 This study assessed the differences in behavioral health between cisgender heterosexual adolescents and those who identify as lesbian, gay, bisexual, transgender, queer and questioning, and a sexual LGBTQA+, in Thailand. The results showed that LGBTQA+, adolescents are more likely to have higher rates of depression, suicidal thoughts, and alcohol consumption compared to cisgender heterosexuals. Additionally, LGBTQA+, adolescents reported higher rates of sexual behaviors, illicit drug use, and past year experiences of violence compared to cisgender heterosexuals. These findings suggest that there may be disparities in behavioral health between these two populations, which could potentially lead to increased risk of negative health outcomes among LGBTQA+, adolescents.
