Mental Health and Substance Use Disparities by Sexual Orientation and Gender Identity Among Delaware Youth.

Objective: To investigate mental health and substance use disparities by sexual orientation and gender identity among Delaware youth. Methods: Data were from the Delaware School Surveys (DSS) administered to 8th and 11th graders ( Results: Around one in four (25-26%) Delaware youth identified as LGBT+, including 6-7% of youth who were transgender or nonbinary. Rates of lifetime mental health symptoms and underage substance use were elevated among LGBT+ youth for every health outcome. For 8th grade LGBT+ youth relative to cisgender heterosexual youth, odds were elevated by 269% for psychological distress, 276% for anxiety, 91% for drinking, 141% for cigarette smoking, 121% for vaping, 98% for marijuana use, and 86% for prescription drug misuse. In 11th grade LGBT+ youth relative to cisgender heterosexual youth, odds were elevated by 228% for psychological distress, 240% for anxiety, 33% for drinking, 71% for cigarette smoking, 51% for vaping, 57% for marijuana use, and 70% for prescription drug misuse. Conclusions: Mental health and substance use disparities between LGBT+ youth and cisgender heterosexual youth highlight an alarming public health crisis in Delaware. With growing numbers of youth identifying as LGBT+ and persistent health disparities, state policy and clinical practice must be attuned to the needs and lived experiences of LGBT+ youth to identify and eliminate drivers of these disparities. Schools, healthcare, and policy provide important avenues for intervention.
