic abnormalities had the highest arterial stiffness index.
- Participants with normal BMI and metabolic abnormalities had similar arterial stiffness to those who are overweight without metabolic issues.
- The study included a large sample size of 162,590 participants, enhancing the reliability of the findings.
Takeaway
Being overweight or obese can make your blood vessels stiffer, even if you don't have other health problems. This means you still need to be careful about your health.
Methodology
The study analyzed data from UK Biobank participants with recorded BMI and arterial stiffness index, using multivariate-adjusted linear regression.
Potential Biases
Potential misclassification bias from exposure measurements and residual confounding cannot be eliminated.
Limitations
The study may not be representative of the entire UK population and is subject to healthy volunteer selection bias.
Participant Demographics
Mean age of participants was 57 years, with 55% female and a majority being of White ethnicity.
