The traditional Chinese medicine Qiliqiangxin in heart failure with reduced ejection fraction: a randomized, double-blind, placebo-controlled trial.

Previous findings have indicated the potential benefits of the Chinese traditional medicine Qiliqiangxin (QLQX) in heart failure. Here we performed a double-blind, randomized controlled trial to evaluate the efficacy and safety of QLQX in patients with heart failure and reduced ejection fraction (HFrEF). This multicenter trial, conducted in 133 hospitals in China, enrolled 3,110 patients with HFrEF with NT-proBNP levels of ≥450 pg ml-1 and left ventricular ejection fraction of ≤40%. Participants were randomized to receive either QLQX capsules or placebo (four capsules three times daily) alongside standard heart failure therapy. The trial met its primary outcome, which was a composite of hospitalization for heart failure and cardiovascular death: over a median follow-up of 18.3 months, the primary outcome occurred in 389 patients (25.02%) in the QLQX group and 467 patients (30.03%) in the placebo group (hazard ratio (HR), 0.78; 95% confidence interval (CI), 0.68-0.90; P < 0.001). In an analysis of secondary outcomes, the QLQX group showed reductions in both hospitalization for heart failure (15.63% versus 19.16%; HR, 0.76; 95% CI, 0.64-0.90; P = 0.002) and cardiovascular death (13.31% versus 15.95%; HR, 0.83; 95% CI, 0.68-0.996; P = 0.045) compared to the placebo group. All-cause mortality did not differ significantly between the two groups (HR, 0.84; 95% CI, 0.70-1.01; P = 0.058) and adverse events were also comparable between the groups. The results of this trial indicate that QLQX may improve clinical outcomes in patients with HFrEF when added to conventional therapy. ChiCTR registration: ChiCTR1900021929 .

A multimodal cancer rehabilitation programme promoting sense of coherence for women treated for female reproductive cancers: a pilot randomised controlled trial.

PURPOSE: To investigate the feasibility, acceptability, and preliminary effects of a theory-driven multimodal cancer rehabilitation intervention (MCRI) programme among Hong Kong Chinese women treated for female reproductive cancers (FRC). METHODS: A single-blinded randomised controlled trial was conducted in two regional hospitals in Hong Kong involving 35 women treated for FRC. The intervention group (n = 18) received a 12-week MCRI which included 30 modules of app-based health education and three nurse-led individual counselling sessions. The control group (n = 17) received attention from the research nurse through telephone calls. Sense of coherence, health-related quality of life, and cancer-specific distress were measured at baseline (T0), immediately after completion of the intervention (T1) and 12 weeks post-intervention (T2). Twelve intervention completers were interviewed to explore the acceptability of the programme. RESULTS: Recruitment, consent, and retention rates, counselling session attendance rate, and app usage were satisfactory. The intervention participants reported to have significant improvement in physical well-being at T1 (Cohen's d effect size (d) = 1.04, 95% CI 0.24, 1.83), sense of coherence (d = 0.76, 95% CI - 0.03, 1.54), and cancer-specific distress (d = 1.03, 95% CI - 1.83, - 0.21) at T2. Interviewed participants acknowledged the benefits of the programme and provided comments for improvement. CONCLUSIONS: The MCRI is found to be feasible and acceptable and may improve their sense of coherence, distress, and physical health. A full-scale trial using a larger and more representative sample is warranted to confirm the effects of the programme. IMPLICATIONS FOR CANCER SURVIVORS: Women treated for FRC may be benefited from the MCRI in improving sense of coherence, physical well-being, and distress. TRIAL REGISTRATION: This trial was registered on ISRCTN registry with ID ISRCTN73177277.

The risk of stroke and post-stroke mortality in people with schizophrenia: A systematic review and meta-analysis study.

