Researchers have found that attempted suicide rates and suicidal ideation among lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQQ) youth is comparatively higher than among the general population. LGBT teens and young adults have one of the highest rates of suicide attempts. According to some groups, this is linked to heterocentric cultures and institutionalised homophobia in some cases, including the use of rights and protections for LGBT people as a political wedge issue like in the contemporary efforts to halt legalising same-sex marriages.Depression and drug use among LGBT people have both been shown to increase significantly after new laws that discriminate against gay people are passed.
Research on completed suicides in sexual minorities is preliminary. Members of the LGBT community have higher rates of all-cause mortality, and those living in areas with a higher degree of social stigma towards homosexuality tend to complete suicide at a younger age.
Bullying of LGBT youth has been shown to be a contributing factor in many suicides, even if not all of the attacks have been specifically addressing sexuality or gender. Since a series of suicides in the early 2000s, more attention has been focused on the issues and underlying causes in an effort to reduce suicides among LGBTQ youth. The Family Acceptance Project's research has demonstrated that "parental acceptance, and even neutrality, with regard to a child's sexual orientation" can bring down the attempted suicide rate. Suicidal ideation and attempts seem to be roughly the same for heterosexual youth as for youth counterparts who have same-sex attractions and behavior but do not identify as being LGBTQ. This correlates with the findings of a large survey of US adults that found higher rates of "mood and anxiety disorders, key risk factors for suicidal behavior", are linked to people who identify as gay, lesbian, and bisexual, rather than sexual behaviors, especially for men.
