ABSTRACT
Objective:To investigate the relationship and intrinsic mechanism between disease uncertainty, coping style, social support and caregiver burden of primary caregivers of stroke, in order to provide a theoretical basis for reducing the burden of care and improving the quality of care for stroke caregivers.Methods:In this study, the main caregivers of 314 stroke patients hospitalized in Xinjiang Uygur Autonomous Region People's Hospital from December 2021 to May 2022 were selected by convenience sampling method, and cross-sectional surveys were conducted using the general data questionnaire, the Family Scale of Disease Uncertainty, the Simple Coping Style Questionnaire, the Social Support Rating Scale, and the Caregiver Burden Scale. Model 4 in Hayes′ SPSS-Process program was used to test the mediation effect, and Model 15 was used to test the mediation effect of social support.Results:The positive predictive effect of disease uncertainty in the primary caregiver of stroke patients on the burden of caregivers was significant ( β=0.665, P<0.01). Active coping played a partial mediating role between disease uncertainty and caregiver burden, with a mediating effect of 0.306 and a mediating effect of 31.8%. The interaction between disease uncertainty and social support had a significant predictive effect on caregiver burden ( β=-0.033, P<0.05), and the interaction item between active response and social support had a significant predictive effect on caregiver burden ( β=-0.019, P<0.05). Conclusions:Positive coping is an important psychological mechanism between disease uncertainty and caregiver burden, and social support can alleviate the influence of disease uncertainty on caregiver′s burden, and can also strengthen the weakening effect of positive coping on caregiver′s burden.
ABSTRACT
Objective:To observe the level of mindfulness and coping style in patients with acute cerebral infarction (ACI) after interventional therapy, and analyze the intermediary effect of benefit finding between them, so as to provide a theorectical basis of implement mindfulness intervention in clinical practice.Methods:The 130 patients with ACI after interventional treatment in the First Affiliated Hospital of Zhengzhou University from October 2019 to October 2021 were included in this cross-sectional survey study. The general data questionnaire, Five-factor Mindfulness Scale (FFMQ), Benefit Finding Rating Scale (BFS), and Simple Coping Style Questionnaire (SCSQ) were used to analyze the relationship between benefit finding, mindfulness level and coping style, and the intermediary effect of benefit finding between them.Results:The total FFMQ score of 130 ACI patients after interventional therapy was (123.34 ± 5.14) points. The BFS score, positive coping score and negative coping score were (49.73 ± 3.41), (20.35 ± 2.25), (13.18 ± 1.45) points, respectively. The level of mindfulness and benefit were positively correlated with positive coping ( r=0.687, 0.737, both P<0.05). The level of mindfulness and benefit were negatively correlated with negative coping( r=-0.654, -0.779, both P<0.05). It was found that mindfulness level played a partial intermediatory effect on positive coping and negative coping in ACI patients after interventional therapy, with contribution rates of 49.71% and 64.58%, respectively. Conclusions:Benefit finding plays a partial intermediary effect on the level of mindfulness and coping style of patients with ACI after interventional therapy.
ABSTRACT
Objective:To explore the current status and correlation between stress overload, different cognitive emotion regulation strategies and stress response in palliative care nurses, and to provide reference for reducing stress reaction of hospice nurses.Methods:A total of 448 palliative care nurses from Beijing City, Jiangsu Province, Hunan Province and Anhui Province were selected as subjects by convenience sampling method in February 2022. The general information questionnaire, Stress Overload Scale, Cognitive Emotion Regulation Questionnaire and Stress Response Questionnaire were used to conduct a cross-sectional survey. After analyzing their scores, correlation analysis and mediating effect analysis were conducted.Results:The stress overload score of palliative care nurses was 66.00 (55.00, 67.00), and the stress response score was 80.00 (63.00, 84.00). The stress overload was positively correlated with the stress response ( r=0.735, P<0.05), and the positive emotion regulation strategy was negatively correlated with the stress response ( r=-0.440, P<0.05), negative emotion regulation strategy was positively correlated with stress response ( r=0.747, P<0.05). The cognitive emotion regulation strategy had a partial mediating effect between the stress overload and the stress response, accounting for 29.6% of the total effect. Conclusions:Cognitive emotion regulation is the mediating variable between stress overload and stress response of palliative care nurses. Managers should pay more attention to the stress level and mental health status of palliative care nurses, and guide them to choose appropriate emotional regulation strategies, so as to reduce stress response and maintain physical and mental health.
