Objectives: Sarcopenia is one of the most representative factors of senescence, and nutritional status is known to affect sarcopenia. This study was performed to analyze the relationships between energy and protein intake and sarcopenia. Methods: The study subjects were 3,236 individuals aged ≥65 that participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2008 ~ 2011. General characteristics and anthropometric and 24-hour dietary recall data were analyzed. Sarcopenia was diagnosed using a formula based on appendicular skeletal muscle mass (ASM) and body weight. Logistic regression was performed to determine relationships between sarcopenia risk and energy and protein intakes. Results: For energy intake, the odds ratio (OR) of sarcopenia in women was significantly higher those with the lowest intake [OR = 1.680, 95% confidence interval (CI) = 1.213-2.326] than those with the highest intake (P for trend = 0.001). Regarding protein intake per kg of body weight, the odds ratio of sarcopenia was significantly higher for those that consumed < 0.8 g/kg of protein daily than those that consumed > 1.2g/kg for men (OR = 2.459, 95% CI = 1.481-4.085) and women (OR = 2.178, 95% CI = 1.423-3.334). Conclusions: This study shows a link between sarcopenia and energy and protein intake levels and suggests that energy and protein consumption be promoted among older adults to prevent sarcopenia.

Wearing a mask is essential during the ongoing COVID-19 pandemic. For this study, an online survey was conducted on the actual use of masks among adults in their twenties and older. We used 389 questionnaires for the final analysis, excluding insincere or incomplete questionnaires. We then analyzed the responses using descriptive statistical analysis, frequency analysis, t-test, and ANOVA. More than half of the respondents indicated that they wore a mask for five to ten hours a day, with KF masks being the most frequently used. Participants who most frequently used cloth masks were more likely to consider color, design, and eco-friendliness, while those who used KF masks were more concerned with price and safety. There was no significant difference in purchase satisfaction between mask types, but the purchase intention was higher for KF masks. When purchasing a KF mask, there were significant differences across genders in terms of price and eco-friendliness preferences. There were also significant differences across age groups in price, eco-friendliness, skin irritation, and comfort preferences. Previous studies have shown a significant difference in gender and age in terms of preferred mask colors and designs. However, this survey found no significant difference across these categories. These findings indicate those mask manufacturers should consider safety and eco-friendliness over mask color and design.

Purpose: To grasp public opinion accurately, we conducted an opinion poll on beliefs and attitudes toward physician-assisted suicide (PAS). Methods: A randomized telephone survey ensuring a representative sample was conducted, 1,007 participants aged 18 years or older (response rate, 9.5%). Results: The main results are as follows: i) 61.1% of participants thought that the current social support system for terminally ill patients and their families is insufficient; ii) 60% of participants did not recognize the term "hospice and palliative care"; iii) 81.7% of participants would not like to receive life-sustaining treatment if there is no possibility of recovery; iv) 58.4% of participants would like to receive hospice and palliative care if they are diagnosed with a terminal illness; v) the priorities for dignified dying were preparing a support system to reduce the burden of care (28.6%), economic support including reduction of medical expenses (26.7%), expansion of hospice and palliative care services (25.4%), and legalization of PAS (13.6%); and vi) 58.3% of participants agreed that the expansion of hospice and palliative care should precede the legalization of PAS. Conclusion: Koreans currently want other efforts, including expansion of hospice and palliative care services, instead of the legalization of PAS.

Background: This study was aimed at investigating the perception of social network service (SNS) users regarding dental office visits and determining the proportion of dental SNS users among general SNS users. Methods: We surveyed 177 adults using SNSs. Dental SNS characteristics were classified into information provision, interaction, recency, reliability, and interest, and the recognition level of each area was surveyed on a 5-point scale. The total number of items was 17, including three information provision, three interaction, four recency, four reliability, and three interest items. Results: Among the five domains, the recognition level was the highest for reliability (3.51 points) and the lowest for interest (2.94 points). Among the 17 items, the recognition level was the highest for "Educational information provided by dental SNS is valuable" at 3.60 points, "Dental SNS educational video is useful for information sharing and dental knowledge improvement" at 3.53 points, and "The perceived educational information of dental SNS is reliable" at 3.51 points. Participants in their 20s and 30s had higher scores for being up-to-date (3.33 and 2.88 points, respectively) and reliability (3.59 and 3.09 points, respectively) than those in their 40s or older. The recognition level of all areas of dental SNS characteristics was significantly higher for experienced dental SNS users than for nonexperienced ones. Conclusions: The results of this study suggested that dental institutions should consider ways to utilize SNS for patient management and education and that dental SNS-related contents should contain educational and reliable information to help SNS users manage their oral health.

