RESUMO
In this retrospective cohort study, we investigated: (1) The impact of comorbid chronic kidney disease (CKD) on postoperative mortality in patients with a hip fracture; (2) mortality variations by dialysis type, potentially indicating CKD stage; (3) the efficacy of different hip fracture surgical methods in reducing mortality for patients with CKD. This study included 25,760 patients from the Korean National Health Insurance Service-Senior cohort (2002-2019) who underwent hip fracture surgery. Participants were categorized as CKD and Non-CKD. Mortality rate was determined using a generalized linear model with a Poisson distribution. The effect size was presented as a hazard ratio (HR) through a Cox proportional-hazard model. During follow-up, we ascertained that 978 patients (3.8%) had CKD preoperatively. Compared to the Non-CKD group, the mortality risk (HR) in the CKD group was 2.17 times higher (95% confidence interval [CI], 1.99-2.37). In sensitivity analysis, the mortality risk of in patients who received peritoneal dialysis and hemodialysis was 6.21 (95% CI, 3.90-9.87) and 3.62 times (95% CI, 3.11-4.20) higher than that of patients who received conservative care. Mortality risk varied by surgical method: hip hemiarthroplasty (HR, 2.11; 95% CI, 1.86-2.40), open reduction and internal fixation (HR, 2.21; 95% CI, 1.94-2.51), total hip replacement (HR, 2.27; 95% CI, 1.60-3.24), and closed reduction and percutaneous fixation (HR, 3.08; 95% CI, 1.88-5.06). Older patients with CKD undergoing hip fracture surgery had elevated mortality risk, necessitating comprehensive pre- and postoperative assessments and management.

BACKGROUND: As income and health are closely related, retirement is considered undesirable for health. Many studies have shown the association between pension and health, but no research has considered the association between contribution-based public pensions or their types and health. OBJECTIVE: This study investigates the association between the type of contributory public pension and depressive symptoms among older adults. METHODS: We analyzed the data of 4541 older adults who participated in the South Korea Welfare Panel Study (2014-2020). Depressive symptoms were measured using the 11-item Center for Epidemiologic Studies Depression scale. Public pensions in South Korea are classified into specific corporate pensions and national pensions. For subgroup analyses, pensioners were categorized according to the amount of pension received and the proportion of public pension over gross income. Analyses using generalized estimating equations were conducted for longitudinal data. RESULTS: Individuals receiving public pension, regardless of the pension type, demonstrated significantly decreased depressive symptoms (national pension: ß=-.734; P<.001; specific corporate pension: ß=-.775; P=.02). For both pension types, the higher the amount of benefits, the lower were the depression scores. However, this association was absent for those who received the smaller amount among the specific corporate pensioners. In low-income households, the decrease in the depressive symptoms based on the amount of public pension benefits was greater (fourth quartile of national pension: ß=-1.472; P<.001; second and third quartiles of specific corporate pension: ß=-3.646; P<.001). CONCLUSIONS: Our study shows that contributory public pension is significantly associated with lower depressive symptoms, and this association is prominent in low-income households. Thus, contributory public pensions may be good income sources for improving the mental health of older adults after retirement.

BACKGROUND: As excessive caffeine intake may be associated with anxiety disorders, one of the most prevalent mental illnesses among adolescents globally, this study investigated the association between high caffeine consumption and anxiety in a nationally representative sample of South Korean adolescents. METHODS: 46,873 participants from the Korea Youth Risk Behavior Web-based Survey (KYRBS) 2022 were included. The Generalized Anxiety Disorder-7 (GAD-7) questionnaire was used to evaluate anxiety symptoms. Survey questions determined the number of times each participant consumed high-caffeine drinks per week. The chi-square test was used to investigate and compare the general characteristics of the study population, and a modified Poisson regression was used to analyze the relationship. RESULTS: Both male and female participants reporting excessive high-caffeine drink consumption exhibited higher anxiety levels (adjusted prevalence ratio [aPR]: 1.19, 95% confidence interval [CI]: 1.08-1.31 in males; aPR: 1.14, CI: 1.05-1.23 in females). This association remained statistically significant in subgroup analyses, particularly among high school students and those with a shorter sleep duration. The relationship between high-caffeine drink consumption and anxiety strengthened with increasing anxiety levels. Additionally, there was a dose-dependent relationship between the prevalence of anxiety and high-caffeine drinks. CONCLUSION: High caffeine consumption increases anxiety in South Korean adolescents. This association proved consistent regardless of sex or other socioeconomic factors.

