Factors Influencing the Gender Breakdown of Academic Radiology Residency Programs

Abstract Purpose To determine the gender distribution of radiology residency programs and identify associations with radiology departmental factors. Methods The residency programs affiliated with the top 50 research medical school from US News and World Report were identified. The gender of all radiology residency graduates from each program from 2011 to 2015 were collected. Radiology departmental factors were collected: gender of chairperson, gender of program director, gender of faculty, geographic location, and city population of the residency program. The median percentage of female radiology faculty and residents were calculated and classified as above or below the median. Comparisons were made between residency programs and departmental factors via a Pearson χ2 univariate test or logistic regression. Results There were 618 (27.9%) female and 1,598 (72.1%) male residents in our study, with a median female representation of 26.4% in each program. Programs with a female residency program director were significantly more likely to have an above-median percentage of female residents versus a male program director (68.4% versus 38.7%, P = .04). Programs in the Northeast (70.6%) and West (70.0%) had higher above-median female representation than the South (10.0%) and Midwest (38.5%, P < .01). There was no association with city population size ( P = .40), gender of faculty ( P = .40), residency size ( P = .91), or faculty size ( P = .15). Conclusion Radiology residency programs with a female residency program director and those in the Northeast or West have a greater concentration of female residents. Residency programs that aim to increase female representation should investigate modifiable factors that can improve their recruitment practices.
