ABSTRACT
BACKGROUND: Depressive symptoms are substantial among stroke survivors and their caregivers in poststroke management. Optimism and social support are known to protect against depressive symptoms. However, little is known about how optimism and social support contribute to depressive symptoms among stroke survivor-caregiver dyads. The study's purpose was to examine actor and partner effects of optimism on depressive symptoms through perceived social support among stroke survivors and caregiver dyads in the chronic stage of rehabilitation. METHODS: Stroke survivors and caregivers (N = 105 dyads) completed the survey at 2 years of follow-up after the first stroke. Depressive symptoms, optimism, and perceived social support were assessed using the Center for Epidemiologic Studies-Depression, the Life Orientation Test, and the Interpersonal Support Evaluation List. The Actor-Partner Interdependence Model Extended to Mediation analysis was used to test the indirect effect of optimism on depressive symptoms through perceived social support. RESULTS: Higher optimism was significantly associated with lower depressive symptoms for caregivers (direct actor effect, -0.6844; 95% confidence interval [CI], -0.9844 to -0.3844) and stroke survivors (direct partner effect, -0.4189; 95% CI, -0.0789 to -0.0889). Perceived social support availability significantly mediated the association between optimism and depressive symptoms for stroke survivors (indirect effect, -0.1957; 95% CI, -0.3923 to -0.0670). Caregiver perceived social support availability was also a significant mediator between caregivers' optimism and stroke survivors' depressive symptoms (indirect effect, 0.1658; 95% CI, 0.0559-0.3128). CONCLUSIONS: Intervention improving dyad members' optimism and social support would be beneficial to improve depressive symptoms of the stroke survivors and caregivers in chronic stroke management.
ABSTRACT
BACKGROUND: The purpose of this study was to identify patterns of depressive symptom trajectory and examine the associations of the symptom trajectory with caregiving burden, family function, social support, and perceived health status of caregivers of stroke survivors during the first year of caregiving after discharge from rehabilitation center. METHODS: Caregivers of stroke survivors completed a survey of depressive symptoms, caregiving burden, family function, perceived availability of social support, and perceived health status at postdischarge and 1 year. Patterns of depressive symptom trajectory (ie, symptom-free, symptom relieved, symptom developed, and persistent symptom groups) were identified by grouping depressive symptoms based on 2 assessments using the Center for Epidemiologic Studies-Depression. Repeated-measures analysis of variance and multinomial logistic regression were used to examine the associations. RESULTS: Of the 102 caregivers, 57.8% were symptom-free, 20.6% experienced persistent depressive symptoms, 11.8% relieved depressive symptoms, and 9.8% developed depressive symptoms. There were significant changes in family function (Wilks λ = 0.914, P = .038) and perceived health status (Wilks λ = 0.914, P = .033) among the groups during the first year of caregiving. The persistent symptom group reported the highest level of burden and the lowest level of family function and perceived availability of social support at both assessment times. Compared with symptom-free caregivers, caregivers with persistent depressive symptoms were 7 times more likely to have fair/poor health rather than excellent/very good health at 1 year (odds ratio, 7.149; P = .012). CONCLUSION: Caregivers with persistent depressive symptoms are the most vulnerable to negative psychosocial outcomes and poor perceived health status during the first year of caregiving from discharge for stroke survivors.

BACKGROUND: Patients with heart failure (HF) and their family caregivers usually consume similar diets, but there is a lack of evidence about diet quality of patients with HF and their family caregivers. OBJECTIVE: The specific aim of this study was to compare diet quality of patients with HF with that of their family caregivers. METHODS: In this cross-sectional study, 40 patients with HF and their 40 family caregivers completed a VioScreen Food Frequency Questionnaire from which Healthy Eating Index-2010 (HEI) diet quality scores (consisting of the total HEI score and 12 component scores) were calculated. RESULTS: None of the 40 patient-caregiver dyads had a high diet quality score (ie, total HEI > 80), whereas 21% of participants had poor diet scores (ie, total HEI ≤ 50). There were no differences in total HEI scores (58.5 vs 59.4, P = .58) or the 12 component scores of the HEI within dyad members. Mean scores of 6 of the 12 components (ie, total fruit, greens and beans, total protein foods, seafood and plant proteins, fatty acids, empty calories) for both members of the HF dyad were lower than the national average. Interestingly, scores for the sodium component were similarly low in patients and caregivers (4.1 vs 3.4, P = .24), indicating high sodium intake. CONCLUSION: Both patients and caregivers consume poor-quality diets that are high in sodium. These findings suggest that nutrition interventions to improve diet quality for patients with HF need to be targeted at the family as a unit.