BACKGROUND: The Korean government has implemented a comprehensive nursing care service system (CNS) to mitigate the stress faced by caregivers. OBJECTIVE: This study aimed to assess trends in the estimated average costs of private caregiving and determine the difference in costs between those using CNS and those not using it. DESIGN: A comparative interrupted time series analysis with a 2-year lag period verified total private caregiving cost trends; biannual differences in costs were evaluated based on using CNS. PARTICIPANTS: The main unit of analysis was episode. We extracted a total of 6418 episodes of hospitalization in acute care settings that included the use of caregiving services (formal, informal caregiving and CNS). METHODS: We conducted segmented regression to assess the impact of CNS on total private caregiving costs using data from 2012 to 2018, excluding the years 2015 and 2016 of the Korean Health Panel dataset. RESULTS: We presented that the immediate mean difference in total private caregiving costs between CNS users and non-users was -444.7 USD two years after the implementation of the CNS policy (95â¯% CI -714.5 to -174.5, p-value 0.001). Among individuals living in rural areas, two years after the implementation of the CNS policy, there was a significant immediate mean cost difference of -476.9 USD in total private caregiving costs between CNS users and non-users (p-value 0.011). Similarly, for episodes with a Charlson Comorbidity Index (CCI) score of 0 to 1, there was a substantial immediate mean cost difference in total private caregiving costs between CNS users and non-users, amounting to -399.9 USD two years after the CNS policy (p-value 0.008). CONCLUSIONS: This study evaluated the trend of total private caregiving costs between groups using and not using CNS. After two years of being covered by CNS health insurance, those who utilized CNS paid $433 less for their total private caregiving cost over a 6-month period, compared to those who did not use CNS. The adoption of CNS may be an effective system for relieving the financial burden on inpatients in need of private caregiving services. TWEETABLE ABSTRACT: Korean Comprehensive Nursing Service reduces private caregiving costs.

AIMS: Antidepressants are widely used by individuals with type 2 diabetes mellitus (T2DM). This study aimed to explore the correlation between antidepressant use, considering specific antidepressant subclasses or cumulative doses, and diabetic foot ulcer (DFU) risk. METHODS: This nested case-control study was conducted using a representative population-based Korean cohort database from 2002 to 2019. Participants with DFUs were matched with participants without DFUs based on age, sex, date of T2DM diagnosis, and follow-up duration. In total, 791 DFUs and 3900 controls were included. The association between antidepressant use or cumulative dose of each antidepressant subclass, DFU risk and amputation risk was examined using a conditional logistic regression model. RESULTS: Antidepressant ever-use was associated with an increased incidence of DFUs compared with non-use. Furthermore, an increase in DFU risk was evident with increasing cumulative antidepressant dosage, particularly among tricyclic antidepressant (TCA) ever-users and selective serotonin reuptake inhibitors (SSRIs) ever-users. Additionally, antidepressant ever-users displayed a higher risk of DFUs requiring amputation, which was consistently observed when the cumulative dosages of overall antidepressants and TCAs were considered. CONCLUSION: Caution is advised when administering TCAs and SSRIs in antidepressant-naïve T2DM patients to reduce DFU and the consequent amputation risk.