ABSTRACT
OBJECTIVES@#To investigate the physical growth and dietary characteristics of children with attention deficit hyperactivity disorder (ADHD), and to analyze their relationship with core symptoms of ADHD.@*METHODS@#A total of 268 children who were newly diagnosed with ADHD in Children's Hospital of Nanjing Medical University from June to December 2020 were included in the ADHD group, and 102 healthy children who underwent physical examination during the same period were selected as the control group. Physical evaluations and dietary surveys were conducted for both groups. ADHD diagnosis and scoring were performed according to the Diagnostic and Statistical Manual of Mental Disorders (5th edition). Factor analysis, Spearman correlation analysis, and mediation analysis were used to study the relationship between core symptoms of ADHD, dietary patterns, and physical growth.@*RESULTS@#The rate of overweight/obesity in the ADHD group was significantly higher than that in the control group (35.8% vs 21.6%, P<0.05). Three dietary patterns were extracted from the food frequency questionnaire: vegetarian dietary pattern, traditional dietary pattern, and snack/fast food pattern. The factor score for the snack/fast food pattern in the ADHD group was higher than that in the control group (P<0.05). There was a significant positive correlation between ADHD symptom scores, snack/fast food pattern factor scores, and body fat percentage (P<0.05). The mediation analysis showed that the snack/fast food pattern played a partial mediating role in the relationship between ADHD symptom scores and body fat percentage, with a mediation proportion of 26.66%.@*CONCLUSIONS@#The rate of overweight/obesity in children with ADHD is higher than that in non-ADHD children. Core symptoms of ADHD are related to dietary patterns and physical growth, with the snack/fast food pattern playing a partial mediating role in the relationship between core symptoms of ADHD and physical growth.

ABSTRACT
SUMMARY OBJECTIVE: This study aimed to investigate the sex-specific association between hyperuricemia and the risk of hypertension and whether obesity mediates this association. METHODS: This study included 31,395 (47.0% women) adults without hypertension, cardiovascular disease, or cancer at baseline who completed at least one follow-up annual examination between 2009 and 2016. Cox regression models were performed to calculate hazard ratios and 95% confidence intervals. Mediation analysis was conducted to estimate the effect of body mass index on the association between hyperuricemia and hypertension. RESULTS: During a median 2.9-year follow-up, hyperuricemia was significantly associated with a higher risk of hypertension (HR 1.15, 95%CI 1.07-1.24 for all participants; HR 1.12, 95%CI 1.03-1.22 for men; and HR 1.23, 95%CI 1.02-1.48 for women) after adjustment for potential confounders. Additional adjustment for body mass index attenuated this association (HR 1.09, 95%CI 1.08-1.10 for all participants; HR 1.07; 95%CI 0.98-1.16 for men; HR 1.18; 95%CI 0.96-1.44 for women). Mediation analysis showed that BMI partially mediated the relationship between hyperuricemia and incident hypertension (indirect effect HR 1.09, 95%CI 1.08-1.10; direct effect: HR 1.08, 95%CI 1.02-1.15). The percentage of the mediation effect was 53.2% (95%CI 37.9-84.5). CONCLUSION: Hyperuricemia is associated with a risk of hypertension in both sexes, and BMI partially mediates hyperuricemia-related incident hypertension.
ABSTRACT
Objective Although goal-directed fluid therapy (GDFT) has been proven to be effective in reducing the incidence of postoperative complications, the underlying mechanisms remain unknown. The aim of this study was to examine the mediating role of intraoperative hemodynamic lability in the association between GDFT and the incidence of postoperative complications. We further tested the role of this mediation effect using mean arterial pressure, a hemodynamic indicator. Methods This secondary analysis used the dataset of a completed nonrandomized controlled study to investigate the effect of GDFT on the incidence of postoperative complications in patients undergoing posterior spine arthrodesis. We used a simple mediation model to test whether there was a mediation effect of average real variability between the association of GDFT and postoperative complications. We conducted mediation analysis using the mediation package in R (version 3.1.2), based on 5,000 bootstrapped samples, adjusting for covariates. Results Among the 300 patients in the study, 40% (120/300) developed postoperative complications within 30 days. GDFT was associated with fewer 30-day postoperative complications after adjustment for confounders (odds ratio: 0.460, 95% CI: 0.278, 0.761; P = 0.003). The total effect of GDFT on postoperative complications was -0.18 (95% CI: -0.28, -0.07; P < 0.01). The average causal mediation effect was -0.08 (95% CI: -0.15, -0.04; P < 0.01). The average direct effect was -0.09 (95% CI: -0.20, 0.03; P = 0.17). The proportion mediated was 49.9% (95% CI: 18.3%, 140.0%). Conclusions The intraoperative blood pressure lability mediates the relationship between GDFT and the incidence of postoperative complications. Future research is needed to clarify whether actively reducing intraoperative blood pressure lability can prevent postoperative complications.