BACKGROUND: Chronic kidney disease (CKD) is a progressive and lifelong condition with multiple medical comorbidities. Patients with CKD experience frailty more frequently and have lower health-related quality of life than do those with other chronic diseases. The purpose of this study was to examine the prevalence of frailty and investigate the contribution of frailty to quality of life in pre-dialysis CKD patients in Korea. METHODS: Using a cross-sectional survey design, data were collected at an outpatient CKD clinic in a general hospital in Korea. The frailty criterion was modified from previous studies. The Short Form-36 Health Survey version 2 was used to measure physical and mental component summary scores. Data were analyzed using chi-square, t-tests, and hierarchical linear regression. RESULTS: Of the 168 CKD patients, 63 (37.5 %) were frail. Frail patients were significantly older and had lower physical and mental quality of life than those who were non-frail. In hierarchical regression evaluating the influence of frailty on physical and mental quality of life, the initial model was significantly improved when frailty was included. Frail patients had lower physical and mental quality of life. CONCLUSIONS: Frailty affected both physical and mental quality of life in pre-dialysis patients with CKD. More attention should be paid to the potential role of early detection and prevention of frailty to improve patients' quality of life.

Smoking is a major risk factor for not only the occurrence of myocardial ischaemia but also recurrences of vascular stenosis. This study aimed to evaluate health-promoting lifestyles and abstinence rate after a smoking cessation programme. Sixty-two smokers who had undergone percutaneous coronary intervention were randomly assigned to either the experimental or control group. The experimental group (n = 30) received 10 phone counselling sessions and 21 short message service messages for abstinence and coronary disease prevention, whereas the control group (n = 32) received only the standard education. After the intervention, 14 members of the experimental group had switched to a non-smoking status, confirmed biochemically; moreover, their physical activity and stress management scores increased significantly. However, self-efficacy of smoking cessation was not reflected in the cotinine levels. Thus, it is necessary not only to increase self-efficacy but also to determine the factors that affect the success of smoking cessation so that they can be included in the intervention. Our results suggest that phone counselling and short message service messaging might be important tools for the realization of smoking cessation and lifestyle changes among patients who have undergone percutaneous coronary intervention.

PURPOSE: This study was conducted to identify the relationship between symptom clusters and quality of life (QOL) in patients with stages 2 to 4 chronic kidney disease (CKD) in Korea. METHODS: Using self-reported questionnaires, data were collected from 143 patients who underwent treatment for CKD at one hospital in Korea. The 17-item Patient Outcome Scale was used to measure symptoms, and the 36-item Short Form Health Survey Instrument Version 2 (SF-36v2) was used to measure the QOL. Data were analyzed using factor analysis to draw symptom clusters. RESULTS: Among five symptom clusters, the energy insufficiency and pain cluster was found to have the highest prevalence and greatest severity. The severity of symptom clusters showed negative correlations with both physical and mental component summary (PCS and MCS) scores. Elderly patients scored low on PCS, whereas younger patients in their 30s and 40s scored low on MCS. Negative correlations were found between symptom clusters and PCS as well as MCS. The severity of symptoms and QOL had stronger relationships with subjective perception of symptoms and psychological factors than with objective clinical indicators. CONCLUSION: As the effects of physical and psychological symptoms on the QOL in patients with stages 2 to 4 CKD were identified in this study, nurses should develop strategic nursing plans focused on symptom clusters and patients' subjective perception of symptoms rather than objective clinical indicators in order to improve the QOL in patients with CKD.

This study was conducted to identify mental health status, post-traumatic stress disorder (PTSD), and psychophysiological change in female North Korean refugees. Data were collected using questionnaires and symptom checklists that measured PTSD and the psychosomatic state of the subjects. As many as 97 subjects, who had settled in and around Seoul, South Korea, were selected by snowball sampling. Mental health and PTSD levels of the participants were above a moderate level. We conclude that health care professionals need to provide female North Korean defectors with services to improve mental health and make the sociocultural transition successfully.

