Objectives This study examined the associations between digital literacy and self-rated health (SRH), depression, and life satisfaction among older adults in the Republic of Korea.
Methods Data were obtained from the 2023 National Survey of Older Koreans (n=9,951). Digital literacy was evaluated based on participants’ ability to use 8 smartphone functions and their perceived difficulty adapting to a digital society. Dependent variables included SRH, depression (measured using the short form of Geriatric Depression Scale), and life satisfaction (assessed through a composite score across 7 domains). Multiple logistic regression was applied for SRH and depression, while linear regression was conducted for life satisfaction, adjusting for sociodemographic and health-related covariates.
Results Higher digital literacy was significantly associated with better SRH and greater life satisfaction. Compared to participants with no digital skills, those with moderate or high digital literacy had higher odds of reporting good SRH and significantly higher life satisfaction scores. Older adults who reported difficulty adapting to a digital society demonstrated significantly lower SRH and life satisfaction. However, after adjusting for covariates, the association between digital literacy and depression was not statistically significant.
Conclusion Higher digital literacy is linked to better SRH and greater life satisfaction. Moreover, digital literacy reduced the explanatory power of socioeconomic variables, suggesting that it serves as an important behavioral determinant. These findings underscore the importance of promoting digital literacy as a means of improving health equity and well-being in aging populations.

Objectives Social activities are important and influential factors for healthy aging. However, limited information is available regarding the associations of the type and intensity of social participation with health and well-being. This study aimed to investigate how various types of social activities are associated with several dimensions of health outcomes. Methods: This cross-sectional study utilized data from the Seventh Korean Longitudinal Study of Aging, which included 5,526 adults aged 60 years and older. Multivariate linear regression analysis was employed to analyze the associations of social activities with depression, self-rated health, and life satisfaction. Additionally, subgroup analyses by sex and age were performed. Results: Among the participants, 73.5% reported involvement in at least 1 of the 4 types of social engagement. After adjustment for all covariates, individuals who participated in any social activity reported better self-rated health and higher life satisfaction compared to those who did not participate. However, the intensity of engagement in different social activities had varying impacts on subjective health outcomes. An increased level of participation was associated with a lower rate of depression and improved self-rated health. However, no significant differences were observed in the relationship between the intensity of participation in activities (with the exception of alumni societies or family councils) and life satisfaction. Conclusion: This study suggests that to improve their health, older adults in the Republic of Korea should not only engage in social activities but also do so actively and regularly.

Objectives This study investigated the association between living arrangements and healthrelated quality of life (HRQoL) in older people. Methods: A secondary analysis was conducted of 6,153 participants (aged ≥60 years) from the seventh Korean National Health and Nutrition Examination Survey (2016 to 2018). HRQoL was measured using the 3-level version of the EuroQol 5-dimensional questionnaire. The chi-square test, t-test, and multiple regression were used, applying sampling weights for the analysis. Results: The proportion of respondents living alone was 18.0%, with a higher prevalence among women and older age groups (p<0.001). The overall HRQoL was lower in groups living alone than in groups living with others (p<0.001). Older people living alone showed higher impairments in all dimensions of the 3-level version of the European Quality of Life 5-Dimensional Questionnaire (EQ-5D-3L) than those living with others, including mobility (p<0.001), self-care (p<0.001), usual activities (p<0.001), pain/discomfort (p<0.001), and depression/anxiety (p<0.001). Problems with mobility were most prevalent (42.8%), followed by pain/ discomfort (41.9%) in respondents living alone. Living alone was significantly associated with a lower HRQoL index score (b=–0.048, p<0.001) after adjusting for age, gender, education, exercise, perceived stress, and perceived health status. Conclusion: Living alone was negatively associated with HRQoL. Based on this study, future care planning for older people should consider their living arrangements. The need to strengthen and expand care programs targeting those living alone should also be addressed.

