Use of Menstrual Sanitary Products in Women of Reproductive Age: Korea Nurses' Health Study

OBJECTIVES

The use of menstrual hygiene products and its effect on women's health remains under studied. Patterns of menstrual hygiene product use and the rationale behind choices among Korean women aged 18-45 years were examined.

METHODS

This cross-sectional study was a part of the Korea Nurses' Health Study. A total of 20,613 nurses participated, and 8,658 nurses participated in Module 7 which included a menstrual hygiene products-related survey. The data were collected through the mobile survey using a self-reported questionnaire. Participants' use of menstrual hygiene products and related characteristics were analyzed using frequency (percentage) or mean (SD).

RESULTS

The most common types of menstrual hygiene products across all age groups were disposable menstrual pads (89.0%), followed by cloth menstrual pads (4.5%), tampons (4.2%), and only 1.6% used a menstrual cup. Disposable menstrual pads were the most common across all age groups, but in those aged under 30 years this was followed by tampon use (6%). The most important criteria when choosing a menstrual hygiene product was comfort for disposable menstrual pads (31.3%) and tampons (41.5%), natural ingredients or organic products for cloth menstrual pads (51.4%), and custom fit for the menstrual cup (50.7%). However, for all menstrual hygiene products (except cloth menstrual pads), there was a higher proportion of anxiety than perception of safety, and low awareness of toxic shock syndrome.

CONCLUSION

It is important for women to use menstrual hygiene products with confidence. More research is needed to better understand potential health effects of menstrual hygiene products.

Association between Dietary Habits, Shift Work, and the Metabolic Syndrome: The Korea Nurses' Health Study

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.

Depressive symptoms, professional quality of life and turnover intention in Korean nurses

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.

Depressive Symptoms and Sleep Disturbance in Female Nurses with Atopic Dermatitis: The Korea Nurses' Health Study

Although the prevalence of atopic dermatitis is high in nurses, there is a lack of research on the relationship between atopic dermatitis and depressive symptoms and sleep disturbance among female nurses. This study aimed to determine the effects of atopic dermatitis on depressive symptoms and sleep disturbance in female nurses. We analyzed the data of the Korea Nurses’ Health Study, a large-scale prospective cohort study. A total of 20,613 female hospital nurses aged 20–45 years who participated in the Module 1 of Korea Nurses’ Health Study between July 2013 and November 2014 were included. The chi-square test, t-test, and multivariate ordinal logistic regression analysis were conducted for statistical analysis. The prevalence of atopic dermatitis among female nurses was 11.6%. The levels of depressive symptoms and sleep disturbance were higher in nurses with atopic dermatitis than those without atopic dermatitis. Nurses with atopic dermatitis were 1.16 times more likely to have depressive symptoms and 1.35 times more likely to have sleep disturbance than those without atopic dermatitis after adjusting for confounding variables. The results of this study suggest that additional support should be considered for nurses with atopic dermatitis to improve the occupational environment for managing and preventing the exacerbation of symptoms.

Relationships between depression, family function, physical symptoms, and illness uncertainty in female patients with chronic kidney disease

This study investigated the relationship between depression, family function, physical symptoms, and illness uncertainty in women with chronic kidney disease. Data were collected through structured questionnaire that was completed by 120 women undergoing hemodialysis. Assessment instruments consisted of the Family Adaptability, Partnership, Growth, Affection, Resolve Scale, Symptom Experience Scale, Mishel's Uncertainty in Illness Scale for Adults, and the Center for Epidemiological Studies-Depression Scale. The higher the uncertainty about illness and physical symptoms, the higher is the level of depression, and the better the family function, the lower is the level of depression. Greater uncertainty was associated with poorer family function and worsening physical symptoms. A regression model explained 41% of the variance in depression. Significant predictors of depression were physical symptoms, living alone, illness uncertainty, and "poor" subjective health status. To improve depression of women with chronic kidney disease, nurses need to reduce physical symptoms and illness uncertainty in these patients and improve their subjective health status. In addition, the establishment of a therapeutic support system considering living arrangement will help to reduce depression in women with chronic kidney disease.

[The Disease Management Experience of Patients with Asthma: Grounded Theory Approach]

PURPOSE

The aim of this study was to develop a situation-specific theory to explain the disease management experience of patients with asthma.

