Factors affecting weight management in overweight or obese diabetic patients: the 2018-2021 Korea national health and nutrition examination survey.

PURPOSE: Diabetes is a chronic metabolic disease that affects approximately 422 million people worldwide and leads to the death of 1.5 million people every year. The prevalence of diabetes among the population aged 30 or older in Korea has steadily increased since 2018, reaching 16.7% in 2020, with one in six adults having diabetes. This study was conducted to identify factors affecting weight management in overweight or obese patients with diabetes (OOPD) in Korea using data from the 2018-2022 National Health and Nutrition Examination Survey. Therefore, the goal of this study is to analyze weight perception and factors related to weight perception and to identify factors that influence weight loss efforts among OOPD in Korea. METHODS: Socioeconomic characteristics, disease morbidity, weight perception, and weight loss efforts were investigated in 950 participants. Data were analyzed using descriptive statistics, cross-tabulation, and logistic regression. RESULTS: Among the overweight or obese patients with diabetes, 24.4% perceived their weight to be normal, with a higher proportion among men (29.6%) than among women (14.6%). Weight loss efforts were 5.11 times (95% CI: 3.02-8.66) higher in people with overweight perceptions than in those with normal weight perceptions. Additionally, the rate was 1.54 times (95% CI: 1.06 2.25) higher in people with dyslipidemia than in those without dyslipidemia. CONCLUSION: These results suggest that weight management approaches for overweight or obese patients with diabetes should be designed individually based on weight perception and disease morbidity.

The Impact of Resilience on Post-Traumatic Growth among Nurses in COVID-19-Designated Hospitals: The Mediating Effect of Meaning in Life.

This study aimed to confirm the relationship between resilience, meaning in life, and post-traumatic growth (PTG) among nurses during the COVID-19 pandemic. In particular, the mediating effect of meaning in life on the relationship between resilience and PTG was examined. A cross-sectional descriptive research design was used. The participants were 220 nurses at COVID-19-designated hospitals in Seoul. Descriptive statistics, a t-test, ANOVA, Pearson's correlation coefficient analysis, hierarchical regression, and SPSS PROCESS macro (Model 4) were used for data analyses. As a result of the study, resilience and meaning in life each had a significant positive effect on PTG. In addition, the indirect effect of meaning in life was significant, suggesting that meaning in life partially mediated the relationship between resilience and PTG. The results indicate that nurses' resilience directly contributes to the improvement of PTG, and this relationship is further strengthened indirectly through the presence of meaning in life. Therefore, it is suggested that strategies should be developed to enhance resilience and promote a sense of meaning in the profession in order to support the mental health and foster growth among nurses.

Association between serum creatinine levels and pulmonary function of Korean adults: the 2016-2019 Korea National Health and Nutrition Examination Survey.

PURPOSE: Research on the interaction between renal and lung functions has been conducted; however, studies on the general adult population are limited. This study aimed to investigate the association between serum creatinine levels and pulmonary function in Korean adults. METHODS: From the 2016-2019 Korean National Health and Nutrition Examination Survey, we recruited 11,380 participants who were 40 years or older for this study. Serum creatinine levels were divided into three groups: low, normal, and high. Pulmonary function was divided into three groups: normal, restrictive, and obstructive. The odds ratios for abnormal pulmonary function patterns were calculated using weighted multinomial logistic regression analysis. RESULTS: The odds ratios were 0.97 for low vs. normal (0.40-2.33) and 2.00 for high vs. normal (1.18-3.38) for the restrictive pattern, and 0.12 for low vs. normal (0.02-0.49) and 1.74 for high vs. normal (0.90-3.35) for the obstructive pattern after being adjusted for age, sex, smoking status, alcohol consumption, regular exercise, body mass index, diabetes mellitus, hypertension, cardiovascular disease, total energy, and total proteins. CONCLUSION: High serum creatinine levels were associated with an increased odds ratio for restrictive and obstructive pulmonary function patterns. The odds ratio of the restrictive pattern was higher than that of the obstructive pattern. Screening for abnormal pulmonary function in individuals with high serum creatinine levels may be useful to ensure that there is no abnormal pulmonary function before the onset of potential pulmonary problems. Thus, this study highlights the relationship between renal and pulmonary function using serum creatine levels, which can be easily tested in the primary medical environment of the general population.

