Purpose: The aim of this study is to examine the reciprocal causal relationship between social activities and health with reference to the cognitive function level among community-dwelling older adults. Methods: We conducted a longitudinal data analysis using the $4^{th}$ (Time 1) and $5^{th}$ (Time 2) waves from the Korean Longitudinal Study of Ageing adopting cross-lagged panel analysis (CLPA). Results: A total of 3,473 community-dwelling older adults were included in the analysis: 2,053 in the normal cognitive function group, 912 in the mild cognitive impairment group, and 508 in the moderate to severe cognitive impairment group. The CLPA revealed that higher levels of social activities at Time 1 significantly influenced better subjective health perception at Time 2 in all three groups. In addition, better subjective health perception at Time 1 significantly influenced higher levels of social activities at time 2 only in the normal cognitive function group. Conclusion: This study demonstrates that participating in social activities has positive effects on health regardless of the cognitive function level in community-dwelling older adults. This finding suggests that there is a need to develop strategies that can be used to encourage older adults with cognitive decline to maintain participation in social activities.

This study examined the association between marital status and mental health(depression, and suicidal ideation) of Korean adults by age and sex, using 2005 Korean National Health and Nutrition Examination Survey data. Differences of marital status in depression and suicidal ideation were assessed by age and sex-specific prevalence according to each stage of the life course. Our results indicated that adults who divorced, separated, and widowed had significantly higher risk of poor mental health than married adults. Men with no spouse at the stage of middle and older aged are reported higher in depressive symptom than married men. For the suicidal ideation, men with no spouse had higher risk of suicidal ideation through all stage of life course. Women were more likely to report depressive symptom and suicidal ideation than men through all stage of life course. But we could not found the mental health advantage of marriage among Korean women through all stage of life course. Based on findings, the study clearly indicate that the implication of marriage on mental health could be different for adults of different age group and sex.

The purpose of this study is to investigate the effect of aging and dual tasking to the postural control during quiet standing. It was hypothesized that the center of pressure (COP) dynamics would be differently affected by aging and characteristics of the task. Total 60 adults (35 young adults and 25 older adults) participated in this study. They conducted two different standing tasks (dual vs. Nondual) twice in a random order. Variability, complexity, coupling and symmetric index from the left, right and overall COPs were measured by various parameters in nonlinear, linear and frequency analyses methods. Results demonstrated that older adults had worse performance in postural control with decreased complexity in overall sway movement, and increased coupling between left and right limb COP movement, even though there was no significant difference in symmetric index. These tendencies are generally clearer in nonlinear measures at the dual task condition. Results implied that older adults had compensatory strategy in dual tasking which results in simple and combined postural movement patterns.

In this study, we want to investigate the nutrition knowledge, eating habits, and food intake patterns of adults who have a strong preference for sugary snacks or sugary drinks. In this study, 83 students, or 33.1% of the 267 adults, were found to belong to the sugary food group, and the results of the survey were as follows. In terms of the level of eating habits, both male and female adults see significant differences among the groups. In the question of the regularity of the three meals, the quality of breakfast, the balance of meals, the level of consumption of green vegetables, meat, fish and milk, the number of sugars was low, and the number of sugars, instant foods, ham and sausages was high. In terms of nutritional knowledge, both male and female adults had a low number of sugary foods, and there were significant differences among the groups. In terms of the frequency of food intake, the frequency of eating rice and mixed grain rice was low, and the frequency of eating ramen and bread was high.

Purpose: This study aims to determine the association between fear of falling, falls efficacy, and fall prevention behaviors in older adults in outpatient and identify the factors affecting fall prevention behaviors. Methods: This was a descriptive study. A total of 137 older adults aged 60 or older with more than one disease in an outpatients setting were recruited from a university hospital in Seoul. Data were collected from March 11 through April 8, 2016. Results: The experience of a fall was significantly associated with age (t=-2.71, p=.008), gender (𝛘²=14.32, p<.001), education (𝛘²=6.05, p=.049), income (𝛘²=9.93, p=.019), physical activity status (𝛘²=16.84, p<.001), and the number of diseases (t=-2.89, p=.004). Fall experience was not significantly associated with marital status (𝛘²=3.79, p=.285). Multiple regression analysis revealed that the most influential factor of fall prevention behaviors was the fear of falls (β=-.37, p<.001), followed by the number of diseases (β=-.20, p=.013). Conclusion: It is necessary to provide preventive fall education with older adults in outpatients settings considering the fear level of falling and the numbers of accompanying diseases.

