Depression and suicide attempts in LGB people: evidence graded convincing

Design

Umbrella review of 22 meta-analyses of observational studies, with credibility grading

Population

LGBTQIA+ populations compared with cisgender heterosexual populations, 398 studies

Primary outcome

Mental disorders, symptoms, suicidal behaviour and access to care

Effect

Depressive disorders RR 2.05 (1.69–2.48); suicide attempts RR 2.51 (2.14–2.94)

An umbrella review in World Psychiatry pulled together 22 meta-analyses, covering 398 observational studies and 162 associations, on mental health in LGBTQIA+ populations. Each association was graded by standard credibility criteria. Eight reached the top grade.

Compared with heterosexual people, lesbian, gay and bisexual people had about twice the risk of depressive disorders and about two and a half times the risk of suicide attempts. Combined suicidal ideation or attempts showed an odds ratio of about 3.2. Gay adolescents had higher odds of dieting and purging than heterosexual peers. Within the group, bisexual people had higher odds of anxiety symptoms and non-suicidal self-injury than lesbian and gay people.

These are associations from observational data and do not by themselves explain why; the authors point to stigma and discrimination. But the evidence is strong enough that sexual orientation belongs among the factors a clinician considers when assessing mood and suicide risk — asked about sensitively, with privacy assured, and recorded only with consent. In India, where disclosure may carry family and social risk, confidentiality is part of the clinical answer, not an afterthought.

• Include sexual orientation and gender identity, asked sensitively and privately, in assessments of low mood and suicide risk.
• Screen LGB patients presenting with depression specifically for suicidal thoughts and past attempts.
• Ask about self-injury in bisexual patients, in whom the odds were higher than in lesbian and gay peers.
• Check for restrictive eating and purging in gay adolescent boys, who are easily missed by screening built around girls.
• Make clear what will and will not be recorded or shared before asking.

Why it matters

A risk factor graded as convincing is still routinely left out of risk assessments because clinicians do not ask.

Don't overread it

These are observational associations; they identify higher-risk groups but do not show what causes the difference.

The statistics, in plain English

A risk ratio of 2.51 for suicide attempts means about two and a half times the risk. The confidence interval (2.14 to 2.94) is narrow and well clear of 1.0, which is part of why it was graded convincing — the estimate is precise and consistent across many studies.