Psychological Intervention to Promote Resilience in Nurses: A Systematic Review and Meta-Analysis.

Nurses primarily focus on caring for others, but they also require care and support to enhance their own resilience. Thus, this study aims to determine the effects of psychological interventions on nurses' resilience support and to define the influence of moderating variables that can affect these effects. The literature search was conducted in 10 electronic databases, and 5 randomized controlled trials and 10 non-randomized controlled trials were finally selected for analysis (a total of 852 participants). Statistical analyses of the effect sizes and homogeneity of the intervention programs were conducted using RevMan 5.3 from the Cochrane Library and the R program. Publication bias in the retrieved studies was tested using contour-enhanced funnel plots. The meta-analysis found that psychological interventions were effective in improving nurses' resilience immediately after the intervention (SMD = 0.59, 95% CI 0.31 to 0.86, Z = 4.18, p < 0.001) and in the short term within three months (SMD = 1.52, 95% CI 0.74 to 2.31, Z = 3.80, p < 0.001). Interventions using emotion regulation, relaxation, and self-compassion were particularly effective, and the intervention period was effective in both a short period of 1 day and a long period of more than 12 weeks. In addition, the optimal one-session time was 121-150 min, and offline interventions were more effective than online interventions. Furthermore, the effect size was affected by the intervention time for one session (QB = 12.02, df = 3, p = 0.007) and the on/offline intervention method (QB = 5.85, df = 1, p = 0.015). These findings may inform the development of targeted interventions and resilience support systems for nurses. However, in the future, more rigorous studies, such as randomized controlled trials, should be conducted to ensure strict control over the variables and to establish a stronger evidence base for the effectiveness of these interventions.

Effects of Resistance Training on C-Reactive Protein and Inflammatory Cytokines in Elderly Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Chronic low-grade inflammation that accompanies aging is associated with adverse health outcomes and may exacerbate the severity of infectious disease such as COVID-19. Resistance training (RT) has the potential to improve chronic low-grade inflammation, but the evidence remains inconclusive. This study evaluated the effects of RT on chronic low-grade inflammation in elderly adults. MEDLINE, EMBASE, Cochrane Library, CINAHL, RISS, NDSL, and KoreaMed were searched. We included studies that assessed the effect of RT on C-reactive protein (CRP), interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-α in those aged ≥60 years. The effect size was estimated using fixed or random-effects models. Subgroup analysis was performed regarding age, health status, training method, number of exercises, intensity, weekly frequency, and duration. In the 18 randomized controlled trials (539 patients) included, RT was effective in alleviating CRP (effect size = −0.72, 95% confidence interval = −1.06 to −0.38, p < 0.001), IL-10 (−3.34, −6.16 to −0.53, p = 0.02), and TNF-α (−0.56, −1.08 to −0.03, p = 0.04) in elderly adults and tended to reduce IL-6 (−0.59, −1.18 to 0.00, p = 0.05). Subgroup analyses showed CRP reduction regardless of age, training method, number of exercises, intensity, weekly frequency, and duration. RT can be used to ameliorate chronic low-grade inflammation in elderly adults.

Psychological Effects of Online-Based Mindfulness Programs during the COVID-19 Pandemic: A Systematic Review of Randomized Controlled Trials.

