Aim The purpose of this study was to identify the effects of depressive symptoms and professional quality of life on turnover intention. Background The high turnover rate of nurses is a critical healthcare issue globally. Introduction Nurses often experience depressive symptoms and compassion fatigue due to the efforts of patient care. The impact of such psychological health issues on turnover intention needs to be confirmed. Methods Participants were 10 163 female nurses who completed an online or mobile survey using the Korea Nurses’ Health Study. To identify the influencing factors on the turnover intention of nurses, descriptive statistics, spearman’s correlation coefficients and multivariable ordinal logistic regression were performed. Results The turnover intention increased by about 2.81–4.60 times when depressive symptom was moderate or more, 1.14 times when secondary traumatic stress disorder was moderate or more, and 1.54 times when burnout was moderate or more. When compassion satisfaction was moderate or high, the turnover intention decreased by 0.72 and 0.52 times. Discussion Korean nurses demonstrated high levels of depressive symptoms, secondary traumatic stress and burnout, while demonstrating lower levels of compassion satisfaction. The results of this study demonstrate that depressive symptoms, secondary traumatic stress, burnout and compassion satisfaction affect turnover intention. Conclusions To reduce nurses’ turnover intention, it is necessary to reduce depressive symptoms and enhance the quality of professional life. Implications for nursing and health policy Hospital managers need to maintain adequate nurse‐to‐patient ratios and provide nurses with a supportive work environment. Also, health policymakers need to identify factors affecting hospital nurses’ turnover intention and provide strategies to address them. These conditions may reduce the excessive workload placed on nurses, thereby preventing depression and burnout and improving nurses’ quality of work–life.

Nurses often experience work-related physical and mental fatigue. This study sought to identify the levels of physical and mental fatigue present among Korean female nurses and discern factors influencing their onset. This cross-sectional study analyzed data from the Korea Nurses’ Health Study (KNHS). A total of 14,839 hospital nurses were assessed by hierarchical regression analysis. The mean scores of physical and mental fatigue were 12.57 and 5.79 points, respectively. After adjusting for confounding variables, the work department had a significant influence on both physical and mental fatigue, that is, nurses working in special care units experienced greater degrees of both physical and mental fatigue than those working in general units. Nurse fatigue is an important consideration to monitor to ensure nurses’ continued wellbeing as well as good patient safety levels. Therefore, it is necessary to establish a strategy to mitigate nursing fatigue while considering the characteristics of specific departments. In nursing practice, the introduction of a counseling program and guarantee of rest time that can alleviate the mental and physical fatigue of nurses working in special care units should be considered.

Aim To identify the factors affecting fear, anxiety and depressive symptoms among frontline nurses working with COVID‐19 patients or are in charge of COVID‐19 screening in Korea. Background Nurses are at a higher risk of COVID‐19 infection because they are in closer, longer‐duration contact with patients. These situations can negatively affect the mental health of nurses. Methods This study analysed data from COVID‐19 module in the Korean Nurses’ Health Study. Data from 906 participants were analysed. To identify the factors influencing mental health, descriptive statistics, Pearson’s correlation and hierarchical multiple regression analyses were performed. Results Caring for patients who are COVID‐19‐positive increased levels of fear, anxiety and depressive symptoms of nurses. The hospital safety climate influenced mental well‐being among nurses. Conclusion Caring for patients with COVID‐19 had a negative impact on fear, anxiety and depressive symptoms. However, the higher was the perceived hospital safety climate, the lower were the nurses’ psychological symptoms. Further research on the mental health of nurses is warranted. Implications for nursing and health policy Institutions should manage human resources to enable periodic rotation of nurses’ work and working periods related to COVID‐19. In addition, hospital managers should provide sufficient personal protective equipment, related education, and safety climate.

Metabolic syndrome (MetS) is an important public health problem, and unhealthy dietary habits and shift work are considered major factors that increase the prevalence of MetS. The purpose of this study was to examine whether dietary habits, alcohol drinking, and shift-working were associated with development of MetS in shift-working female nurses. This study analyzed cross-sectional survey data from the Korea Nurses’ Health Study (KNHS). Of the 1638 nurses, 403 participants were selected based on the propensity score matching method (PSM). These participants had either no or more than three MetS determinant factors. Analysis was conducted by using multivariable logistic regression to confirm the factors influencing MetS. The prevalence of MetS in this group (1638 participants) was 5.6% (92 participants). Consumption of over 50% of daily calorie intake after 7 p.m., consumption of carbonated drinks, family history of diabetes, and non-shift work were significant factors influencing MetS. Nurses are one of the at-risk groups for unhealthy dietary habits due to the nature of their work. Therefore, nurse managers should include regular dietary education for nurses and continue their policy efforts to resolve health problems that may arise in connection with nurses’ work.

