Risk factors of dementia cognitive symptoms among older patients in Vietnam: A cross-sectional study

Abstract

Background. Dementia has emerged as a significant contributor to declining quality of life and stands as a prominent factor in the increase of disability and dependency among elderly populations globally. This study aimed to explore the relationship between cognitive symptoms of dementia and their risk factors in individuals aged 60 years and older among Vietnamese outpatients who visited Geriatrics Clinic at University Medical Center of Ho Chi Minh city, Vietnam. Methods. 387 participants who were aged ≥ 60 years old were included in the cross-sectional study. Cognitive impairment was assessed by using the Mini Mental State Evaluation (MMSE) questionnaire. The functional limitations in activities of daily living (ADL) and Instrumental Activities of Daily Living (IADL), multimorbidity, and polypharmacy were also evaluated. Frailty was determined by The Canadian Study of Health and Aging Clinical Frailty Scale. Suffering dementia was determined when MMSE score was below 24 and IADL score less than 8. Results. People with dementia cognitive symptoms accounted for 22.74 % of the cohort. The percentage increased with age, and was higher in women than in men. Factors that increased the odds of having dementia symptoms were of older age, female, multimorbidity, Frailty Scale > Grade 4 and ADL dependency. Conclusions. Age, female gender, multimorbidity, frailty and ADL dependency were considered as risk factors of dementia cognitive symptoms among the Vietnamese people aged 60 years and older.
