Purpose: The aim of this study was to identify the participation rate of the National Health Screening Program (NHSP) and its influencing factors by cognitive function level in Korean older adults. Methods: This study was a secondary analysis using data from the survey of the Korean Longitudinal Study of Aging in 2016. The data were analyzed using 𝑥² test and multiple logistic regression. Results: The participation rates of the NHSP in the mild cognitive impairment group (79.6%) and the suspected dementia group (58.0%) were lower than the normal cognitive function group (88.1%). The factors influencing NHSP varied by cognitive function level. Especially, in the suspected dementia group, higher participation rates of the NHSP were associated with living in rural areas, enrollment in private health insurance, no depressive symptoms, participation in social activities, and no living with children. Depression and participation in social activities influenced participation in NHSP in all groups. Conclusion: This study suggests that interventions differentiated by cognitive function level are important for increasing the participation in the health screening.

The current study aims to examine whether dementia service utilization is associated with cognitive function and whether health literacy moderates the relationship between dementia service utilization and cognitive function. Data were drawn from the 2016 Dementia Literacy Survey collected by K University. The final analytic sample included 522 community-dwelling older Koreans aged 60 to 79. Results from multivariate regression analyses showed that both dementia service use and higher levels of health literacy were related to better cognitive function and that health literacy had significant moderating effects. When older adults used dementia service, those with higher levels of health literacy reported higher levels of cognitive function than those with lower levels of health literacy. Our findings suggest that health literacy plays an important role in determining the cognitive health benefits arising from dementia service utilization.

This study was conducted to analyze the mediating effect of health status and the moderating effect of economic activity in the relationship between depression and cognitive function of the elderly. For this, the data of 2017 National survey of Older Koreans that was collected all over country by Korea Institute for Health and Social Affairs were analyzed using Structural Equation Model for statistical analysis method. The results are as follows. First, the elderly's depression was found to have a negative effect on cognitive function and health status. Second, the health status of the elderly was found to have a positive effect on cognitive function. Third, a significant mediating effect of health status was founded in the relationship between depression and cognitive function. Fourth, the moderating effect of the elderly's economic activity was found in the path through which depression affects health status and health status affects cognitive function. Based on these research results, implications of social welfare were suggested.

Objectives: Previous studies have found that the oral health of seniors can affect their physical nutrition and quality of life (QoL). Additionally, poor oral health can lead to the development of dementia, which is associated with decreased cognitive function. This study aimed to examine the impact of geriatric oral health (GOH) on the QoL of Korean seniors and the mediating effects of cognitive function. Methods: We used data from the seventh Korean Longitudinal Study of Aging conducted in 2018. In total, 4049 seniors were included in our study. We analyzed the impact of GOH on QoL according to 5 mediating domains of cognitive function and control variables. To examine each path of mediating effects, bootstrapping with 5000 iterations was performed with 95% confidence intervals. Results: Our findings revealed that good GOH had a positive effect on the QoL of seniors. Also, better GOH corresponded to a higher degree of cognitive function within all 5 domains: orientation, memory registration, attention/calculation, memory recall, and language and visuospatial ability. In addition, 3 domains of the 5 domains (attention/calculation, memory recall, and language and visuospatial ability) had significant mediating effects on the relationship between GOH and QoL. Conclusions: This study suggests that adequate management of GOH is crucial for promoting a better QoL and a high degree of cognitive function among seniors. To prevent cognitive impairment, such as dementia, future studies should take a more targeted approach by examining data according to each cognitive domain and various socio-demographic factors.