METHODS

Twenty participants with asthma were selected using the theoretical sampling method. The data were acquired through in-depth interviews conducted from June to October 2018 and analyzed using the grounded theory approach of Strauss and Corbin.

RESULTS

In total, 69 concepts, 30 subcategories, and 13 categories were generated to explain the disease management experience of patients with asthma. The core category of the disease management experience of patients with asthma was 'management of the disease to prevent aggravation of symptoms over the lifetime'. The disease management process of asthma patients included three steps: the 'cognition phase', the 'adjustment phase', and the 'maintenance phase'. However, some patients remained in the 'stagnation phase' of disease management, which represents the result of the continual pursuit of risky health behavior. There were three types of disease management experiences among patients with asthma: 'self-managing', 'partially self-managing', and 'avoidant'.

CONCLUSION

This study shows that patients with asthma must lead their disease management process to prevent exacerbation of their symptoms. It is imperative to develop nursing strategies and establish policies for effective disease management of patients with asthma based on their individual disease management processes and types.

Factors affecting depressive symptoms in employed hemodialysis patients with chronic renal failure

Depressive symptoms are commonly experienced by hemodialysis patients, generally related to withdrawal from dialysis and compliance with dialysis prescription. This study aimed to identify the factors affecting depressive symptoms in employed hemodialysis patients with chronic renal failure. A cross-sectional, correlational study design was utilized, consisting of 71 patients with chronic renal failure receiving hemodialysis treatment, all employed. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale (CES-D) and fatigue by the Chalder Fatigue Scale. Psychosocial adaptation was measured by the Korean version of the Social Profile. In this study, 32.4% of the participants were depressed. Female patients had a higher score for depressive symptoms than males (25.78 ± 10.15 vs. 16.42 ± 10.25, p = .013). Mental fatigue (β = .425, p < .001), psychosocial adaptation (β = -.275, p < .001), and subjective health (β = -.199, p < .05) were predictive variables of depressive symptoms in hemodialysis patients, with mental fatigue being the most important factor. Depressive symptoms can affect the self-management of hemodialysis patients; therefore, it is important that healthcare providers identify factors that affect depressive symptoms, particularly those associated with mental fatigue.

The effectiveness of virtual reality for people with mild cognitive impairment or dementia: a meta-analysis

BACKGROUND

Virtual Reality (VR) is increasingly used in health-related fields and interventions using VR have the potential to be powerful tools in patient management. The aim of this study was to synthesize the effects of VR interventions for people with mild cognitive impairment (MCI) or dementia.

METHODS

Electronic databases were searched to identify studies that used an experimental design to investigate VR intervention outcomes for patients with MCI or dementia. Studies were excluded if the intervention did not focus on VR, if relevant quantitative outcomes were not reported, or if the intended study purpose was assessment or diagnosis. Data were extracted and analyzed from studies that met criteria. To synthesize the intervention effect sizes (ES), we used random effects models to accommodate heterogeneity in the main effect and sub-group analyses. To identify the potential reason for heterogeneity and compare ES according to the moderator variables, subgroup analyses were conducted based on study characteristics and intervention outcomes.

RESULTS

Data from eleven studies that met eligibility criteria were analyzed. VR intervention delivered to participants with MCI or dementia produced small to medium effects (ES = 0.29, CI = 0.16, 0.42). The ES for studies using semi-immersive technology (ES = 0.37, CI = 0.25, 0.49) was greater than the studies using full-immersive VR (ES = 0.03, CI = -0.14, 0.21). The results showed small-to-medium effects for VR interventions affecting key outcome variables such as cognition (ES = 0.42, CI = 0.24, 0.60) and physical fitness (ES = 0.41, CI = 0.16, 0.65).

CONCLUSION

VR interventions, particularly of the semi-immersive type, are useful for people with MCI or dementia. These results should contribute to the establishment of practical guidelines for VR interventions for patients with cognitive decline.

Korean nurses' adherence to safety guidelines for chemotherapy administration

PURPOSE

Nurses are at risk from handling chemotherapeutic agents. This study aimed to determine adherence to safety guidelines for chemotherapy administration by Korean nurses and to examine the relationship between the hospital safety climate and nurses' adherence to safety guidelines.

METHOD

A descriptive, correlational design with a cross-sectional survey using data from the Korea Nurses' Health Study. For this study, participants included 872 female nurses who had administered chemotherapeutic agents to patients in the last 30 days.

