Follow-up survey of Japanese medical students’ interactions with the pharmaceutical industry

Interaction of medical students with the pharmaceutical industry is common. However, students are thought to be vulnerable to the influence of this interaction, and regulations to limit such interactions are required. The Japan Pharmaceutical Manufacturers Association revised its promotion code in 2013 and specified upper limits for promotional aids. We aimed to investigate whether Japanese medical students’ interactions with the pharmaceutical industry changed from 2012 to 2016. This study solicited the participation of all medical schools in Japan. An anonymous cross-sectional survey was administered to medical students from May 2016 to March 2017 to investigate their interactions with the pharmaceutical industry. The results were compared with those of a previous study conducted in 2012. Forty of the 80 medical schools in Japan participated. The student response rate was 74.1%, with 6771 (3395 preclinical, 3376 clinical) evaluable responses. More than 98% of clinical students had previously accepted stationery, a brochure, or a lunch, and significantly higher percentages of clinical students had accepted these items in 2016 than in 2012 (p < .001). The interactions between clinical students and pharmaceutical companies increased slightly between 2012 and 2016. This study will hopefully promote discussion regarding the regulation of student–industry interactions.
