Heightened vigilance and its associations with suicidal ideation and suicide attempt among 285 Korean transgender and nonbinary adults: Effect modification by connectedness to the LGBTQ+ community.

INTRODUCTION: Anti-transgender stigma presents threats of discrimination to transgender and nonbinary (TGNB) individuals, prompting them to stay vigilant. Using a longitudinal data of 285 South Korean TGNB adults, we examined vigilance and its associations with suicidal ideation and suicide attempt and explored the protective role of connectedness to the lesbian, gay, bisexual, transgender, and queer (LGBTQ+) community. METHODS: Data were collected in October 2021 (baseline) and October 2022 (follow-up). Vigilance was measured using the 4-item Heightened Vigilance Scale at baseline. At follow-up, 12-month suicidal ideation and suicide attempt, and connectedness to the LGBTQ+ community were measured. RESULTS: Having heightened levels of vigilance was associated with increased prevalence of suicidal ideation (Prevalence Ratio [PR]: 1.33, 95% Confidence Interval [CI]: 1.09-1.62) and suicide attempt (PR: 2.18, 95% CI: 1.23-3.86), after adjusting for covariates including anti-transgender discrimination experiences and lifetime suicidality at baseline. When stratified by connectedness to the LGBTQ+ community, the associations between vigilance and suicidality remained statistically significant among those with low connectedness whereas no statistically significant association was observed among those with high connectedness. CONCLUSION: The study provides empirical evidence for policies and interventions that ensure safety of TGNB individuals from discrimination and promote connectedness to the LGBTQ+ community to reduce the suicide risk among TGNB individuals.

People-Oriented Culture and its association with burnout, depressive symptoms, and sleep problems during COVID-19 pandemic among EMS providers in Korea.

OBJECTIVE: This study examined how perceived people-oriented culture (POC) was associated with burnout, depressive symptoms, and sleep problems during the COVID-19 pandemic among emergency medical service (EMS) providers in Korea. METHODS: We conducted a cross-sectional survey among 693 EMS providers in 2021. RESULTS: Overall, 60% reported burnout and around 25% had depressive symptoms. Prevalence of poor sleep quality, unrestful sleep, and sleep disturbance were 46.5%, 58.2%, and 52.2%, respectively. Compared to high POC group, higher prevalence of depressive symptoms was observed among medium (PR: 1.57, 95% CI: 1.06, 2.32) and low (PR: 2.70, 95% CI: 1.92, 3.79) POC group. Similar trends were observed in the analysis of burnout and sleep problems. CONCLUSIONS: Our findings underscore that low POC could play a critical role in worsening burnout, depressive symptoms, and sleep problems among EMS providers.

Ethnic discrimination, asking for fair treatment, and poor self-rated health: a gender stratified analysis of 13,443 Korean Chinese waged workers in South Korea.

BACKGROUND: In South Korea, Korean Chinese workers experience ethnic discrimination although they share physical similarities and ethnic heritage with native-born Koreans. This study aimed to examine whether perceived ethnic discrimination is associated with poor self-rated health and whether the association differs by gender among Korean Chinese waged workers in South Korea. METHODS: We conducted a pooled cross-sectional analysis using data of 13,443 Korean Chinese waged workers from the Survey on Immigrants' Living Conditions and Labor Force conducted in 2018, 2020, and 2022. Based on perceived ethnic discrimination, asking for fair treatment, and subsequent situational improvement, respondents were classified into the following four groups: "Not experienced," "Experienced, not asked for fair treatment," "Experienced, asked for fair treatment, not improved," and "Experienced, asked for fair treatment, improved." Poor self-rated health was assessed using a single question "How is your current overall health?" We applied logistic regression to examine the association between perceived ethnic discrimination and poor self-rated health, with gender-stratified analyses. RESULTS: We found an association between ethnic discrimination and poor self-rated health among Korean Chinese waged workers. In the gender-stratified analysis, the "Experienced, not asked for fair treatment" group was more likely to report poor self-rated health compared to the "Not experienced" group, regardless of gender. However, gender differences were observed in the group stratified by situational improvements. For male workers, no statistically significant association was found in the "Experienced, asked for fair treatment, improved" group with poor self-rated health (odd ratios: 0.87, 95% confidence intervals: 0.30-2.53). Conversely, among female workers, a statistically significant association was observed (odd ratios: 2.63, 95% confidence intervals: 1.29-5.38). CONCLUSIONS: This study is the first to find an association between perceived ethnic discrimination and poor self-rated health, along with gender differences in the association between situational improvements after asking for fair treatment and poor self-rated health among Korean Chinese waged workers in South Korea.

