Many countries are employing strategies intended to reduce maldistribution of health workers and inequities. The purpose of this study was to analyse the impact of expansion policies of medical schools on regional inequalities in the distribution of undergraduate class sizes, and the capacity to attract and retain doctors and to expand health facilities.We conducted a descriptive analysis to compare the distribution of undergraduate places in 2007 and 2016 to determine the impact of targeted expansion policies on inequalities in access to medical education in Brazil. A group of municipalities with new medical schools (n = 54) and a control group without medical schools (n = 408) were compared to analyse impacts of expansion in the health sector. We compared the increase in the number of physicians per 1000 inhabitants and health establishments per inhabitants between 2007 and 2016 based on these two groups. We also analysed the relationship between geographic distance from the state capital and capacity to attract physicians.There was a decrease in the regional inequalities of undergraduate places in medical schools; the greatest increase in the places per 1000 inhabitants was in municipalities of between 50 000 and 100 000 inhabitants. Municipalities with new medical schools showed an increase in physicians per 1000 inhabitants and in health establishments per inhabitant ratio, demonstrating the potential to attract and retain doctors, as well as strengthening the health infrastructure. Municipalities more distant from state capitals showed a greater increase in physician : inhabitant ratio.Countries with health workforce shortages and inequalities in their distribution might consider public financing and regulation policies for expansion of medical schools as a strategy to attract and retain professionals. Early results in Brazil showed that such strategies could strengthen service networks in deprived areas, supporting implementation of Universal Healthcare Coverage.
