One of the major causes of disability and dependency in older people worldwide is dementia. However, few studies have been conducted on determinants of cognitive impairment among people 50 years and older. The purpose of this study was to describe the prevalence and explain determinants of cognitive impairment among adults aged 50 years and older in Thailand. A crosssectional study was conducted from September 2015 to March 2016. The participants was randomly selected from sixteen districts, fourteen provinces across four regions of Thailand. A total of 3021 completed questionnaires were used for analysis. Cognitive impairment was measured by the Montreal Cognitive Assessment (MoCA) and established questionnaire from the study of Global Ageing 2014 (SAGE). The prevalence of cognitive impairment was 23.20%. Four variables were associated with cognitive impairment as aged 65 years and older, female, without spouse, and low frequency of social interaction attended. Multiple logistic regression revealed that aged 65 years and older (AOR: 1.61, 95% CI: 1.35-1.93), female (AOR: 1.41, 95% CI: 1.16–1.70), completed primary school and lower (AOR: 0.73, 95% CI: 0.55-0.96), and low frequency of social interaction attended (AOR: 1.25, 95% CI: 0.98-1.60) were found to be significant predictor of cognitive impairment among adults aged 50 years and older. Annual screening for cognitive impairment of adults aged 50 years and older should be done. Provide health promotion in risk group and care for older cases with impaired cognitive function to achieve well-being in their lives.