Does discrimination prevent transgender and gender diverse people from seeking healthcare?: A nationwide cohort study in South Korea.

Introduction: Using Asia's first nationwide cohort dataset, this study aimed to assess the prevalence of anti-transgender discrimination and healthcare avoidance and delay (HAD) and examine their associations among transgender and gender diverse (TGD) adults in South Korea. Methods: We analyzed a two-wave (2020-2021) longitudinal dataset of 190 Korean TGD adults. Anti-transgender discrimination were classified accordingly: experienced at (1) neither wave, (2) baseline (2020) only, (3) follow-up (2021) only, and (4) both waves. We also asked about HAD in the past 12 months at follow-up for both transition-related and non-transition-related healthcare services. Multivariate modified Poisson regression was used to examine the associations between anti-transgender discrimination and HAD. Results: Of 190 participants, 102 (53.7%) experienced anti-transgender discrimination at both waves, and 130 (68.4%) reported HAD at follow-up. Compared to those without any experiences of anti-transgender discrimination, those who experienced it in both waves had a 1.78-times (95% CI: 1.21-2.63) higher prevalence of non-transition-related HAD, but not among those who experienced it in either wave. In contrast, anti-transgender discrimination was not associated with transition-related HAD. Conclusion: In order to enhance healthcare access for transgender and gender diverse (TGD) individuals, it is necessary to implement interventions, such as anti-discrimination laws, that protect them from discrimination.

Change in employment status and its causal effect on suicidal ideation and depressive symptoms: A marginal structural model with machine learning algorithms.

OBJECTIVE: This study aimed to assess the causal effect of a change in employment status on suicidal ideation and depressive symptoms by applying marginal structural models (MSM) with machine-learning (ML) algorithms. METHODS: We analyzed data from the 8-15th waves (2013-2020) of the Korean Welfare Panel Study, a nationally representative longitudinal dataset. Our analysis included 13 294 observations from 3621 participants who had standard employment at baseline (2013-2019). Based on employment status at follow-up year (2014-2020), respondents were classified into two groups: (i) maintained standard employment (reference group), (ii) changed to non-standard employment. Suicidal ideation during the past year and depressive symptoms during the past week were assessed through self-report questionnaire. To apply the ML algorithms to the MSM, we conducted eight ML algorithms to build the propensity score indicating a change in employment status. Then, we applied the MSM to examine the causal effect by using inverse probability weights calculated based on the propensity score from ML algorithms. RESULTS: The random forest algorithm performed best among all algorithms, showing the highest area under the curve 0.702, 95% confidence interval (CI) 0.686-0.718. In the MSM with the random forest algorithm, workers who changed from standard to non-standard employment were 2.07 times more likely to report suicidal ideation compared to those who maintained standard employment (95% CI 1.16-3.70). A similar trend was observed in the analysis of depressive symptoms. CONCLUSIONS: This study found that a change in employment status could lead to a higher risk of suicidal ideation and depressive symptoms.

Female workers with long working hours are more likely to have depressive symptoms when having family-to-work conflict.

PURPOSE: Workers' health can be influenced by risk factors from their family environments as well as their work environments. This paper sought to examine how the association between long working hours and depressive symptoms differs based on the level of FWC after being stratified by worker's gender. METHODS: We used the dataset of 20,384 full-time wage workers from the sixth Korean Working Conditions Survey (2020). Long working hours were defined as working 52 h or more per week. FWC was measured using a 2-item questionnaire, and depressive symptoms were measured using the WHO-5 well-being index. Applying modified Poisson regression, we evaluated how the association between long working hours and depressive symptoms differs by the level of FWC male and female workers separately. RESULTS: In the analysis of the female workers, long working hours were associated with depressive symptoms in the high FWC group (PR 1.35, 95% CI 1.17, 1.55) after adjusting for potential confounders whereas no association was observed in the low FWC group. Among the male workers, a statistically significant association was observed in both high FWC (PR 1.22, 95% CI 1.07, 1.38) and low FWC (PR 1.28, 95% CI 1.12, 1.47) groups. CONCLUSION: FWC may act as a workplace stressor that potentially amplifies the health impact of long working hours among female workers.

