Research trends in the Korean Journal of Women Health Nursing from 2011 to 2021: a quantitative content analysis.

PURPOSE: Topic modeling is a text mining technique that extracts concepts from textual data and uncovers semantic structures and potential knowledge frameworks within context. This study aimed to identify major keywords and network structures for each major topic to discern research trends in women's health nursing published in the Korean Journal of Women Health Nursing (KJWHN) using text network analysis and topic modeling. METHODS: The study targeted papers with English abstracts among 373 articles published in KJWHN from January 2011 to December 2021. Text network analysis and topic modeling were employed, and the analysis consisted of five steps: (1) data collection, (2) word extraction and refinement, (3) extraction of keywords and creation of networks, (4) network centrality analysis and key topic selection, and (5) topic modeling. RESULTS: Six major keywords, each corresponding to a topic, were extracted through topic modeling analysis: "gynecologic neoplasms," "menopausal health," "health behavior," "infertility," "women's health in transition," and "nursing education for women." CONCLUSION: The latent topics from the target studies primarily focused on the health of women across all age groups. Research related to women's health is evolving with changing times and warrants further progress in the future. Future research on women's health nursing should explore various topics that reflect changes in social trends, and research methods should be diversified accordingly.

Factors Affecting the Quality of Life in Low-Income Older Adults with Sarcopenia: A Cross-Sectional Study.

PURPOSE: This study aimed to identify the factors influencing quality of life (QoL) of low-income older adults (LOAs) with sarcopenia. METHODS: A convenience sample of 125 older adults was recruited from Jeonbuk Province, South Korea. Data were collected using a self-report questionnaire that included nutritional status, the Depression Anxiety Stress Scale-21, and the World Health Organization Quality of Life Instrument-Older Adults Module. Additionally, grip strength and appendicular skeletal muscle mass, were evaluated, along with the short physical performance battery. RESULTS: Sarcopenia and severe sarcopenia were observed in 43.2% and 56.8% of participants, respectively. Using multiple regression analysis, depression (ß = -.40, p < .001), nutritional status (ß = .24, p = .003), and anxiety (ß = -.15, p = .042) were identified as factors affecting the QoL of the older adults in low-income groups with sarcopenia, the explanatory power of these variables was 44%. CONCLUSION: The results of this study can be used to develop a nursing intervention program and establish policies to improve depression, anxiety, and nutritional status to enhance QoL of LOAs with sarcopenia.

Factors influencing health-related quality of life in older adult women with sarcopenia: analysis of the Korean National Health and Nutrition Examination Survey 2019.

PURPOSE: This study aimed to identify factors influencing the health-related quality of life (HRQoL) of older adult women with sarcopenia. METHODS: The study was secondary data analysis using data from the 2019 Korea National Health and Nutrition Examination Survey. The final sample consisted of 142 women aged 60 years and older with sarcopenia and were selected from 8,110 women. The participants was analyzed using complex descriptive statistics, independent t-test, and regression. RESULTS: In terms of HRQoL, three general characteristics were found to be influential, with an explanatory power of 56.0%: difficulty climbing stairs, difficulty working, and perceived health status. Having no or mild difficulty when climbing stairs (B=.20, p=.001; B=.21, p<.001) and no or mild difficulty when working (B=.25, p=. 002; B=.208, p=.013) had a significant effect on HRQoL compared to severe difficulty. Having good or ordinary perceived health status had a significant effect on the HRQoL (B=.11, p<.001; B=.09, p<.001). CONCLUSION: Based on study findings that the HRQoL of older adult women with sarcopenia were influenced by difficulty climbing stairs and working, as well as good perceived health status, healthcare providers should assist elderly women to maintain physical activities in their daily lives.

Relationships among sexual function, marital intimacy, type D personality and quality of life in patients with ovarian cancer, with spouses.

OBJECTIVE: This study aimed to identify the relationships among sexual function, marital intimacy, type D personality and quality of life (QoL) in patients with ovarian cancer, with spouses. METHODS: A descriptive cross-sectional design was used, and 104 patients were recruited using convenience sampling, from the inpatient and outpatient gynaecological clinics of two tertiary medical centres using structured questionnaires. RESULTS: Of the 104 participants, 31.7% were classified as having a type D personality. The type D group had lower marital intimacy, higher symptoms and lower QoL than the non-type D personality group. The results of a hierarchical regression analysis showed that monthly income, symptoms, marital intimacy and type D personality were independent factors that influenced QoL in patients with ovarian cancer, with spouses. CONCLUSION: Demographic characteristics, symptoms, marital intimacy and type D personality should be considered in patients with ovarian cancer, with spouses when evaluating QoL. Intervention strategies considering these characteristics could improve QoL for patients with ovarian cancer patient, with spouses.

