Protective Associations between Supportive Environment and Suicidality among Minority and Majority Adolescents

To examine the association between supportive environments and adolescent suicidal behavior, especially among marginalized minority groups.

Participants included 12,196 middle and 16,981 high school students who completed the 2019 Vermont Youth Risk Behavior Survey. Multiple logistic regression models were used to assess the association between three protective factors that were part of a supportive environment (feeling like they matter to people in their community, usually eating dinner at home, having a trusted adult) and suicidality (plan or attempt), controlling for key demographics (sex, sexual orientation, gender identity, and race/ethnicity). Moderating effects of demographics were also explored.

All supportive environment variables were protective of making a suicide plan and making a suicide attempt (ORs < 0.75, p-values < 0.005). Students of minority identities were significantly more likely to make a suicide plan (middle school ORs: 1.34-3.51, p-values < 0.0005; high school ORs: 1.19-3.38, p-values < 0.02) and attempt suicide (middle school ORs: 1.42-3.72, p-values < 0.006; high school ORs: 1.38-3.25, p-values < 0.0005) compared to students with majority demographic characteristics. Generally, the associations between having a supportive environment and suicidality did not vary within sexual orientation, gender identify, or race/ethnicity subgroups, suggesting that these supportive environment factors were more universally protective. However, a few associations were stronger among students in the majority demographic groups.

These data suggest that having a supportive environment is protective of suicidality for adolescents from both majority and minority demographic groups.
