Authors' conclusion

Advancing baseline CKM stage, particularly Stages 3 and 4, was associated with increased cancer risk. These findings extend the clinical relevance of the CKM framework beyond cardiovascular and kidney outcomes, underscoring the need for integrated risk assessment and prevention in multimorbid individuals.

Study context

Population
Individuals in Japan with available health checkup data and insurance claims between April 2014 and August 2023, excluding those with prior cancer or missing covariatesparticipants analyzed
Participants
1,390,901 individuals
Exposure
Higher baseline cardiovascular-kidney-metabolic (CKM) stages compared with Stage 0
Outcome
Incident cancer (International Classification of Diseases, Tenth Revision codes C00-C97)
Follow-up
Median 3.4 years

Main finding

As reported in the abstract

CKM Stages 1-4 vs Stage 0Adjusted hazard ratio (95% CI)
first stage of CKM Stages 1-4 (Stage 1)
1.03(0.99–1.08)
second stage of CKM Stages 1-4, respectively
1.02(0.99–1.05)
third stage of CKM Stages 1-4 (Stage 3)
1.25(1.21–1.29)
fourth stage of CKM Stages 1-4 (Stage 4)
1.30(1.25–1.35)

Observational data: associations, not effects.

Further findings

Cancer types and subgroups (age, sex)

The stage-specific association was consistent across cancer types and in analyses stratified by age and sex, with similar patterns observed across subgroups

Sensitivity analyses using alternative CKM definitions

Supported the robustness of the findings