Internet use disorder (IUD) is an emerging social and mental health concern. This study aimed to analyze the relative risk of IUD in late childhood among children whose mothers experienced peripartum depressive symptoms. This study included 762 participants (397 boys and 365 girls) and was conducted in 2017 (aged 9) and 2019 (aged 11). We analyzed the adjusted relative risk of being at high risk for IUD based on whether the mother experienced depressive symptoms during pregnancy or one month after delivery. We also considered the persistence of depressed mood for 4 months after delivery and the severity of peripartum depressive symptoms. From 2017, 20.7% of boys and 14.0% of girls were at high risk of developing IUD. Compared to the non-peripartum depressive group, girls whose mothers experienced peripartum depressive symptoms and those that persisted for 4 months were 1.084 and 1.124 times more likely to be at high risk of IUD (95% confidence interval = 1.005-1.170 and 1.013-1.248), respectively. There were no statistically significant differences among boys. Peripartum depressed mood could be one of risk factors of IUD. IUD needs to be monitored in children whose mothers experienced peripartum depressive symptoms.

Cryptococcus neoformans infections occur most frequently in immunocompromised patients. Here, we report a case of cryptococcal meningitis in a previously immunocompetent 78-year-old female patient after treatment of COVID-19. Underlying diseases included hypertension, hyperlipidemia, and diabetes. The patient was critically ill and was treated with remdesivir, baricitinib, and dexamethasone. During hospitalization, her mental state changed, and C. neoformans was detected in the cerebrospinal fluid. She died despite receiving antifungal treatment. Treatment of COVID-19 may be a predisposing factor for C. neoformans infection. There is a need for concern and countermeasures for opportunistic fungal infections that may accompany COVID-19.

BACKGROUND: The Korean government implemented financial incentives to enhance infection prevention and management within general hospital settings. This study aimed to evaluate the impact of infection control compensation on antibiotic usage using a controlled interrupted time series analysis. METHODS: The main unit of analysis was 270,901 inpatient episodes extracted from the Korean National Health Insurance Service Cohort Database from 2013 to 2019. The 96-month period was examined before and after the intervention, which was set to September 1, 2017, by applying a 1-year lag time after the incentive was introduced. Segmented regression was used to estimate the effects of interventions in a controlled interrupted time series. Hospitals that received nationwide financial incentives for infection prevention and management were included in the analysis. The study's primary outcome was the use of antibiotics based on the WHO Access, Watch, and Reserve (AWaRe) classification of antibiotics, and the secondary outcome was the number of days of antibiotic use as days of therapy (DOTs) per patient day (PD). RESULTS: The probability of overall antibiotic use decreased between incentivized and unincentivized hospitals (odds ratio [OR], 0.922; 95% confidence interval [CI], 0.859-1.000). The difference in level change in the use of third-generation cephalosporins (OR,0.894; 95% CI, 0.817-0.977) and carbapenem (OR,0.790; 95% CI, 0.630-0.992) was significantly reduced between incentivized and unincentivized hospitals. The difference in slope change on DOTs/PD of glycopeptides was -â¯0.005 DOT/PDs, and that of carbapenem was -â¯0.003 between incentivized and unincentivized hospitals. CONCLUSION: We observed that incentives for infection prevention and management have had a positive impact on some aspects of antibiotic usage. A partial decrease was observed in antibiotic use, accompanied by a modest reduction in DOTs/PD, particularly for antibiotics aimed at addressing multidrug-resistant pathogens. Further investigation is necessary to establish evidence for extending these incentives.

PURPOSE: To develop an ethical and cultural infrastructure for Life-Sustaining Treatment (LST) plan, it is crucial to carefully analyze its impact and ensure that healthcare utilization is maintained at an appropriate level, avoiding excessive medical interventions. This study aims to investigate the effects of LST decisions on both healthcare expenditure and utilization. METHODS: This cohort study utilized claims data from the National Health Insurance Service, encompassing all medical claims in South Korea. We included individuals who had planned to withdraw or withhold their LST between January and December 2018, identified by claim code IA71, IA72, IA73. We followed a total of 28,295 participants with documented LST plan who were deceased by June 2020. Participants were categorized into LST withdrawal / withholding and LST continuation groups. The dependent variables were healthcare expenditure and utilization. We construct a generalized linear model to analyze the association between these variables. RESULTS: Out of the 28,295 participants, 24,436 (86.4%) chose to withdraw or withhold LST, while the rest opted for its continuation. Compared to the LST continuation group, those who chose to withdraw or withhold LST had 0.91 times lower odds for total cost. Additionally, they experienced 0.91 times fewer hospitalization days and 0.92 times fewer outpatient visits than those in the LST continuation group. CONCLUSION: Healthcare expenditure and utilization deceased among those choosing to withdraw or withhold LST compared to those continuing it. These findings underscore the significance of patients actively participating in decision regarding their treatment to ensure appropriate levels of medical intervention for LST. Furthermore, they emphasize the critical role of proper education and the establishment of a cultural framework for LST plans.

