Associations of sugar-sweetened beverage consumption and screen time with physical fitness index: a multicentre cross-sectional study among Chinese adolescents

BackgroundPast research has focused on the analysis of the association between sugar-sweetened beverages consumption and screen time, respectively, and an indicator of physical fitness in adolescents. However, no studies have analyzed the interaction between sugar-sweetened beverage consumption and screen time on physical fitness index.MethodsDemographic information, lifestyle, sugar-sweetened beverage consumption and screen time were investigated and physical fitness indicators were tested in 8136 adolescents aged 13–18 years from six geographic regions of China using stage-stratified whole population sampling. The chi-square test and one-way ANOVA were used to compare the covariates. The Kruskal-Wallis test was used to compare physical fitness index between different sugar-sweetened beverage consumption and screen time groups. Generalized linear model ordered logistic regression analysis was used to analyze the interaction between sugar-sweetened beverage consumption and ST on physical fitness index.ResultsThe differences in physical fitness index among different sugar-sweetened beverage consumers in child adolescents were all statistically significant in boys, girls, and in total (H-value of 72.415, 16.859, and 78.544, P < 0.001). The differences were also statistically significant when comparing the physical fitness index of Chinese adolescents of different screen time in boys, girls, and total (H-Value of 46.307, 21.552, and 65.287, P < 0.001). Overall, using sugar-sweetened beverage consumption ≤ 1time/week and screen time < 60 min/d as the reference group, after adjusting for relevant covariates, adolescents in the group with an sugar-sweetened beverage consumption of ≥ 5 time/week and screen time > 120 min/d (OR = 2.27, 95% CI:1.78, 2.89) had the the highest risk of reduced physical fitness index (P < 0.001 ).ConclusionAssociations of sugar-sweetened beverage consumption and screen time with physical fitness indices among Chinese adolescents. Both increased sugar-sweetened beverage consumption and prolonged ST further increased the risk of lower physical fitness index in adolescents.

Numerical study on parametric correlations and regional applicability of a cross-flow indirect evaporative cooler

The indirect Evaporative Cooler (IEC) utilizes exhaust air from air-conditioned spaces to precondition outdoor air, offering a low-carbon and efficient solution for cooling the air and expanding its application scope. This study developed a mathematical model of IEC, considering the effects of primary air condensation and channel wettability. The correlations of eight parameters on evaluation indexes were analyzed to rank their influence for IEC, revealing that outdoor climate, indoor air conditions, geometric shape, and channel wettability are the main factors affecting cooling efficiency and energy recovery capacity. Subsequently, a comparison of the temperature and humidity distribution inside the IEC under high and low wettability showed that under high-wettability, the cooling effect of the IEC for primary air increased by 23.7 %, and the dehumidification capacity improved by 52.9 %. The performance study of the IEC across seven geographical regions in China indicates that cities with a wet-bulb efficiency greater than 45 % are predominantly located in Northwest China and North China. East China, Central China, and South China exhibit significantly higher average condensation coefficients and cooling capacities compared to other areas, with values of 2.36, 2.26, and 2.56 for the condensation coefficients, and 14.2 kW, 14.7 kW, and 14.9 kW for the cooling capacities, respectively.

Music Characteristics and Regional Differences in (SHE) Ethnic Minority Folk Songs: A Comparative Analysis of Ningde and Eastern Fujian Regions

Tucked away in the stunning province of Fujian in southeast China, the region has a cultural tapestry as varied and vibrant as its breath-taking scenery. Through the analysis and coding of folk songs from four different geographical regions in China (Fujian and Ningde), this paper aimed to determine the degree of mutual interaction and integration of the musical cultures of the Shen and Han nationalities into modernity. It did this by developing a new musical characteristic density map for machine music classification. The nationality known as (SHE) is a small ethnic group in the area. The traditional cultural heritage as well as the growth of the (SHE) nationality have lagged behind the rapid advancement of modern times. This study investigates how to incorporate the culture of the (SHE) nationality into modern culture in order to fully realise the goal of "going out," starting from the conventional cultural heritage and creative growth of the (SHE) nationality. This paper discusses the formation of the (SHE) Minority folk songs in the context of protecting intangible cultural heritage. It does this by using the methods of literature research, field investigation, and comprehensive analysis to gather first-hand fresh field data from the components of historical evolution, protection process, inheritance method, development dilemma, and countermeasures. Questions of development and inheritance. The world will recognise the allure of the traditional culture of the (SHE) nationality as it is continuously enhanced and vibrant.