In this study, learner satisfaction was described, and factors influencing satisfaction with team-based learning were identified. This was a cross-sectional, descriptive survey study. Two separate 2 h team-based, learning sessions, consisting of preparation, readiness assurance, and application, were given to a cohort of 139 second year nursing students in 2010 and 263 students in 2011, respectively. At the end of the learning sessions, participants completed a self-administered questionnaire regarding their learning experience. Nursing students were generally satisfied with team-based learning. Multiple regression analysis revealed that the learning process significantly affected learner satisfaction compared to pre-assignment, course content, peer evaluation, and team activity. According to these results, team-based learning facilitators should organize and conduct team-based learning activities, while also considering instructional design factors, to help students learn effectively.

AIM: To determine women's perceived personal and comparative risks of breast cancer, and to examine the relationships with risk factors. BACKGROUND: Despite the increasing incidence of breast cancer in younger women and the availability of screening, women's health behaviors have not advanced accordingly. METHODS: A cross-sectional survey design utilized a convenience sample of 222 women in their 30s and 40s recruited from community settings in Seoul. Self-administered questionnaire data were analyzed by descriptive statistics, the chi-squared test, and ANOVA. RESULTS: Risk perception levels differed significantly by breast cancer risk factors. Half of the women were optimistic about their breast cancer risk, while perceived personal risk did not reflect women's own risk factors and comparative risk differed only by the practice of clinical breast exam. CONCLUSIONS: Women's knowledge and awareness of their breast cancer risk factors need to be improved for appropriate risk perception and health behaviors, and accurate risk estimation could be utilized to educate them in clinical settings.

We identified how the health of the growing Korean-Chinese (KC) female immigrant population differed from comparable domestic women. Using propensity score matching, we selected 227 women recruited from Korea and China; perceived health status, female cancer screening behaviors, and the Health Promoting Lifestyle Profile II were investigated. The KC women in Korea had the lowest levels of physical and mental health as well as health promoting lifestyles, but performed female cancer screenings better than other women. Considering their vulnerability, the hosting country should provide accessible health services at reasonable fees for KC women in Korea to enhance their health.

BACKGROUND: Community health workers (CHWs) have strong potential for conducting health initiatives in vulnerable countries. Their continuing activities are essential for positive outcomes. The purpose of this study is to understand CHW activities in Kyrgyzstan migrant villages and their impact on individuals and communities. METHODS: This study used a mixed-method design. All active CHWs were invited to participate in the survey and the first reflection note regarding their experience and satisfaction with CHW activities. Respondents who agreed to participate in the second reflection notes wrote additional reflection notes. Participatory observational CHW activity report meeting data was collected for additional qualitative analysis. Quantitative data were analyzed using descriptive statistics, and qualitative data were analyzed thematically. RESULTS: CHWs started their activities with altruistic and personal motives, such as social recognition and knowledge acquisition. Job-related satisfaction after the activity tended to be high. After performing home visits and resident participatory events, they experienced intrinsic motivation, resource mobilization efforts, increased autonomy, and social recognition. Although the material rewards were small as volunteers, they recognized their positive impact on individuals and communities and gained pride and happiness. CONCLUSIONS: CHWs participating in health promotion projects had training and CHW-nurse network activities and were gradually empowered in the process. When considering the sustainability of CHW activities, it is important to increase self-confidence and strengthen social recognition through empowerment.

AIM: This study was aimed at investigating the level of patient activation, and its association with self-care behaviours in older people with heart failure. DESIGN: Cross-sectional secondary data analysis was conducted. METHODS: We included a total of 182 Korean patients with heart failure who were aged ≥65 years for a cardiovascular outpatient clinic visit. Baseline characteristics, the Patient Activation Measure (PAM), health literacy, disease knowledge and self-care behaviours were collected via a self-administered questionnaire. RESULTS: The proportion of patient activation at Levels 1 and 2 was 22.5% and 14.3%, respectively. Highly activated patients had a high level of health literacy, disease knowledge and self-care behaviours. After adjusting for confounding factors, we observed that patient activation was the only statiscally significant predictor of self-care behaviours among older people with heart failure. Healthcare professionals should help patients take active roles in their self-care through a comprehensive needs assessment including health literacy and disease knowledge.