Post-traumatic stress disorder (PTSD) is associated with the development of dementia; however, the association of dementia risk with overall stress-related disorders is less known. This study investigated the association between stress-related disorders and the risk of dementia in a Korean nationwide sample cohort. The data analyzed in this study were acquired from the Korean National Health Insurance Service National Sample Cohort between 2002 and 2013. Using a 1:3 propensity score matching, 8906 patients with stress-related disorders and 26,718 control participants were included in the analysis. Patients with stress-related disorders had a higher risk of developing dementia after adjusting for covariates (hazard ratio [HR] = 1.15; 95% confidence interval [CI] 1.01-1.30) than control participants. Patients with PTSD showed the highest risk of increase (HR = 1.78) than those with other types of stress-related disorders. Patients with stress-related disorders showed the highest and significantly increased risk for Alzheimer's dementia (HR = 1.22, 95% CI 1.04-1.56). These results indicated an association between a history of stress-related disorders and the risk of dementia in the South Korean population. Further research investigating the causal mechanisms is needed.

Background: In Republic of Korea, household debt has increased recently among young adults, especially during the COVID-19 pandemic. Household debt may potentially lead to numerous outcomes including alcohol use disorder (AUD). The aim of this study was to investigate the relationship between a change in indebtedness and the risk of developing AUD. Methods: A total of 5,091 participants (2,720 men and 2,371 women) were included during a 4-year study period. Indebtedness was divided into four groups: no debt a year ago and at present (group 1), paying off a year's debt (group 2), newly incurred current debt after a year when there was no debt (group 3), and indebtedness a year ago and at present (group 4). Groups 2, 3, and 4 were also divided into subgroups based on debt characteristics. AUD risk was evaluated by the CAGE scale, and a score of 2 or higher was defined as AUD high risk. Several time-varying socioeconomic and health-related characteristics were adjusted. Results: Participants who indicated indebtedness at present (groups 3 and 4) were more likely to be AUD high-risk compared to group 1 in both genders (men: adjusted relative risk [aRR] = 1.031, 95% CI [1.014-1.049] in group 3, aRR = 1.028, 95% CI [1.007-1.050] in group 4; women: aRR = 1.039, 95% CI [1.016-1.163] in group 3, aRR = 1.028, 95% CI [1.007-1.050] in group 4). Even paid-off debt affected the risk of AUD among female participants (aRR = 1.018, 95% CI [1.001-1.034] in group 2). Women whose amount of debt increased for 1 year were more likely to be AUD high-risk compared to group 1. Women showed higher aRR than men for increasing CAGE scores by one unit in all debt subgroups. Conclusion: Our research demonstrated a possible link between indebtedness and a heightened risk of AUD. These results underscore the importance of implementing targeted screening and interventions for AUD, particularly among young women who are facing mounting levels of debt.
RESUMO
BACKGROUND: Caregiving services often place a financial burden on individuals and households that use inpatient medical services. Consequently, this study aimed to examine the association between the type of caregiver and catastrophic health expenditure among households utilizing inpatient medical services. METHODS: Data were extracted from the Korea Health Panel Survey conducted in 2019. This study included 1126 households that used inpatient medical and caregiver services. These households were classified into three groups: formal caregivers, comprehensive nursing services, and informal caregivers. Multiple logistic regression was used to analyze the association between caregiver type and catastrophic health expenditure (CHE). RESULTS: Households receiving formal caregiving had an increased likelihood of CHE at threshold levels of 40% compared to those who received care from family (formal caregiver: OR 3.11; CI 1.63-5.92). Compared to those who received formal caregiving, households using comprehensive nursing services (CNS) had a decreased likelihood of CHE (CNS: OR, 0.35; CI 0.15-0.82). In addition, considering the economic value associated with informal care, there was no significant relationship between households received formal caregiving and informal caregiving. CONCLUSION: This study found that the association with CHE differed based on the type of caregiving used by each household. Households using formal care had a risk of developing CHE. Households using CNSs were likely to have a decreased association with CHE, compared to households using informal and formal caregivers. These findings highlight the need to expand policies to mitigate the burden on caregivers for households forced to use formal caregivers.

