Overview

Background Sexual and gender minority populations experience elevated risks for suicidality. This study aimed to assess prevalence and disparities in non-fatal suicidality and potential protective factors related to social support and health care access among sexual and gender minority youth and adults and their heterosexual and cisgender counterparts in Canada. The second objective was to examine changes in the prevalence of suicidal ideation and protective factors during the COVID-19 pandemic. Methods Pooled data from the 2015, 2016 and 2019 Canadian Community Health Surveys were used to estimate pre-pandemic prevalence of suicidal ideation, plans and attempts, and protective factors. The study also estimated changes in the prevalence of recent suicidal ideation and protective factors in fall 2020, compared with the same period pre-pandemic. Results The prevalence of suicidality was higher among the sexual minority populations compared with the heterosexual population, and the prevalence was highest among the bisexual population, regardless of sex or age group. The pre-pandemic prevalence of recent suicidal ideation was 14.0% for the bisexual population, 5.2% for the gay/lesbian population, and 2.4% for the heterosexual population. The prevalence of lifetime suicide attempts was 16.6%, 8.6%, and 2.8% respectively. More than 40% of sexual minority populations aged 15–44 years had lifetime suicidal ideation; 64.3% and 36.5% of the gender minority population had lifetime suicidal ideation and suicide attempts. Sexual and gender minority populations had a lower prevalence of protective factors related to social support and health care access. The prevalence of recent suicidal ideation among sexual and gender minority populations increased in fall 2020, and they tended to experience longer wait times for immediate care needed. Conclusions Sexual and gender minority populations had a higher prevalence of suicidality and less social support and health care access compared to the heterosexual and cisgender populations. The pandemic was associated with increased suicidal ideation and limited access to care for these groups. Public health interventions that target modifiable protective factors may help decrease suicidality and reduce health disparities. Highlights • This study provides population-based pre-pandemic estimates of the prevalence of non-fatal suicidality (suicidal ideation, plans, and attempts) among sexual and gender minority populations in Canada using pooled data from the 2015, 2016, and 2019 Canadian Community Health Survey. • Sexual and gender minority populations had a higher prevalence of suicidal ideation, plans, and attempts, compared with heterosexual and cisgender populations, regardless of sex or age group. Among sexual minority populations the bisexual population had the highest prevalence of suicidality. • More than 40% of sexual minority populations aged 15 to 44 years had lifetime suicidal ideation; two thirds and one third of the gender minority population had lifetime suicidal ideation and suicide attempts, respectively. • Sexual minority populations had a lower prevalence of social support and health care access; the presence of social support and health care access was related to lower prevalence of recent suicidal ideation. • The onset of the COVID-19 pandemic was associated with increased recent suicidal ideation among the sexual and gender minority populations, especially for males, adolescents, and young adults.