Purpose : The purpose of this study was to compare changes of salivary flow rate, salivary buffering capacity, and S. mutans after using a mouthwash containing essential oil or probiotics widely used as oral lactic acid bacteria in the oral environment. Methods : Fifty-three healthy adults aged 20 years or older voluntarily participated in this study after they were informed of the purpose of this study. Subjects were divided into a group treated with probiotics (L. reuteri) and a group treated with mouthwash containing essential oil. To evaluate changes in the oral environment, salivary flow rate, salivary buffering capacity, and S. mutans test were performed at baseline and 4 weeks later. Unstimulated and stimulated salivary flow samples were collected for 5 minutes and results were recorded in ml per minute. Salivary buffering capacity was divided into scores of 1 (low), 2 (moderate) and 3 (high) according to the color of the strip. The amount of S. mutans was classified as scores of 0, 1, 2, and 3 according to the decision table. Data collected in this study were analyzed at the 95 % significance level using the SPSS Version 23.0 program. Results : Both the unstimulated salivary flow rate and the stimulated salivary flow rate increased statistically after the intervention compared to those before intervention in the probiotics group. However, there was no statistically significant difference between the probiotics group and the mouthwash group. Salivary buffering capacity and S. mutans results showed no statistically significant differences between the probiotics group and the mouthwash group either. The salivary buffering capacity and the salivary flow rate showed a positive correlation. Conclusion : To improve the oral environment, such as salivary flow rate and salivary buffering capacity, an optimal product can be selected in consideration of individual preference and cost-effectiveness.

Purpose: Assessing physical strength and muscle mass is crucial, but many methods rely on specialized equipment, which can be challenging. In situations where a quick and straightforward test is needed, the sit-to-stand test (STST) proves useful. Although several studies have investigated STST and muscle mass separately, the actual correlation between these two factors has not been extensively researched. Hence, the objective was to comprehensively investigate the correlations between the different tests. Methods: The study participants consisted of 20 healthy young men in their 20s. In this study, measurements were taken for muscle mass, the five-times sit-to-stand test, the 30-second sit-to-stand test, and the 1-minute sit-to-stand test. The results of each test were analyzed using Pearson's correlation analysis. Results: Although no significant correlation was found between muscle mass and STST, interestingly, significant correlations were observed among the different types of STST. Conclusion: The STST is a rapid and straightforward test used to assess lower limb strength and balance ability in individuals. However, there is a dearth of research on STST conducted in domestic settings. Based on the findings of this study, further research is necessary to establish age- and gender-specific reference values for STST. This will allow its broader application, encompassing not only older adults and patients but also healthy individuals.

Background: Most developed countries are working to improve their universal health coverage systems. This study investigates regional disparities in unmet healthcare needs and their causes in South Korea. Additionally, it compares the unmet healthcare needs rate in South Korea with that of 33 European countries. Methods: The analysis incorporates information from 13,359 adults aged 19 or older, using data from the Korea Health Panel. The dependent variables encompass the experience of unmet healthcare needs and the three causes of occurrence: "burden of medical expenses," "time constraints," and "lack of care." The primary variable of interest is the region of residence, while control variables encompass 14 socio-demographic, health, and functional characteristics. Multivariable binary logistic regression analysis, accounting for the sampling design, is conducted. Results: The rate of unmet healthcare needs in Korea is 11.7% (95% confidence interval [CI], 11.0%-13.3%), which is approximately 30 times higher than that of Austria (0.4%). The causes of unmet healthcare needs, ranked in descending order, are "lack of care," "time constraints," and "burden of medical expenses." Predictive probabilities for experiencing unmet healthcare needs and each cause differ significantly between regions. For instance, the probability of experiencing unmet healthcare needs due to "lack of care" is approximately 10 times higher in Gangwon-do (13.5%; 95% CI, 13.0%-14.1%) than in Busan (1.3%; 95% CI, 1.3%-1.4%). The probability due to "burden of medical expenses" is approximately 14 times higher in Seoul (4.1%; 95% CI, 3.6%-4.6%) compared to Jeollanam-do (0.3%; 95% CI, 0.2%-0.4%). Conclusion: Amid rapid sociodemographic transitions, South Korea must make significant efforts to alleviate unmet healthcare needs and the associated regional disparities. To effectively achieve this, it is recommended that South Korea involves the National Assembly in healthcare policy-making, while maintaining a centralized financing model and delegating healthcare planning and implementation to regional authorities for their local residents-similar to the approaches of the United Kingdom and France.

