This paper examines the mental health and substance use impacts of the COVID-19 pandemic among sexual and gender minority (SGM) populations as compared to non-SGM populations, and identifies risk factors for mental health and substance use impacts among SGM groups. Data were drawn from two rounds of a repeated cross-sectional monitoring survey of 6027 Canadian adults, with Round 1 conducted May 14-19, 2020 and Round 2 conducted September 14-21, 2020. Bivariate cross-tabulations with chi-square tests were utilized to identify differences in mental health and substance use outcomes between SGM and non-SGM groups. Separate multivariable logistic regression models were used to identify risk factors for mental health and substance use outcomes for all SGM respondents. Compared to non-SGM respondents, a greater proportion of SGM participants reported mental health and substance use impacts of the COVID-19 pandemic, including deterioration in mental health, poor coping, suicidal thoughts, self-harm, alcohol and cannabis use, and use of substances to cope. Among SGM respondents, various risk factors, including having a pre-existing mental health condition, were identified as associated with mental health and substance use impacts. These widening inequities demonstrate the need for tailored public mental health actions during and beyond the pandemic.

The negative mental health and substance use impacts associated with the COVID-19 pandemic have been widely documented and include increased stress, anxiety, depression and substance use (Salari et al., 2020; Twenge and Joiner, 2020; Xiong et al., 2020) . These impacts have been disproportionately experienced by key sub-populations ([Authors] , 2020), including sexual and gender minority (SGM) peoplethose who identify as lesbian, gay, bisexual, transgender, Two-Spirit, and queer (Brennan et al., 2020; Moore et al., 2021; Phillips et al., 2020) . The mental health consequences of COVID-19 on SGM people may amplify long-standing mental health inequities (Pakula et al., 2016; Plöderl and Tremblay, 2015) , including increased prevalence of depression (Borgogna et al., 2019; [Authors] , 2018), self-harm (King et al., 2008; Liu et al., 2019) , and suicide (Hottes et al., 2016; Mongelli et al., 2019; [Authors] , 2019). Further, SGM people experience higher rates of substance use in early life and adulthood (Boyd et al., 2020; Demant et al., 2016; Krueger et al., 2020) along with drug dependence and substance use disorders (Girouard et al., 2019; Mereish and Bradford, 2014) .

Mental health and substance use inequities among SGM people are driven by structural vulnerabilitiesrisk for negative health outcomes stemming from hierarchical power structures that create and maintain disparities in access to determinants of health (Bourgois et al., 2017) . For SGM populations, structural vulnerabilities that undermine opportunities for good mental health include discrimination in employment, housing, healthcare, and other aspects of daily life (Hatzenbuehler et al., 2013; Kattari et al., 2016; Valdiserri et al., 2019) , as well as barriers to community and family acceptance (Kibrik et al., 2019) . Together, Brooks (1981) and Meyer (2003) have conceptualized this spectrum of structural vulnerabilities impacting SGM people through the minority stress model. This model posits that SGMs experience distinct stressors of discrimination, violence, identity concealment, and internalized homophobia, which jeopardize mental health (Meyer, 2003) . This explanatory framework draws attention to the connections between discrete stressors and associated experiences of adverse mental health and substance use outcomes (Lee et al., 2016; McConnell et al., 2016; Mongelli et al., 2019; Rehman et al., 2020) .

The pre-existing mental health and substance use challenges experienced by SGM people are likely exacerbated by COVID-19 conditions, which emerging evidence is illustrating ([Authors, 2021] ; Moore et al., 2021) . SGM people are more likely to work in precarious, low-paying jobs and be susceptible to the economic impacts of the pandemic, such as cuts to work hours and job loss (Gibb et al., 2020; Goldberg, 2020) . In addition, physical distancing mandates and closures of businesses and gathering places have contributed to SGM communities experiencing a "sudden and significant loss" of safe spaces, including support groups and leisure and entertainment spaces, that facilitate individuals expressing their authentic selves and identities and building social connections (Anderson and Knee, 2020; Banerjee and Nair, 2020; Konnoth, 2020) . The 'shutting down' of these spaces and resultant loss of social support has led to many SGM individuals expressing lower connection to and pride in SGM communities, eroding important protective factors for mental health (Scroggs et al., 2020; Suen et al., 2020) . Public health restrictions, such as physical distancing and quarantine measures, have further led to SGM individuals' disconnection from supportive environments, resources, and social connections, resulting in negative mental health impacts, including lower levels of hope for the future and increased alcohol consumption (Scroggs et al., 2020) .

