Abstract
The aim of this work is to assess how disability‐free life expectancy (DFLE) has evolved over a decade in England distinguishing three levels of disability, and propose possible explanations for observed changes and differences across gender and severity levels.
We used data from the English Longitudinal Study of Ageing and considered both cross‐sectional and longitudinal samples interviewed from 2002 to 2012. Disability classes were estimated using latent class analysis. DFLE was measured applying the Sullivan’s method. Additionally, years lost due to disability (YLD) were estimated to perform individual‐level analysis and explore the role of BMI and year of birth in explaining changes.
Over the decade, changes in DFLE differed across gender and disability levels. Severe andmoderate disability compressed for women and stayed constant for men. Preliminary evidence showed interactive role of cohort and BMI in changes in YLD, such that high BMI resulted particularly detrimental to younger cohorts.
