ABSTRACT
【Objective】 To analyze the relevant studies on blood donor cohort and explore the current research status, research hotspots and development trends of blood donor cohort studies abroad. 【Methods】 Based on the Web of Science Core Collection, the literature related to blood donor cohort was searched. After screening and data processing, bibliometric analysis was carried out from the volume of literature trends, disciplines, authors, institutional distribution and other aspects of the included literature. At the same time, CiteSpace 5.6R5 software was used to carry out visual analysis of countries/regions, literature co-citation, keyword co-occurrence, keyword clustering and keyword emergence. Results A total of 672 papers (654 research papers, 18 review papers) were included. The total number of papers published in the field of blood donor cohort study showed a steady upward trend since 1991, the fastest growth was between 2019 and 2020. The top three cited authors were Kaaks R (1 301 citations), Rinaldi S (1 186 citations) and Riboli E (1 130 citations); the top three institutions were RLUK library in the UK, the University of California and the University of Copenhagen; the top three countries/regions in the volume of literature were the United States (176 papers), Germany (64 papers) and France (54 papers), and they all co-operated closely with other countries. The top five keywords were "blood donor" , "prevalence" , "infection" , "risk" and "antibody" . A total of 19 clusters were obtained by keyword cluster analysis, it was reflected in the immune mechanism and prevalence of blood-borne diseases, the relationship between blood donation behavior and non-communicable disease and its influencing factors, and the classification of the characteristics of blood donors. "Non-hepatitis B" was the keyword with the greatest burst intensity. The keywords that have burst out in recent years and continue to this day include "donation" , "seroprev-alence" , "donor" and "management" . Conclusion At present, the cohort study of blood donors has been paid more and more attention in the world, and its research trends mainly focus on the study of transfusion-transmitted disease risk. However, more researches begin to pay attention to the health problems and influencing factors of blood donors or recipients, which provides the research ideas and directions for establishing cohort study among blood donors in China.
ABSTRACT
Objective Health education resource allocation is one of the basic indicators for evaluating health equity. At present, the research on the equity of health education resource allocation in China is mostly limited to a single year or regional data. This study was aimed to understand the equity of health education resources in the whole China from 2015-2019, and to provide a corresponding basis for further rational allocation of health education resources. Methods The data was obtained based on the number of health education training work, health education publicity work, distribution of health education publicity materials and the annual use of funds carried out mainly by the CDC or health education centers in each province according to the 2016-2020 China Health Statistics Yearbook. The inequality coefficient (Gini coefficient) and Lorenz curve were applied to study the selected data. Results The total number of health education resources in China from 2015-2019 was 1 789 735 and 1 933 336, respectively. The Gini coefficients of health education resource allocation by population distribution were all below the warning line of 0.4, which were in an equitable state. Conclusion The equity of health education resources in China is good according to demographic indicators, and there is no significant inequity. Especially, the aspects of health education services, such as technical consultation and media cooperation, are relatively good, but there is still much room for improvement in the construction of websites.
ABSTRACT
Objective This article takes a cosmetics factory in Yichang City as an example, uses a variety of methodologies to explore methods of health impact assessment and provides methodological references for future health evaluation of related public policies. Methods By analyzing the environmental assessment report of the cosmetic renovation project, an indicator system was established and expert consultation meetings were conducted to score the impact of the corresponding indicators on health. The impact of the renovation project of the factory on the factory workers, surrounding residents and the sustainable development of the environment was analyzed by means of the Kaiser model with the risk matrix and the Borda value. Results The risk values of the five influencing factors of industrial wastewater, domestic wastewater, industrial waste gas, industrial waste and noise were 5.11%, 5.43%, 10.6%, 6.71% and 7.02% respectively. All the influencing factors were in the green zone of the risk matrix. The Borda values of the five influencing factors of industrial waste water, domestic waste water, industrial waste gas, industrial waste residue and noise were 4, 5, 10, 7 and 5 respectively. Conclusion The multiple methodologies adopted in the factory renovation project are feasible, and can provide new ideas for the health impact assessment of public policies in the future.