Sources of heterogeneity in risk of stroke and mortality risk following acute-stroke in schizophrenia are understudied. We systematically searched four electronic-databases until 1-November-2022, and conducted meta-analysis to synthesize estimates of stroke-risk and post-stroke mortality for schizophrenia patients relative to non-schizophrenia counterparts. Subgroup-analyses and meta-regression models stratified by sex, nature of sample (incident/prevalent), geographical region, study-period and time-frame following stroke were conducted when applicable. Fifteen and 5 studies were included for meta-analysis of stroke-risk (n=18,368,253; 129,095 schizophrenia patients) and all-cause post-stroke mortality (n=289,231; 4,477 schizophrenia patients), respectively. Schizophrenia patients exhibited elevated stroke-risk (relative-risk =1.55[95% CI:1.31-1.84]) relative to non-schizophrenia controls. Schizophrenia was associated with increased stroke-risk in both sexes, study-periods of 1990s and 2000s, and irrespective of nature of sample and geographical regions. Meta-regression revealed regional differences in relative-risk for stroke, but limited by small number of studies. After removal of an outlier study, meta-analysis demonstrated that schizophrenia was associated with increased overall (hazard-ratio=1.37[1.30-1.44]), short-term (≤90 days; 1.29[1.14-1.46]) and longer-term (≥1 year; 1.45[1.32-1.60]) post-stroke mortality rates. Raised post-stroke mortality rate for schizophrenia was observed irrespective of nature of sample, geographical regions and study-periods. Taken together, schizophrenia is associated with increased stroke-risk and post-stroke mortality. Multilevel-interventions are required to reduce these physical-health disparities.

Use of Anticoagulation for Thromboembolic Prophylaxis in Patients With Atrial High-Rate Episodes on Device Monitoring: A Narrative Review.

Ischemic stroke and systemic thromboembolism are primary drivers of significant morbidity and mortality in patients with atrial fibrillation (AF). Although stroke is commonly the first index presentation of clinically silent AF, the growing use of continuous rhythm monitoring through cardiac implanted electronic devices has enabled earlier and increased detection of AF in patients who are otherwise asymptomatic before stroke development. Atrial high-rate episodes (AHREs) are atrial tachyarrhythmias frequently detected by cardiac implanted electronic devices; these events represent subclinical AF and other atrial tachyarrhythmias that can lead to stroke development and AF. Although the presence of AHREs increases the risk of developing both clinical AF and stroke compared with absence of AHREs, there has been a significant clinical variability in anticoagulation initiation in these subjects. In this narrative review, we explore the current evidence and published research surrounding the association between AHREs and stroke development in addition to the utility of anticoagulation in this population for thromboembolic prophylaxis.

Diblock bottlebrush polymer in a non-polar medium: Self-assembly, surface forces, and superlubricity.

Whilst bottlebrush polymers have been studied in aqueous media for their conjectured role in biolubrication, surface forces and friction mediated by bottlebrush polymers in non-polar media have not been previously reported. Here, small-angle neutron scattering (SANS) showed that a diblock bottlebrush copolymer (oligoethyleneglycol acrylate/ethylhexyl acrylate; OEGA/EHA) formed spherical core-shell aggregates in n-dodecane (a model oil) in the polymer concentration range 0.1-2.0 wt%, with a radius of gyration Rg âˆ¼ 7 nm, comprising 40-65 polymer molecules per aggregate. The surface force apparatus (SFA) measurements revealed purely repulsive forces between surfaces bearing inhomogeneous polymer layers of thickness L âˆ¼ 13-23 nm, attributed to adsorption of a mixture of polymer chains and surface-deformed micelles. Despite the surface inhomogeneity, the polymer layers could mediate effective lubrication, demonstrating superlubricity with the friction coefficient as low as µ ∼ 0.003. The analysis of velocity-dependence of friction using the Eyring model shed light on the mechanism of the frictional process. That is, the friction mediation was consistent with the presence of nanoscopic surface aggregates, with possible contributions from a gel-like network formed by the polymer chains on the surface. These unprecedented results, correlating self-assembled polymer micelle structure with the surface forces and friction the polymer layers mediate, highlight the potential of polymers with the diblock bottlebrush architecture widespread in biological living systems, in tailoring desired surface interactions in non-polar media.

Validation of evidence-based questionnaire for TCM syndrome differentiation of heart failure and evaluation of expert consensus.

