Purpose/Objective(s): Workforce composition in radiation oncology has been increasingly characterized in high-income countries; however, national data from middle-income settings remain limited. We evaluated gender distribution across training level, academic cohort, and geographic mobility among radiation oncology residents in Mexico.
Materials/Methods: This multicenter cross-sectional study included all actively enrolled radiation oncology residents (PGY1–PGY4) from six national training programs in Mexico between 2022 and 2025. Institutional academic records were reviewed, constituting a complete census without exclusions or missing data. Gender (male/female) was recorded as self-identified in official records. Geographic mobility was defined as residency enrollment in a state different from the resident’s documented state of origin. Descriptive statistics characterized gender distribution. Group comparisons used chi-square or Fisher’s exact tests (p < 0.05) in SPSS.
Results: Ninety-three residents were included. Overall gender distribution was balanced (49.5% women; 50.5% men). Variability was observed across the training pipeline: women represented 71.4% of PGY2 residents, whereas other levels demonstrated a more balanced distribution (38.5%–45.8% women). Across academic cohorts, the proportion of women ranged from 38.5% to 71.4%, with one cohort showing female predominance. Women were slightly more represented among residents training outside their state of origin (54.2% vs 45.8%). No statistically significant differences in gender distribution were identified across training level, academic year, mobility status, or training site.
Conclusion: Radiation oncology training in Mexico demonstrates overall gender balance with cohort-level variability but no significant structural disparities. As the first nationwide census of gender representation in Mexican radiation oncology residency programs, this study establishes a national benchmark to inform longitudinal monitoring and workforce planning in middle-income health systems.
