Proper motivation of volunteers is required for sustaining volunteer performance, while encumbrances to optimal engagement in health systems need to be addressed. This study aimed to investigate the main factors that motivate volunteers to participate in the UAE healthcare system, along with exploring the barriers and challenges being faced. Methods: This study was designed as a quantitative cross-sectional study in United Arab Emirates (UAE). A purposive sample of the Adult citizens and residents using purposive sampling directed at all major health volunteer recruitment agencies in UAE, who have volunteered at least once in the health system over the preceding 12 months. Participants Adult UAE residents were selected by a purposive sampling method from February to April 2017. Data were collected through electronic questionnaires using modified Volunteer Motivation Inventory (VMI). Data were analyzed from 667 adults’ residents who were reported to volunteer at least once in healthcare opportunities. Results: About 53% (n = 290) of the volunteers in this sample were full time employed individuals. Almost 63% (n = 422) were female. Overall, assessed self-reported motivations of volunteer participants were high. The main motivation for volunteering in healthcare opportunities in the UAE was Understanding dimension (Mean = 4.68), followed by self-esteem dimension (Mean = 4.60). Eight elements of volunteer motivation showed no statistically significant differences between male and female respondents. Organization/system barriers dimension was the highest among respondents (Mean = 2.9), followed by individual barriers (Mean = 2.6), interpersonal (Mean = 2.06) and contextual (Mean = 2.04). Conclusion: UAE health sector volunteers who participated in this study appeared to be highly motivated. The main motivation factor was understanding dimension which allowed volunteers in healthcare to gain a new perspective on things, through practical training and learning new things, dealing with different groups in the health sector, for example doctors, nursing, patients. What makes the health sector volunteer understand them self and the world around them. Therefore the organization should focus on volunteer motivation to ensure future intensions of them. The four main barriers to volunteer were Individual barriers, Interpersonal barriers, contextual barriers and organizations system barriers. Concerted efforts are needed to raise awareness about available volunteer opportunities, and optimally align the motivations of volunteers with organizational objectives in the UAE health sector.展开更多

Therefore, this activity fits into principles of sustainable development which has been defined as growth based on a balance between the environmental, social, and economic dimensions. The aim of this study was to determine the contribution of volunteering tourism to sustainable development and to identify the crucial factors to implement a successful volunteering project. We explored the interactions between volunteering tourism and sustainable development through a qualitative approach considering as case study: the rural tourism project “Quilla Pacari”, located in the highlands of Chimborazo province, Ecuador. Our findings proportionate information about the influence of volunteering tourism in principles associated with sustainable development revealing a general insight into the interactions and identifying the perception about the crucial factors to implement a successful volunteering project. However, the Quilla Pacari project located in Chimborazo province is relatively emergent and further studies are needed to clarify all the relations associated with the process.展开更多

Patients and methods: Our study population consisted of all volunteer blood donors who had donated during a 2-year period from 1 January 2019 to 31 December 2020. Samples were taken from patients with no contraindications and serological tests were performed using ELISA tests. HBsAg, HCV-Ac and HIV serology were tested. All samples reactive for HIV, HBV and HCV were retested for confirmation using a second enzyme-linked immunosorbent assay. A result was considered positive if both the first and second tests were positive. Results: In two years, the Ouahigouya BSDD recorded 9726 donations, including 7983 new donors and 1743 former donors. The average age of donors was 25.59 years, with a sex ratio of 3.4. The seroprevalence of HBV, HCV and HIV was 7.31%, 3.10% and 2.12% respectively. HBV-HCV co-infection was found in 0.32% of cases, HIV-HBV, HIV-HCV, and HIV-HBV-HCV co-infection were found in 0.25%, 0.09% and 0.04% respectively. Conclusion: The seroprevalence of viral hepatitis B and C remains high among volunteer blood donors in Ouahigouya, although a decline in seroprevalence appears to be on the horizon.展开更多

We conducted a longitudinal study of 4304 sperm donors from the Guangdong Provincial Human Sperm Bank (Guangzhou, China) during 2017–2021. A body composition analyzer was used to measure total and local body fat percentage for each participant. Generalized estimating equations were employed to assess the association between body fat percentage and sperm count, motility, and morphology. We estimated that each 10% increase in total body fat percentage (estimated change [95% confidence interval, 95% CI]) was significantly associated with a 0.18 × 106 (0.09 × 106–0.27 × 106) ml and 12.21 × 106 (4.52 × 106–19.91 × 106) reduction in semen volume and total sperm count, respectively. Categorical analyses and exposure-response curves showed that the association of body fat distribution with semen volume and total sperm count was stronger at higher body fat percentages. In addition, the association still held among normal weight and overweight participants. We observed similar associations for upper limb, trunk, and lower limb body fact distributions. In conclusion, we found that a higher body fat distribution was significantly associated with lower semen quality (especially semen volume) even in men with a normal weight. These findings provide useful clues in exploring body fat as a risk factor for semen quality decline and add to evidence for improving semen quality for those who are expected to conceive.展开更多