Literature prior to COVID-19 demonstrates disparities in mental health between SGM groups and non-SGM counterparts and recent literature within the pandemic context illustrates concerning mental health outcomes among SGM populations; however, there is limited research that directly compares SGM and non-SGM populations (Moore et al., 2021) . Yet, there is increasing concern that SGM populations may be overlooked in public policy and research responses to COVID-19 (Gorczynski and Fasoli, 2020; Salerno et al., 2020a) . To ensure that public policy and mental health resources and supports appropriately respond to the needs of SGM people, it is crucial to build an evidence base monitoring the relative mental health status of this priority population. Further, research reporting mental health experiences and outcomes among SGMs over time is critically important for informing the development of responsive policy and program interventions. Accordingly, the purpose of this paper is to compare SGM mental health and substance use impacts of the COVID-19 pandemic to non-SGM peers to identify risk factors for adverse mental health and substance use outcomes among SGMs. To do so, we draw on two rounds of data from a large repeated cross-sectional Canadian survey investigating the mental health impacts of the COVID-19 pandemic.

Data are drawn from a larger repeated cross-sectional monitoring survey, Assessing the Impacts of COVID-19 on Mental Health, which is being led through a collaboration between academic researchers from the University of British Columbia (UBC) and the Canadian Mental Health Association. The study additionally includes a partnership with the Mental Health Foundation in the United Kingdom. Our research team is strengthened by diversity in identities and lived experiences, and includes people who are queer and also who are living with mental health challenges. The full survey can be found in the supplementary material of [Authors] (2020).

Survey items were informed by a monitoring survey first commissioned by the Mental Health Foundation in March 2020. Original item development was guided by research evidence on mental health impacts of past pandemics. The survey was further refined through a citizens' jury participatory methodology process involving people with lived experience of mental health conditions (Mental Health Foundation, 2020) . Items were modified and questions added to reflect the Canadian context, and the survey was made available to participants in English and French.

Data are drawn from two survey rounds, with Round 1 conducted May 14-19, 2020 and Round 2 conducted September 14-21, 2020. Round 1 data collection occurred during what was a 'reopening' phase in many Canadian provinces following the initial identification of COVID-19 and approximately two months of associated restrictions (Vogel, 2020) . Round 2 data collection occurred at the end of the summer months, a period of relatively reduced virus transmission and greater easing of public health restrictions. It also marked the beginning of an upward trend in daily cases in Canada (John Hopkins Coronavirus Resource Center, 2021) .

For each round, the online anonymous survey was distributed by Maru/Matchbox, a national polling agency that maintains a panel of 125,000 individuals across Canada. Maru/Matchbox provides access to this panel for researchers, distributing the survey among a sample of panel members. Maru/Matchbox utilized randomly sampled from their panel of individuals 18 years or older living in Canada, according to Canadian census-informed socioeconomic stratifications of age, binary male/female strata, household income, and province to generate a nationally representative sample according to these characteristics. Response rates were 32% at Round 1 and 36% at Round 2. Survey participants provided online consent and were provided a small honorarium for completing the survey, according to Maru/Matchbox standard policies and procedures. Ethical approval was obtained from the Behavioural Research Ethics Board at UBC (H20-01273).

Socio-demographic characteristics were collected, including SGM identity, gender identity, age, household income, education, ethnicity, pre-existing mental health condition, rural/urban living environment, and household composition. In Round 1, gender was assessed by asking participants "Which gender do you most identify with?" with the following response options: "Man", "Woman", "Transgender woman/trans woman", "Transgender man/trans man", "Nonbinary", "Two-Spirit", "Not listed" and "Prefer not to answer". Based on feedback from members of the research team, this measure was updated to better reflect current best practices (Bauer et al., 2017) , and in Round 2, gender was assessed by asking participants which gender they most identify with followed by the options "Female", "Male", "Non-binary", "Two-Spirit", "Not listed" and "Prefer not to answer". Round 2 participants were also asked "What sex were you assigned at birth?" with the options "Male" and "Female". Transgender identities of Round 2 participants were then determined by comparing current gender identity with sex assignment at birth. Participants who responded yes or unsure to the question "Do you identify as being LGBT2Q+ (lesbian, gay, bisexual, trans, Two-Spirit, queer, etc.)?" were classified as SGM. To classify racialized persons within the sample, participants were asked to identify their "ethnic origin". Any participant who identified Indigenous family origin was classified as Indigenous, reflecting the Canadian context in which Indigenous peoples are considered a distinct subpopulation with unique experiences of health, well-being, and structural vulnerability compared to non-Indigenous racialized groups. Those who identified only European family origins were classified as being non-racialized, and those who identified one or more non-European origins were classified as being racialized. Having a pre-existing mental health condition as assessed through the question, "Do you identify as a person who has a pre-existing (prior to COVID-19) mental health condition?", with response options "Yes", "No", and "Prefer not to say".