To enhance the life satisfaction of the elderly with multimorbidity, it is necessary to investigate the relevant factors and to examine the differences in factors according to gender. The aim of this study was to identify factors affecting life satisfaction of the elderly with multimorbidity in the community by gender in Korea. We analyzed data from 2140 participants with multimorbidity who were aged 65 or older and participated in the Korean Longitudinal Study of Ageing (KLoSA) in 2016. A multivariate linear regression analysis was conducted to examine the factors affecting life satisfaction among male and female older participants with multimorbidity. The most common pattern of multimorbidity of women was hypertension and arthritis/rheumatism, while that of men was hypertension and diabetes mellitus. Some factors, such as depression, exercise, and number of chronic diseases, affected both male and female participants, but others related to life satisfaction varied by gender. Therefore, it is necessary to consider the characteristics of multiple chronic diseases, and policy support should be provided in consideration of gender differences to improve the life satisfaction of the elderly.

The purpose of this study was to identify the factors affecting subjective cognitive impairment. We analyzed data from the 2019 Korea Community Health Survey and enrolled 68,546 middle-aged adults, aged 50 to 64 years, and 74,547 older adults, aged 65 years and older, in this study. Multiple logistic regression analysis was performed to identify factors influencing subjective cognitive impairment. Of the participants, 11,926 (17.4%) middle-aged and 21,880 (29.4%) older adults living in the community reported subjective cognitive impairment. Major factors that influenced subjective cognitive impairment in both middle-aged and older adults were gender, subjective stress, depressive symptoms, and alcohol drinking. In contrast to middle-aged adults, the marital status of older adults affected subjective cognitive impairment. Therefore, the factors affecting subjective cognitive impairment in middle-aged and older adults need to be considered for screening and management to prevent cognitive impairment and dementia. In particular, it is necessary to evaluate and manage stress and depressive symptoms from middle age to prevent subjective cognitive impairment.

To identify the mediating and moderating roles of depressive symptoms in the relationship between workplace violence and nurses' turnover intention in South Korea. Background: Workplace violence and depressive symptoms are known to influence turnover intentionsof employees. Introduction: Among healthcare workers, nurses may be at the greatest risk of exposure to workplace violence because they have frequent contact with patients and families of patients. Depressive symptoms reported to be related to workplace violence are one set of factors affecting turnover intention. Methods: A cross-sectional study was designed and employed to investigate mediation and moderation roles of depressive symptoms between workplace violence and turnover intention. Results: Verbal violence and sexual harassment increased depressive symptoms, which in turn increased turnover intentions in a sample of Korean nurses. Depressive symptoms showed partial mediation effects between verbal violence and sexual harassment and turnover intention. Depressive symptoms showed moderating effects on sexual harassment and turnover intention. Discussion: It is necessary to reduce turnover intention not only by preventing violence but also by managing depressive symptoms in nurses who have experienced verbal violence and sexual harassment. Conclusion: Depressive symptoms were shown to have a mediating and moderation roles on the relationship between WPV and turnover intention. Implications for nursing and health policy: Hospital managers such as hospital and nursing directors should provide effective policies to prevent verbal violence and sexual harassment to reduce turnover intention in the workplace. It is needed to educate patients and patient caregivers about the importance of preventing violence against nurses. Policies should be established to provide regular check-ups for depressive symptoms and psychological support for nurses who have experienced WPV.

Controlling weight and dietary intake are important for hypertensive patients to manage their blood pressure. However, the interaction effect of gender and age on weight and dietary intake is not well known. The aim of this study was to examine the main and interaction effects of age and gender on body mass index (BMI) and dietary intake in hypertensive patients. We analyzed data from 4287 participants with hypertension (1600 participants 45–64 years old and 2687 participants 65 years or older) who participated in the Korea National Health and Nutrition Examination Survey (2013–2016). Two-way ANOVAs were conducted to examine the main and interaction effects of age and gender on BMI and dietary intake. Gender and age had significant main effects on BMI, intake of energy, cholesterol, sodium, and potassium. However, both gender and age illustrated interaction effects on BMI (F = 8.398, p = 0.004), energy intake (F = 12.882, p < 0.001), and cholesterol intake (F = 6.107, p = 0.014), while not showing any significant interaction effects on sodium (F = 3.547, p = 0.060) and potassium (F = 3.396, p = 0.066). Compared to the middle-aged group, BMI, energy intake, and cholesterol intake decreased in the older-aged group. However, the declines were steeper in men than in women. Therefore, both gender and age need to be considered for weight and dietary intake management for hypertensive patients.
