Prevalence and associated factors of cognitive impairment and poor sleep quality among community-dwelling older adults in northern Thailand

Abstract

Background: Early detection of cognitive impairment and poor sleep quality are necessary to prevent dementia and the improve the quality of life further. Thstudy aimed to investigate the cognitive impairment and poor sleep quality in the community-dwelling older adults and its association with socio-demographic and health characteristics. Methods: A cross-sectional study of 1,180 people in Northern Thailand aged 60 years and above was conducted in 2017. Mental State Examination-Thversion (MSET10) was used to measure cognitive function while the Pittsburgh Sleep Quality Index (PSQI) assessed sleep quality. Multiplogistic regression was used to analyze associations. Results: The prevalence of CI in older adults was 52.45% (95% CI: 49.64-55.42) which increased with age. The prevalence of poor sleep quality wa44.15% (95% CI: 1.29-47.03). Age, illiteracy, hypertension, comorbidities of hypertension and diabetes, alcohol consumption, lack of exercisand depression were significantly associated with increased risk of CI, while being single, comorbidities of hypertension and diabetes, and expression were significantly associated with poor sleep quality. Conclusion: The rate of CI and poor sleep quality in older adults was relatively high in Thailand. Early detection of CI and poor sleep quality and screening foall risk factors are important to improve in access to service, optimization of medical management, reduction in risk factors, and increased quality of life in older adults.
