Association of 3-year change in frailty index with risk of all-cause mortality among older Chinese population: a national cohort study.

ABSTRACT:

Background

Evidence on the association of dynamic change in frailty index (FI) with risk of all-cause mortality in the older Chinese population is limited. This study aimed to explore the association of 3-year change in FI with risk of all-cause mortality in an older Chinese population.

Methods

We analyzed the data of 4969 participants from the Chinese Longitudinal Healthy Longevity Survey. The primary outcome was all-cause mortality, which was a binary variable and defined as completed data and censored data. Cox proportional-hazard models were used to assess the association of 3-year change in FI with risk of all-cause mortality by using hazard ratios (HRs) and 95% confidence intervals (CIs). Subgroup analyses were conducted to explore the association of 3-year change in F