RESULTS

Only a quarter of the participants had high adherence to the safety guidelines, while the majority had moderate to low adherence. The absence of job hindrances and feedback/training - two sub-factors of the hospital safety climate - enhanced the likeliness for nurses to comply with the safety guidelines by almost 1.3 and 1.7 times, respectively.

CONCLUSION

The results imply that the hospital safety climate, particularly feedback/training, and the absence of job hindrances are significantly correlated with adherence to the safety guidelines for chemotherapy administration. Therefore, organisational and policy support is needed to improve the hospital safety climate.

Illness uncertainty and complementary and alternative medicine use in patients undergoing hemodialysis

In this study, we identified the relationships between illness uncertainty, subjective health, and the use of complementary and alternative medicine in patients undergoing hemodialysis. In total, 138 participants who were diagnosed with stages 4-5 chronic kidney disease and currently receiving hemodialysis were included. A cross-sectional, correlational design was utilized. Illness uncertainty was associated with education, monthly income, employment, and subjective health. The use of complementary and alternative medicine was not related to illness uncertainty. Among the subdomains of illness uncertainty, ambiguity and unpredictability were related to subjective health; 24.6% of the participants were currently using complementary and alternative medicine and 19.6% had used it in the past. Such methods were mainly used for the effective treatment of diseases or relief of symptoms; 88.5% of those using complementary and alternative medicine consumed vitamins, specific foods, or dietary supplements. However, the proportion of participants who consulted with health-care providers was not high. When planning nursing interventions for patients treated with hemodialysis, assessments on illness uncertainty and complementary and alternative medicine use are needed.

A Multiplicative Approach to Polyvictimization: A Study of Intimate Partner Violence Types as Risk Factors for Child Polyvictimization in South Korea

Drawing on a new typology of intimate partner violence (IPV), this paper tests the relationship between indicators of totalitarian and anarchic IPV and child polyvictimization incidence and severity. The paper argues for and utilizes a quantitative approach to study polyvictimization severity. Polyvictimization is operationalized as a multiplicative relationship between physical abuse and neglect in a random sample of 204 children from Kyunggi province, South Korea. The indicator of totalitarian IPV significantly predicted polyvictimization severity and incidence even when a traditional measure of intimate terrorism was held constant. The indicator of anarchic IPV significantly predicted polyvictimization severity but not incidence when a traditional measure of intimate terrorism was held constant. Implications are discussed.

Weight change and risk of uterine leiomyomas: Korea Nurses' Health Study

OBJECTIVE

This study examined the associations between anthropometric measures and uterine leiomyomas.

METHODS

This study included a total of 5,062 women (median age of 35.5 years) who had experienced pregnancy and, of these women, 210 reported a diagnosis of uterine leiomyomas within the past 2 years prior to baseline in the Korea Nurses' Health Study. Participants were asked about their anthropometric factors. The odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using logistic regression models.

RESULTS

Mean body mass index (BMI) was 21.8 kg/m² among non-cases. An increase in weight from the age of 18 years to the present was associated with increased risk of uterine leiomyomas (p for trend = .002); compared to women whose weight remained stable, the multivariate ORs (95% CIs) were 1.84 (1.22-2.76) for weight gain of 5-10 kg and 2.00 (1.25-3.20) for weight gain of more than 10 kg since age 18. A similar pattern was observed when the analysis was limited to women with a BMI of 18.5-25 kg/m². Current weight was associated with higher odds of uterine leiomyomas. No associations were found for body size in childhood or in adolescence, weight at age 18, current BMI, or current body size.

CONCLUSIONS

Weight gain in adulthood was associated with increased risk of uterine leiomyomas in Korean women, even in those with normal weight.

Development and validation of an emotional labour scale for nurses

PURPOSE

This study aimed to develop an instrument to measure nurses' emotional labour and to examine the scale's validity and reliability.

BACKGROUND

Nurses experience emotional labour when they interact with patients. In previous research, nurses' emotional labour was measured using tools developed for other occupations, which made it difficult to clarify the attributes specific to nursing.

METHODS

Preliminary items were developed through a literature review, interviews and constructing a conceptual framework. The confirmed 25 items were applied in data collection. Data collected from 304 nurses working at metropolitan area hospitals were utilized to test the preliminary tool's validity and reliability. For this purpose, item analysis, factor analysis, Pearson correlation coefficients and Cronbach's alpha were used.