BACKGROUND: The COVID-19 pandemic has created devastating health, social, economic, and political effects that will have long-lasting impacts. Public health efforts to reduce the spread of COVID-19 are the priority of national policies for responding to the pandemic globally. Public health and social measures (PHSMs) have been shown to be effective when used alone or in combination with other measures, reducing the risk of spreading COVID-19. However, there is insufficient evidence on the status of compliance with PHSMs in the general population for the prevention of COVID-19 in public areas, including Korea. OBJECTIVE: The aim of this study was to assess levels of compliance with the recommended PHSMs against SARS-CoV-2 infection and their predictors among the general population by using national data. METHODS: This study was a secondary data analysis of the National Survey of Infectious Disease Preventive Behaviors in Community, which was conducted by the Korea Centers for Disease Control and Prevention Agency (KDCA) between October 12 and October 30, 2020. The primary study was cross-sectional, using stratified sampling via an adjusted proportional allocation method to select representative samples and ensure the stability of samples. The data were collected through phone interviews conducted by trained enumerators using a structured questionnaire. PHSM adherence was measured using a 10-item comprehensive infectious disease prevention behavior (CIDPB) scale, and each sociocognitive factor, including perceived susceptibility to SARS-CoV-2 infection, perceived severity of SARS-CoV-2 infection, perceived confidence in performing preventive behaviors related to COVID-19, information comprehension ability, and trust in information from the KDCA, was measured. A total of 4003 participants were included in the final analysis. Tobit regression and a decision tree analysis were performed to identify the predictors of preventive measures and the target groups for intervention. RESULTS: We discovered that women scored 1.34 points higher on the CIDPB scale than men (P<.001). Compared to the group aged 19 to 29 years, those aged 50 to 59 years and those older than 60 years scored 1.89 and 2.48 points higher on the CIDPB scale (P<.001), respectively. The perceived severity of infection, confidence in preventive behaviors, information comprehension ability, and trust in information from the KDCA were significant positive determinants of CIDPBs (P<.001). The perceived susceptibility to infection showed a significant negative relationship with CIDPBs (P<.001). CONCLUSIONS: Female sex, older age, lower income, and sociocognitive factors were found to be significant determinants of adhering to PHSMs. The findings suggest the need for tailored interventions for target groups; specifically, the age group that was the most active at work indicated the highest potential to spread infection. Adequate public health education and health communication for promoting adherence to PHSMs should be emphasized, and behavior change strategies for those with low perceived confidence in performing PHSMs should be prioritized.

AIM: This paper is a report of a comparison of advice on lifestyle given by healthcare providers and subsequent action by recipients between Korean Americans and native Koreans with hypertension. BACKGROUND: High blood pressure is controllable by having a healthy lifestyle, such as weight control, dietary change, exercise, low-sodium diet, alcohol restriction and smoking cessation, and by taking medication. Healthcare providers play an important role in teaching individuals with hypertension on healthy lifestyles. METHOD: This descriptive comparative study was conducted with a convenience sample of 100 Korean Americans and 100 native Koreans with hypertension. They were interviewed between May 2003 and June 2004 on the advice they received from healthcare providers on lifestyle and their subsequent action in terms of taking medication, weight control, dietary change, exercise, low-sodium diet, smoking cessation, alcohol restriction and tension reduction. Nutrient profiles were examined using the 24-hour dietary recall method. FINDINGS: Korean Americans received advice on lifestyle less than did native Koreans, but more Korean Americans followed healthy lifestyle advice on dietary change and exercise than did native Koreans (P<0.001). Weight control was the least adhered to behaviour among the Korean Americans, although almost two-thirds of them were overweight or obese. Both groups exceeded the Dietary Reference Intakes of sodium, but perceived their sodium consumption as low. CONCLUSION: Native Korean participants need to pay closer attention to carrying out the advice, whereas healthcare providers to Korean Americans need to give more advice on culturally acceptable healthy lifestyles, particularly on dietary changes and weight control. Both groups need to monitor their sodium intake more realistically. It is not only advice from healthcare providers that is integral to control of hypertension, but also that patients should follow that advice.

Despite over 10 years of support from government health programs and health organizations, children in migrant villages in Kyrgyzstan remain a public concern owing to high incidence rates of preventable diseases such as anemia. An effective community health promotion program is needed but there is a lack of knowledge of community barriers and health factors affecting children's health in these migrant villages. The purpose of this study was to conduct a community health needs assessment to develop strategies for a child health promotion program in these migrant villages. This study conducted using a mixed method that included literature review, reginal statistics, focus group and key person interviews, and a community survey. The analysis method was descriptive statistics for the questionnaires, and content analysis for the interviews. Results showed the following priorities for child health promotion: strengthening health care provider capacity, overcoming resource shortages, managing child health and preventable diseases, improving public hygiene, promoting a healthy lifestyle, and empowering school health. The strategies were identified: capacity building of health workers, increasing community participation and raising child health awareness, and supporting child health promotion services. These findings will help guide the implementation of a child health promotion program.