BACKGROUND: The number of industrially injured workers (IIW) is increasing in Korea. However, little research has been conducted on whether first aid is performed at industrial sites or on the association between first aid for industrial injuries and the prognosis of IIW, including healthcare utilization. METHODS: A total of 3,092 participants (2,562 males and 530 females) were analyzed during the 4-year study period, which contributed to 11,167 observations. Healthcare utilization was evaluated based on the number of outpatient visits, hospitalizations, and duration of hospitalization using a generalized estimating equation Poisson regression. Several time-varying socioeconomic characteristics and information about the injury were adjusted, and transfer time to the medical institutions was also considered. RESULTS: During 4-year after the termination of medical treatment, participants who had not receive first aid visited outpatient clinics 15.243 times per year, and those who had visited 13.928 times per year, which is 16.16% less (adjusted relative risk [aRR]: 0.838, 95% CI = 0.740-0.950). Participants who had received on-site first aid with less than a 0.5-hour transfer time to the medical institutions visited outpatient clinics 14.87% less per year than those who had not received first aid (aRR: 0.851, 95% CI = 0.750-0.966). CONCLUSION: To reduce the long-term outpatient utilization rate for IIW after medical treatment, on-site first aid must be provided in a timely manner. Employee education and first aid training are also necessary.
RESUMO
BACKGROUND: Gout incidence is increasing worldwide; appropriate management of serum uric acid levels and a healthy lifestyle may help its prevention. The popularity of electronic cigarettes and the resultant emergence of dual smokers is increasing. Despite many studies on the effects of various health behaviors on serum uric acid levels, the association between smoking and serum uric acid levels remains controversial. This study aimed to investigate the association between smoking and serum uric acid levels. METHODS: In this study, total sample of 27,013 participants (11,924 men and 15,089 women) were analyzed. This study used data from the Korea National Health and Nutrition Examination Survey (2016-2020) and grouped adults into dual smokers, single smokers, ex-smokers, and non-smokers. Multiple logistic regression analyses were performed to investigate the association between smoking behavior and serum uric acid levels. RESULTS: Compared to male non-smokers, male dual smokers had significantly higher serum uric acid level (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.08-1.88). In female, serum uric acid level was higher among single smokers than non-smokers (OR, 1.68; 95% CI, 1.25-2.25). Higher serum uric acid levels were more likely to be present in male dual smokers with a > 20 pack-year smoking habit (OR, 1.84; 95% CI, 1.06-3.18). CONCLUSION: Dual smoking may contribute to high serum uric acid levels in adults. Thus, serum uric acid levels should be properly managed through smoking cessation.

BACKGROUND: Chronic kidney disease (CKD) is a significant health care burden, with a worldwide prevalence of approximately 11%. The general population spends over 50% of the awake time sedentary activities. However, to the best of our knowledge, no study has evaluated the association between sedentary time and CKD, with a focus on both kidney damage and kidney function, in the South Korean population. Accordingly, the present study aimed to address this gap in the knowledge. METHOD: We used data from the 8th Korea National Health and Nutrition Examination Survey. The analysis included 9,534 participants, especially excluded those who had been diagnosed with kidney disease or who were currently undergoing treatment. Sedentary behavior was self-reported by the participants. An estimated glomerular filtration rate (eGFR) and/or albuminuria were used as measures for detection of CKD according to the guidelines of the Kidney Disease Improving Global Outcomes. We analyzed the data using multiple logistic regression. RESULTS: Among the women, the risk of CKD was significantly greater among those who sat for ≥ 12 h/d relative to those who sat for < 6 h/d, after adjusting for physical activity and other covariates (odds ratio [OR]: 1.45, 95% confidence interval [CI]: 1.01-2.06). Similarly, among those who sat over 12 h/d, those who engaged in low levels of physical activity had a higher risk of CKD than those who engaged in high levels of activity (OR: 1.65, 95% CI: 1.04-2.61). No statistically significant results were found for men. CONCLUSION: Excessive sedentary behavior was associated with an increased risk of CKD, especially albuminuria, regardless of the level of physical activity, only in women. These findings emphasize the importance of avoiding excessive sitting for a long time and increasing overall physical activity levels.