(1) Background: The COVID-19 outbreak has caused psychological problems worldwide. This review explored the psychological effects of online-based mindfulness programs during the COVID-19 pandemic. (2) Methods: This systematic review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials that were published in the English language from 1 January 2020 to 31 May 2021 on online-based mindfulness programs for psychological problems due to the COVID-19 pandemic were searched in electronic databases. Quality assessment was conducted on the retrieved RCTs using the Cochrane risk of bias tool for RCTs. (3) Results: Six RCTs were included in this review. Quality appraisal of included RCTs ranged from 1 for low risk of bias to 5 for high risk of bias. There is evidence from the six RCTs that online-based mindfulness interventions may have favorable effects for reducing the levels of psychological problems, such as anxiety, depression, and stress. (4) Conclusions: Online-based mindfulness programs may be used as complementary interventions for clinical populations, healthy individuals, and healthcare workers with psychological problems due to the COVID-19 pandemic.

Effects of yoga on immune function: A systematic review of randomized controlled trials.

OBJECTIVE: This systematic review attempts to confirm the added evidence to assess the effect of yoga on immune function. METHODS: The Cochrane Library, Embase, PsycINFO, PubMed, and Web of Science electronic databases were searched according to the PRISRMA method to identify randomized controlled trials (RCTs) on the immunological effects of yoga published in the English language from January 1, 2017, to December 31, 2020. This review could only be descriptively summarized because of heterogeneity of the included RCTs. RESULTS: Eleven potential trials were identified and included in this review. Quality appraisal of included trials ranged from 3 for unclear risk of bias and 8 for high risk of bias. There is evidence from 11 RCTs that yoga may have favorable effects for reducing the levels of anti-inflammatory markers. CONCLUSIONS: Yoga may be used as a complementary intervention for clinical populations or healthy individuals.

The Effects of Advance Care Planning on Decision Conflict and Psychological Distress: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Purpose: Advance care planning (ACP) is widely understood to improve end-of-life care. This systematic review and meta-analysis aimed to examine the effects of ACP interventions on decision conflict and psychological distress. Methods: A search of PubMed, CINAHL, CENTRAL, EMBASE, KISS, KoreaMed, and RISS was conducted in November 2020. The study included randomized controlled trials. Data were pooled using fixed- and random-effects models. Results: Fourteen studies were identified that cumulatively included 1,548 participants. ACP interventions were effective in alleviating decision conflict (d=-0.53; 95% CI -0.83 to -0.23), depression (d=-1.22; 95% CI -1.71 to -0.74) and anxiety (d=-0.76; 95% CI -1.12 to -0.39). Conclusion: ACP interventions have significant positive effects on reducing decision conflict and psychological distress. A high level of bias was shown related to allocation concealment and blinding. The results of this study are expected to be useful for end-of-life care providers to improve the effectiveness of ACP interventions.

A Study on the Motivations of Korean Hospice Volunteers.

AIM: Volunteers play a key role in hospice and palliative service. This study was performed to investigate the motivations of Korean hospice volunteers and to identify the predictors that affect their service period. MATERIALS AND METHODS: The accomplished questionnaire sheets of 93 subjects were included in the analysis. Inventory of Motivations for Hospice Palliative Care Volunteerism to measure the motivations of the hospice volunteers was used. The collected data were subjected to a statistical analysis of the mean and standard deviation, a t-test, and multinomial logistic regression analysis. RESULTS: The motivation score of the hospice volunteers in South Korea is 75.57 ± 10.97, and the top three in the motivation list were altruism, civic responsibility, and self-promotion. Among the subdomains, altruism, 1-4-year working experience (B = 0.79, standard error (SE) = 0.26, P = 0.002, Exp (B) =0.45), and more than 10-year working experience (B = 1.00, SE = 0.30, P = 0.001, Exp (B) =0.36) had statistically significant influences. CONCLUSIONS: The finding of this study can be used as basic information for the recruitment and management of hospice volunteers in South Korea.

[Purpose] This study performed an effect-size analysis of massage therapy for shoulder pain. [Subjects and Methods] The database search was conducted using PubMed, CINAHL, Embase, PsycINFO, RISS, NDSL, NANET, DBpia, and KoreaMed. The meta-analysis was based on 15 studies, covering a total of 635 participants, and used a random effects model. [Results] The effect size estimate showed that massage therapy had a significant effect on reducing shoulder pain for short-term efficacy (SMD: -1.08, 95% CI: -1.51 to -0.65) and for long-term efficacy (SMD: -0.47, 95% CI: -0.71 to -0.23). [Conclusion] The findings from this review suggest that massage therapy is effective at improving shoulder pain. However, further research is needed, especially a randomized controlled trial design or a large sample size, to provide evidence-based recommendations.