Situational Avoidance and Its Association with Mental Health Among Transgender Adults in South Korea: A Nationwide Cohort Study.

Purpose: In fear of discrimination or unwanted disclosure of their transgender identity, transgender and nonbinary (TGNB) people may commonly avoid daily activities. We assessed the prevalence of situational avoidance among TGNB people and examined its associations with mental health outcomes. Methods: We analyzed data from a longitudinal survey conducted at baseline (2020) and follow-up (2021) among 268 TGNB people in South Korea. Situational avoidance due to transgender identity within the past 12 months was assessed based on 12 kinds of daily activities (e.g., public bathroom use, job applications, and hospital visits). Past-week depressive symptoms and past 2-week anxiety symptoms were measured with the Center for Epidemiologic Studies-Depression Scale and General Anxiety Disorder Scale, respectively. Results: Of 268 participants, 135 (50.4%) have ever avoided daily activities. The most frequently reported situational avoidance was public bathroom use (32.1%), followed by job applications (24.3%) and hospital visits (12.3%). After adjusting for confounders including baseline depressive symptoms and experience of anti-transgender discrimination, participants with any situational avoidance experience were 1.30 times (95% confidence intervals [CI] = 1.01-1.69) more likely to have anxiety symptoms compared with those without situational avoidance experience. In particular, participants who avoided three or more kinds of daily activities were 1.40 times (95% CI = 1.02-1.93) more likely to have anxiety symptoms than those without any experience of situational avoidance. No association was observed with depressive symptoms. Conclusion: Multilateral interventions including anti-discrimination law enactment are necessary to reduce transphobia and provide support for TGNB people in Korea, thus reducing their fear of participating in daily activities and promoting their mental well-being.

Associations between discrimination experiences and symptoms of depression and anxiety among transgender adults: a nationwide cohort study of 269 transgender adults in South Korea.

PURPOSE: Recently, there has been an increase in awareness of social stigma and mental health issues experienced by transgender individuals in South Korea. To provide quantitative evidence, we conducted a nationwide cohort study of transgender adults, first of its kind in Asia. The aim of the study is to assess the prevalence of depressive and anxiety symptoms and examine their associations with discrimination experiences among transgender adults. METHODS: We conducted a two-wave longitudinal survey of 269 Korean transgender adults, where the baseline was collected in October 2020 and the follow-up in October 2021. Experiences of discrimination in the past 12 months at follow-up were categorized accordingly: those who experienced (1) none, (2) only anti-transgender discrimination, (3) only other types of discrimination, and (4) both anti-transgender and other types of discrimination. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression scale at both waves and anxiety symptoms were measured using the Generalized Anxiety Disorder 7 only at follow-up. We used modified Poisson regression to examine the association between experiences of discrimination and mental health outcomes at follow-up and adjusted for sociodemographic characteristics and baseline depressive symptoms. RESULTS: A total of 63.9% had depressive symptoms and 47.2% had anxiety symptoms. Participants who experienced both anti-transgender and other types of discrimination had 1.38-times (95% CI 1.06-1.81) and 1.77-times (95% CI 1.16-2.70) higher prevalence of depressive and anxiety symptoms, respectively, compared to those without any experiences of discrimination. CONCLUSIONS: Interventions to lessen discrimination towards transgender individuals are needed for the promotion of mental health among transgender individuals.

Transgender-specific COVID-19-related stressors and their association with depressive symptoms among transgender adults: A nationwide cross-sectional survey in South Korea.

