In 2018, data were collected through interviews, clinical examinations, neuropsychological tests, and laboratory tests. Diabetes status was defined by self-reported physician-diagnosed diabetes, current use of antidiabetic agents, and fasting blood glucose tests. Global cognitive function was assessed using the Mini-Mental State Examination. Dementia was diagnosed following DSM-IV criteria, and Alzheimer’s disease (AD) was diagnosed following the National Institute on Aging-Alzheimer’s Association criteria. Physical function was assessed by the Short Physical Performance Battery. Data were analysed using multiple logistic and general linear regression models.Results: IFG was found in 267 participants, and diabetes was diagnosed in 658 participants (257 with well-controlled diabetes, 401 with poorly controlled diabetes). Dementia was diagnosed in 166 participants (116 with AD), and physical functional impairment was found in 1973 participants. The multi-adjusted odds ratio (OR) of dementia associated with poorly controlled diabetes (vs without IFG or diabetes) was 2.41 (95% CI 1.52– 3.84), and the OR of AD associated with poorly controlled diabetes was 2.32 (1.34– 4.04). In addition, the adjusted OR of physical functional impairment was 1.40 (1.06– 1.85) for well-controlled diabetes and 1.69 (1.35– 2.12) for poorly controlled diabetes. However, IFG was not associated with cognitive or physical function.Conclusion: The glycaemic control status of diabetes patients was associated with cognitive impairment and physical functional impairment.Keywords: impaired fasting glucose, Alzheimer’s disease, cognitive function, physical functional impairment |