Associated factors of depression in pregnant women in Korea based on the 2019 Korean Community Health Survey: a cross-sectional study.

Purpose: Various individual and social factors influence depression in pregnant women. The purpose of this study was to identify the influence of socioeconomic status, health behaviors, and health status on depression of pregnant women in Korea. Methods: This study analyzed data from the 2019 Korean Community Health Survey conducted from August to October 2019. A structural questionnaire with Patient Health Quetsionnaire-9 (PHQ-9), health behavior, health status, and psychological characteristics was used. The data of 1,096 pregnant women between the ages of 19 and 55 years were analyzed using descriptive statistics, independent-test and chi-square tests, and multiple regression. Results: The mean score of prenatal depression as measured by the PHQ-9 during pregnancy was 2.35 points out of 0 to 27 points. Low income (B=0.69, p<.001), low-education level (B=0.70, p<.001), skipping breakfast (B=0.34, p=.001), less than 8 hours of sleeping (B=0.26, p=.009), binge drinking during pregnancy (B=0.46, p=.001), and stress (B=1.89, p<.001) were significantly associated with increased depression scores. In contrast, depression scores significantly decreased as subjective health status (B=-0.59, p<.001) and subjective oral health status (B=-.17, p=.003) increased. Conclusion: Findings support the need for healthcare policies and clinical screening to alleviate prenatal depression, especially for pregnant women with low socioeconomic status, poor health behavior, poor health status, and high stress.

Factors influencing quality of life in low-income women with young children in Korea: a cross-sectional study.

Purpose: This study aimed to investigate the effects of health-promoting behaviors (HPB), marital intimacy, and parenting stress on the quality of life (QoL) of low-income women with young children in Korea, an underserved group. Methods: This cross-sectional survey employed a descriptive correlational design. Using convenience sampling, 123 low-income women with children younger than 6 years were recruited from 14 health and community centers in Jeonju, Korea, from June 2020 to May 2021. Participants completed a questionnaire on QoL, HPB, marital intimacy, and parenting stress. Data were analyzed using descriptive statistics, independent t-test, analysis of variance, Pearson correlation, and hierarchical regression analysis. Results: Participants, who were on average 37.41±3.65 years old and had 1 to 2 children (n=98, 79.7%), reported a mid-level (3.14 out of 1-5) of QoL. Marital intimacy (ß=.38, p<.001) was the most influential factor on the QoL of low-income women with young children. In descending order, HPB (ß=.35, p<.001) and non-employment status (ß=-.21, p=.003) had a significant influence on QoL (F=15.64, p<.001), and the overall explanatory power was 49.0%. Conclusion: Considering the mid-level QoL of low-income women with young children, programs aimed at improving the QoL of low-income women need to promote marital intimacy and maintain HPB, while considering their employment status. Strategies that include couple counseling, health care to encourage healthy lifestyles, and reemployment education are needed.

[Trajectories of subjective health status among married postmenopausal women based on the ecological system theory: a longitudinal analysis using a latent growth model]. / 생태체계 ì´ë¡ ì„ ì ìš©í•œ 기혼 폐경 여성의 ì£¼ê´€ì  건강상태에 대한 ê¶¤ì : ìž ìž¬ì„±ìž¥ëª¨í˜•ì„ 이용한 ì¢ ë‹¨ì—°êµ¬.

Purpose: This study investigated the trajectory of subjective health status in married postmenopausal women and aimed to identify predictive factors affecting subjective health status. Methods: Data were obtained from women who participated in wave 4 (2012) of the Korean Longitudinal Survey of Women & Families Longitudinal Study and continued to the latest phase (wave 7, 2018). A latent growth model (LGM) was used to analyze data from 1,719 married postmenopausal women in the framework of the ecological system theory. Results: The mean age of the participants at wave 4 was 56.39±4.71 years, and the average subjective health status was around the midpoint (3.19±0.84). LGM analysis confirmed that subjective health status decreased over time (initial B=3.21, slope B=-0.03). The factors affecting initial subjective health were age, body mass index, frequency of vigorous physical activity (microsystem level), marital satisfaction (mesosystem level), and medical service utilization (macrosystem level). Medical service utilization and the frequency of vigorous physical activity were identified as predictive factors affecting the slope in subjective health status. The model fit was satisfactory (TLI=.92, CFI=.95, and RMSEA=.04). Conclusion: This analysis of the trajectory of subjective health status of married postmenopausal women over time confirmed that subjective health is influenced by overall ecological system factors, including the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Therefore, it is necessary to assess physical activity and support policies promoting access to medical services in order to improve the subjective health status of married postmenopausal women.

