Abstract Background Medical education often focuses on curative medicine, neglecting health determinants. Field visits, common in other educational contexts, enhance understanding of these factors. We aim to offer insights into pedagogical methods applicable to similar educational settings. Objectives Medical students completing an internship at the Gaia-Espinho Public Health Unit participated in field visits to enhance their understanding of health determinants. Guided through two economically distinct areas within a walkable distance of 2km, students documented health determinants through notes and photos. Discussions were held on-site and after visits integrating the real-world experience with theoretical frameworks. An inductive thematic analysis of students’ satisfaction and pedagogical effectiveness of the activity was performed on the internship reports from the 2023/2024 academic year. Results Out of 18 internship reports, 10 described the activity as positive and enriching, of which six highlighted it as a crucial part of the internship. Thirteen reports noted that the activity led to new perceptions about health determinants, and nine highlighted its practical value. Nine students included photos in their reports, bike paths being the most featured. Seventeen provided a clear description and listed the determinants they were able to detect. Discussions highlighted sensory experiences that are uniquely discernible through physical site visits including unpleasant odours, loud noises, and the cooling effect of blue areas on hot days. Three did not provide any evaluative comments, but correctly listed the determinants identified. Conclusions Field visits may enhance medical students’ understanding of health determinants, being recognized as an engaging pedagogical tool. Potential biases in assessments that rely on student satisfaction reports must be considered. Findings support the continuation and expansion of visits in other Public Health internships. Key messages • Field visits, used as a pedagogical tool, may enhance medical students’ ability to understand health determinants. • User Field visits provide a new perspective on previously acquired theoretical knowledge regarding prevention.
