Abstract

Background: Dementia is a common health problem among older adults. Despite dementia is also a common cause of hospitalization, loss of independence and reduced quality of life, the research on this issue in Vietnam, especially in the community setting, is still limited. Objectives: This study aimed to assess the prevalence of dementia and factors related to dementia in people aged 65 years and older in two communes of Cau Ngang District, Tra Vinh Province. Methods: Descriptive cross-sectional study, conducted on older adults (≥ 65 years old) with permanent residence in two communes Vinh Kim, Thuan Hoa of Cau Ngang District, Tra Vinh Province. The diagnosis of dementia was made in two stages: screening and diagnosis. The MMSE scale was used for the screening stage (cut-off scores were < 24 for literate participants and < 18 for the illiterate participants). The diagnosis stage followed the DSM-5 criteria. Multivariate logistic regression analysis was used to investigate relationships of dementia-related factors. Results: The study included 334 older adults, with mean age of 71.3 (65-93). The prevalence of dementia diagnosed using the DSM-5 was 14.1%. The group ≥ 80 years old was related to dementia with OR = 18.4 (95% CI: 4.8– 70.3), p < 0.001 compared with the group 70-79 years old. Education level classified as illiteracy was related to dementia with OR = 3.3 (95% CI: 1.4 – 7.9), p = 0.006. The group with a history of stroke related to dementia with OR= 7.7 (95% CI: 2.1 – 28.5), p = 0.002. Conclusions: The prevalence of dementia diagnosed as DSM-5 criteria was 11.4%. Factors associated with dementia were older age, education level and history of stroke.