Latent profile analysis of empathy ability and its relationship with professional quality of life among hospice nurses in China

BackgroundEmpathy is important in hospice nursing clinics and may influence nurses’ professional quality of life (ProQOL). However, present studies ignoring each empathic dimension, and few researches have explored the correlation between empathy and ProQOL in hospice nurses in Asia. To better understand hospice nurses’ empathy abilities in China and its relationship with ProQOL, the aim of this study was to identify the latent profiles and its influencing factors of hospice nurses’ empathy ability, as well as differences in ProQOL across each latent profile.MethodsA cross-sectional study was conducted from October 2021 to September 2022, and a total of 725 hospice nurses were recruited from different geographic regions in China. Participants completed the Empathy Ability Scale for Hospice Nurses and the Brief Professional Quality of Life Scale. Latent profile analysis (LPA) was employed to identify latent profiles of empathy ability among hospice nurses in China. The predictors of hospice nurses’ empathy ability in different latent profiles were assessed using multinomial logistic regression analysis. One-way ANOVA test and the Kruskal–Wallis test were used to compare the ProQOL scores in each latent profile of nurses’ empathy ability.ResultsThis study identified three latent profiles of hospice nurses’ empathy ability, and those profiles labelled “poor empathy ability-high surface empathy expression” (n = 216, 29.8%), “moderate empathy ability” (n = 359, 49.5%) and “high empathy ability-high deep empathy expression” (n = 150, 20.7%). Multinomial logistic regression analysis suggested that age, hospital level, whether income meets expectations, interests in hospice care work, hospice work experience, and receiving psychological counselling were predictors of hospice nurses’ profile membership of empathy ability. The scores of compassion satisfaction (CS) and burnout (BO) in ProQOL were significantly different across each profile (P < 0.001), while scores of secondary traumatic stress (STS) in ProQOL were not different across each profile (P = 0.294).ConclusionsHospice nurses’ empathy ability was divided into three latent profiles, and enhancing empathy ability may be conducive to improving hospice nurses’ CS, while reducing BO, thus fostering their overall quality of life. Nursing managers should identify hospice nurses at higher risk of BO and implement targeted interventions focused on enhancing nurse’s empathy abilities.

Ambient air pollution contributed to pulmonary tuberculosis in China

ABSTRACT Published studies on outdoor air pollution and tuberculosis risk have shown heterogeneous results. Discrepancies in prior studies may be partially explained by the limited geographic scope, diverse exposure times, and heterogeneous statistical methods. Thus, we conducted a multi-province, multi-city time-series study to comprehensively investigate this issue. We selected 67 districts or counties from all geographic regions of China as study sites. We extracted data on newly diagnosed pulmonary tuberculosis (PTB) cases, outdoor air pollutant concentrations, and meteorological factors in 67 sites from January 1, 2014 to December 31, 2019. We utilized a generalized additive model to evaluate the relationship between ambient air pollutants and PTB risk. Between 2014 and 2019, there were 172,160 newly diagnosed PTB cases reported in 67 sites. With every 10-μg/m3 increase in SO2, NO2, PM10, PM2.5, and 1-mg/m3 in CO, the PTB risk increased by 1.97% [lag 0 week, 95% confidence interval (CI): 1.26, 2.68], 1.30% (lag 0 week, 95% CI: 0.43, 2.19), 0.55% (lag 8 weeks, 95% CI: 0.24, 0.85), 0.59% (lag 10 weeks, 95% CI: 0.16, 1.03), and 5.80% (lag 15 weeks, 95% CI: 2.96, 8.72), respectively. Our results indicated that ambient air pollutants were positively correlated with PTB risk, suggesting that decreasing outdoor air pollutant concentrations may help to reduce the burden of tuberculosis in countries with a high burden of tuberculosis and air pollution.

Development of Reliable Male-Specific Molecular Markers for Genetic Sex Identification in Sea Cucumber Apostichopus japonicus.

Apostichopus japonicus is an important marine aquaculture species in China, with high nutritional and economic value. In A. japonicus, there is no obvious sexual dimorphism in external appearance, and sex differentiation primarily relies on the observation of mature gonads after dissection, which leads to difficulties in sex identification. The confusion in sex identification greatly reduces breeding efficiency in the sea cucumber industry. Therefore, developing a reliable sex-specific marker is crucial. In this study, we identified 586 male-specific sequences through whole-genome assembly and sequence alignment, but did not identify any female-specific sequences, inferring an XY-type sex determination system in sea cucumbers. We developed a set of male-specific molecular markers to establish an accurate, stable, and widely adaptable genetic sex identification technique for A. japonicus. The male-specific molecular markers were validated with 100% accuracy in sea cucumber populations from six different geographical regions in China. In conclusion, this study provides further evidence for the XY-type sex determination system in A. japonicus and establishes an effective genetic sex identification method for multi-geographic populations, which benefits future study on reproductive biology and has significant implications in sea cucumber aquaculture industry.

