Impact of medical students’ socioeconomic backgrounds on medical school application, admission and migration in Japan: a web-based survey

OBJECTIVES: The aim of this study was to clarify and compare the socioeconomic backgrounds of medical students with those of other health professions and non-health faculty students in an era of increasing inequity in Japanese society. DESIGN: This was a quantitative nationwide study. Data were collected by a cross-sectional web-based anonymous questionnaire. SETTING: Data from years 3 and 4 medical, health professions and non-health faculty students across Japan were collected in 2021. PARTICIPANTS: Participants were 1991 students from medical schools, 224 from dental, 419 from pharmacy, 326 from nursing, 144 from other health professions and 207 from non-health faculties. RESULTS: The proportion of high-income families (>18 million yen: ca. US$140 000) among medical students was 25.6%, higher than that of pharmacy (8.7%) and nursing students (4.1%) (p<0.01). One-third of medical students had a physician parent, more common than in non-medical students (p<0.01). Students who only applied to public medical schools and a regional quota ‘Chiiki-waku’ students with scholarship had lower family income and physician parents compared with those who applied to private medical schools (p<0.01), but they still had higher physician parents compared with non-medical students (p<0.01). Logistic regression revealed that having a physician parent (p<0.01), aspiring to the present profession during elementary school (p<0.01) and private upper secondary school graduation (p<0.01) predicted the likelihood of studying medicine. There were regional differences of backgrounds among medical students, and 80% of medical students with urban backgrounds intended to work in urban localities after graduation. CONCLUSIONS: This study provides evidence that medical students in Japan hail from urban and higher income classes and physicians’ families. This finding has implications for the health workforce maldistribution in Japan. Widening the diversity of medical students is essential for solving physician workforce issues and meeting broad healthcare needs.