Effects of Combined Foot Massage and Cognitive Behavioral Therapy on the Stress Response in Middle-Aged Women.

OBJECTIVE: Several intervention studies have suggested that foot massage and cognitive behavioral therapy (CBT) are beneficial for reducing the stress response. However, no randomized control trials have been conducted to examine these effects in middle-aged women, who are more commonly exposed to stress relative to others. This study aimed to examine the effects of combined self-administered foot massage and CBT on the psychophysiological stress response in Korean middle-aged women. DESIGN: Randomized controlled trial. SETTING: Subjects were recruited from the social welfare center in Sahmcheok, Kangwondo, Korea. The subjects performed some of the massage at the center and some at home, and CBT was performed at the center. SUBJECTS: Fifty-three women aged 45-64 years were randomly assigned to Group A (intervention, n = 31) or B (usual care, n = 30). INTERVENTION: Combined self-administered foot massage and CBT. OUTCOME MEASURES: Depression, anxiety, stress, blood pressure, heart rate, blood glucose (BG), and oxygen saturation were measured at baseline and 3-week follow-up. RESULTS: Mean depression scores (p = 0.021), stress scores (p = 0.009), systolic blood pressure (SBP) (p = 0.035), and BG levels (p = 0.007) had decreased significantly subsequent to the intervention. CONCLUSION: Combined self-administered foot massage and CBT led to reductions in depression, stress, SBP, and BG levels. Therefore, the intervention could be an effective means of reducing the stress response in middle-aged women.

Effects of a 10-Day Intensive Health Promotion Program Combining Diet and Physical Activity on Body Composition, Physical Fitness, and Blood Factors of Young Adults: A Randomized Pilot Study.

BACKGROUND A lifestyle characterized by poor eating habits and physical inactivity is a risk factor for multiple lifestyle diseases in young adults. This study assessed the effects of implementing an intensive 10-day health promotion program combining diet and physical activities on body composition, physical fitness, and biochemical parameters of young adults. MATERIAL AND METHODS In this randomized pilot study, 30 female undergraduate students were randomly allocated to an intervention and a control group. The health promotion program consisted of unlimited amounts of vegetarian food; aerobic, flexibility, and strength exercises (3 hours/day); lectures on health (3 hours/day); massage practice (2 hours/day); and healthy cooking practice (1 hour/day). The effects of the intervention were analyzed using the Mann-Whitney U test and the Wilcoxon signed-rank test. RESULTS The intensive 10-day health promotion program significantly reduced body weight, body mass index, triglyceride, total cholesterol, low-density lipoprotein cholesterol, blood glucose, and the homeostasis model assessment of insulin resistance. At the same time, participants demonstrated increased back muscle, leg muscle, and grip strength; waist and shoulder flexibility; balance; and cardiorespiratory endurance. CONCLUSIONS The intensive 10-day health promotion program is a viable intervention for improving body composition, physical fitness, glycemic control, and blood lipid levels in young adults.

Effectiveness of massage therapy on the range of motion of the shoulder: a systematic review and meta-analysis.

[Purpose] This study was conducted to identify and analyze the degree of effect of massage therapy on the range of motion of the shoulder. [Subjects and Methods] The database search was conducted using PubMed, CINAHL, Embase, PsycINFO, RISS, NDSL, NANET, DBpia, and KoreaMed. The meta-analysis was based on 7 studies, covered a total of 237 participants, and used a random-effects model. [Results] The effect size estimate showed that massage therapy significantly improved the shoulder range of motion, especially the flexion (SMD: 18.21, 95% CI 1.57-34.85) and abduction (SMD: 22.07, 95% CI 5.84-38.30). [Conclusion] The review findings suggest that massage therapy is effective in improving the shoulder flexion and abduction.