Distribution and Drug Resistance Characteristics of Pathogenic Bacteria in the Elderly Population in China in 2021

To study the distribution and drug resistance characteristics of pathogenic bacteria in the elderly population of China by collecting and analyzing the standardized case data on the pathogens of infections in elderly patients, and to facilitate the establishment of a standardized layered surveillance system for pathogenic bacteria in China. We collected the case data of elderly patients (≥65 years old) from 62 sentinel hospitals across the country in 2021. Then, we statistically analyzed the data by patient age, their geographical region, the distribution of pathogenic bacteria, and the drug resistance characteristics of main pathogens. A total of 3468 cases from across the country were included in the study. The top three sources of patients were the intensive care unit (13.2%), the department of respiratory medicine (11.2%), and the department of general surgery (8.4%). The top three types of specimens were urine (25.5%), sputum (20.6%), and blood (18.7%). A total of 3468 strains of pathogens were isolated, among which, 78.9% were gram-negative bacteria and 21.1% were gram-positive bacteria. The top five types of bacteria were Escherichia coli (20.9%), Klebsiella pneumoniae (18.3%), Pseudomonas aeruginosa (11.2%), Staphylococcus aureus (9.0%), and Acinetobacter baumannii (7.0%). The isolation rates of common important drug-resistant bacteria were 38.0% for methicillin-resistant Staphylococcus aureus (MRSA), 68.7% for carbapenem-resistant Acinetobacter baumannii (CRAB), and 38.2% for carbapenem-resistant Pseudomonas aeruginosa (CRPA), 20.1% for carbapenem-resistant Klebsiella pneumoniae (CRKP), 5.2% for carbapenem-resistant Escherichia coli (CRECO), and 2.1% for vancomycin-resistant Enterococcus (VRE). There were differences in the isolation rates of CRAB and CRKP in clinical care in the elderly population in seven geographical regions of China (P<0.05). Klebsiella pneumoniae is the most important pathogen in the elderly population ≥85 years old, and the isolation rates of CRKP showed significant differences in different age groups (P<0.05). There are significant differences in the drug resistance of pathogenic bacteria in the elderly populations of different regions and age groups in China. Therefore, monitoring the distribution and drug resistance of pathogenic bacteria in the elderly population and formulating targeted treatment plans according to the characteristics of the specific regions and age groups are of great significance to the improvement in the treatment outcomes and prognosis of the elderly population.

Analysis of the associations between moderate-to-vigorous physical activity and screen time on psychological symptoms among university students: a cross-sectional survey based on six geographic regions in China

BackgroundDeclining physical activity and increasing screen time (ST) among Chinese adolescents have become major concerns shared by scholars, while mental health issues are also on the rise. Previous studies have confirmed the association between physical activity and screen time and psychological symptoms, but it is unclear how their psychological symptoms, especially for Chinese university students who have a high proportion of psychological symptoms, and no research evidence has been found.MethodsThis study investigated physical activity, screen time, and psychological symptoms in 11,173 university students aged 19–22 years in six regions of China. A binary logistic regression analysis was used to analyze the association between moderate-to-vigorous physical activity (MVPA) and screen time and psychological symptoms. And the generalize linear model (GLM) analysis was used to further analyze the association between MVPA and screen time and psychological symptoms.ResultsThe detection rate of psychological symptoms among Chinese university students was 16.3%, with a higher percentage of female students (17.5%) than male students (14.7%). The proportion of male students (8.2%) with MVPA > 60 min/d was higher than that of female students (2.3%), and the proportion of male students (33.8%) and female students (34.5%) with screen time > 2 h/d was basically the same. The generalize linear model (GLM) analysis showed that university students with MVPA < 30 min/d and screen time > 2 h/d (OR = 1.59, 95% CI: 1.10–2.31) had the highest risk of psychological symptoms (OR = 1.59, 95% CI: 1.10–2.31) compared to university students with MVPA > 60 min/d and screen time < 1 h/d as the reference group. The risk of psychological symptoms was the highest among those with MVPA < 30 min/d and screen time > 2 h/d (OR = 1.59,95% CI: 1.10–2.31). In addition, university students with MVPA > 60 min/d and a screen time of 1–2 h/d (OR = 0.09, 95% CI: 0.03–0.25) had the lowest risk of psychological symptoms (P < 0.001). The same trend was observed for both male and female students.ConclusionChinese university students have a certain proportion of psychological symptom problems, and there is a significant between MVPA and screen time and psychological symptoms, and the same trend exists for both male and female students. Chinese university students should perform MVPA for not less than 60 min a day, and at the same time control the duration of screen time, and screen time should be controlled between 1 and 2 h a day, which has a better promotion effect on psychological health.