BACKGROUND: Traditional Chinese Medicine (TCM) is widely used to treat heart failure (HF). Syndrome differentiation is a unique and crucial component in TCM practice for guiding disease diagnosis and treatment strategies as well as clinical research. The major bottlenecks in TCM syndrome differentiation are the diversity of the syndrome differentiation criteria and the broad spectrum of syndrome patterns, hindering evidence-based studies for clinical research. In the present study, we aim to develop an evidence-based questionnaire for the diagnosis of HF and establish a definitive set of criteria for syndrome differentiation. METHODS: We designed a TCM syndrome differentiation questionnaire for heart failure (SDQHF) based on the "TCM expert consensus for diagnosis and treatment of heart failure" (expert consensus), literature review, and various clinical guidelines. To test the reliability and efficiency of the questionnaire, we performed a large-scale multiple-center clinical trial with the recruitment of 661 HF patients. Cronbach's alpha was used to assess the internal consistency of the SDQHF. Content validity was conducted through expert review. Principal component analysis (PCA) was applied to evaluate the construct validity. We constructed a proposed model for syndrome differentiation for HF based on the PCA results. Tongue analysis was performed to verify the accuracy of syndromes derived from the proposed model and the expert consensus. An evidence-based practical questionnaire for TCM syndrome differentiation patients was developed and validated with the data from 661 HF patients. RESULTS: The syndrome differentiation criteria were constructed with five syndrome elements (qi-deficiency, yang-deficiency, yin-deficiency, blood stasis, and phlegm retention). The results revealed good convergent and discriminant validity, satisfactory internal consistency, and feasibility. The significant discoveries include: (1) A total of 91% of the derived TCM syndromes from the proposed model matched with the characterized tongue images of the syndrome patterns; (2) Qi Deficiency Syndrome is the dominant syndrome pattern for HF patients, followed by Yang-Qi Deficiency Syndrome and Qi-yin deficiency Syndrome, and finally, Yin-Yang Dual Deficiency Syndrome; (3) The majority of the HF patients had the combination of Blood Stasis and Phlegm Retention Syndromes; (4) The "Yin-Yang Dual Deficiency" Syndrome was a valid syndrome for HF, suggesting that this syndrome pattern should be included in the criteria for syndrome differentiation; and (5) Through the validation of the expert consensus, several recommendations were proposed to improve the accuracy of syndrome differentiation of HF. CONCLUSIONS: The proposed SDQHF and the criteria could be a reliable and valid tool for syndrome differentiation of heart failure with high accuracy. It is recommended to use the proposed model for evidence-based study on Chinese Medicine to diagnose and treat HF. TRIAL REGISTRATION NUMBER: The trial was registered at the Chinese Clinical Trial Registry, http://www.chictr.org.cn . (Registration No.: ChiCTR1900021929); Date: 2019-03-16.

Feasibility and acceptability of a culturally-adapted Women's Wellness After Cancer Programme for Chinese women treated for gynaecological cancer: A pilot randomised controlled trial.

Objective: To assess the feasibility and acceptability of a culturally-adapted Women's Wellness After Cancer Programme (WWACPHK) for improving health-related quality of life, anxiety and depressive symptoms and enhancing self-efficacy in engaging in healthy lifestyles among Chinese women treated for gynaecological cancer. Methods: This pilot randomised controlled trial was conducted from May to December 2018. Twenty-six women aged 18 or above who had completed treatment for gynaecological cancer were recruited from a gynaecology outpatient clinic of a public hospital in Hong Kong. They were randomised into intervention (n = 15) or control (n = 11) groups. All data collectors were blinded to the group allocation. Intervention participants were given access to the WWACPHK website and an online discussion forum facilitated by a trained research nurse for 12 weeks, while control participants received standard care. Trial feasibility was assessed by recruitment, consent, and retention rates and website use. Acceptability was explored through semi-structured interviews. Additionally, we trialed the data collection procedure and collected preliminary data on health-related quality of life, anxiety and depressive symptoms, dietary and exercise self-efficacy. Results: Of the 26 participants (Median age = 53.5 years) randomised, three participants dropped out of the study. Recruitment, consent and retention of participants and website use were satisfactory. No posting was made on the discussion forum. The intervention participants (n = 13) exhibited significantly greater improvement than the controls (n = 10) in perceived self-efficacy in adhering to an exercise routine at post-intervention (Cohen's d effect size(d) = 1.06, 95% confidence interval (CI): 0.18, 1.92) and 12-weeks after completion (d = 1.24, 95% CI: 0.32, 2.13). All participants were satisfied with the intervention. Conclusions: The WWACPHK is feasible and acceptable to Chinese women treated for gynaecological cancer and may improve their exercise self-efficacy. A larger-scale study is required to confirm its effects. Trial registrationhttps://www.isrctn.com identifier: ISRCTN12149499.