Objectives: This study aimed to evaluate the association between dental implants and cognitive function in community-dwelling older adults. Methods: Data were collected from the baseline survey (2016-2017) of the Korean Frailty and Aging Cohort Study. The study sample comprised 1115 community-dwelling people aged 70 years to 84 years who had 0-19 natural teeth. Dental implants and natural teeth were identified by panoramic radiography, while the cognitive function was assessed by the Korean version of the Mini-Mental State Examination (MMSE-KC). The association between dental implants and cognitive function was analyzed by multiple linear regression. Sensitivity analysis was performed to test for potential bias. Results: The mean number of natural teeth in the study population was 9.50 (standard deviation [SD], 6.42), and the mean MMSE-KC score was 24.93 (SD, 3.55). In the simple univariate analysis, tooth replacement, age, sex, smoking status, alcohol consumption, body mass index, osteoporosis, number of natural teeth, periodontitis, chewing discomfort, tooth-brushing frequency, education level, monthly household income, participation in economic activity, living alone, and marital status had a significant impact on the association. After adjusting for confounders, the association between dental implants and cognitive function remained significant (B, 0.85; standard error, 0.40; p<0.05). Age, body mass index, periodontitis, tooth-brushing frequency, and education level were also significantly associated with cognitive function. The results of the sensitivity analyses were consistent with those of the primary analysis. Conclusions: Dental implants were associated with cognitive function in older adults living in the community. Dental implants as tooth replacements may play a role in preserving cognitive function.

Objectives : Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects. Methods : To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis. Results : Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R²=0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter. Conclusions : In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.

Purpose: This study was to identify the relations among ADL, self-efficacy, physical activity and cognitive function in elders. Methods: A total of 257 subjects aged between 60 and 92 were selected through convenient sampling. Data were collected with a self-reported questionnaire from November 1 to November 30, 2008. Collected data were analyzed with SPSS/WIN 15.0. Results: Differences in ADL, self-efficacy, physical activity, and cognitive functions according to general characteristics were as follows. ADL was significantly different according to age, cohabitation, recognition on health, and successful aging. Self-efficacy was significantly different according to cohabitation, recognition on health, and successful aging. Physical activity was significantly different according to age, educational level, cohabitation, and cognition on health. Cognitive function was significantly different according to age, educational level, job, and recognition on health. The correlation coefficient (r) of the ADL variables was .565 for self-efficacy, .633 for physical activity and .460 for cognitive function. Conclusion: Findings of this study may be useful in understanding the health status of community-dwelling elders and developing more specific health promotion programs.

This study was designed to investigate the content of health behavior and to examine factors determining health behavior of nursing students(n=159) in relation to sociodemographic and cognitive variables. Cognitive variables were categorized into saliency of health, susceptibility to illness, and health locus of control. Data analysis prodecure included factor analysis and stepwise multivariate regressions using health behavior as dependent variables. Analysis showed; 1. As a whole, nursing students showed a tendency of lack in positive health behavior, especially in diet-related health behavior. 2. Multiple regression analysis revealed that the factors such as grade, saliency of health, and birth place were to be independently and significantly associated with health behavior: Upper grade students, high level of saliency, urban-born students tend to take health behavior positively. 3. The most influential factor among them was grade, but cognitive inspite of stereotype, poorly impact on health behavior with the exception health. We can guess the effect of education indirectively from these findindgs, but longitudinal studies need to consider the direct effect of education. The results also indicate that the respondents should be encouraged to take health behavior positively. The studies including more other cognitive variables would be conducted for the nursing students in relation to health behavior.

Objectives: The purpose of this study was to investigate the effect of handgrip strength level on cognitive impairment in hypertensive patients. Methods: This study used the first to eighth year data of the Korean Longitudinal Study of Aging (KLoSA). Of the 10,254 respondents who participated in the basic survey, respondents were included that they were diagnosed with high blood pressure and had no cognitive impairment. The handgrip strength was based on the highest value of handgrip strength for both hands. Cognitive function using MMSE results and 23 points or less were defined as cognitive impairment. Cox models were conducted to estimate the hazard ratios (HRs) of cognitive impairment in relation to handgrip strength adjusting for covariates. Results: In the case of hypertension patients, the probability of cognitive decline decreased by 3.0% every time the maximum handgrip strength increased by 1 unit. In the analysis by age, under the age of 64 had a 1.8% decrease in the probability of cognitive decline whenever the maximum handgrip strength increased by 1 unit, and a 3.6% decrease in those over the age of 65. In the gender analysis, male had a 3.2% decrease in the probability of cognitive decline for every 1 unit increase in the maximum handgrip strength, and female had a 2.6% decrease. Conclusions: The results of this study are expected to be used as basic data for the development of interventions to prevent cognitive decline in hypertensive patients by identifying the effect of handgrip strength level on cognitive decline. It is also expected to be used as basic data for health education on the necessity of increasing muscle strength for hypertension patients in the community.