RESULTS

The final scale comprised 16 items, divided and three factors. The factors comprised "emotional control effort in profession," "patient-focused emotional suppression," and "emotional pretense by norms." The explanatory variance of the three factors was 52.1%. Cronbach's α was 0.81, and the split-half coefficient was 0.84.

CONCLUSIONS

Results indicate that the proposed scale was valid and reliable, and suitable for assessing nurses' emotional labour.

IMPLICATIONS FOR NURSING MANAGEMENT

The scale could contribute to devising an efficient strategy to manage nurses' emotional labour.

Radiation safety education and compliance with safety procedures-The Korea Nurses' Health Study

AIMS AND OBJECTIVES

To examine the current state of radiation safety education and its influence on nurses' compliance with safety procedures.

BACKGROUND

Use of radiation in therapy and diagnosis has prolonged and improved millions of lives, but it presents potential hazards for healthcare professionals.

DESIGN

A cross-sectional design.

METHODS

Participants included 1,672 female nurses of childbearing age who had recently been exposed to radiation-emitting generators or radiation. Quantitative data were taken from the Korea Nurses' Health Study, the Korean version of the Nurses' Health Study conducted in the USA. Confounding variables included sociodemographic factors, duration of employment in a department where work involved radiation, hospital's geographical location, bed size and hospital safety climate. Statistical analyses included descriptive statistics, Spearman's correlation coefficients and multivariable ordinal logistic regression.

RESULTS

Half (50.3%) of nurses received no safety training, whereas the other half received some safety training as follows: only once (14.4%), irregularly (10.2%) and regularly (25.1%). Of the six radioactive safety compliance questionnaires, 29.4%, 20.2%, 30.7% and 19.7% complied to none, one, two and more than three, respectively. After controlling for confounding variables, relative to that observed with no safety education, irregular education that occurred more than twice (OR = 1.597, CI = 1.177-2.164) and regular education (OR = 2.223, CI = 1.770-2.792) increased the likelihood that nurses would comply with safety procedures.

CONCLUSIONS

Low levels of safety education and adherence raise critical concerns regarding nurses' well-being. As routine safety education increases safety adherence, healthcare managers and policymakers should emphasise regular safety education.

RELEVANCE TO CLINICAL PRACTICE

Radiation safety education for nurses and their compliance with safety procedures have seldom been discussed in South Korea. However, as nurses' safety is directly related to the quality of patient care, additional safety education should be provided for hospital nurses to minimise their occupational exposure to harmful radioactive substances in clinical settings.

Gastroesophageal reflux disease and its related factors among women of reproductive age: Korea Nurses' Health Study

Background

Recently, the number of patients diagnosed with gastroesophageal reflux disease (GERD) has increased in Korea. Risk factors of GERD include age, sex, medication use, lack of physical exercise, increased psychological stress, low or high body mass index (BMI), unhealthy eating habits, increased alcohol consumption, and cigarette smoking. However, few studies examined the major factors affecting GERD in women of childbearing age. Therefore, this study assessed the risk factors of GERD among 20,613 female nurses of reproductive age using data from the Korea Nurses’ Health Study.

Methods

Participants were recruited from July 2013 to November 2014. They provided their history of GERD 1 year prior to data collection, along with information on their demographic characteristics, health-related behaviors, diet, medical history, and physical and psychological factors. Of the total sample, 1184 individuals with GERD diagnosed in the year prior to the study were identified. Propensity score matching was used for analysis.

Results

Cigarette smoking, increased alcohol consumption, low or high BMI, depression, and increased psychosocial stress were associated with the prevalence of GERD among Korean young women. Multivariate ordinal logistic regression analysis revealed significant positive relationships between GERD and being a former smoker; having a low (< 18.5 kg/m²) or high BMI (> 23 kg/m²); and having mild, moderate, moderately severe, and severe depression.

Conclusions

Smoking, BMI, and depression were associated with GERD. To reduce this risk among female nurses, intervention strategies are required to help nurses maintain a normal weight and manage their depression.

Binge eating disorder and depressive symptoms among females of child-bearing age: the Korea Nurses' Health Study

BACKGROUND

Most studies regarding the relationship between binge eating disorder (BED) and depression have targeted obese populations. However, nurses, particularly female nurses, are one of the vocations that face these issues due to various reasons including high stress and shift work. This study investigated the prevalence of BED and the correlation between BED and severity of self-reported depressive symptoms among female nurses in South Korea.