Lifestyle Interventions for Adults with Infertility.

With a significant increase in the age-standardized prevalence of infertile men and women, infertility has become a widespread global issue. Furthermore, infertility has led to increased stigma and disease burden. The causes of infertility include lifestyle factors such as obesity, an unbalanced diet, and physical activity. To increase the rate of successful pregnancy, infertile men and women must improve their health and fertility through lifestyle improvements.

Relationships among type-D personality, fatigue, and quality of life in infertile women.

PURPOSE: The objective of the present study was to investigate the prevalence of the type D personality and identify the relationship between type D personality, fatigue and quality of life (QoL) in infertile women. METHODS: A total of 149 infertile women were recruited between October 2020 and January 2021. The participants were assessed through self-administered questionnaires using the type- D Personality Scale-14, Fatigue Severity Scale, and Fertility QoL Instrumental Questionnaire. Data were analyzed using the independent t-test, chi-square test, Pearson's correlation coefficients, and multiple regression analysis using the SPSS/WIN 25.0 program for Windows. RESULTS: Approximately 40.9% of infertile women were classified into the type D personality group, which showed significantly higher fatigue and lower QoL than the non-type D personality group. Fatigue was the most influential factor on the QoL of infertile women (ß=-.23, p=.003), followed by the duration of infertility treatment (ß=-.22, p=.003), type D personality (ß=-.18, p=.025), and relationship with spouse (ß=-.17, p=.024). These variables account for approximately 22% of the variance. CONCLUSIONS: Intervention programs that consider fatigue, type D personality, relationship with spouses, and treatment duration may be useful for improving QoL in infertile women.

The Effect of COVID-19-Related Lifestyle Changes on Depression.

OBJECTIVE: This study aimed to identify the effect of coronavirus disease (COVID-19)-related lifestyle changes on depression. METHODS: This secondary data analysis study included 229,269 adults from a community health survey conducted in the South Korea in 2020. Data were collected using a structured questionnaire about participants' lifestyle changes related to COVID-19 and the Patient Health Questionnaire-9. The data were analyzed using a complex sample independent t-test, analysis of variance, Pearson's correlation coefficient, and multiple regression analysis. RESULTS: The mean age of the participants was 48.76; 49.6% were male, and 50.4% were female. The multiple regression showed that depression increased due to COVID-19-related lifestyle changes (physical activity, sleep duration, consumption of convenience foods, alcohol consumption, smoking, and use of public transportation). The explanatory power was 27.3%, and the model was suitable (Wald F=63.75, p<0.001). CONCLUSION: This study identified the effect of COVID-19-related lifestyle changes on depression, and the results have implications for future depression-relieving interventions.

Factors affecting quality of life in low-income overweight and obese women: The mediating effects of health-promoting behaviors.

BACKGROUND: It is necessary to comprehensively consider the personal and environmental factors of women who experience overweight or obesity and low-income households (WOOL) to improve their quality of life (QoL). AIMS: The aim of this study was to test a hypothetical path model to estimate the effects of self-efficacy, psychological distress, social support, and health-promoting behaviors (HPB) on QoL and verify the mediating effects of HPB among WOOL. METHODS: A total of 151 women with a monthly household income less than 50% of the national median income at eight welfare centers in South Korea participated in this study. Data were collected from January to December 2019 and analyzed using SPSS 25.0 and Amos 23.0. RESULTS: The fit indices of the model were adequate (χ2  = 0.197, p = .657; normed χ2  = 0.197, GFI = 0.999, CFI = 1.000, NFI = 0.999, TLI = 1.000, RMSEA = 0.000, and SRMR = 0.005). Self-efficacy had significant indirect and total effects on QoL (ß = 0.064, p = .004, 95% CI [0.015, 0.139]; ß = 0.064, p = .004, 95% CI [0.015, 0.139]). HPB completely mediated the path of self-efficacy to QoL. Social support had significant total, direct, indirect, and total effects on QoL (ß = 0.326, p = .001, 95% CI [0.010, 0.025]; ß = 0.047, p = .015, 95% CI [0.008, 0.120]; ß = 0.373, p = .001, 95% CI [0.015, 0.369]). HPB partially mediated the path of social support to QoL. Psychological distress had significant direct effects on QoL (ß = -0.307, p = .001, 95% CI [-0.022, -0.007]). Self-efficacy, psychological distress, social support, and HPB explained 42.3% of the total variance in QoL. LINKING EVIDENCE TO ACTION: Integrated nursing interventions that consider self-efficacy, psychological distress, social stress, and HPB can be useful for improving the QoL of WOOL.

