Life expectancy among older adults with or without frailty in China: multistate modelling of a national longitudinal cohort study.

ABSTRACT:

Background

Little is known about life expectancy (LE) with or without frailty. We aimed to estimate the total LE and duration of the state of frailty in China.

Methods

This study included older adults aged 65 years and older from the Chinese Longitudinal Healthy Longevity Study (CLHLS). Frailty status was classified into robust, pre-frailty and frailty based on a cumulative deficit model. Total and specific frailty state LEs at 65 years of age were estimated and stratified by demographic characteristics, behaviours, and psychosocial factors using continuous-time multistate modelling.

Results

The total LE of older adults aged 65 years in China was 14.74 years on average (95% CI: 14.52-14.94), of which 4.18 years (95% CI: 4.05-4.30) were robust, 7.46 years (95% CI: 7.31