Abstract Introduction/objective: Worries regarding COVID-19 and its economic, social, and psychological consequences, together with the strict measures implemented to control this health crisis, have threatened the mental health of adolescents. The aim of this study was to test the mediating role of resilience and life satisfaction in the association between COVID-19 related worries and mental health among adolescents and young adults. Method: A total of 3485 participants between 14-29 years of age (Medad = 19.68, DT = 3.36) completed an online survey regarding pandemic-related worries, resilience, life satisfaction, and emotional symptoms (depression, anxiety, and stress). Structural Equation Modeling (SEM) was performed to test multi-group invariance. Results: Resilience and life satisfaction partly mediated the relationship between pandemic-related worries and emotional symptoms. Pandemic-related worries were positively associated with emotional symptoms. Resilience and life satisfaction mediated the impact of pandemic-related worries on emotional symptoms. The tested model was invariant according to gender and age. Conclusions: Our findings go beyond the context of the current pandemic, highlighting how young people's worries regarding extraordinary circumstances may negatively impact on their mental health. This study highlights the mediating role of life satisfaction and resilience, thus emphasising the need for promoting these aspects to improve the mental health of young people during this global health crisis.

ABSTRACT
Objective:To explore the relevance of family resilience, fatalism, and self-management of lung neoplasms patients undergoing chemotherapy, and the mediating effect of fatalism in family resilience and self-management.Methods:The study was a cross-sectional study, and it was convenient to select 376 lung cancer patients who underwent chemotherapy in the Oncology Department of the Second Affiliated Hospital of Air Force Military Medical University from August 2020 to August 2021 as the research subjects. A questionnaire survey was conducted on the patients by using general information questionnaire, Chinese Family Resilience Assessment Scale, Chinese Version of Fatalism Scale, and Cancer Patient Self-management Assessment Scale to establish and test the mediating model of fatalism between family resilience and self-management in lung neoplasms patients undergoing chemotherapy.Results:The total score of family resilience of lung neoplasms patients undergoing chemotherapy was (102.01 ± 33.29) points, the total score of fatalism was (63.99 ± 9.41) points, and the total score of self-management was (87.95 ± 27.65) points. Family resilience was negatively correlated with fatalism ( r=-0.418, P<0.01), positively correlated with self-management ( r=0.476, P<0.01), and fatalism was negatively correlated with self-management ( r=-0.557, P<0.01). Fatalism played a partial mediating role between family resilience and self-management, and the mediating effect accounted for 26.2% of the total effect. The value of each fitness index of the mediation effect model was within the acceptable range Conclusions:Family resilience, fatalism and self-management of lung neoplasms patients undergoing chemotherapy are closely related. Family resilience can not only directly affect self-management, but also indirectly affect self-management through fatalism. In clinical nursing, targeted intervention can be carried out on fatalism, which affects the role of family resilience on self-management, thereby promoting the improvement of self-management level of lung neoplasms patients undergoing chemotherapy.
ABSTRACT
Objective:To investigate whether rumination and family functioning can predict the level of depression after 1 year of follow-up in patients with first-episode depression, and whether family functioning plays a mediating role between rumination and depression level.Methods:Sixty-five patients with first-episode depression who met the enrollment requirements were included, and all subjects were assessed the 17-item Hamilton depression scale(HAMD-17), rumination response scale(RRS) and family assessment device(FAD). All subjects were followed up for 1 year, and the predictive effects of rumination and family functioning at baseline on the level of depression after 1 year of follow-up were investigated by hierarchical linear regression analysis and mediation analysis.Results:At the baseline stage, rumination, role, affective involvement (AI) and general functioning (GF) were significantly positively associated with depression level after 1 year of follow-up in patients with first-episode depression ( r=0.49, P<0.01; r=0.30, P=0.02; r=0.43, P<0.01; r=0.50, P<0.01; respectively). Rumination, AI and GF at the baseline stage predicted depression level after 1 year of follow-up ( β=0.315, t=2.954, P=0.005; β=0.261, t=2.550, P=0.013; β=0.323, t=2.952, P=0.005). Mediation analysis showed that AI and GF partially mediated the relationship between rumination at baseline and depression level at 1 year follow-up (point estimate value for AI=0.040, 95% CI=0.012-0.090); point estimate value for GF=0.066, 95% CI=0.017-0.143). Conclusions:Rumination and family functioning at baseline in first-episode depressed patients can predict the depression level at 1 year follow-up.Family functioning partly mediates the relationship between the baseline rumination and the depression level at 1 year follow-up.
