Objective:

To investigate the relationship between different stages of Cardiovascular-Kidney-Metabolic (CKM) syndrome and all-cause mortality in U.S. adults, addressing a critical gap in existing research.

Key Findings:
  • Higher CKM stages are strongly associated with increased all-cause mortality risk, with specific data indicating a significant correlation.
  • Approximately 90.8% of U.S. adults were affected by CKM between 2011 and 2022, highlighting the widespread nature of the syndrome.
  • 15% of U.S. adults have advanced CKD (stage 3 or 4), underscoring the severity of the issue.
Interpretation:

The study highlights the significant impact of CKM syndrome stages on mortality risk, emphasizing the need for integrated management of these interconnected health conditions to inform public health policy.

Limitations:
  • Cross-sectional design limits causal inference, making it difficult to establish direct cause-and-effect relationships.
  • Potential biases in self-reported data may affect the accuracy of the findings.
Conclusion:

Understanding the relationship between CKM syndrome stages and mortality can inform urgent public health strategies to reduce the burden of these conditions in the U.S.