<sec>
<title>Results</title>
<p>To examine the factors affecting body image discordance as observed in 43.1% of participants, the group was subdivided into underestimation and overestimation. There were 36.0% of participants that were body image discordant underestimators and 7.1% were overestimators. Multivariate logistic regression analysis showed that the underestimators tended to be men, graduated from high school, married, current/ex-smokers, ex-drinkers, had between 5 to 9 hours sleep (inclusive), had fair to good self-rated health, and demonstrated healthy weight control behavior, relative to the reference group. In comparison, overestimators tended to be in the 19–29 year group and had signs of depression. The OR of individuals who were men, married, and had healthy weight control behavior was significantly lower in the overestimators group.</p></sec>

Objectives
The aim of this study was to identify the effects of community-based home healthcare projects that influence service performances with regard to Korean national long-term care insurance services in older adults. Methods
The project's applicants were 18 operational agencies in national long-term care institutions in Korea, and participants were care recipients (<i>n</i> = 2263) registered in long-term care institutions. We applied our healthcare system to the recruited participants for a 3-month period from October 2012 to December 2012. We measured the community-based home healthcare services such as long-term care, health and medical service, and welfare and leisure service prior to and after applying the community-based home healthcare system. Results
After the implementation of community-based home healthcare project, all community-based home healthcare services showed an increase than prior to the project implementation. The nutrition management service was the most increased and its increase rate was 628.6%. A comparison between the long-term care insurance beneficiaries and nonbeneficiaries showed that health and medical services’ increase rate of nonbeneficiaries was significantly higher than beneficiaries (<i>p</i> < 0.001). Conclusion
Our community-based home healthcare project might improve the service implementation for older adults and there was a difference in the increase rate of health and medical services between Korean national long-term care insurance beneficiaries and nonbeneficiaries.

Objectives
This study aims to examine the effectiveness of a 6-month lifestyle modification program on the improvement in metabolic syndrome (MetS) status and in stages of change for lifestyle behaviors associated with MetS among Korean older adults. Methods
A lifestyle modification program was developed based on the transtheoretical model. The program consisted of health counseling, education classes, a self-management handbook, newsletters and a health diary. Older adults aged ≥60 (<i>n</i> = 480) with MetS were randomly assigned to the intervention group (IG) or the comparison group (CG). The IG received a comprehensive 6-month lifestyle modification intervention, while the CG received minimal information on MetS and lifestyle modification. Health examination and selfadministered survey were conducted before and after the intervention to determine the effectiveness of the program. Results
After the intervention, the prevalence of MetS decreased to 38.1% in the IG and 52.4% in the CG (<i>p</i> = 0.046). The IG improved abdominal obesity (<i>p</i> = 0.016), blood pressure (<i>p</i> = 0.030), and triglyceride (<i>p</i> = 0.005) more than the CG did. The IG demonstrated significant improvements in the behavioral stages for portion control (<i>p</i> = 0.021), balanced diet (<i>p</i> < 0.001) and adequate intake of fruits and vegetables (<i>p</i> = 0.012). The IG reduced the prevalence of abdominal obesity (OR = 2.34) and improved MetS status (OR = 1.79) better than the CG. The IG were more likely to advance from preaction stages at baseline to action stage at post-intervention for portion control (OR = 3.29) and adequate intake of fruits and vegetables (OR = 2.06). Conclusion
Lifestyle modification can improve the MetS status and behavioral stages in older adults.

Objectives
The present study investigated associations between income and intake of nutrients and food in adults (n = 11,063) from the fourth Korea National Health and Nutrition Examination Survey 2007–2009. Methods
To examine relationships between individual dietary intake and anthropometric measures and family income, multiple linear regression models were constructed for each outcome variable. All models were adjusted for age, education, energy intake, smoking, body mass index, and physical activity. Results
For men, intakes of protein, calcium, phosphorus, potassium, and vitamin C were lower in low-income compared to high-income groups. For women, intakes of protein and niacin were lower in low-income groups. Lowest income group ate less dairy products in men and less fruits and fishes or shellfishes in women. Conclusion
Low-income groups had severe food insecurity and low diet quality compared to high-income groups. The study results will provide direction for public health efforts regarding dietary intakes according to economic status among Korean men and women.
