Following Barack Obama's reelection as U.S. president in 2012, the mental health of college-educated Black men improved significantly, while those who didn't attend college reported worse mental health, according to new research from Rice University sociologists.

"Four More Years! Or So What? The Mental Health Significance of Barack Obama's 2012 Presidential Re-Election among Black Adults" is published in the Du Bois Review: Social Science Research on Race.

Lead researcher Tony Brown, distinguished professor of sociology at Rice, said he and his co-authors were interested in following up their study examining the health implications of Obama's election in 2008—which showed positive mental health effects for Black males—and seeing what, if anything, changed.

Brown and his co-authors examined black adults' mental health for 30 days prior to and 30 days following the 2012 election. Data for the study came from the Behavioral Risk Factor Surveillance System, a nationally representative survey of 400,000 U.S. adults evaluating different health aspects.

Similar to their study results following Obama's 2008 election, the researchers found the 2012 reelection resulted in a significant mental health shift for Black men. However, this time around, not all men saw health benefits.
