A research team examined responses from a baseline survey of 304 African American adolescent women. They assessed psychosocial factors such as perceived racial discrimination and depression and analyzed participants' saliva samples for genotyping

Research conducted by Jessica Sales, associate professor in the department of Behavioral Sciences and Health Education at Emory's Rollins School of Public Health, examined the extent to which genetic variation — differences within a particular region of a gene (5-HTTLPR) that processes emotions — links to perceived racial discrimination and high levels of depressive symptoms in African American adolescent women.

Sales and her research team examined responses from a baseline survey of 304 African American adolescent women. They assessed psychosocial factors such as perceived racial discrimination and depression and analyzed participants' saliva samples for genotyping.

The team found that an interaction between perceived racial discrimination and 5-HTTLPR was significantly associated with depressive symptoms.

"A growing body of research suggests that perceived racial discrimination is especially harmful to the mental health of African American youth," said Sales. "Several cross-sectional studies have demonstrated that perceptions of racial discrimination are associated with lower self-esteem, increased anger, and increased anxiety and depressive symptoms among African American adolescents. 

"Our findings show that there is a great need to develop interventions that address racial discrimination," Sales continued. "Whether it's addressing coping mechanisms, support system outreach or other methods for emotional regulations, these interventions are the first step in protecting our youth from the psychological effects of discrimination."

Sales will present her complete findings at a poster session scheduled for 6 p.m. CT on April 23 during the Society of Behavioral Medicine's 2015 Annual Meeting & Scientific Sessions in San Antonio. Sales is a society member.