To conduct timely surveillance of the seasonal characteristics and disease burden of Human Respiratory Syncytial Virus (HRSV) in various geographical regions of China, and further develop more precise and effective prevention and intervention strategies, there is an urgent need for China to establish a nationwide, effective, and stable HRSV surveillance system. Through combining the current status of domestic and international HRSV surveillance systems and the existing surveillance framework in China, this study proposed an HRSV surveillance type applicable to China based on different surveillance purposes, and considering the feasibility of implementation. This article aimed to provide solid scientific and technical support to monitor the dynamic changes of HRSV epidemic timely, carry out a risk assessment and early warning, and further understand the disease burden of HRSV in China. It also helps to improve the diagnosis, prevention, and control of the HRSV diseases research and development, use, and evaluation of HRSV vaccines and drugs in China.

Exploring the spatial-temporal evolution characteristics of extreme heat events and driving factors in seven geographic regions of China (1980–2021)

Extreme heat events in China are occurring more frequently due to global warming. However, there is a lack of comprehensive studies analyzing the movement direction and factor interaction of extreme heat events in different regions of China. Based on daily temperature data from 2252 meteorological stations in China from 1980 to 2021, three extreme heat indicators were calculated: Hot days (SU35), Tropical nights (TR20), and Extreme maximum temperature (TXx). The study updated and compared the characteristics of spatiotemporal evolution and driving factors of extreme heat events in China and its seven geographical regions.The results show that: (1) SU35 and TR20 increase faster in summer, while TXx increases faster in winter. Nighttime high-temperature events have increased at a faster rate. (2) Extreme heat events in North, Northeast, and Northwest China have gradually moved southward and eastward, while in Central, East, and South China, such events have moved northward. (3) In northeast and northwest China, the Atlantic Multi-decadal Oscillation (AMO) is a strong driving force for extreme heat events, while urbanization is the most potent driving force in the remaining regions. The interaction between urbanization and atmospheric circulation, including AMO, Pacific Decadal Oscillation (PDO), and East Atlantic/West Russia (EA/WR), is non-linear or double factor enhancement and exhibits significant spatial heterogeneity. These results will be significant for urban adaptation to climate change and sustainable development.

A study on the physical aging characteristics of the older people over 70 years old in China.

In China, with the increase of life expectancy and the decrease of fertility rate, the aging problem has become increasingly prominent, and the physical problems of the older people over 70 years are the key and difficult problems. Based on the interactive logic between the aging problem and the older people health, in the study, a questionnaire survey and a nationwide physical fitness test were carried out on the older people over 70, to divide into different age groups (70-74 years old, 75-79 years old, 80-84 years old, 85 years old and older) and different genders. There were 8,400 valid samples, and 1,050 persons in each group. One-way ANOVA was used to compare the differences among groups of different ages, and a broken line chart was drawn to discuss the aging characteristics of various physical indexes of the older people over 70 in China. (1) Body morphology: male waist circumference, male waist-to-height ratio and female BMI showed a gradual downward trend with the increase of age; (2) Physiological function: male and female vital capacity showed a decreasing trend with the increase of age, while female pulse pressure showed a gradual upward trend. (3) Physical quality: the indicators of male and female muscle strength, flexibility quality, aerobic endurance and balance showed a downward trend with the increase of age. Vital capacity, flexibility quality, muscle strength, aerobic endurance, balance ability and so on, decreased significantly with the growth of age. 80 years old is the inflection point of the rapid decline of various indicators. Blood pressure, silent pulse, BMI, waist-to-hip ratio, waist-to-height ratio and other indicators did not change regularly with age. Indicators such as blood pressure, BMI, waist-to-hip ratio and waist-to-height ratio were in the high-risk range of metabolic diseases and cardiovascular and cerebrovascular diseases. The study conducted physical fitness test on the older people over 70 years old in 7 geographical regions of China, which is the first nationwide physical fitness test for the older people, which is an extension and expansion of the national physical fitness monitoring system, and also shows that the test indicators involved in the "Health fitness scale" are simple and feasible. And the study added a series of test data over 70 years old, which is the basis for scientific and reasonable formulation of physical fitness evaluation standards for the older people, and is of great significance for improving the national physical fitness database and grasping the dynamic changes of national physical health status, and providing data support for scientific guidance of physical exercise for the older people.

