Functional Disability and Its Associated Factors in Older Adults with Diabetes: Impact on Mortality Based on ICF

Project: National Science and Technology CouncilNational Science and Technology Council Academic Grants

Project Details


Background: Most previous studies of health outcomes in adults with diabetes have focused on laboratory indicators and assessment of diabetes complications. These indicators do not necessarily reflect patients’ self-rated physical functioning, activities, and participations. Diabetes is associated with an increased risk of functional decline in older adults. However, to date no studies have investigated the associated factors of functioning in older adults with diabetes by a systematic framework. With the approval of the International Classification of Functioning, Disability and Health (ICF) we could base on a globally agreed systematic framework and classification to explore the problems in functioning of patients with diabetes. Objective: The objectives of this study are three-fold. First, we investigate the associated factors of functional disability in older adults with diabetes based on ICF. Second, we compare the health status between older adults with and without diabetes based on ICF. Third, we compare 3-year mortality risk between older adults with and without diabetes and explore their associated factors based on ICF. Method: This is a prospective study involving participants in the Taiwan National Health Interview Survey (NHIS), 2005 and 2009. Those individuals aged 65 and above will be included in this study. Deaths will be verified by indexing to the National Register of Deaths with a personal identification number for 3 years. We assess factors considered to be associated with functional decline and mortality in older adults with diabetes including the age at diagnosis, use of insulin, other chronic conditions, participations, social support, and health-related behaviors. Statistical analysis: Logistic regression analysis will be performed to assess the association between functional decline and its associated factors. Multivariate Cox’s proportional hazards models will be used to examine the association between mortality and its associated factors. We used the SAS (SAS Institute, Cary, NC) for all analyses.