Background: A psychiatric interview is one of the important procedures in diagnosing psychiatric disorders. Through this interview, psychiatrists listen to the patient's medical history and major complaints, check their emotional state, and obtain clues for clinical diagnosis. Although there have been attempts to diagnose a specific mental disorder from a short doctor-patient conversation, there has been no attempt to classify the patient's emotional state based on the text scripts from a formal interview of more than 30 min and use it to diagnose depression. This study aimed to utilize the existing machine learning algorithm in diagnosing depression using the transcripts of one-on-one interviews between psychiatrists and depressed patients. Methods: Seventy-seven clinical patients [with depression (n = 60); without depression (n = 17)] with a prior psychiatric diagnosis history participated in this study. The study was conducted with 24 male and 53 female subjects with the mean age of 33.8 (± 3.0). Psychiatrists conducted a conversational interview with each patient that lasted at least 30 min. All interviews with the subjects between August 2021 and November 2022 were recorded and transcribed into text scripts, and a text emotion recognition module was used to indicate the subject's representative emotions of each sentence. A machine learning algorithm discriminates patients with depression and those without depression based on text scripts. Results: A machine learning model classified text scripts from depressive patients with non-depressive ones with an acceptable accuracy rate (AUC of 0.85). The distribution of emotions (surprise, fear, anger, love, sadness, disgust, neutral, and happiness) was significantly different between patients with depression and those without depression (p < 0.001), and the most contributing emotion in classifying the two groups was disgust (p < 0.001). Conclusion: This is a qualitative and retrospective study to develop a tool to detect depression against patients without depression based on the text scripts of psychiatric interview, suggesting a novel and practical approach to understand the emotional characteristics of depression patients and to use them to detect the diagnosis of depression based on machine learning methods. This model could assist psychiatrists in clinical settings who conduct routine conversations with patients using text transcripts of the interviews.
RESUMO
BACKGROUND: Amidst rapid population aging, South Korea enacted the Well-dying Act, late among advanced countries, but public opinion on the act is not still clear. Against this background, this study aims to: 1) investigate factors affecting elderly individuals' attitude toward life-sustaining treatment, and 2) examine whether attitude toward life-sustaining treatment is related to their perceived life satisfaction. METHODS: Data from the 2020 Survey of Living Conditions and Welfare Needs of Korean Older Persons were used. There were 9,916 participants (3,971 males; 5,945 females). We used multivariable-adjusted Poisson regression models with robust variance to examine the association between perceived life satisfaction and attitude toward life-sustaining treatment and calculate prevalence ratios (PR) and 95% confidence intervals (CI). RESULTS: After adjusting potential confounders, the probabilities that the elderly who were dissatisfied with their current life would favor life-sustaining treatment were 1.52 times (95% CI: 1.15-1.64) and 1.28 times (95% CI: 1.09-1.51) higher for men and women, respectively, than the elderly who were satisfied. In addition, attitudes in favor of life-sustaining treatment were observed prominently among the elderly with long schooling years or high household income, when they were dissatisfied with their life. CONCLUSIONS: Our results suggested that for the elderly, life satisfaction is an important factor influencing how they exercise their autonomy and rights regarding dying well and receiving life-sustaining treatment. It is necessary to introduce interventions that would enhance the life satisfaction of the elderly and terminally ill patients and enable them to make their own decisions according to the values of life.

