Background and Purpose The Montreal Cognitive Assessment (MoCA) has been known as a screening test for detecting mild cognitive impairment (MCI) better than Mini-Mental State Examination (MMSE). However, in previous domestic studies, no significant difference was found in the discriminability between MoCA and MMSE. Researchers have suggested that this might be because older Koreans are less educated than older Westerners. This study was conducted to examine the effect of education on the discriminability of MoCA compared to the MMSE. Methods Participants were 123 cognitively normal elderly, 118 with vascular MCI, 108 with amnestic MCI, 121 with vascular dementia, and 113 with dementia of the Alzheimer’s type. The Korean-MoCA (K-MoCA) and Korean-MMSE (K-MMSE) were administered. Multiple regression analyses and receiver operating characteristic (ROC) curve analyses were performed. Results In all participants, education significantly affected both K-MoCA and K-MMSE scores along with age. The effect of education was re-examined by subgroup analysis after dividing subjects according to the level of education. Effect of education on K-MoCA and K-MMSE was only shown in the group with <9 years of education. ROC curve analyses revealed that the discriminability of K-MoCA to differentiate between vascular MCI and normal elderly was significantly higher than that of K-MMSE. When re-examining subgroups divided by education level, however, this higher discriminability of K-MoCA disappeared in the group with <9 years of education. Conclusions These results indicate no difference in discriminating cognitive deficits between K-MoCA and K-MMSE in Korean elderly with <9 years of education.

“…The MoCA‐K is a tool for screening MCI that was modified and translated into Korean to be suitable for the Korean culture and linguistic characteristics by Kang et al ( 2009 ), based on the original MoCA developed by Nasreddine et al ( 2005 ). This tool comprises items on visuospatial ability/executive function, language ability, memory/delayed recall, attention, abstraction and orientation, amounting to a total score of 30 points.…”

Aim To examine self‐care behaviours among older adults with hypertension and identify related factors, including cognitive function, religious belief and comorbidities. Design A cross‐sectional study. Methods Self‐care behaviours included diet and health. Participants completed a survey including items on demographics, disease‐related characteristics and self‐care behaviours and underwent cognitive function tests. Data were analysed using descriptive statistics, and multiple regression analysis was performed to analyse the factors affecting self‐care. Results Regarding diet behaviour, older religious adults and those with higher scores on the Montreal Cognitive Assessment‐Korean version had higher levels of self‐care scores according to the HBP‐SC. Regarding health behaviour, older adults with no comorbidities had higher levels of self‐care scores according to the HBP‐SC. Conclusion Factors affecting self‐care diet behaviour include religion and Montreal Cognitive Assessment‐Korean version scores and those affecting health behaviour include comorbidities among older adults with hypertension. Therefore, to improve their self‐care behaviours, their religious practices and comorbidities should be considered, cognitive function should be assessed, and tailored education should be provided. Implications for the Profession and/or Patient Care This study investigated factors affecting self‐care behaviours of hypertensive older adults in South Korea. The self‐care was divided into diet and health behaviours. The factors influencing diet behaviour were religion and Montreal Cognitive Assessment‐Korean version scores, and the factor influencing health behaviour was comorbidities. We also investigated self‐care behaviour patterns. Older adults with hypertension were good at controlling alcohol consumption and did not forget to fill prescriptions. However, they were poor at reading nutrition labels to check on sodium content and checking blood pressure at home. Therefore, nurses could develop interventions considering these influencing factors and behavioural patterns to improve self‐care behaviours and enhance health for older adults with hypertension. Impact Hypertension in older adults affects their health conditions and performance of self‐care behaviours. Nurses could assess self‐care based on diet and health behaviours. Additionally, further developing tailored programmes is recommended considering factors like religious belief, cognitive function and comorbidities. Reporting Method This study followed the STROBE guidelines. Patient or Public Contribution This study used a convenience sample of 105 participants aged ≥ 65 years recruited from a Korean hospital.

“…The MoCA is a 30-point test that consists of 32 items where higher scores indicate a better cognition [30]. The Korean version of the MoCA has demonstrated validity and reliability [31].…”

Low-income middle-aged women (LMW) who are vulnerable have various physical and psychosocial problems. They need lifestyle interventions to actively cope with these risk factors. This study used a randomized control group pretest-posttest design. LMW aged from 40 to 60 years were recruited and randomly assigned to an experimental group (n = 31) and a control group (n = 32). The lifestyle interventions for this study, which were implemented for eight weeks, included nutritional management, physical activity, stress management and cognitive function improvement based on King’s goal attainment theory. The measured outcomes were health-promoting behaviors, Type D personality, cognitive function and body composition. The experimental group scored significantly higher than the control group for health-promoting behaviors (effect size (ES) = 0.68~1.27, p < 0.001~0.014) and cognitive function (ES = 0.79~1.31, p < 0.001~0.005). The negative affectivity (ES = 0.70, p = 0.012) and the prevalence of a Type D personality (x2 = 4.39, p = 0.047) and the systolic blood pressure (ES = 0.65, p = 0.019) decreased significantly in the experimental group compared with the control group. Lifestyle interventions for LMW were effective in improving health-promoting behavior, Type D personality traits and cognitive function.
