Key result
Each 1 m/s increase in estimated pulse wave velocity was associated with a 50% higher risk of chronic kidney disease (OR 1.50, 95% CI 1.47-1.54, p<0.0001).
Why the study?
Limited data on the correlation between estimated pulse wave velocity and chronic kidney disease necessitated further investigation into their association.
Does higher estimated pulse wave velocity associate with an increased prevalence of chronic kidney disease in adults?
Cross-Sectional (n=41,411)
Yes
Does higher estimated pulse wave velocity associate with an increased prevalence of chronic kidney disease in adults?

Higher estimated pulse wave velocity is significantly associated with an increased prevalence of chronic kidney disease, suggesting its potential utility as a non-invasive marker for CKD risk assessment.
ePWV was associated with CKD prevalence in NHANES adults; hypothesis-generating for arterial stiffness as a CKD marker, prospective studies needed.
Background: Limited data on the correlation between estimated pulse wave velocity (ePWV) and chronic kidney disease (CKD) necessitate further investigation. This study aims to explore the association between ePWV and the prevalence of CKD. Methods: A cross-sectional study was conducted with 41,411 participants from the 1999-2020 National Health and Nutrition Examination Survey (NHANES). ePWV was calculated using an established equation from the Reference Values for Arterial Stiffness Collaboration, incorporating age and mean blood pressure. CKD prevalence was assessed as the primary outcome. Weighted logistic regression and linear models were applied for statistical analysis, with Restricted Cubic Splines (RCS) used to evaluate potential nonlinear associations. Subgroup analyses were conducted to assess variations and ensure the robustness of results. Results: Higher ePWV was consistently associated with an increased prevalence of CKD. RCS analysis identified a significant positive nonlinear relationship. Subgroup analyses revealed sex-based and glucose metabolism abnormality-based differences, highlighting interactive correlations that provided further insights into the ePWV-CKD relationship. Conclusion: This study demonstrates a strong positive association between ePWV and CKD prevalence, underscoring the importance of monitoring arterial stiffness. The use of RCS and subgroup analyses enriched the findings and offered valuable directions for future research.

Li et al. (2025) conducted a cross-sectional in Chronic kidney disease (n=41,411). Estimated pulse wave velocity (ePWV) vs. Lower ePWV was evaluated on Prevalence of chronic kidney disease (OR 1.50, 95% CI 1.47-1.54, p=<0.0001). Each 1 m/s increase in estimated pulse wave velocity was associated with a 50% higher risk of chronic kidney disease (OR 1.50, 95% CI 1.47-1.54, p<0.0001).
