Aim: This study aimed to examine a hypothetical model of physical activity (PA) and health outcomes related to sarcopenia in women with rheumatoid arthritis (RA) based on self‐determination theory. Design: Cross‐sectional study. Methods: This study included 214 women diagnosed with RA from the outpatient rheumatology department of a university‐affiliated hospital in South Korea. Data were collected from September 2019 to August 2020 through structured questionnaires and anthropometric measurements and analysed using path analysis to test the hypothesized model. The primary health outcomes were perceived health status and sarcopenia‐related health (thigh circumference, handgrip strength and sarcopenia risk). Results: The final model's fit indices were adequate. Physical activity was directly affected by motivation for PA, while depression, self‐efficacy for PA, health care provider's autonomy support and basic psychological needs satisfaction indirectly affected PA. Physical activity directly affected perceived health status and thigh circumference, while perceived sarcopenia risk and handgrip strength were directly affected by disease activity and age. Patient or Public Contribution: Patients were involved in a questionnaire‐based survey. [ABSTRACT FROM AUTHOR]

Background: Although many studies have been conducted to examine predictors of quality of life (QoL), little information exists on the real-world application of Rector's conceptual model for QoL related to heart failure (HF). Objectives: In this study, we aimed to examine a hypothetical model of QoL based on Rector's conceptual model for QoL in relation to HF and the existing literature on patients with HF. Methods: Using a cross-sectional survey, 165 patients with HF were recruited from an outpatient clinic in Korea. Data were collected based on Rector's model constructs, such as cardiac function, symptoms, functional limitation, depression, distress, and QoL. Left ventricular ejection fraction for cardiac function was measured using echocardiography. Results: Functional limitation, depression, and distress, but not symptoms, had a direct effect on QoL (all P s <.001). Cardiac function and symptoms directly affected functional limitation (β = 0.186, P =.004, and β = −0.488, P = <.001, respectively), whereas cardiac function, symptoms, and depression affected QoL through functional limitation and distress. Conclusions: These results confirm that the Rector's model is suitable for predicting QoL in patients with HF. These findings have potential to guide and inform intervention programs designed to alleviate symptoms in patients with HF, enhance their physical functioning, and moderate their psychological distress with the ultimate goal of improving their QoL.

This study examined the psychometric properties of the Korean version of the Patient Knowledge Questionnaire-Osteoarthritis (PKQ-OA-K). A cross-sectional survey was conducted with 157 adults with osteoarthritis from the outpatient clinic at a university hospital in Korea. The overall correct answer rate for the PKQ-OA-K was 60.4%; notably, the drug therapy subscale had the lowest median score percentage (42.9%). For structural validity, exploratory factor analysis identified the PKQ-OA-K as two-dimensional, explaining 52.4% of the total variance. Confirmatory factor analysis showed that the two-factor model adequately fit the data. The PKQ-OA-K was positively correlated with education level (r = 0.24) and osteoarthritis outcomes (r = 0.17), thus verifying the hypotheses of construct validity. The intraclass correlation coefficient for test-retest reliability was 0.52; alpha was 0.44. The PKQ-OA-K has excellent validity but imperfect reliability for adults with osteoarthritis. This study recommends cautious use of the PKQ-OA-K to assess Korean patients' knowledge of osteoarthritis. [ABSTRACT FROM AUTHOR]

Purpose : This study examined factors influencing the attitudes towards nurse-led defibrillation in the emergency department (ED) and intensive care unit (ICU). Methods : This was a cross-sectional study. A total of 212 nurses in the ED and ICU from three general hospitals responded to the survey. Data were collected between September and October 2015 using structured questionnaires. Independent t-test, Mann-Whitney U test, one-way analysis of variance (ANOVA), Pearson's correlation coefficient, and hierarchical multiple regression were used to analyze factors affecting nurses' attitudes towards nurse-led defibrillation. Results : The mean score of nurses' attitudes towards nurse-led defibrillation was 61.37 of a possible 91. Hierarchical multiple regression showed that nurses' attitudes towards nurse-led defibrillation were significantly affected by their experiences regarding cardiopulmonary resuscitation ( p=.003), knowledge regarding electrocardiogram interpretation and defibrillation ( p=.007), and tenure in ED or ICU ( p=.043). Conclusion : Results indicate that employers should set policies to support nurses in maintaining their careers in the ED or ICU and conduct systematic educational programs for them. This will increase nurses' confidence in performing defibrillation, which will lead to early defibrillation during in-hospital cardiac arrest. Consequently, it can be a strategy to increase the survival rate of cardiac arrest patients. [ABSTRACT FROM AUTHOR]