文摘Extensive studies have identified potential adverse effects on semen quality of obesity, based on body mass index, but the association between body fat distribution, a more relevant indicator for obesity, and semen quality remains less clear. We conducted a longitudinal study of 4304 sperm donors from the Guangdong Provincial Human Sperm Bank (Guangzhou, China) during 2017–2021. A body composition analyzer was used to measure total and local body fat percentage for each participant. Generalized estimating equations were employed to assess the association between body fat percentage and sperm count, motility, and morphology. We estimated that each 10% increase in total body fat percentage (estimated change [95% confidence interval, 95% CI]) was significantly associated with a 0.18 × 106 (0.09 × 106–0.27 × 106) ml and 12.21 × 106 (4.52 × 106–19.91 × 106) reduction in semen volume and total sperm count, respectively. Categorical analyses and exposure-response curves showed that the association of body fat distribution with semen volume and total sperm count was stronger at higher body fat percentages. In addition, the association still held among normal weight and overweight participants. We observed similar associations for upper limb, trunk, and lower limb body fact distributions. In conclusion, we found that a higher body fat distribution was significantly associated with lower semen quality (especially semen volume) even in men with a normal weight. These findings provide useful clues in exploring body fat as a risk factor for semen quality decline and add to evidence for improving semen quality for those who are expected to conceive.
文摘Background:Oral health issues persistently affect the overall health and well-being of rural populations.Village health volunteers(VHVs)play a crucial role in advancing oral health literacy in their community.This study aimed to examine the factors related to nutritional literacy for oral health among VHVs.Methods:This was a mixed-methods study employing an explanatory sequential design.The quantitative data were gathered through questionnaires distributed to a cohort of 10,514 VHVs registered in Health Region 1.A stratified random sampling technique was used to ensure adequate representation of various subgroups within the VHV population,considering factors such as age,education level,and geographical distribution across the region.This approach allowed for a more representative sample that accurately reflects the diversity of the VHV population.Qualitative data were obtained through semi-structured interviews with a purposive sampling of 20 participants based on specific criteria.Quantitative data were analyzed using descriptive statistics and biserial correlation techniques,while qualitative data were analyzed using content analysis.Results:The study found that the sample group possessed a moderate level of knowledge of health literacy principles and nutrition for oral health.However,their self-assessed skills in nutritional literacy for oral health were rated as high.A statistically significant negative correlation was found between knowledge of nutrition for oral health and skills in nutritional literacy for oral health.VHVs equated health literacy with knowledge because their public health training had focused more on imparting knowledge rather than developing skills based on health literacy principles.Conclusion:There is a need to emphasize skill-based health literacy training and to use effective skill development techniques that are tailored to the specific roles and responsibilities of health volunteers.It is also recommended to continuously monitor and evaluate the outcomes of these efforts.

文摘Assessing regional economic development is key for advancing towards the Sustainable Development Goals and ensuring sustainable societal progress.Traditional evaluation methods focus on basic economic metrics like population and capital,which may not fully reflect the complexities of economic activities.Nighttime light(NTL)has been validated as an alternative indicator for regional economic development,yet limitations persist in its evaluation.This study integrates OpenStreetMap(OSM)data and NTL data,providing a novel data integration approach for evaluating economic development.The study uses mainland of China as a case,applying ordinary least squares(OLS)and geographically weighted regression(GWR)to evaluate OSM and NTL data across provincial,municipal,and county levels.It compares OSM,NTL,and their combined use,providing key empirical insights for enhancing data fusion models.The study results reveal:(1)NTL data is more accurate for provincial-level economic activity,while OSM data excels at the county level.(2)GWR demonstrates superior capability over OLS in revealing the spatial dynamics of economic development across scales.(3)Through the integration of both datasets,it is observed that,compared to single-data modeling,the performance is enhanced at the city scale and county scale.The study demonstrates that combining OSM and NTL data effectively assesses economic development in both developed and underdeveloped areas at provincial,municipal,and county levels.The study offers a straightforward and efficient approach to data integration.The findings offer new research perspectives and scientific support for sustainable regional economic growth,particularly valuable in data-scarce,underdeveloped areas.
