Historically, low-and middle-income countries have been scarce producers of biomedical research; only 2% of the global scientific output is produced by these countries despite accounting for 92% of the global burden of disease. In addition, few low-and middle-income countries have exhaustively mapped and analyzed their scientific production in health and its association with main local burden of disease.
To evaluate the evolution of biomedical research in Ecuador over the last 100 years and its relationship with the main causes of mortality.
A bibliometric study embedded in a systematic review design was carried out using biomedical publications indexed in Scopus and Web of Science (WoS) during the period 1920-2021. Information from the National Institute of Statistics and Census was used to identify the main causes of mortality.
Our search strategy identified 16,697 publications related to biomedicine in Ecuador. Of these 3,225 articles met the criteria for this study. Since 2010, there has been an exponential increase in scientific production in biomedicine. This increase was predominantly based on cross-sectional observational studies (49.67%). During the period analyzed (1920-2021), biomedical production was distributed with 52.43% in clinical research, 37.79% in public health, and 9.77% in basic sciences. The research focus with the highest number of publications was epidemiology and surveillance system of diseases (23.44%). Additionally, private universities are the largest producers of biomedical research compared to public universities, 40.12% vs. 19.60%, respectively. Of the total biomedical research produced, 18.54% is associated with the main causes of mortality, and the Ecuadorian private university is the largest contributor to these studies compared to public universities, 39.97% vs. 16.72%.
In one century, Ecuador produced 3,225 articles in biomedicine, according to our criteria. 18.54% of the total produced is aimed at solving the main causes of mortality in the country. Private universities are the leaders in scientific production related to health in Ecuador.
从历史上看，低收入和中等收入国家一直是生物医学研究的稀缺生产者；尽管这些国家承担了全球92%的疾病负担，但它们仅产出了全球2%的科研成果。此外，很少有低收入和中等收入国家全面绘制并分析其卫生领域的科研产出及其与当地主要疾病负担的关联。
评估厄瓜多尔过去100年生物医学研究的发展及其与主要死亡原因的关系。
采用文献计量学研究并嵌入系统评价设计，使用Scopus和科学网（WoS）中索引的1920年至2021年期间的生物医学出版物。利用国家统计和普查研究所的信息来确定主要死亡原因。
我们的检索策略识别出厄瓜多尔16,697篇与生物医学相关的出版物。其中3225篇文章符合本研究标准。自2010年以来，生物医学科研产出呈指数增长。这种增长主要基于横断面观察性研究（49.67%）。在分析期间（1920 - 2021年），生物医学产出分布为临床研究占52.43%，公共卫生占37.79%，基础科学占9.77%。出版物数量最多的研究重点是疾病的流行病学和监测系统（23.44%）。此外，与公立大学相比，私立大学是生物医学研究的最大生产者，分别为40.12%和19.60%。在所有生物医学研究产出中，18.54%与主要死亡原因相关，与公立大学相比，厄瓜多尔私立大学是这些研究的最大贡献者，分别为39.97%和16.72%。
根据我们的标准，厄瓜多尔在一个世纪内产出了3225篇生物医学文章。总产出的18.54%旨在解决该国的主要死亡原因。私立大学是厄瓜多尔与卫生相关科研产出的领先者。