Purpose: This study examined the effects of a physical activity promoting program based on the Information-Motivation-Behavioral Skills (IMB) model on physical activity and health outcomes among obese older adults with knee osteoarthritis. Methods: This study utilized a randomized controlled trial with a convenience sample of 75 obese older adults with knee osteoarthritis in a university hospital. The older adults in the intervention group participated in a 12-week program involving weekly group sessions and monitoring calls with education booklets and video clips for exercise dances, while those in the control group received an usual care. Outcomes were measured using self-report questionnaires, anthropometrics, and blood analyses. The intervention effects were analyzed using Mann-Whitney U test and ANCOVA. Results: The mean age of participants was 74.9 years with 84.0% women. The intervention group at 12 weeks showed significantly greater improvements in self-efficacy for physical activity (F=81.92, p<.001), physical activity amounts (Z=-2.21, p=.044), knee joint function (F=15.88, p<.001), and health-related quality of life (F=14.89, p<.001) compared to the control group. Among obese-metabolic outcomes, the intervention group at 12 weeks showed a significant decrease in visceral fat mass (F=7.57, p=.008) and improvement in high-density level cholesterol (F=9.51, p=.003) compared to the control group. Conclusion: Study findings support the need for an IMB based physical activity program for promoting physical activity, knee function and health outcomes in obese older adults with knee osteoarthritis. Longitudinal studies are warranted to confirm the persistence of obese-metabolic effects in clinical settings. [ABSTRACT FROM AUTHOR]

Aims and objectives: The effects of an individualised nutritional education and support programme on dietary habits, nutritional knowledge and nutritional status of 71 older adults living alone were examined. Background: Although a regular dietary meal plan is recommended for improving nutritional status of older adults living alone, little research is done in this field in Korea. Design: A pre‐ and post‐test controlled quasi‐experimental design was used at public health centres. Methods: The intervention group participated in an intensive nutritional education and support programme once a week for 8 weeks with dietary menus provided by home visiting nurses/dieticians; control group received usual care. Dietary habits and nutritional knowledge were assessed using structured questionnaires; nutritional intake status was analysed using Computer Aided Nutritional Analysis Program 5.0. Results: The mean age of participants was 77.6 years, and 81.7% of the participants were women. At 8 weeks, there were significant interactions of group by time for dietary habits, nutritional knowledge and selected nutritional status of protein, iron and vitamins of B2 and C. Changes over time in the mean score of dietary habits and nutritional knowledge were significantly improved in the intervention group compared to the control group. The percentages of normal nutrition intake of protein, iron and vitamins A and C in the intervention group were significantly higher than the control group at 8 weeks. Conclusions: Nutritional education and support programme positively impacted dietary habits, nutritional knowledge and selected nutritional status in older adults living alone, and we highlight the need for community‐based nutritional education and counselling programmes. Relevance to clinical practice: Older adults living alone in a community have relatively poor nutritional status and thus require tailored nutritional intervention according to objective nutritional analysis. It is necessary to link visiting nurses with dieticians in the community to manage effective nutritional programme continuously. [ABSTRACT FROM AUTHOR]

Aim The study purpose was to determine factors affecting aging cognitive function of 3,645 community-dwelling older adults in Korea. Methods The Hasegawa Dementia Scale assessed aging cognitive function, blood analyses and anthropometrics assessed cardio-metabolic risk factors, and the Geriatric Depression Scale Short Form Korean Version assessed depressive symptoms. Results Participants with poor aging cognitive function were more likely to be in the late age group (≥75 y) and currently smoking and have a medical history of stroke, high body mass index, and high level of depressive symptoms; they were also less likely to engage in regular meals and physical activities. Conclusion Regular meals and physical activities may be primary factors for clinical assessment to identify older adults at risk for aging cognitive function. With aging, depressive symptoms and other unhealthy lifestyle behaviours should be managed to prevent cognitive function disorders. [ABSTRACT FROM AUTHOR]

Aim To examine the mediating role of social support on the relationship of depressive symptoms to medication adherence and self-care activities in Korean adults. Background Recent evidence suggests that higher levels of social support are associated with improved medication adherence and self-care activities; however, the role of social support on the relationship of depressive symptoms to medication adherence and self-care activities is less well understood. Design A cross-sectional survey. Methods The data were collected from 311 Korean adults with type 2 diabetes who were taking hypoglycaemic agents in the period 2012-2013. Depressive symptoms, social support, medication adherence and self-care activities were assessed using structured questionnaires. Multiple regression analysis with adjustment for covariates and the Sobel test were used to examine the mediating effect of social support on the relationship of depressive symptoms to medication adherence and self-care activities. Results There were statistically significant differences by subgroups with and without depressive symptoms in social support, medication adherence and self-care activities of diet, physical activity and stress management. The Sobel test confirmed that social support mediated the effect of depressive symptoms on medication adherence and self-care activities of diet, physical activity and stress management. Conclusion The evidence from this study suggests that social support-enhancing interventions that also manage depressive symptoms may be more timely and effective than interventions that target depressive symptoms alone in promoting adherence to medication adherence and self-care activities in this population.