Introduction: COVID-19 has disproportionately impacted marginalized groups, including transgender populations, reproducing and exacerbating inequalities and vulnerabilities that existed in those groups prior to the pandemic. This study aimed to assess the prevalence of transgender-specific COVID-19-related stressors and their association with depressive symptoms among South Korean transgender adults. Methods: We conducted a nationwide cross-sectional study of 564 South Korean transgender adults (trans women, trans men, and nonbinary people) from October 7 to October 31, 2020. We measured four transgender-specific COVID-19-related stressors as follows: (A) had difficulty receiving gender-affirming healthcare due to economic hardship related to COVID-19, (B) had difficulty receiving gender-affirming healthcare due to limited access to hospitals under the COVID-19 situation, (C) had difficulty purchasing a public face mask due to gender information on an identification card, and (D) avoided getting a COVID-19 test in fear of unfair treatment and dirty looks due to gender identity, despite having COVID-19 symptoms. Past-week depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale. Results: Of the total participants, 30.7% experienced any of the four transgender-specific COVID-19-related stressors, and 70.2% were classified as having depressive symptoms during the past week. We found statistically significant associations with depressive symptoms among participants who reported that they had difficulty receiving gender-affirming healthcare due to either economic hardship (adjusted prevalence ratio [aPR] = 1.20, 95% Confidence Interval [CI] = 1.05-1.37) or limited access to hospitals (aPR = 1.15, 95% CI = 1.00-1.32), respectively. Furthermore, those who had two or more of the four transgender-specific COVID-19-related stressors were 1.21 times (95% CI = 1.05-1.40) more likely to report depressive symptoms, compared to those who did not report any stressor. Conclusion: Transgender-specific COVID-19-related stressors may negatively influence depressive symptoms among South Korean transgender adults. Given these findings, transgender-inclusive interventions should be implemented at the policy level during the COVID-19 pandemic in South Korea.

Gender Identity Change Efforts Are Associated with Depression, Panic Disorder, and Suicide Attempts in South Korean Transgender Adults.

Purpose: Gender identity change efforts (GICEs), sometimes referred to as "conversion therapy," are considered pseudoscientific and unethical practices that are not supported by the existing scientific literature. However, a substantial portion of transgender people face such practices during their lives. We assessed lifetime exposure to GICEs and its associations with mental health indicators among transgender adults in South Korea. Methods: We analyzed a nationwide cross-sectional survey of 566 Korean transgender adults conducted in October 2020. Lifetime exposure to GICEs was classified as follows: "never had GICE-related experiences," "received a referral, but did not undergo GICEs," and "undergone GICEs." We assessed mental health indicators, including past-week depressive symptoms; medical diagnosis or treatment of depression and panic disorder; and past 12-month suicidal ideation, suicide attempts, and self-harm. Results: Of the total participants, 12.2% had "received a referral, but did not undergo GICEs," and 11.5% had "undergone GICEs." Compared with those who had "never had GICE-related experiences," participants who had "undergone GICEs" showed significantly higher prevalence of depression (adjusted prevalence ratio [aPR]=1.34, 95% confidence interval [CI]=1.11-1.61), panic disorder (aPR=2.52, 95% CI=1.75-3.64), and suicide attempts (aPR=1.73, 95% CI=1.10-2.72). However, we did not find significant associations between having "received a referral, but did not undergo GICEs" and mental health indicators. Conclusion: Given our findings suggest that lifetime exposure to GICEs may harm transgender adults' mental health, legal restrictions should be imposed to ban GICEs in South Korea.

Lack of compensation for COVID-19-related overtime work and its association with burnout among EMS providers in Korea.

