Incremental predictive value of intrinsic capacity and environmental characteristics in the risk prediction of incident disability.

ABSTRACT:

Objective

To examine the incremental value of intrinsic capacity (IC) and environmental characteristics in the risk prediction of disability.

Method

Secondary analysis was performed on a longitudinal sample of individuals aged 50 years or above. The selected subsample was ambulant and cognitively intact, and did not have any disabilities in instrumental activities of daily living (IADL) at baseline. A set of 18 indicators were first used to assess conditions associated with declines in IC and environmental characteristics. Participants were then followed up for approximately one year, and the IADL status (i.e., disabled or not) was treated as the outcome variable in the logistic regression models. The incremental predictive value of IC was examined by comparing the baseline