This study examined the prevalence of metabolic syndrome and the risk level of cardiovascular disease ( CVD) in a vulnerable population of 407 subjects in Korea. This descriptive study was a part of the Tailed Health Visiting Service Program, using baseline data from public health centres in Suwon, Korea. The definition of metabolic syndrome was based on the National Cholesterol Education Program criteria, and risk of CVD was estimated according to the Framingham study equation. This study demonstrated that the prevalence of metabolic syndrome was 40.8% higher and the risk of CVD was significantly 3.1 times higher among those with metabolic syndrome than among those without it. Of those with metabolic syndrome, 50.6% overall and 81.1% of men had a high risk for CVD. These findings suggest a need to screen and prevent the risk of CVD in vulnerable populations with metabolic syndrome. [ABSTRACT FROM AUTHOR]

This pilot study was performed to investigate the effects of a community-based intervention ( CBI) on cardio-metabolic risk and self-care behaviour in 92 older adults with metabolic syndrome at public health centres in Suwon, Korea. A prospective, pretest and posttest, controlled, quasi-experimental design was used. The older adults in the intervention group participated in an 8-week intensive lifestyle counselling, whereas those in the control group received usual care. The mean (standard deviation) age of the participants was 71.4 (4.43) years ranging from 60 to 84, and 75.0% of the participants were female. The intervention group at 8 weeks showed significant reduction in waist circumference by −1.35 cm ( P < 0.001) and improved self-care behaviour (+ 5.17 score, P < 0.05) and self-efficacy (+ 4.84 score, P < 0.001) when compared with the control group. The percentages of those who successfully completed the targeted behavioural modification were 71.7% for exercise and 52.2% for dietary control in the intervention group at 8 weeks. This pilot study provided evidence of the beneficial impact of the CBI for Korean older adults with metabolic syndrome. [ABSTRACT FROM AUTHOR]

The aims of the present systematic review were to identify currently available patient-reported outcome measures for diabetes self-care that have been psychometrically evaluated and to evaluate their measurement properties. A systematic literature review with a meta-analysis. A systematic literature search was conducted of the MEDLINE, EMBASE, and CINAHL databases. The updated COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) was applied using the following steps to evaluate the measurement properties of the diabetes self-care measures: (1) evaluating the methodological quality, (2) evaluating either quantitatively summarized or quantitatively pooled data against criteria for good measurement properties, and (3) the evaluating the quality of evidence by applying the modified Grading of Recommendations Assessment, Development, and Evaluation approach. Among 8434 articles yielded by the database search, 27 full-text articles that reported 34 studies of 13 different patient-reported outcome measures were included in this systematic review. The Diabetes Self-Management Instrument demonstrated the best content validity, with sufficient moderate-quality evidence for relevance, comprehensiveness, and comprehensibility. The Diabetes Self-Management Instrument exhibited sufficient moderate-quality evidence for structural validity and internal consistency, and sufficient high-quality evidence for convergent validity of hypothesis testing and sufficient low-quality evidence for reliability. The eight-item Summary of Diabetes Self-Care Activities–Revised was the most frequently investigated and shortest instrument with sufficient high-quality evidence for structural validity and internal consistency. However, the sufficient but very-low-quality comprehensiveness and the inconsistent very-low-quality comprehensibility for content validity, and the insufficient low-quality evidence for reliability must be considered when selecting this instrument. None of the identified diabetes self-care instruments appears to be universally superior to the others. The Diabetes Self-Management Instrument might be the best based on current evidence, but this requires further evaluation of the measurement of invariance across languages. The eight-item Summary of Diabetes Self-Care Activities–Revised is the shortest instrument, but current evidence with regards to its content validity and reliability needs to be considered before applying this instrument. Further studies are recommended to evaluate the reliability, measurement error, and responsiveness of the diabetes self-care measurements. [ABSTRACT FROM AUTHOR]