Purpose: The purpose of this study was to analyze the association between single-person households & Beneficiary of National Basic Livelihood and recommendation on alcohol consumption, and counseling on drinking problems for adults 19 years of age or older. Methods: In this study, excluding missing values, the association between the single-person household & Beneficiary of National Basic Livelihood and recommendation to refrain drinking alcohol, counseling for drinking problems was analyzed by using the chi-squre test and logistic regression analysis. Results: In the case of non-single person households, compared to single-person households, the recommendation rate to refrain drinking alcohol was 1.519 OR (Odds Ratio [OR]: 1.159 , p-value <.0001). meanwhile, in the case of Beneficiary of National Basic Livelihood, the recommendation rate to refrain alcohol consumption was higher by 1.414 OR (OR: 1.414, p-value: 0.011), and the drinking problem counseling rate was also higher by 2.257 OR (OR: 2.257, p-value: 0.026) compared to non-beneficiary group. Discussion & Conclusion: Based on the 2016-2019 National Health and Nutrition Survey, this study investigated the associaiton between single households & Beneficiary of National Basic Livelihood and recommendations to refrain alcohol, and counseling on drinking problems. Compared to the Beneficiary of National Basic Livelihood group, single-person household group has recently been classified as a socially vulnerable group, but it is not applicable in the policy category. If policy and institutional measures for treatment are provided, it is expected that the problem of alcohol abuse can be reduced.

Objectives: This study examined the changes in dietary habits, the prevalence of chronic diseases, and mental health problems in the regional areas of the Republic of Korea before and after the COVID-19 pandemic to provide evidence of the status of regional health inequalities. Methods: This study analyzed Korean adults aged 19 or older who participated in the Korea Community Health Survey (n = 686,708) and Consumer Behavior Survey for Foods (n = 19,109) from 2018 to 2020. The participants were classified according to their residence area (Seoul metropolitan area, Metropolitan cities, Provinces); 2018-2019 were defined as before COVID-19, and 2020 as after COVID-19. The dietary behaviors, chronic diseases, and mental health problems were measured using a self-report questionnaire. Results: After COVID-19, the eating-out usage rate in the Seoul metropolitan area and Provinces decreased compared to before COVID-19 (P < 0.001), and when responding that they eat out, the frequency of eating out with household members in the Seoul metropolitan area increased (P = 0.024). The deliveries/takeout usage rate in the Provinces decreased after COVID-19 compared to before (P < 0.001). After COVID-19, the prevalence of obesity decreased in all regions (P < 0.001), and the prevalence of hypertension increased significantly in the Provinces (P = 0.015). The prevalence of diabetes mellitus increased continuously before and after COVID-19 in all regions (P < 0.002). High-risk subjective stress levels increased significantly in the Seoul metropolitan area (P < 0.001), and sleep duration significantly increased in all regions (P < 0.001). Major depressive disorder was reduced significantly in Metropolitan cities (P = 0.042) and Provinces (P < 0.001). Conclusions: After the COVID-19 pandemic, the prevalence of chronic diseases and mental health problems showed regional differences along with changes in dietary habits. It is necessary to reflect the regional differences in dietary habits in future policies resolving regional health inequalities.