Is high-fidelity simulation-based training in emergency nursing effective in enhancing clinical decision-making skills? A mixed methods study.

AIM: To evaluate the effects of a high-fidelity simulation-based training in emergency nursing and the relationships between study outcomes. The objectives were to: (1) evaluate the effects of high-fidelity simulation-based training in emergency nursing on final-year nursing students' generic capabilities, self-confidence and anxiety during clinical decision-making; (2) examine the relationships between the outcomes of generic capabilities and clinical decision-making skills; (3) examine participants' satisfaction with the simulation experience; and (4) explore their experiences and opinions of the training module. BACKGROUND: Following the emergence of coronavirus disease 2019, safety and other considerations have limited the clinical training opportunities available to nursing students. This has resulted in the increased use of high-fidelity simulations to provide clinical training for nursing students. However, evidence of the effects of such training modalities on generic capabilities, clinical decision-making skills and learning satisfaction remains lacking. In particular, the effectiveness of high-fidelity simulations of emergency clinical situations in training has not been closely evaluated. DESIGN: A mixed methods study incorporating quasi-experimental and qualitative components. METHODS: We recruited a convenience sample of 255 final-year pre-registration nursing students (183 bachelor and 72 master students) from a government-funded local university in Hong Kong. Four case scenarios of emergency nursing were developed and simulated in the simulation wards of the study institution in May and June 2021. We assessed the pre- and post-intervention outcomes of generic capabilities and clinical decision-making skills. We also explored the participants' post-intervention satisfaction, experiences and opinions. RESULTS: Post-intervention, the participants reported significant improvements in generic capabilities, self-confidence and anxiety during clinical decision-making. They expressed a high level of satisfaction with the simulation experience. Additionally, we detected significant relationships between generic capabilities and clinical decision-making skills. Qualitative data analysis yielded four themes that either confirmed or complemented the quantitative findings. CONCLUSIONS: This study provides evidence of the effectiveness of high-fidelity simulation-based training in emergency nursing in enhancing students' learning outcomes. Further studies should include a control group, evaluate students' knowledge and skills, and retention of knowledge to confirm the true impact of such training.

Genetic/genomic literacy, attitudes and receptivity of nursing students and practising nurses: A cross-sectional online survey.

BACKGROUND: The growing demand for personalised nursing care in the genomic era requires nursing students and practising nurses to be better prepared to apply the knowledge of genetics/genomics to nursing practice. Several studies have shown that, despite having positive attitudes/receptivity towards integrating genetics/genomics into nursing practice, nursing students and professionals report a low level of genetic/genomic literacy. However, little is known about the status in Hong Kong. OBJECTIVES: We assessed and compared the genetic/genomic literacy and attitudes/receptivity towards integrating genetics/genomics into nursing practice among nursing students and practising nurses in Hong Kong. We also explored the relationships between the students' background characteristics, attitudes/receptivity towards integrating genetics/genomics into nursing practice and genetic/genomic literacy. DESIGN: A cross-sectional online survey conducted between March 2020 and January 2022. SETTINGS: A government-funded university in Hong Kong. PARTICIPANTS: We recruited a convenience sample of 234 nursing students, 145 were final-year undergraduate students (median age = 22 years, 84.1 % female) and 89 were practising registered nurses (postgraduate students studying part-time programme, median age = 28 years, 77.5 % female). METHODS: The survey collected the participants' background information, attitudes/receptivity towards integrating genetics/genomics into nursing practice and levels of genetic/genomic literacy. RESULTS: Overall, the participants reported positive attitudes/receptivity towards practice integration but had low levels of genetic/genomic literacy. Practising nurses were more likely to have lower genetic/genomic literacy, but more positive attitudes/receptivity towards practice integration, than undergraduate students. Multiple regression analysis suggested that the level of study (postgraduate/undergraduate programme) and perceptions of the disadvantages of 'needing to re-tool professionally' were significant independent factors associated with the level of genetic/genomic literacy. CONCLUSIONS: Findings from this study call for the strategic integration of genetics/genomics education into all levels of nursing education in Hong Kong and across the globe. In particular, sustained efforts should be made to ensure that practising nurses receive further education in genetics/genomics.

Management of Severe Coarctation of the Aorta and Bilateral Carotid Artery Stenosis: An Interventional Catch-22.

