To analyze the scientific production of primary care research in Latin American and Caribbean (LAC) countries from 1980 to 2024 and to provide recommendations for improvement.
Observational, machine learning-based bibliometric study.
Review and research articles indexed in the Web of Science database.
Bibliometric analysis was performed on data from 33 LAC countries, retrieved from the Web of Science as of April 15, 2024.
For each record, data on the journal, year of publication, article title, abstract, keywords, authors, affiliations, countries, cited sources, cited first authors, and references were extracted for bibliometric and text mining analyses. We used a form of machine learning, Latent Dirichlet Allocation topic modeling, to identify the key topics of research.
LAC countries contributed only 0.83% of the global literature on primary health care, with just 0.98% of this output comprising research and review articles. The majority of research originated from Brazil, Mexico, Colombia, and Chile, while many LAC countries produced little to no output. LAC countries frequently collaborated with the United States, Spain, Canada, and England. Research topics in the region predominantly focused on cancer, obesity, COVID-19, nutritional disorders, and food safety within the primary health care field.
The findings highlight significant potential for growth in primary health care research in LAC countries. Strengthening individual and collective strategies to build research capacity and fostering collaborations with global academic networks are recommended to enhance research output and impact.
分析1980年至2024年拉丁美洲和加勒比地区（LAC）国家初级保健研究的科研产出，并提出改进建议。
基于机器学习的观察性文献计量研究。
科学引文索引数据库中收录的综述和研究文章。
对截至2024年4月15日从科学引文索引中检索到的33个LAC国家的数据进行文献计量分析。
对于每条记录，提取有关期刊、出版年份、文章标题、摘要、关键词、作者、所属机构、国家、被引文献、被引第一作者和参考文献的数据，用于文献计量和文本挖掘分析。我们使用一种机器学习形式，即潜在狄利克雷分配主题建模，来确定研究的关键主题。
LAC国家在全球初级卫生保健文献中仅占0.83%，其中只有0.98%的产出为研究和综述文章。大部分研究来自巴西、墨西哥、哥伦比亚和智利，而许多LAC国家的产出很少或几乎没有产出。LAC国家经常与美国、西班牙、加拿大和英国合作。该地区的研究主题主要集中在初级卫生保健领域的癌症、肥胖、COVID-19、营养失调和食品安全方面。
研究结果突出了LAC国家初级卫生保健研究的巨大增长潜力。建议加强个人和集体战略以建设研究能力，并促进与全球学术网络的合作，以提高研究产出和影响力。
