Global Research Trends on Hypertension among Young Adults: Bibliometric Analysis and Visualizations of Literature from 2015 to 2024

Hypertension is the most common cardiovascular disease, affecting an estimated 1.28 billion adults worldwide, with a rapidly increasing burden among young adults driven largely by modifiable behavioral risk factors. Although substantial research exists, few bibliometric studies have systematically examined the global research landscape and evolving priorities in young adult hypertension. This bibliometric analysis examined 4,609 English-language articles published between 2015 and 2024 and indexed in the Scopus database. Trends in publication output, authorship, institutional and country contributions, collaboration networks, and research themes were analyzed using bibliometric mapping methods. The findings show a steady increase in publications and citations over the study period, with the United States leading in research output and international collaboration. Harvard Medical School and the University of Birmingham emerged as key institutional contributors. Thematic analysis shows that shift in research focus from pathophysiology, complications, and treatment outcomes in earlier years toward risk-based prevention, lifestyle factors, psychosocial determinants, digital health, and machine learning approaches in more recent years. Overall, the results indicate both the maturation of research on hypertension among young adults and persistent gaps, particularly in intervention-based and longitudinal studies, highlighting the need for interdisciplinary and context-specific approaches to support early prevention and precision management.