OBJECTIVES: This study examined the association between lack of compensation for COVID-19-related overtime work (LCCOW) and burnout among emergency medical service (EMS) providers in Seoul, Korea. METHODS: We conducted a cross-sectional survey of 693 EMS providers in Seoul, Korea. Participants were classified into 3 groups according to their experience of coronavirus disease 2019 (COVID-19)-related overtime work and LCCOW: (1) "did not experience," (2) "experienced and was compensated," and (3) "experienced and was not compensated." Burnout was measured using the Korean version of the Copenhagen Burnout Inventory, which has 3 subdomains: personal burnout (PB), work-related burnout (WRB), and citizen-related burnout (CRB). Multiple linear regression was applied to examine whether LCCOW was associated with burnout after adjusting for potential confounders. RESULTS: In total, 74.2% of participants experienced COVID-19-related overtime work, and 14.6% of those who worked overtime experienced LCCOW. COVID-19-related overtime work showed a statistically non-significant association with burnout. However, the association differed by LCCOW. Compared to the "did not experience" group, the "experienced and was not compensated" group was associated with PB (ß=10.519; 95% confidence interval [CI], 3.455 to 17.584), WRB (ß=10.339; 95% CI, 3.398 to 17.280), and CRB (ß=12.290; 95% CI, 6.900 to 17.680), whereas no association was observed for the "experienced and was compensated" group. Furthermore, an analysis restricted to EMS providers who worked overtime due to COVID-19 showed that LCCOW was associated with PB (ß=7.970; 95% CI, 1.064 to 14.876), WRB (ß=7.276; 95% CI, 0.270 to 14.283), and CRB (ß=10.000; 95% CI, 3.435 to 16.565). CONCLUSIONS: This study suggests that LCCOW could be critical in worsening burnout among EMS providers who worked overtime due to COVID-19.

Internalized homophobia and HIV testing among Korean gay and bisexual men: a study in a high-income country with pervasive HIV/AIDS stigma.

Limited research has been conducted on factors contributing to HIV testing among sexual minority populations in South Korea (hereafter, Korea), where stigma against homosexuality and HIV/AIDS is pervasive. We used a nationwide cross-sectional survey of 907 Korean cisgender gay and bisexual (GB) men who were HIV-negative or HIV-unknown in 2016. Regarding internalized homophobia (IHP), participants were categorized into tertiles (low, moderate, and high). Past 12-month HIV testing was assessed via a single yes/no question. Using a modified Poisson regression model, we examined the association between IHP and HIV testing among cisgender GB men in Korea. The overall prevalence of obtaining an HIV test was 41.8% among Korean cisgender GB men. We also found a statistically significant association between IHP and past 12-month HIV testing in this population. Specifically, participants with low IHP had a higher prevalence of HIV testing (adjusted PR = 1.37, 95% CI = 1.14-1.65) compared to those with high IHP. Given these findings, more efforts are needed in Korea to enhance GB men's access to HIV testing, such as improving social circumstances to lower IHP of GB men and creating an environment that enables and facilitates GB men to receive HIV testing without stigma against their sexual identity.

Racism, xenophobia, discrimination, and the determination of health.

This Series shows how racism, xenophobia, discrimination, and the structures that support them are detrimental to health. In this first Series paper, we describe the conceptual model used throughout the Series and the underlying principles and definitions. We explore concepts of epistemic injustice, biological experimentation, and misconceptions about race using a historical lens. We focus on the core structural factors of separation and hierarchical power that permeate society and result in the negative health consequences we see. We are at a crucial moment in history, as populist leaders pushing the politics of hate have become more powerful in several countries. These leaders exploit racism, xenophobia, and other forms of discrimination to divide and control populations, with immediate and long-term consequences for both individual and population health. The COVID-19 pandemic and transnational racial justice movements have brought renewed attention to persisting structural racial injustice.

Racism, xenophobia, and discrimination: mapping pathways to health outcomes.

Despite being globally pervasive, racism, xenophobia, and discrimination are not universally recognised determinants of health. We challenge widespread beliefs related to the inevitability of increased mortality and morbidity associated with particular ethnicities and minoritised groups. In refuting that racial categories have a genetic basis and acknowledging that socioeconomic factors offer incomplete explanations in understanding these health disparities, we examine the pathways by which discrimination based on caste, ethnicity, Indigeneity, migratory status, race, religion, and skin colour affect health. Discrimination based on these categories, although having many unique historical and cultural contexts, operates in the same way, with overlapping pathways and health effects. We synthesise how such discrimination affects health systems, spatial determination, and communities, and how these processes manifest at the individual level, across the life course, and intergenerationally. We explore how individuals respond to and internalise these complex mechanisms psychologically, behaviourally, and physiologically. The evidence shows that racism, xenophobia, and discrimination affect a range of health outcomes across all ages around the world, and remain embedded within the universal challenges we face, from COVID-19 to the climate emergency.