METHODS

Participants were 7,267 female nurses, of which 502 had symptoms of BED. Using the propensity score matching (PSM) technique, 502 nurses with BED and 502 without BED were included in the analyses. Data were analyzed using descriptive statistics, Spearman's correlation, and multivariable ordinal logistic regression analysis.

RESULTS

The proportion of binge eating disorder was 6.90% among the nurses, and 81.3% of nurses displayed some levels of depressive symptoms. Multivariable ordinal logistic regression analysis revealed that age (40 years old and older), alcohol consumption (frequent drinkers), self-rated health, sleep problems, and stress were associated with self-reported depression symptoms. Overall, after adjusting for confounders, nurses with BED had 1.80 times the risk (95% CI = [1.41-2.30]; p-value < 0.001) of experiencing a greater severity of self-reported depression symptoms.

CONCLUSIONS

Korean female nurse showed a higher prevalence of both binge eating disorder and depressive symptoms, and the association between the two factors was proven in the study. Therefore, hospital management and health policy makers should be alarmed and agreed on both examining nurses on such problems and providing organized and systematic assistance.

A Health Behavior Prediction Model for Patients With Coronary Artery Disease

The aim of this study was to determine the relationships among functional status, hostility, social support, illness perceptions, and health behaviors in patients with coronary artery disease using structural equation modeling. Participants comprised 215 patients with coronary artery disease who had received percutaneous coronary artery intervention or a coronary artery bypass graft in two general hospitals in Seoul, Korea. Using structured interviews with questionnaires, data accrued from July to August, 2015. Fitness of the model was verified with AMOS 21.0. As social support increased, it negatively aligned with cognitive-illness perceptions. Higher levels of hostility and greater negative cognitive-illness perceptions aligned with negative emotional-illness perceptions. Social support indirectly affected emotional-illness perceptions. Lower levels of functional status, greater social support, and more positive cognitive-illness perceptions aligned with health behaviors. Social support indirectly affected health behaviors. In conclusion, nurses should focus on coronary artery disease patients’ physical functions and cognitive-illness perceptions to provide support.

The Korea Nurses' Health Study: A Prospective Cohort Study

BACKGROUND

The Korea Nurses' Health Study (KNHS) is a prospective cohort study of female nurses, focusing on the effects of occupational, environmental, and lifestyle risk factors on the health of Korean women.

MATERIALS AND METHODS

Female registered nurses aged 20-45 years and living in the Republic of Korea were invited to join the study, which began in July 2013. They were asked to complete a web-based baseline survey. The study protocols and questionnaires related to the KNHS are based on the Nurses' Health Study 3 (NHS3) in the United States, although they were modified to reflect the Korean lifestyle. Participants were asked about demographic, lifestyle factors, disease history, occupational exposure, reproductive factors, and dietary habits during their adolescence: Follow-up questionnaires were/will be completed at 6-8 month intervals after the baseline survey. If a participant became pregnant, she answered additional questionnaires containing pregnancy-related information.

RESULTS

Among 157,569 eligible female nurses, 20,613 (13.1%) completed the web-based baseline questionnaire. The mean age of the participants was 29.4 ± 5.9 years, and more than half of them were in their 20s. Eighty-eight percent of the participants had worked night shifts as a nurse (mean, 5.3 ± 4.3 nights per month). Approximately 80% of the participants had a body mass index below 23 kg/m². Gastrointestinal diseases were the most prevalent health issues (25.9%).

CONCLUSIONS

The findings from this prospective cohort study will help to identify the effects of lifestyle-related and occupational factors on reproductive health and development of chronic diseases in Korean women.

Body Mass Index, Body Shape Satisfaction, and Weight Control Behaviors among Korean Girls

The present study investigated the relations among Body Mass Index, body shape satisfaction, and weight control behaviors among Korean girls. Subjects were 266 girls ( M age = 16.6 yr., SD = .9), recruited from two girls' high schools in Seoul, Korea. Based on Body Mass Index, 73.7% were normal weight, 22.9% were underweight, and 3.4% were overweight. 174 girls (65.4%) indicated that they were currently using any weight control method. Weight control behaviors differed significantly by Body Mass Index category, with girls whose Body Mass Indexes indicating normal weight being more likely to claim they used weight control behaviors. Also, the girls who rated themselves as dissatisfied with their body shape were more likely to report weight control behaviors.
