Hypothesis

The study aimed to investigate the association between creatinine-to-cystatin C ratio and frailty, as well as the mediating role of muscle strength.

Conclusion

Higher creatinine-to-cystatin C ratio is associated with a lower risk of frailty, and muscle strength partially mediates this relationship.

Supporting Evidence

  • Higher CCR was associated with lower risk of frailty.
  • The relationship between CCR and frailty was not significant when adding muscle strength.
  • The association between baseline CCR and incident frailty was partially mediated by muscle strength.

Takeaway

This study found that a higher ratio of creatinine to cystatin C can mean less frailty in older adults, and having stronger muscles helps explain this.

Methodology

Cross-sectional and longitudinal analyses with 4-year follow-up of community-dwelling adults aged ≥60 years.

Limitations

The study may not be generalizable beyond the Chinese population.

Participant Demographics

Community-dwelling adults aged ≥60 years.
