Research Trends on Diabetic Foot in Latin America: A Bibliometric Analysis (2000-2025).

Abstract

AimsDiabetes-related foot disease (DFD) is a prevalent and costly complication of diabetes in Latin America (LATAM). Our bibliometric study aims to identify emerging research output from LATAM countries, knowledge gaps, and future opportunities in research.MethodsA bibliometric analysis between 2000 and 2025 was done using PubMed and Scopus databases. English-language articles with corresponding authors affiliated with LATAM institutions were included. A total of 1423 records were screened, with 435 meeting inclusion criteria. Data on authorship, country, study type, citations, journal impact, and collaboration type were extracted and analyzed.ResultsOverall, Brazil contributed to 51.5% publications, followed by Mexico (18.6%) and Cuba (7.8%). Citation analysis revealed a total of 9397 citations, with a median of seven citations per publication. Venezuela and Barbados had the highest median citations per article, despite low output. Collaboration analyses showed that only 1.6% involved intra-LATAM collaborations. International collaborations outside the region were associated with higher median citations. Observational studies (n = 198) were most prevalent, with experimental, trial, and review studies showing significant growth over time.ConclusionDespite the recent growth of DFD research in Latin America, structural barriers such as research equity, international visibility, and regional collaboration persist. Addressing these by strengthening intra-regional collaboration, improving funding equity, and investing in research infrastructure may enhance scientific visibility and improve healthcare outcomes for DFD in the region.