We present a case of an adult with concurrent severe aortic coarctation, bilateral carotid artery stenosis, and anomalous right subclavian artery, posing the interventional dilemma of accepting potential cerebral hyperperfusion syndrome vs hypoperfusion ischemic injury. Transcatheter stenting of the aortic coarctation was successfully performed without any neurological deficits. (Level of Difficulty: Beginner.).

Wide-Bandwidth Nanocomposite-Sensor Integrated Smart Mask for Tracking Multiphase Respiratory Activities.

Wearing masks has been a recommended protective measure due to the risks of coronavirus disease 2019 (COVID-19) even in its coming endemic phase. Therefore, deploying a "smart mask" to monitor human physiological signals is highly beneficial for personal and public health. This work presents a smart mask integrating an ultrathin nanocomposite sponge structure-based soundwave sensor (≈400 µm), which allows the high sensitivity in a wide-bandwidth dynamic pressure range, i.e., capable of detecting various respiratory sounds of breathing, speaking, and coughing. Thirty-one subjects test the smart mask in recording their respiratory activities. Machine/deep learning methods, i.e., support vector machine and convolutional neural networks, are used to recognize these activities, which show average macro-recalls of ≈95% in both individual and generalized models. With rich high-frequency (≈4000 Hz) information recorded, the two-/tri-phase coughs can be mapped while speaking words can be identified, demonstrating that the smart mask can be applicable as a daily wearable Internet of Things (IoT) device for respiratory disease identification, voice interaction tool, etc. in the future. This work bridges the technological gap between ultra-lightweight but high-frequency response sensor material fabrication, signal transduction and processing, and machining/deep learning to demonstrate a wearable device for potential applications in continual health monitoring in daily life.

Factors influencing COVID-19 vaccination uptake among community members in Hong Kong: a cross-sectional online survey.

OBJECTIVE: Vaccination is recognised as the most effective approach to contain the spread of the COVID-19 pandemic in the long run. However, the global vaccination uptake is still suboptimal. Although a considerable number of studies have focused on factors influencing intention or acceptance of COVID-19 vaccination, few explore the factors that affect actual vaccination uptake. This study aimed to explore the factors influencing COVID-19 vaccination uptake among the general public in a developed country. DESIGN: A cross-sectional online survey was conducted between June and August 2021. SETTING AND PARTICIPANTS: Community members in Hong Kong were recruited through convenient and snowball sampling to complete an anonymous online survey. OUTCOME MEASURES: The outcomes of this study included participants' sociodemographic characteristics, vaccination status and perceived impact of COVID-19, and their attitudes towards COVID-19. RESULTS: A total of 358 valid questionnaires were received. The results showed that 50.8% of the participants received two doses of the vaccine. Multivariable logistic regression analysis suggested that the participants' vaccination uptake was associated with their jobs affected by COVID-19, had an income source, perceived good/excellent physical health status, perceived COVID-19 exposure, perceived good/excellent knowledge of COVID-19, learnt about the vaccine from printed materials and perceived that their family members were at risk of contracting COVID-19. CONCLUSIONS: This is one of the first few cross-sectional studies that explored factors associated with the actual vaccination uptake of the general public during the COVID-19 pandemic. The results can provide insights for formulating strategies to increase COVID-19 vaccination rates in developed countries.

Psychological Wellbeing and Associated Factors Among Ethnic Minorities During the COVID-19 Pandemic.

This study assessed the psychological wellbeing and its associated factors amongst ethnic minorities during the coronavirus disease 2019 (COVID-19) pandemic. A total of 310 Hong Kong South Asians aged 41.3 (SD 13.7) years completed an anonymous online survey between July 2020 and February 2021. The results showed an overall moderate level of stress and high levels of depression, anxiety and post-traumatic stress disorder (PTSD) symptoms amongst South Asian minorities. Multivariable regression analyses suggested that being single/divorced, following Hinduism or other non-Muslim religions, having lower perceived knowledge of COVID-19 and having worried about losing job were significant predictors of higher levels of depression, anxiety and/or stress; additionally, being male, having a low monthly household income, having worried about losing job and healthcare collapse were significant predictors of a higher level of PTSD symptoms. The findings suggest an urgent need to alleviate the psychological impacts of the COVID-19 pandemic on ethnic minorities, specifically for those most vulnerable to these impacts.