ABSTRACT
Objective:To explore the mediating effect of caring ability of family caregivers on dementia patients′ self-care ability and family caregiver burden.Methods:A total of 113 dementia caregivers of dementia patients recruited in Shandong Provincial Hospital Affiliated to Shandong First Medical University and Shandong Mental Health Center from September 2020 to January 2021 were selected, and the Barthel Index, Family Caregiver Task Inventory and Zarit Burden Interview were used to capture their responses on dementia patients′ self-care ability, caring ability, and caregiver burden.Results:The score of self-care ability of dementia patients was (75.19 ± 28.56), and scores of caring ability and care burden of caregivers were 9.00(4.00, 15.00) and (33.78 ± 16.53), respectively. The self-care ability of dementia patients was negatively associated with caring ability and care burden of caregivers ( r=-0.424, -0.420, both P<0.01), and the caring ability and care burden were positively correlated ( r=0.605, P<0.01). The intermediary effect of dementia caregivers' caring ability between patients' self-care ability and caregivers' care burden is significant. The indirect effect was -0.107 and the total effect was -0.187. The indirect effect accounted for 57.22% of the total effect. Conclusions:Caring ability of family caregivers mediates the relationship between self-care ability of dementia patients and caregivers' care burden.The caring ability may be used as an intervening target for future studies.
ABSTRACT
It is unclear whether physical activity and cardiorespiratory fitness (CRF) are pathways that link low pulmonary function (LPF) to increased blood pressure (BP). Therefore, we investigated the extent to which CRF and moderate-to-vigorous physical activity (MVPA) mediate the relationship between LPF and high BP in adults. We conducted a cross-sectional study with 1,362 participants that underwent cardiopulmonary exercise testing (CPET), spirometry, and wore an accelerometer to determine physical activity patterns. We performed mediation analyses using structural equations considering peak oxygen uptake (V̇O2) and MVPA as mediators, forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) as independent variables, and systolic and diastolic blood pressure (SBP, DBP) as dependent variables. The probability of alpha error was set at 5%. We found a significant total effect of FVC on SBP and DBP considering V̇O2 as mediator (P<0.01). Indirect effects were also significant, with 42.6% of the total effect of FVC on SBP and 77% on DBP mediated by V̇O2 (P<0.01). We did not observe a direct effect of FVC on SBP and DBP. Considering FEV1 as an independent variable, the total effect on SBP was also significant, as were the indirect effects, mediated by V̇O2 at 14.8% for SBP and 7.6% for DBP (P<0.01). We did not find an indirect effect of FVC or FEV1 considering the MVPA as a mediator. CRF mediates the pathway that links LPF and elevated BP. Therefore, CRF is more sensitive to variations in FVC and FEV1 than MVPA.

Objective:To understand the status quo of male nurses′ resilience, social support and simple coping styles in Heilongjiang Province, and to analysis the mediating effect of resilience between social support and simple coping styles.Methods:The questionnaire star was used to survey 780 nurses from 13 departments including such as intensive care unit, emergency department, psychiatric department, and operating room etc in Harbin 9 hospitals from November to December 2018 by convenience sampling. The self-made general information questionnaire, Connor-Davidson Resilience Scale (CD-RISC), Social Support Rating Scale (SSRS) and Simplified Coping Style Questionnaire (SCSQ) were used to assess the resilience, social support and simple coping style.Results:The average score of resilience of male nurses in Heilongjiang Province was (72.36±16.69) points, the average score of social support was (37.21±8.70) points, the average items score of positive coping style was (2.18±0.52) points, negative coping style items score was (1.53±0.76) points. Social support and positive coping styles all showed a significant positive correlation with resilience ( r values were 0.432, 0.747, P<0.01). The results of mediation analysis showed that resilience played a part of mediation between social support and active coping styles. The mediation effect was 21.05%, accounting for 63.21% of the total effect. Conclusion:In order to effectively maintain the mental health of male nurses in Heilongjiang Province and improve their active coping level, it is necessary to ensure that the nurses have a good level of resilience.