Effects of manual lymph drainage for abdomen on the brain activity of subjects with psychological stress.

[Purpose] The present study investigated the effects of manual lymph drainage for abdomen on electroencephalography in subjects with psychological stress. [Subjects and Methods] Twenty-eight subjects were randomly allocated to undergo a 20-min session of either manual lymph drainage or abdominal massage on a bed. [Results] Analysis of electroencephalograms from the manual lymph drainage group showed a significant increase in relaxation, manifested as an increase in average absolute, relative alpha activity and a decrease in relative gamma activity. [Conclusion] Our results suggest that the application of manual lymph drainage from the abdomen provides acute neural effects that increase relaxation in subjects with psychological stress.

Preventive effects of stretching and stabilization exercises on muscle fatigue in mobile phone users.

[Purpose] The purpose of this study was to investigate the preventive effects of stretching and stabilization exercises on muscle fatigue of the neck erector spine and upper trapezius muscles. [Subjects and Methods] The subjects of this study were 26 healthy university students (14 males and 12 females). Each subject was assigned randomly to each of three study groups in order to prevent order effect. The three groups included in this study were the no-exercise, stretching exercise, and neck stabilization exercise groups. The median electromyographic frequency was used as a gauge of muscle fatigue. [Results] Decreased muscle fatigue was demonstrated by an increase in the median electromyographic frequency values in all the four muscle groups in the comparison between conditions 1 and 3. In particular, statistically significant differences were found between the two conditions in the right upper trapezius muscle group. [Conclusion] These findings suggest that the effect of stretching and stabilization exercises can reduce muscle fatigue in mobile phone users.

Effects of Psychosocial Interventions for School-aged Children's Internet Addiction, Self-control and Self-esteem: Meta-Analysis.

OBJECTIVES: This study was conducted to perform an effect size analysis of psychosocial interventions for internet addiction and to identify the intervention moderators applied to school-aged children. METHODS: For the meta-analysis, studies were included that were published in English or Korean until January 2015, without limitation in terms of the year. They were retrieved from 11 electronic databases and by manual searches according to predefined inclusion criteria. RESULTS: A total of 37 studies were selected, which included 11 treatment conditions and covered a total of 1,490 participants. The effect size estimates showed that psychosocial interventions had a large effect for reducing internet addiction (standardized mean difference [SMD], -1.19; 95% confidence interval [CI], -1.52 to -0.87) and improving self-control (SMD, 0.29; 95% CI, 0.11 to 0.47) and self-esteem (mean difference, 3.58; 95% CI, 2.03 to 5.12). The moderator analyses reveals that group treatments, a selective approach, a long duration, a community setting, or higher school grade had a larger effect. CONCLUSIONS: The findings of this review suggest that psychosocial intervention may be used to prevent Internet addiction in school-aged children, although further research should be conducted using a randomized controlled trial design or diverse age groups to provide evidence-based recommendations.

Development and evaluation of an education program for professional palliative care nursing.

PURPOSE: This study aimed to develop a "Palliative Care Professional" education program and evaluate its effects on the recognition of good death, palliative care, and the meaning of life for nurses. METHODS: It was developed based on the hospice care program for volunteers being used in the Hospice Palliative Care Research Center of S University in Seoul. It was also based on the studies which investigated the educational needs of nurses in palliative care. This program consisted of 5 sessions and 16 content items for 2 weeks. A non-equivalent control group non-synchronized design was utilized and participants were assigned to the experimental group (n=42) or the control group (n=44). RESULTS: The recognition of a good death (F=11.44, p=.001), palliative care (F=4.15, p=.045), and the meaning of life (F=5.12, p=.026) increased more significantly for participants in the experimental group than in the control group. Participants felt that they gained further knowledge in palliative patient management and refined their clinical practice. CONCLUSION: The results of the study indicate that this program could serve as a practical program for palliative care nursing in the nursing field and suggests that more attention should be directed to the diverse educational needs of nurses.
