Note: (1) DI refers to the cumulative deficit index. (2) The samples and observations only include those who were aged 65–105 at their first interviews in the 2002, 2005 and 2008 waves of the CLHLS and had at least one follow-up interview. (3) Except for the proportion of death, which is calculated based on the whole study period, five health outcomes are measured at either 2002, 2005, or 2008 wave of the CLHLS