Application of improved glomerular filtration rate estimation by a neural network model in patients with neurogenic lower urinary tract dysfunction.

Previous studies have indicated that creatinine (Cr)-based glomerular filtration rate (GFR) estimating equations - including the new Chronic Kidney Disease Epidemiology creatinine (CKD-EPIcr) equation without race and the estimated glomerular filtration rate (eGFR) equation developed for the Chinese population - displayed suboptimal performance in patients with neurogenic lower urinary tract dysfunction (NLUTD), which limited their clinical application for detecting changes in GFR levels in all cohorts. To develop a neural network model based on multilayer perceptron (MLP) for evaluating GFR in Chinese NLUTD patients, and compare the diagnostic performance with Cr-based multiple linear regression equations for Chinese and the CKD-EPIcr equation without race. Single-center, cross-sectional study of GFR estimation from serum Cr, demographic data, and clinical characteristics in Chinese patients with NLUTD. A total of 204 NLUTD patients, from 27 different geographic regions of China, were selected. A random sample of 141 of these subjects was included in the training sample set, and the remaining 63 patients were included in the testing sample set. The reference GFR (rGFR) was assessed by the technetium-99m-labeled diethylenetriaminepentaacetic acid (99mTc-DTPA) double plasma sample method. A neural network model based on MLP was developed to evaluate GFR in the training sample set, which was then validated in the testing sample set and compared with Cr-based GFR equations. The MLP-based model showed significant performance improvement in evaluating the difference, absolute difference, precision, and accuracy of GFR estimation compared with the Cr-based GFR equations. Additionally, compared with the rGFR, we found that the MLP-based model provided an acceptable level of accuracy (greater than 85%, which was within a 30% deviation from the rGFR). The MLP-based model offered significant advantages in estimating GFR in Chinese NLUTD patients, and its application could be suggested in clinical practice.

Genomic analysis of lumpy skin disease virus asian variants and evaluation of its cellular tropism

Lumpy skin disease virus (LSDV) is a poxvirus that mainly affects cattle and can lead to symptoms such as severe reduction in milk production as well as infertility and mortality, which has resulted in dramatic economic loss in affected countries in Africa, Europe, and Asia. In this study, we successfully isolated two strains of LSDV from different geographical regions in China. Comparative genomic analyses were performed by incorporating additional LSDV whole genome sequences reported in other areas of Asia. Our analyses revealed that LSDV exhibited an ‘open’ pan-genome. Phylogenetic analysis unveiled distinct branches of LSDV evolution, signifying the prevalence of multiple lineages of LSDV across various regions in Asia. In addition, a reporter LSDV expressing eGFP directed by a synthetic poxvirus promoter was generated and used to evaluate the cell tropism of LSDV in various mammalian and avian cell lines. Our results demonstrated that LSDV replicated efficiently in several mammalian cell lines, including human A549 cells. In conclusion, our results underscore the necessity for strengthening LSD outbreak control measures and continuous epidemiological surveillance.

Chinese Snowscape As a Phenomenon

With unique aesthetic value, snowy landscapes are one of the most important subjects in Chinese painting. Due to their purity, elegance, serenity, simplicity and cold charm, snow scenes have been the focus of artists and scholars from long ago. The artistic features and cultural connotations of Chinese snow paintings have attracted the attention of many Chinese and Russian scholars. However, there is no typological study of snow landscape in their works. In this regard, the authors consider it necessary to actualize this topic. The article provides historical information about the study of snowy landscape, the history of Chinese painting masters’ appeal to this theme. The classification of snow painting depending on seasons, geographical regions of China, atmospheric phenomena, and themes is offered. The authors suggest their definition of the concept of “Chinese snow landscape” and the author’s classification of the content of snow paintings. The paper applies a typological approach to the analysis of “snow” scenes, and examines the development of traditional Chinese aesthetic contexts from ancient artistic codes to contemporary theories. Outstanding examples of snow landscape painting are presented. Snow painting is an important medium of Chinese cultural heritage that demonstrates the diversity and richness of Chinese culture. The given overview of China’s snow scene painting as a phenomenon in the work of Chinese artists can serve as a basis for further in–depth studies.

