Medical students who previously attended community colleges are more likely to serve poor communities, according to a recent study.

Researchers from UCLA, UC San Francisco and San Jose City College found that, among students who apply to and attend medical school, those from underrepresented "minority" backgrounds are more likely than white and Asian students to have attended a community college at some point. Community college students who were accepted to medical school were also more likely than those students who never attended a community college to commit to working with underserved populations.

For the study, researchers collected and analyzed data from the 2012 Association of American Medical Colleges matriculant and applicant files and the AAMC's Matriculating Student Questionnaire. They examined the association between students' participation in a community college pathway, medical school admission and intention to practice medicine in underserved communities.

Researchers found that a higher proportion of underrepresented minority matriculants used the community college pathways compared with white students or other racial and ethnic groups. Thirty-four percent of Latinos had attended community colleges, (538 of 1,566 matriculants), compared with 28 percent of black students (311 of 1,109), 27 percent of white students (2,715 of 9,905), 27 percent of Asian students (963 of 3,628) and 30 percent of students identifying themselves as mixed-race or other race (393 of 1,310).

They also found that applicants who attended community college after high school before transferring to a four-year college or university were 30 percent less likely to be admitted, compared to those students who never attended a community college or only attended a four-year university to medical school, after adjusting for age, gender, race and ethnicity, parental education, grade point average and MCAT score. The same group also was 26 percent more likely to intend to practice medicine in an underserved area than their non-community college educated peers.

The findings were published online by Academic Medicine.
