Karger AG, Basel. Introduction: Mild cognitive impairment (MCI) is a transitional stage between normal cognition and dementia. A review showed that 10-15% of those with MCI annually progressed to Alzheimer's disease. Objective: This study aimed to investigate the prevalence and risk factors associated with MCI as well as the characteristics of cognitive deficits among older people in rural Thailand. Methods: A cross-sectional study in 482 people who were 60 years old and over was conducted in northern Thailand. The assessments were administered by trained occupational therapists using demographic and health characteristics, Mental Status Examination Thai 10, Activities of Daily Living - Thai Assessment Scale, 15-item Geriatric Depression Scale and the Montreal Cognitive Assessment-Basic (MoCA-B, Thai version). Results: The mean age of MCI was 68.3 ± 6.82 years, and most had an education ≤4 years. The prevalence of MCI in older people was 71.4% (344 out of 482), and it increased with age. Low education and diabetes mellitus (DM) were the significant risk factors associated with cognitive decline. Older people with MCI were more likely to have an education ≤4 years (RR 1.74, 95% CI 1.21-2.51) and DM (RR 1.19, 95% CI 1.04-1.36) than those who did not. The 3 most common cognitive impairments according to MoCA-B were executive function (86%), alternating attention (33.1%) and delayed recall (31.1%). Conclusion: The prevalence of MCI in older Thai people in a rural area is high compared with that in other countries. The explanation might be due to low education and underlying disease associated with MCI. A suitable program that can reduce the prospects of MCI in rural Thailand is needed. 2020-10-14T08:44:48Z 2020-10-14T08:44:48Z 2020-01-01 Journal 16645464 2-s2.0-85083254232 10.1159/000506279 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85083254232&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/70926
