Reports a longitudinal analysis linking a combined protein-density and carbohydrate-quality score to frailty-state transitions among US adults aged 50 and older over seven years.

Protein density, carbohydrate quality, and frailty-state transitions among adults aged 50 years or older: a continuous-time multistate analysis of the health and retirement study
Key Takeaways
  • The analysis included 6,982 participants with up to 7.1 years of follow-up and 1,487 recorded deaths.
  • Each 1-SD higher dietary score was associated with lower robust-to-pre-frail transition intensity (HR 0.933; 95% CI 0.875–0.995).
  • Each 1-SD higher dietary score was associated with lower pre-frail-to-death transition intensity (HR 0.809; 95% CI 0.662–0.989).