Symptoms, resilience, coping, and psychosocial adjustment in women with gynaecological cancer in South Korea: A cross sectional study.

PURPOSE: This cross-sectional study aimed to evaluate the relationship between symptoms, resilience, coping, and psychosocial adjustment, and to identify the influence of these variables on the psychosocial adjustment in women with gynaecological cancer in South Korea. METHODS: A correlational research design was employed based on the stress-coping theory of Lazarus and Folkman. A total of 150 women with gynaecological cancer admitted to a Korean tertiary hospital were included via convenience sampling. Data were collected using structured questionnaires between January and April 2018. Data analyses included descriptive statistics, independent t-test, χ2 test, analysis of variance, Pearson's correlation coefficient, and hierarchical multiple regression using the SPSS WIN 25.0 program. RESULTS: The study found that symptoms had the strongest association with psychosocial adjustment in women with gynaecological cancer. Psychosocial adjustment showed a statistically significant relationship with symptoms (r = 0.34, p < .001), resilience (r = -.43, p < .001), and coping (r = -.32, p < .001). A hierarchical multiple regression analysis demonstrated that symptoms (ß = 0.33, p < .001), resilience (ß = -.30, p < .001), and coping (ß = -.17, p = .032) accounted for 28.1% of the variance in psychosocial adjustment. CONCLUSIONS: It is pertinent for healthcare providers to assess and develop symptom management to provide resilience and coping strategies for gynaecological cancer women and improve their psychosocial adjustment.

Maternal, infant, and perinatal mortality statistics and trends in Korea between 2018 and 2020.

PURPOSE: This study aimed to identify maternal, infant, and perinatal mortality using the nationalpopulation data of South Korea between 2018 and 2020, and to analyze mortality rates according tocharacteristics such as age, date of death, and cause of death in each group. This study updates themost recent study using 2009 to 2017 data. METHODS: Analyses of maternal, infant, and perinatal mortality were done with data identifiedthrough the supplementary investigation system for cases of death from the Census of PopulationDynamics data provided by Statistics Korea from 2018 to 2020. RESULTS: Between 2018 and 2020, a total of 99 maternal deaths, 2,427 infant deaths, and 2,408 perinatal deaths were identified from 901,835 live births. The maternal mortality ratio was 11.3 deathsper 100,000 live births in 2018; it decreased to 9.9 in 2019 but increased again to 11.8 in 2020. Thematernal mortality ratio increased steeply in women over the age of 40 years. An increasing trend inthe maternal mortality ratio was found for complications related to the puerperium and hypertensive disorders. Both infant and perinatal mortality continued to decrease, from 2.8 deaths per 1,000live births in 2018 to 2.5 in 2020 and from 2.8 in 2018 to 2.5 in 2020, respectively. CONCLUSION: Overall, the maternal, infant, and perinatal mortality statistics showed improvements.However, more attention should be paid to women over 40 years of age and specific causes of maternal deaths, which should be taken into account in Korea's maternal and child health policies.

A serial multiple mediator model of sense of coherence, coping strategies, depression, and quality of life among gynecologic cancer patients undergoing chemotherapy.

PURPOSE: This study evaluated whether coping strategies (positive reframing, planning, and active coping) and depression mediate the relationship between sense of coherence (SOC) and quality of life (QoL) using a serial multiple mediator model in patients with gynecologic cancer who are undergoing chemotherapy. METHODS: A sample of 148 participants, with a mean age of 52.17 years (range 20-75) and diagnosed with gynecological cancer (e.g., cervix, ovary and endometrium) was surveyed in a cross-sectional study. Data were collected using a structured self-reporting questionnaire. A serial multiple mediator model was analyzed to explain sequential causality among two mediators (coping strategy and depression) and to investigate the direct and indirect effects of the mediator model in SPSSWIN 26.0 and PROCESS macro program. RESULTS: The conceptual serial mediation model of SOC, positive reframing, depression, and QoL revealed a significant positive total effect (coefficient c = 13.099, SE = 1.647, p < 0.001). The path through single mediation of positive reframing (Effect = 0.925) and depression (Effect = 5.942) and that through both mediators (Effect = 1.161) were statistically significant. The total indirect effect was also statistically significant (Effect = 8.028). Moreover, the conceptual serial mediation model on SOC, planning, depression, and QoL revealed a significant positive total effect (coefficient c = 13.099, SE = 1.647, p < 0.001). The path through both mediation of planning and depression (Effect = 1.162) and the total indirect effect were statistically significant (Effect = 8.172). CONCLUSIONS: Helping patients with gynecologic cancer undergoing chemotherapy to strengthen SOC may improve QoL by equipping them with efficient positive reframing or planning strategies to reduce depression.