Preliminary Retrieval and Validation of Aerosol Optical Depths from FY-4B Advanced Geostationary Radiation Imager Images

Fengyun-4B (FY-4B) is the latest Chinese next-generation geostationary meteorological satellite. The Advanced Geostationary Radiation Imager (AGRI) aboard FY-4B is equipped with 15 spectral bands, from visible to infrared, suitable for aerosol optical depth (AOD) retrieval. In this study, an overland AOD retrieval algorithm was developed for the FY-4B AGRI. Considering the large directional variation in the FY-4B AGRI reflectances, a bidirectional reflectance distribution function (BRDF) database was built, through which to estimate land surface reflectance/albedo. Seasonal aerosol models, based on four geographical regions in China, were developed between 2016 and 2022 using AERONET aerosol products, to improve their applicability to regional distribution differences and seasonal variations in aerosol types. AGRI AODs were retrieved using this new method over China from September 2022 to August 2023 and validated against ground-based measurements. The AGRI, Advanced Himawari Imager (AHI), and Moderate-Resolution Imaging Spectroradiometer (MODIS) official land aerosol products were also evaluated for comparison purposes. The results showed that the AGRI AOD retrievals were highly consistent with the AERONET AOD measurements, with a correlation coefficient (R) of 0.88, root mean square error (RMSE) of 0.14, and proportion that met an expected error (EE) of 65.04%. Intercomparisons between the AGRI AOD and other operational AOD products showed that the AGRI AOD retrievals achieved better performance results than the AGRI, AHI, and MODIS official AOD products. Moreover, the AGRI AOD retrievals showed high spatial integrity and stable performance at different times and regions, as well as under different aerosol loadings and characteristics. These results demonstrate the robustness of the new aerosol retrieval method and the potential of FY-4B AGRI measurements for the monitoring of aerosols with high accuracy and temporal resolutions.

Specifically, the PENG ZU cohort aims to identify and validate multidimensional aging markers, uncover the underlying mechanisms of systemic aging and functional decline, and develop novel strategies and measures to delay functional decline and adverse health outcomes, while maintaining overall good health. The PENG ZU cohort consists of 26,000 individuals aged 25 to 89 years from seven major geographical regions in China. Diversified data and biospecimens are collected according to standardized procedures at baseline and follow-up visits. Baseline recruitment for the PENG ZU cohort was completed in October 2021. The extensive analysis of multidimensional health-related data and bioresources collected from the cohort is anticipated to develop methods for evaluating functional status and elucidating multilevel, cross-scale interactions and regulatory mechanisms of healthy aging. The findings from this study will enhance the understanding of health changes due to aging, facilitate efficient and effective interventions to maintain functional ability, and reduce the incidence and severity of age-related diseases, thereby further promoting healthy aging.

OP143 Association Of Different Venous Access Device With Health‑Related Quality Of Life Among Patients With Breast Cancer In China

IntroductionFew studies have explored the relationship between different venous access devices and health-related quality of life (HRQoL) among patients with breast cancer in China. This study aimed to evaluate the HRQoL of patients with breast cancer in China who underwent different venous access devices and to estimate the association between type of venous access device and HRQoL.MethodsA multicenter cross-sectional study was conducted in three tertiary hospitals from three major geographical regions in China. The final sample consisted of 472 patients aged from 18 to 78 years. The HRQoL was measured with the EQ-5D-5L scale and the EuroQoL Group visual analog scale. The venous access devices were divided into totally implantable venous access devices (TIVAD), peripherally inserted central catheters (PICC), and other devices. The multivariate regression analyses were used to explore the association between type of venous access device and HRQoL.ResultsOf 472 participants, 352 (75%) used the TIVAD device, 89 (19%) used the PICC device, and 31 (7%) used other devices. The TIVAD group had the highest EQ-5D-5L values (mean 0.89, standard deviation [SD] 0.178), while the PICC group had the lowest values (mean 0.85, SD 0.239). The EQ-5D-5L values for the other venous access device group was in between (mean 0.88, SD 0.127). However, the multivariate analysis indicated that the VAS and EQ-5D-5L scale dimension scores among patients were not significantly different (P&gt;0.05) for the various central venous access devices.ConclusionsThis study demonstrates a non-significant association between the type of venous access device used and the HRQoL of patients with breast cancer in China. Although patients with a TIVAD experienced more pain during device insertion and access for chemotherapy, the negative effect on HRQoL scores was smaller than for PICCs.