Psycho-behavioural responses of the general population to COVID-19 after mass vaccination: a cross-sectional study.

Background: Previous studies have examined public psycho-behavioural responses in the early stages of the epidemic, little is known after mass vaccination has been implemented. This study aimed to investigate the public's behavioural (adoption of COVID-19 precautionary measures) and psychological (depression, anxiety and stress) responses to COVID-19 and their relationships after the launch of the territory-wide vaccination programme in Hong Kong. Methods: A cross-sectional survey study using anonymous online or face-to-face questionnaires was conducted between June 2021 and September 2021. A convenience sample of Hong Kong Chinese residents aged ⩾18 years were recruited online by referrals and from a university-run community vaccination centre. Results: A total of 1893 valid questionnaires were received. The results showed that Hong Kong residents have high levels of adoption of precautionary measures and low levels of depression, anxiety and stress after the mass vaccination. Hierarchical regression analysis identified that in the fully adjusted model, the adoption of precautionary measures was a consistent protective factor (ß ranged -1.51 to -1.67, p < 0.001) for depression, anxiety and stress amid the COVID-19 pandemic. Conclusions: This study offers new information on the public's psycho-behavioural responses to the pandemic, as well as insights into public health planning after introducing the mass vaccination.

Study protocol: Traditional Chinese Medicine (TCM) syndrome differentiation for heart failure patients and its implication for long-term therapeutic outcomes of the Qiliqiangxin capsules.

BACKGROUND: Syndrome differentiation is a commonly used methodology and practice in Traditional Chinese Medicine (TCM) guiding the diagnosis and treatment of diseases including heart failure (HF). However, previous clinical trials seldom consider the impact of syndrome patterns on the outcome evaluation of TCM formulae. Qiliqiangxin (QLQX) capsule is a TCM formula with cardiotonic effect to improve the cardiovascular function for heart failure with proven efficacy from well-designed clinical trials. Though, there is no clinical trial with a large sample size and long assessment period that considers the relationship between TCM syndrome differentiation and the treatment efficacy of QLQX. In the present study, we design a study protocol to evaluate the relationship between TCM syndrome differentiation and the severity of heart failure as well as its progression. Furthermore, we will evaluate the impact of the TCM syndrome patterns on the efficacy of QLQX in the outcome of heart failure. METHODS: This is a clinical study conducted in conjunction with an ongoing clinical trial (QUEST Study) by sharing the parent patient populations but with different aims and independent designed roadmaps to investigate the TCM syndrome pattern distributions and the impacts of syndrome pattern types on the efficacy of QLQX in HF treatment. The clinical trial involves over 100 hospitals in mainland China and Hong Kong SAR with 3080 HF patients. By assessing the morbidity and re-hospitalization, we will verify and apply a modified TCM Questionnaire to collect the clinical manifestations of HF and acquire the tongue images of the patients to facilitate the syndrome differentiation. We will base on the "2014 Consensus from TCM experts on diagnosis and treatment of chronic heart failure" to evaluate the TCM syndromes for the patients. A pilot study with at least 600 patients will be conducted to evaluate the reliability, feasibility and validity of the modified TCM questionnaire for syndrome differentiation of HF and the sample size is calculated based on the confidence level of 95%, population size of 3080 and 5% margin of error. Secondly, we will investigate the characteristic of TCM syndrome distribution of HF patients and its correlation with the functional and biochemical data. Furthermore, we will evaluate the relationship between the TCM syndrome patterns and the efficacy of QLQX in the treatment of heart failure. Lastly, we will investigate the implication of tongue diagnosis in the severity and therapeutic outcome of HF. EXPECT OUTCOMES: To our knowledge, this is the first large scale clinical trial to evaluate the impacts of TCM syndrome differentiation on the progression and therapeutic outcome of HF patients and explore the diagnostic value of TCM Tongue Diagnosis in HF patients. We expect to obtain direct clinical evidence to verify the importance of TCM syndrome differentiation for the diagnosis and treatment of HF. TRIAL REGISTRATION: The trial was registered at Chinese Clinical Trial Registry, http://www.chictr.org.cn . (Registration No.: ChiCTR1900021929); Date: 2019-03-16.

Physical Activity and Sedentary Behaviors among Chinese Children: Recent Trends and Correlates.