Factors Related to Maternal Oral Health Status: Focus on Pregnant and Breastfeeding Women.

Oral health management is vital for pregnant women and their fetuses. This study analyzed the factors affecting maternal oral health status. It used secondary data obtained from the 2019 Korean Community Health Survey. Data were analyzed using SPSS 21.0 for complex descriptive statistics, independent t-test, Pearson's correlation coefficients, and multiple regression analysis. Multiple regression analysis revealed that age (ß = -0.01, p < 0.001), maternal characteristics (ß = -0.10, p < 0.001), education (ß = -0.06, p = 014), subjective health status (ß = 0.27, p < 0.001, sleep duration (ß = 0.07, p = 0.003), breakfast frequency (ß = -0.16, p < 0.001), unmet dental care needs (ß = 0.35, p < 0.001), and depression (ß = -0.02, p < 0.001) are key factors of maternal oral health status. Furthermore, oral health status is associated with mental health factors, such as depression. Therefore, the importance of maternal oral health among pregnant and breastfeeding women must be highlighted to promote the health of mothers and their babies.

The Effects of Lifestyle Interventions on the Health-Promoting Behavior, Type D Personality, Cognitive Function and Body Composition of Low-Income Middle-Aged Korean Women.

Low-income middle-aged women (LMW) who are vulnerable have various physical and psychosocial problems. They need lifestyle interventions to actively cope with these risk factors. This study used a randomized control group pretest-posttest design. LMW aged from 40 to 60 years were recruited and randomly assigned to an experimental group (n = 31) and a control group (n = 32). The lifestyle interventions for this study, which were implemented for eight weeks, included nutritional management, physical activity, stress management and cognitive function improvement based on King's goal attainment theory. The measured outcomes were health-promoting behaviors, Type D personality, cognitive function and body composition. The experimental group scored significantly higher than the control group for health-promoting behaviors (effect size (ES) = 0.68~1.27, p < 0.001~0.014) and cognitive function (ES = 0.79~1.31, p < 0.001~0.005). The negative affectivity (ES = 0.70, p = 0.012) and the prevalence of a Type D personality (x2 = 4.39, p = 0.047) and the systolic blood pressure (ES = 0.65, p = 0.019) decreased significantly in the experimental group compared with the control group. Lifestyle interventions for LMW were effective in improving health-promoting behavior, Type D personality traits and cognitive function.

Effects of a Lifestyle Intervention on Health-Promoting Behavior, Psychological Distress and Reproductive Health of Overweight and Obese Female College Students.

This study aimed to examine the effect of a lifestyle intervention (LSI) on overweight or obese female university students. Participants: A total of 53 overweight or obese female college students participated. This study was conducted from May to December 2017 in Jeonbuk Province, South Korea. A quasi-experimental design using a non-equivalent control group pretest-posttest was used. The LSI consisted of providing health information, individual health counseling, lifestyle monitoring, and effective support based on the interaction model of client health behavior, which was implemented for 12 weeks. Significant group differences were found in health-promoting behavior, psychological distress, reproductive health, body weight, body fat, and triglyceride level among participants. LSIs are effective in improving health-promoting behavior, psychological distress, reproductive health, and body composition. Therefore, healthcare providers should develop and apply LSIs through interaction for overweight or obese female college students.

Factors Influencing Quality of Life in Early Postpartum Women.

Postpartum women experience various changes in their physical and psychological health and in their relationships with their spouse and newborn. This study aimed to identify and evaluate the factors that affect the quality of life (QoL) of women within six weeks after childbirth. A prospective, cross-sectional correlational study was used. A convenience sample of 179 postpartum women was recruited from four postpartum care centers in South Korea. Participants completed structured questionnaires on postpartum fatigue, postpartum depression, marital intimacy, breastfeeding adaptation, and quality of life. Marital intimacy (ß = 0.466, p < 0.001) was the most influencing factor on the QoL of women during the postpartum period. In descending order, postpartum fatigue (ß = -0.192, p = 0.001), postpartum depression (ß = -0.190, p = 0.001), breastfeeding adaptation (ß = 0.163, p = 0.002), and occupation (ß = 0.163, p = 0.004) all had a significant influence on QoL (F = 32.09, p < 0.001), and the overall explanatory power was 63.6%. It is necessary to assess and consider the physical, psychological, relational, and demographic factors of women during the early postpartum period. Comprehensive interventions need to be developed to improve the QoL of women during the postpartum period.