ABSTRACT
Objective:To investigate the relationships of expectation gap of postpartum support with perceived stress and postpartum depression, and the mediating role of the former in the association between the latter two.Methods:A total of 278 convenient sample of puerperas at 6-8 weeks after delivery from June to August in 2019 in Shenzhen Hospital of Southern Medical University were investigated with the Perceived Stress Scale, the Chinese version of the Postpartum Social Support Questionnaire, and the Edinburgh Postnatal Depression Scale. Structure equation model was established and Bootstrap method was used to explore the direct and indirect effects of these variables.Results:The perceived stress score, and expectation gap of postpartum support score were (26.50±2.50), (25.30±5.79), respectively; and the postpartum depression score was (14.60±2.10). The incidence of postpartum depression(defined as postpartum depression score ≥10) was 37.4%(104/278). Path analysis showed that the model was well fitted (χ 2/ df was 0.265, Tucker-Lewis index was 1.0, comparative fit index was 1.0,root mean square of approximate error was 0, root mean square of standard deviation and residual error was 0.04). Perceived stress positively correlated with expectation gap of postpartum support, and postpartum depression ( P<0.05). Expectation gap of postpartum support positively correlated with postpartum depression ( P<0.05). The effect of perceived stress on postpartum depression was partially mediated by expectation gap of postpartum support (Estimate was 0.285, 95% CI 0.197-0.352). Conclusions:Perceived stress had direct or indirect effect via expectation gap of postpartum support on postpartum depression. This indicated that the medical staff can build a comprehensive support system, reduce the experience of perceived stress among puerperas, improve social support satisfaction, and thus reduce the incidence of postpartum depression.
ABSTRACT
Objective@#To explore the mediation mechanism of coronary artery lesion among both male and female Kawasaki disease (KD) children.@*Methods@#Children with KD that hospitalized in the Wenzhou Medical University affiliated Yuying Children’s Hospital from January 2009 to December 2014, were included in this study. Differences on demographical characteristics, clinical manifestations, laboratory indicators, regimen and time of treatment, results from pre/post echocardiography and treatment between male and female patients, were compared. The independent effect of gender on the risk of coronary artery lesions (CAL) was evaluated, and the mediating effect of BMI, visiting time and KD type on the association between gender and CAL were also studied.@*Results@#The average BMI level of male patients was higher than that of female patients. The difference was statistically significant (P<0.001). The prevalence of overweight among male patients (20.9%) was higher than female (14.1%). The difference was statistically significant (P=0.011). Data from the multivariate logistic regression analysis confirmed that the incidence of CAL in male patients was higher than that in female patients (aOR=1.50, 95%CI: 1.06-2.12) but the CAL was mainly different before on the immunoglobulin therapy. Results from the mediation analysis showed that BMI was an important mediator in the association between gender and CAL, with the indirect effect as 1.05 (95%CI: 1.01- 1.10) and the proportion mediated as 13.0%.@*Conclusions@#Male patients presented higher incidence of CAL but was mainly reflected in the difference of CAL before the treatment. BMI was probably an important mediator related to the association between gender and CAL.
ABSTRACT
Mediation analysis is mainly used to explore the causal mechanism between independent variable X and dependent variable Y. It determines whether mediator M plays a role and evaluate the role’s degree in the causal path by decomposing the causal path between the independent variable X and the dependent variable Y. However, the classical mediation analysis is generally used for single mediator. This paper introduces a new mediation analysis method for multiple mediators.
ABSTRACT
Background: Perceived stress and burnout are by-products of powerless responsibility imposed on resident doctors. Emotional intelligence (EI) works as an adapting and coping tool. Objective: The objective of this study is to find out the role of work-related perceived stress on burnout and influence of EI on it. Methods: A descriptive cross-sectional study was conducted from February to April 2016 among 63 resident doctors of different departments of Bankura Sammilani Medical College and Hospital. Data were collected through a self-administered questionnaire for background characteristics and work-related variables. Cohen perceived stress scale, Trait EI, and Shirom-Melamed burnout questionnaire were applied for measuring perceived stress, EI, and burnout, respectively. Statistical analysis was done with of SPSS version 22.0, and for mediation analysis, Andrew F. Hyne抯 SPSS macro was adopted. Nonparametric bootstrapping was done assuming small sample. Results: Out of complete responses, 67%, 22.9%, and 9.8% were from clinical, paraclinical, and preclinical specialties, respectively. Burnout had a significant positive correlation with perceived stress and in negative correlation with EI-well-being and positive correlation with EI-self-control and sociability. Physical fatigue factor of burnout had a significant positive correlation with EI-emotionality. Perceived stress had a negative correlation with EI-well-being. On mediation analysis, assuming EI as a mediator, total, direct, and indirect effects of perceived stress on burnout were significant (<0.05). Mediation was proved to act with percent mediation of 0.07. Conclusion: There was definite mitigating effect of EI on burnout by perceived stress among resident doctors. This necessitates more attention by decision-makers toward this burning problem for the sake of care of caregivers.
