Trajectories of Depressive Symptoms and Suicidality Among Heterosexual and Sexual Minority Youth

Although studies have shown that sexual minority youth (adolescents who report a same-sex romantic or sexual orientation) report higher rates of depression and suicidality than do heterosexual youth, it was unclear whether these disparities continue as youth transition into young adulthood.   A 2011 report from the Institute of Medicine found three key areas of importance when investigating health disparities among sexual minority individuals:  1) further investigation of mental health disparities within the sexual minority community is needed; 2) such research must take into account the entire life progression to observe longstanding patterns; and 3) underlying causes to these mental health issues can be explained with the minority stress model, which attributes the health problems in sexual minority individuals to the stress resulting from consistent pattern of bias and prejudice present in a predominantly heterosexual culture. The report’s findings inspired a study by Dr. Michael Marshal, Sarah Dermody and their colleagues to more fully investigate mental health trends among sexual minority individuals during the transition from youth to young adulthood. 

Utilizing data from the National Longitudinal Study of Adolescent Health, Dr. Marshal and his team analyzed rates of depression and suicidality for heterosexual youth and sexual minority youth.  They determined that not only were depression and suicidal rates higher for sexual minority youth than for heterosexual youth, but the differences between these two groups continued from adolescence into young adulthood.  The greatest gaps in these rates were seen for females and for individuals who identified as bisexual.  The investigators concluded that prevention efforts and early intervention programs beginning in childhood and early adolescence are needed to address these higher rates of depression and suicidality in sexual minority youth.
