Epidemiology in the Journal Ciência & Saúde Coletiva: analysis of the year 2024

Abstract This article aimed to analyze the Epidemiology scientific production in the Journal Ciência & Saúde Coletiva in 2024, updating a previously published article that examined publications from 1996-2002, 2011, and 2019. The selection was based on a review of the title and abstract (and, in some cases, the methods) of the original research articles and systematic reviews. One hundred twenty-five (40.1%) of the 305 articles whose title was considered were classified as epidemiological studies. Regarding the thematic classification, the three most common were “Evaluation of health systems, policies, programs, and services” (16%), “Epidemiology of accidents, violence, and physical injuries” (13.6%), and “Epidemiology of adolescent health” (9.6%). Approximately 56% were descriptive/cross-sectional studies, 24.2% focused on the adult population, 47.4% were conducted in the universe of subjects, 46.4% had more than 5,000 participants, and 40.8% were from authors from the Southeast. The results point to notable changes compared to the previous article, with a decrease in descriptive/cross-sectional studies and an increase in time series trends and sample sizes, possibly explained by the strengthening of serial population-based surveys and the use of information from Brazilian information systems.