Purpose: Based on the health belief model and theory of planned behavior, this study investigated how age group (adolescence and emerging adulthood) moderated the relative effects of perceived susceptibility, perceived severity, and subjective norms on preventive behavior against coronavirus disease 2019 (COVID-19). Methods: This secondary data analysis utilized data from adolescents (n=272) and emerging adults (n=239). Hierarchical multiple regression analysis was performed to test the moderating effect of age group on the relationships among variables. Results: Higher perceived susceptibility (β=.21, p<.001), perceived severity (β=.14, p=.002), subjective norms (friends) (β=.26, p<.001), subjective norms (parents) (β=.44, p<.001), and subjective norms (schools) (β=.28, p<.001) enhanced COVID-19 preventive behaviors. Moderated regression analysis showed that subjective norms (friends and school) impacted preventive behavior in adolescents more than in emerging adults. Conclusion: Given the need to increase perceived susceptibility and severity among adolescents and emerging adults, these findings provide baseline data for designing effective COVID-19 prevention interventions that consider the developmental characteristics of different age groups. Interventions by health centers at universities can strengthen COVID-19 preventive behavior among emerging adults. As adolescents are influenced by friends, their peer roles must be strengthened to enhance adherence to COVID-19 preventive guidelines.

Purpose: This study aimed to develop a self-management mobile app for adults with osteoarthritis based on a self-determination theory to use it as a nursing intervention tool, and to evaluate the effects of the developed mobile app on adults' basic psychological needs, indexes of osteoarthritis, self-management and quality of life. Methods: The 56 participants were randomly assigned to either the experimental group (n=28) or the control group (n=28). The participants of the experimental group used a self-management mobile app for 12 weeks after the pretest, and two posttests were taken at the end of every 6 weeks. The data were analyzed using IBM SPSS/WIN 25.0 for Chi-square test, Fisher's exact test, independent t-test, and repeated measures ANOVA. Results: Basic psychological needs, indexes of osteoarthritis, self-management, and quality of life score of the experimental group were significantly higher than those of the control group. Conclusion: Our findings suggest that mobile app intervention can support improvements in psychological needs, symptoms of osteoarthritis and quality of life in adults with osteoarthritis. It is recommended that the developed mobile app be used as a nursing intervention tool for adults with osteoarthritis in the community.

Background: Numerous studies have consistently demonstrated that depression can be associated with cognitive function decline, primarily focusing on older adults due to the neurodegenerative characteristics of dementia. With persistent depression frequently reported in patients with early-onset or young-onset dementia, this study aimed to assess the impact of depression, specifically the changes in depressive symptoms over time, on the risk of cognitive function decline in middle-aged adults in Korea. Methods: This retrospective study utilized data from the first four waves (2006-2012) of the Korean Longitudinal Study of Aging (KLoSA), focusing on middle-aged adults with normal cognitive function at baseline. Changes in depressive symptoms were categorized into four groups based on the CES-D score, and their association with cognitive function decline was evaluated using a multivariate logistic regression model. Results: Of the initial 10,254 participants, 3,400 were included in the analysis. Depressive status, particularly newly onset (adjusted odds ratio [aOR] 1.96; 95% confidence interval [CI] 1.32-2.93) and persistent depression groups (aOR 5.59; 95% CI 2.90-10.78), were significantly associated with cognitive function decline. In contrast, recovery from depressive symptoms was not significantly associated with cognitive function decline (p=0.809). Conclusions: Our study showed a significant association between changes in depressive symptoms and cognitive function decline in middle-aged Korean adults. This suggests that management of depressive symptoms could be crucial for the prevention of cognitive function decline in this population.

This study aims to analyze older adults's intention to use digital financial services. To verify the purpose, the '2022 Korean Senior Technology Acceptance Panel Survey' data were used. And a shortened Senior Technology Acceptance Model(STAM) reflecting the characteristics of older adults was applied. The results of Structural Equation Model analysis are as follows. First, the lower gerontechnology anxiety, the higher control beliefs reflecting perceived ease of use, self-efficacy and facilitating conditions and the intention to use digital financial services. Second, the health factor had a positive effect on the control beliefs. Third, the higher the control beliefs, the higher the attitudinal beliefs reflecting perceived usefulness and attitude and the intention to use digital financial services. Lastly, the higher attitudinal beliefs, the higher the intention to use digital financial services. The results suggest the need for interventions that can relieve gerontechnology anxiety and strengthen positive perceptions about control beliefs and attitudinal beliefs in order to increase older adults's intention to use digital financial services.