Atrial fibrillation (AF) is a common cardiac arrhythmia associated with poor health-related quality of life (HRQoL). However, the factors influencing HRQoL in patients with AF are not well understood. The purpose of integrative review was to investigate the factors affecting HRQoL in patients with AF based on the six domains of Ferrans and colleagues' HRQoL model. A total of 23 relevant articles published between January 2000 and March 2018 were identified using four databases and analyzed in this study. Our review showed that the HRQoL in patients with AF was consistently lower than both healthy individuals and patients with other cardiovascular diseases. The most common factor associated with HRQoL in patients with AF was anxiety-specific to AF in the symptoms domain, followed by frequency and severity of symptoms and the New York Heart Association functional class. This study highlights that monitoring and assessing patients' symptoms is vital for improving HRQoL in patients with AF. Disease-specific and cross-culturally validated tools can allow healthcare professionals to provide tailored interventions for patients with AF.

PURPOSE: Children in migrant villages in Kyrgyzstan have a high incidence of anemia and need effective health promotion programs. The purpose of this study was to evaluate a pilot study of a health promotion project for infants and toddlers based on community participation. METHODS: This was a retrospective study conducted to evaluate the effectiveness of the project. The project was carried out by nurses at a public health center, community health workers, and local residents in a migrant village. After the operational system of the project was established, health assessments, child-care education, provision of vouchers for iron supplements, and activities to improve residents' awareness were conducted during 6 months among 100 children, of whom 85 were finally analyzed. RESULTS: In international health projects, close cooperation of the project team with community residents and health workers is important. Access to the community-based program was feasible in the socially and economically poor migrant village, and improvements were shown in children's anemia and awareness of health care. CONCLUSION: By focusing on the effective aspects of this preliminary project, plans to utilize community health workers and promotion strategies can be added to the main project to improve health promotion among children in this area.
ABSTRACT
BACKGROUND: Recently, despite the high prevalence of fatigue in patients, there is a lack of research on the quality of life (QoL) in unexplained fatigue patients, indicating that they are not properly diagnosed and treated. The aim of this study was to compare fatigue severity and QoL between patients with explained and unexplained fatigue. METHODS: The study consisted of 200 Korean adults who complained of fatigue without underlying disease. Fatigue Severity Scale, Short Form Health Survey-36 version 2 (SF-36v2), and Beck Depression Inventory-II (BDI-II) self-questionnaires were administered. Participants were dichotomized to two groups, namely, patients with unexplained or explained fatigue, sorted according to laboratory examination results. The chi-square test, t-test, and Wilcoxon rank-sum test were used, and analysis of covariance was calculated after adjusting for age, sex, body mass index, smoking status, and physical component summary (PCS) of SF-36v2 or BDI-II. RESULTS: PCS of SF-36v2 between the two groups showed significant difference. Compared to patients with explained fatigue, those with unexplained fatigue showed lower physical component scores of QoL. CONCLUSION: QoL of patients with unexplained fatigue could largely diminish than those with explained fatigue. The primary clinician should be aware of poor QoL in patients with unexplained fatigue to identify who is in need of more attention and intervention.
ABSTRACT
BACKGROUND: Nursing intervention studies often suffer from a selection bias introduced by failure of random assignment. Evaluation with selection bias could under or over-estimate any intervention's effects. PS matching (PSM) can reduce a selection bias through matching similar Propensity Scores (PS). PS is defined as the conditional probability of being treated given the individual's covariates and it can be reused to balance the covariates of two groups. PURPOSE: This study was done to assess the significance of PSM as an alternative evaluation method of nursing interventions. METHOD: An intervention study for patients with some baseline individual characteristic differences between two groups was used for this demonstration. The result of a t-test with PSM was compared with a t-test without matching. RESULTS: The level of HbA1c at 12 months after baseline was different between the two groups in terms of matching or not. CONCLUSION: This study demonstrated the effects of a quasi-random assignment. Evaluation using PSM can reduce a selection bias impact that affects the result of the nursing intervention. Analyzing nursing research more objectively to reduce selection bias using PSM is needed.