BACKGROUND: The symptoms and outcomes of depressed mood are considered severe social issues among Korean adolescents. However, it is difficult to detect depressed mood and evaluate the factors associated with suicide among such individuals. Identifying the risk factors of depressed mood would allow for improved perspectives for interventions. Therefore, in this study, we investigated the association between sedentary behavior and the prevalence of depressed mood. METHODS: From 2014 to 2020, the Korea Youth Risk Behavior Survey (KYRBS), which is a web-based self-report survey, was used for analysis. A total of 366,405 individuals participated in this study. Sedentary behavior was divided into 3 groups based on the duration of sedentary behavior: low sedentary time group (LS, 25 percentile), middle sedentary time group (MS, from 25 to 75 percentile, reference), and high sedentary time group (HS, above 75 percentile). Further, sedentary behavior is divided into 4 subgroups based on weekdays or weekends and owing to studying or non-studying. The chi-square test and multivariate logistic regression were used in this study. RESULTS: Compared to the MS, which is the reference, male participants in both the LS and HS had experienced depressed mood (adjusted odds ratio (OR): 1.035, 95% CI = 1.003-1.068 in the LS, adjusted OR: 1.091, CI = 1.055-1.129 in the HS). Among females, only the HS was statistically significant (adjusted OR: 1.039, 95% CI = 1.011-1.069 in HS). Korean adolescents with longer sedentary durations during weekdays regardless of the cause of sedentary behavior are positively associated with depressed mood with suicidality in the HS for both genders. CONCLUSION: This study found a positive association between the prevalence of depressed mood and sedentary behavior, and it focused on the cause and timing.

Depression in older adults is a global socioeconomic burden. Identifying factors, such as physical activity or exercise that can help prevent depression is important. We aimed to investigate the relationship between changes in handgrip strength and the presence of depression using longitudinal, nationwide data of older Korean adults. Data from the Korean Longitudinal Study of Aging were used in this study. A total of 6783 participants who had undergone a handgrip strength test and completed the short-form Center for Epidemiologic Studies Depression Scale (CESD-10-D) questionnaire from 2006 to 2018 were included. General estimating equations were used to assess the temporal effect of the changes in handgrip strength on depression. A decrease in handgrip strength was associated with high CESD-10-D scores (ß = 0.1889 in men, ß = 0.1552 in women). As a continuous variable, handgrip strength was negatively correlated with CESD-10-D scores(ß = - 0.0166 in men, ß = - 0.0196 in women). Changes in the handgrip strength were associated with depressive symptoms in our longitudinal study. Those who experienced a decrease in handgrip strength had severe depressive symptoms compared to those with unchanged or increased handgrip strength. These findings can be used to guide general health policies for the prevention of depression.

We investigated whether dining with companions is correlated with the alleviation of depression and differs by sex among Korean adults. We used 4-year data from the 2014, 2016, 2018, and 2020 Korea National Health and Nutrition Examination Survey. We surveyed 11,055 participants (4699 men, 6356 women) using the Patient Health Questionnaire-9 to measure their depression scores. We evaluated participants' meal companionship status by asking whether they had usually dined with companions for breakfast, lunch, or dinner during the past year. Statistical analysis was performed using chi-square tests and multivariate/multinomial logistic regression. We found depression to be less prevalent among participants who dined with companions at least once a day (adjusted OR: 0.26, 95% CI: 0.15-0.45, men; adjusted OR: 0.50, 95% CI: 0.34-0.74, women). In the moderate depression subgroup, participants who dined with companions at least once a day showed lower OR (adjusted OR: 0.28, 95% CI: 0.16-0.50, men; adjusted OR: 0.50, 95% CI: 0.32-0.76, women). Among participants who dined together, men's severe depression dramatically decreased (adjusted OR: 0.05, 95% CI: 0.01-0.31). Thus, we found an association between dining with companions and the prevalence of depression among Korean adults. Dining with companions compared with dining alone signified a lower depression rate, especially among men. This study can provide an initiative to further analyze psychological and physiological effects of dining together and be applied to practical fields as education and societal campaigns.