Association between discrimination and poor sleep health outcomes among 2192 South Korean gay, lesbian, and bisexual adults: A nationwide cross-sectional survey.

OBJECTIVE: The study aimed to assess the prevalence of poor sleep health outcomes and examine the associations between experiences of discrimination and the sleep health outcomes among lesbian, gay, and bisexual (LGB) adults in Korea. DESIGN & SETTING: The study used data from Rainbow Connection Project I, a nationwide cross-sectional survey of Korean LGB adults, conducted via online in 2016. MEASUREMENTS: Participants were asked about experiences of anti-LGB discrimination and discrimination based on other characteristics (ie, gender, age, place of origin, nationality/race, religion, appearance including height and weight, disability status, and other) in the past 12 months. Using the responses, the participants were categorized into 4 groups: those who experienced (1) none, (2) only anti-LGB discrimination, (3) only other types of discrimination, and (4) both anti-LGB and other types of discrimination. Past-week sleep quality, unrestful sleep, and long sleep latency were included as sleep health outcomes. RESULTS: Of the 2192 participants, 740 (33.8%) had poor sleep quality, 1211 (55.2%) had unrestful sleep, and 681 (31.1%) had long sleep latency in the past week. Participants who experienced both anti-LGB and other types of discrimination had 1.65 times (95% confidence interval [CI] = 1.38-1.98), 1.30 times (95% CI = 1.16-1.45), and 1.58 times (95% CI = 1.31-1.90) higher prevalence of poor sleep quality, unrestful sleep, and long sleep latency, respectively, compared to those without any experiences of discrimination. CONCLUSIONS: Experiencing discrimination may deprive Korean LGB adults of good quality sleep. Interventions that seek to prevent discrimination are needed to promote sleep health among Korean LGB individuals.

Discrimination keeps transgender people awake at night: A nationwide cross-sectional survey of 583 transgender adults in South Korea.

OBJECTIVES: We sought to investigate the association between transgender identity discrimination and sleep problems among transgender people in South Korea (hereafter, Korea), and whether family support for transgender identity plays a protective role in the association. DESIGN & SETTING: We analyzed a nationwide cross-sectional survey of 583 Korean transgender adults which was anonymously conducted through an online platform. MEASUREMENTS: Transgender identity discrimination was assessed using a single-item question. Sleep problems were defined as having any of the following problems: poor sleep quality, short sleep duration, and use of alcohol or sleep medications to fall asleep. Family support for transgender identity was classified into 3 groups as follows: not supportive, supportive, and unaware of participants' transgender identity. RESULTS: Of 583 participants, 383 (65.7%) experienced transgender identity discrimination over the past 12 months. Participants who experienced transgender identity discrimination were 1.48 times (95% confidence intervals [95% CI] = 1.19-1.83) more likely to have any sleep problems, compared to those who never experienced transgender identity discrimination. When stratified by family support level, the associations between transgender identity discrimination and sleep problems remained statistically significant only among those with a family unsupportive (adjusted prevalence ratio [aPR] = 1.64; 95% CI = 1.16-2.31) or unaware (aPR = 1.60; 95% CI = 1.01-2.52) of participants' transgender identity. However, the association was not statistically significant among those with a supportive family (aPR = 1.41; 95% CI = 0.96-2.07). CONCLUSION: Given transphobic environments in Korea, legal and institutional efforts are required to reduce transgender identity discrimination (eg, anti-discrimination laws) as well as to build trans-specific family resources.

Expectation of Rejection and Its Association with Health Care Avoidance and Delay Among 2175 Korean Lesbian, Gay, and Bisexual Adults: A Nationwide Cross-Sectional Survey.