OBJECTIVE: This study was aimed at examining the trends and correlates of physical activity (PA) and sedentary behaviors among Chinese children. METHODS: A total of 4,341 subjects (6,936 observations) aged 6-17 years who participated in the China Health and Nutrition Survey (2004-2015) were included. Of the subjects, 41% participated in the survey twice or more. Random-effects ordinal regression models and repeated-measures mixed-effects models were used to examine the PA trends. Quantile regression models were applied to examine the factors influencing PA and sedentary behaviors. RESULTS: From 2004 to 2015, the prevalence of physical inactivity among Chinese children aged 6-17 years increased by 5.5% [odds ratio ( OR), 1.51; 95% confidence interval ( CI), 1.19-1.90; P < 0.001]. The PA volume declined by 5.8 metabolic equivalent of task-hr/week ( P < 0.001), and the time spent in sedentary behaviors increased by 1.8 hr/week ( P < 0.001). Age, ethnicity, and region showed significant effects on the PA volume across the quartiles ( P < 0.001). Across the quartiles, sedentary time was significantly higher in the children residing in urban areas ( P < 0.001) or areas with high urbanization levels ( P ≤ 0.005) than in their counterparts. CONCLUSIONS: A declining PA trend among Chinese children aged 6-17 years was observed from 2004 to 2015, and certain subgroups and geographical areas are at higher risk of physical inactivity.

Recent Trends in Physical Activity among Chinese Children Based on Their Demographic and Social Characteristics.

Aimed to explore the trends in physical activity among Chinese children, data of 4,341 children aged 6-17 years who participated in at least one round of "China Health and Nutrition Survey" from 2004 to 2015 were analyzed. Repeated measures mixed models were applied to test the trends in physical activity, which were further analyzed after applying stratification on gender, age, urbanization level, residential area and region. The volume of total physical activity in Chinese children aged 6-17 years showed a downward trend from 2004 to 2015, especially among children residing in medium and high urbanization communities, the south and urban areas of China, so that more efforts need to be put to promote their physical activity.

Resilience-building module for undergraduate nursing students: A mixed-methods evaluation.

In nursing students, resilience is recognised as a critical quality that will enable them to face and solve the challenges encountered in their studies and future careers. This mixed-methods study aimed to develop a resilience-building module for university nursing students and evaluate its effects on resilience, well-being and mindfulness. We recruited a convenience sample of 195 nursing students and delivered a resilience-building module comprising three 90-minute workshops on the following topics: resilience and emotion regulation, stress management and mindfulness, and burnout and depression. The participants' views and perceptions of the module were explored using pre-test and post-test questionnaires and focus group interviews. No significant changes in outcomes were observed from the pre-test to the post-test. However, a multivariable linear regression analysis indicated that mindfulness was significantly associated with resilience. A qualitative data analysis revealed that the resilience-building module evoked the participants' awareness of resilience and was considered an enjoyable learning experience. In conclusion, although the quantitative results demonstrated no significant changes in outcomes after the module, the qualitative results suggested that the resilience-building module could have beneficial effects if included in the undergraduate nursing curricula. Finally, better mindfulness was identified as important for enhancing resilience among undergraduate nursing students.

Knowledge, Attitudes and Practices Towards COVID-19 Amongst Ethnic Minorities in Hong Kong.

This study assessed the knowledge, attitudes and practices (KAP) towards coronavirus disease 2019 (COVID-19) among South Asians in Hong Kong and examined the factors that affect KAP towards COVID-19 in this population. This cross-sectional descriptive study recruited participants with assistance from South Asian community centres and organisations. A total of 352 participants completed questionnaires to assess their level of KAP towards COVID-19. The mean knowledge score was 5.38/10, indicating a relatively low knowledge level. The participants expressed certain misconceptions regarding the prevention of COVID-19 infection. They perceived a mild risk related to the disease, had positive attitudes regarding its prevention and often implemented recommended disease-preventive measures, such as maintaining social distance (88.1%) and wearing masks in public (94.3%). Participants who were male, had a secondary school education or lower and who perceived a lower risk of being infected and lower self-efficacy were less likely to implement preventive measures. Culturally and linguistically appropriate health education could be developed to increase the knowledge of South Asians, especially those with lower education levels, about COVID-19 and to encourage them to implement the necessary preventive measures.