Purpose: The study examined an association between expectation of rejection and health care avoidance and delay (HAD) among lesbian, gay, and bisexual (LGB) adults in South Korea. Methods: We analyzed data from a nationwide cross-sectional survey of 2175 South Korean LGB adults, which was approved by the Korea University Institutional Review Board. We categorized expectation of rejection into tertiles ("low," "medium," and "high" levels) and investigated its association with past 12-month HAD using multivariate modified Poisson regression. Results: After adjusting for covariates, including experiences of discrimination, participants with high levels of expectation of rejection had 1.38-times (95% confidence interval: 1.16-1.65) higher prevalence of HAD compared with those with low levels. Conclusion: Living in anticipation of rejection can negatively impact LGB adults' health care utilization.

Working Alone, Limited Restroom Accessibility, and Poor Menstrual Health Among Cosmetics Saleswomen in South Korea.

Menstrual hygiene management (MHM) at work has been neglected in occupational health research despite its importance for female workers' health. This study investigated the association between hours of working alone and poor menstrual health among 740 cosmetics saleswomen in South Korea. Hours of working alone in a day were classified into 4 categories. MHM was measured by asking "Over the past six months, have you ever experienced that you could not change your sanitary pad when you need to change it at work?" We also measured the experience of dermatopathy due to unchanged sanitary pads. Cosmetics saleswomen who worked alone for 3 h or more in a day reported a higher prevalence of ever being unable to change the sanitary pads (prevalence ratio [PR] 1.84, 95% confidence interval [CI]: 1.37-2.46) and dermatopathy due to unchanged sanitary pads (PR 2.06, 95% CI: 1.18-3.59) than those who worked alone less than 1 h in a day.

Association Between Intimate Partner Violence and Suicidal Ideation Among Female and Male Adults in South Korea: A Nationally Representative Longitudinal Study.

This study sought to assess the prevalence of intimate partner violence (IPV) victimization and to examine the sex-stratified associations between IPV and suicidal ideation in South Korea. This study used nationally representative longitudinal survey data from 2011 to 2020 of the Korean Welfare Panel Study of 9732 married adults at baseline. Participants were annually asked about IPV experiences of verbal abuse, physical threat, or physical assault over the past year in 2011-2019. Suicidal ideation in the past year was assessed in the following year 2012-2020 of IPV experiences. Using multilevel logistic regression models, we examined the associations between IPV and suicidal ideation among married adults. The prevalence of verbal abuse, physical threat, and physical assault was respectively 19.8%, 3.0%, and 1.4% in females (n = 5056); and 18.8%, 2.7%, and 1.0% in males (n = 4676). After adjusting for potential confounders (e.g., lifetime suicidal ideation and random effects of individuals and households) in the same year when participants had IPV experiences, all types of IPV experiences were statistically associated with suicidal ideation in the following year among both females and males, except for physical threat among males. We found a statistically significant association between physical threat and suicidal ideation among females (adjusted odds ratio: 2.22, 95% confidence interval: 1.62, 3.04), whereas no association was observed among males. Our findings suggest that public health interventions related to suicidal behaviors that can be attributable to experiencing IPV are necessary among both females and males in South Korea.

Adolescent Bullying Victimization at Secondary School and Adult Suicidality and Depressive Symptoms Among 2152 Lesbian, Gay, and Bisexual Adults in South Korea.

This study examined the association between adolescent bullying victimization (ABV) and adult mental health among lesbian, gay, and bisexual (LGB) individuals in South Korea (hereafter Korea). We conducted a cross-sectional survey of 2152 Korean LGB adults in 2016. Based on experiences of and reasons for ABV, participants were categorized into four groups: "never bullied," "bullied due to sexual orientation and gender expression (SOGE)," "bullied due to other reasons," and "bullied, reason unspecified." Compared with participants who have never been bullied during adolescence, those who have been "bullied due to SOGE" were 1.56 times, 1.53 times, and 3.59 times more likely to report depressive symptoms, suicidal ideation, and suicide attempts, respectively. Statistically significant associations with all three mental health indicators were also observed among those who have been "bullied due to other reasons": depressive symptoms (adjusted prevalence ratio [aPR] = 1.72), suicidal ideation (aPR = 1.48), and suicide attempts (aPR = 3.15). This study suggests that ABV may increase depressive symptoms and suicidality in adulthood among LGB individuals.