Self-reported deterioration in mental health was assessed by asking "Compared to before the COVID-19 pandemic and related restrictions in Canada, how would you say your mental health is now?" with responses "Slightly worse now" and "Significantly worse now" classified as experiencing a "Deterioration in mental health". Responses "Significantly better now", "Slightly better now", and "About the same" were classified as not experiencing deterioration in mental health. Coping with stress was assessed by asking participants, "Overall, how well do you think you are coping with stress related to the COVID-19 pandemic?" with responses "Not very well" and "Not well at all" classified as "Poor coping" and responses "Very well" and "Fairly well" considered to not reflect "Poor coping". Experiencing suicidal thoughts and feelings and selfharm were assessed by asking participants, "Have you done or experienced any of the following as a result of the COVID-19 pandemic in the past 2 weeks?" with separate responses for "Experienced suicidal thoughts/feelings" and "Deliberately hurt myself." Participants were also asked to report impact of the COVID-19 pandemic on substance use, including alcohol and cannabis, with responses including "more", "less", "no change" and "not applicable"responses "less" and "no change" were combined into a single "no increase" category. An additional measure, "Has your use of substances increased as a way to cope at any point during the pandemic?" with responses "yes" and "no", was added in Round 2.

Descriptive statistics were used to characterize socio-demographics characteristics of the Round 1 and Round 2 samples with cross-tabulations included to compare SGM and non-SGM respondents on these characteristics. Bivariate cross-tabulations with chi-square tests were utilized to identify differences in mental health and substance use outcomes between SGM and non-SGM identity groups. Separate multivariable logistic regression models were then used to identify sociodemographic risk factors associated with the experience of each mental health and substance use outcome for all SGM respondents (Round 1 and 2 respondents combined) with round number included in the models as a covariate. The pooling of data from Rounds 1 and 2 was carried out to increase sample size for the SGM-specific analyses. If a respondent participated in both Round 1 and Round 2 surveys, then only their data from the Round 1 survey was retained in the pooled dataset for the regression analyses. This ensured that the survey rounds contained independent and non-overlapping samples. We further interpreted the associations within the pooled analyses as representing effects across the Spring-Fall 2020 time period (cumulative from the start of pandemic recall period to the time of second survey). Associations with p<0.05 were interpreted as statistically significant. All analyses were conducted using SPSS Version 27 (IBM Corp, 2020).

Sociodemographic characteristics of the Round 1 (n=2984) and Round 2 (n=3009) samples are provided in Table 1 . Considering both rounds together (N=6027), 7.5% of the sample identified as having SGM identity, 47.0% identified as male, and 18.2% of respondents reported having a pre-existing mental health condition.

The results of the bivariate cross-tabulations comparing SGM groups on mental health and substance outcomes for Round 1 and Round 2 samples are presented in Table 2 . A greater proportion of SGM participants reported impacts on their mental health and substance use across all outcomes for both rounds, as compared with non-SGM respondents.

A comparison of those who had versus had not completed multiple rounds on core socio-demographics (age, gender, household income, and reporting a pre-existing mental health condition) indicated significant differences in age with those aged 35 to 54 years slightly more likely to participate in multiple survey rounds compared to other age groups (Chi-square=6.209, p<.05).

The results of the multivariable logistic regression models identifying socio-demographic risk factors associated with the experience of each mental health outcome are presented in Table 3 . Several sociodemographic factors (e.g., being under 25 years of age, being Indigenous, and having a household income less than $25k) were associated with increased odds of reporting an adverse mental health impact, however, having a pre-existing mental health condition was more consistently associated with greater odds of experiencing an adverse mental health outcome (see Table 3 for details). Note: OR=odds ratio estimated by logistic regression, fully adjusted for all covariates shown. Variation across number of respondents included in the regression model for each mental health outcome varies due to some participants choosing not to answer some mental health outcome questions. Adults aged 35-54 years and 55 + years were combined into one group in the self-harm model to support model convergence. * p<0.05 ** p<0.01 a Non-binary and Two-Spirit respondents were excluded from the regression analyses due to low numbers and trans participants were included in their selfidentified gender category.

SGM: sexual and gender minority As shown in Table 4 , only two sociodemographic factors (household income and living in a rural setting) were associated with increased odds for specific substance use outcomes, while having a pre-existing mental health condition was more consistently associated with increased use of cannabis and increased use of substances to cope. Note: There is variation in the number of respondents included in the regression model for each substance use outcome, as some participants opted not to answer certain substance use questions (i.e., they selected "Not applicable" or "Prefer not to answer"). The alcohol and cannabis use outcome was dichotomized as "Increased use" and "No increase". Round was not included in the model examining use of substances to cope because this outcome was only included in the Round 2 survey. * p<0.05 ** p<0.01 a Non-binary and Two-Spirit respondents were excluded from the regression analyses due to low numbers and trans participants were included in their self-identified gender category. SGM: sexual and gender minority

This repeated cross-sectional monitoring survey drew on two rounds of Canadian national survey data and is among the first studies to examine the disparate mental health impacts of COVID-19 between SGM and non-SGM groups. Findings from this analysis indicate that SGM adults are significantly more likely than their non-SGM counterparts to experience wide-ranging mental health challenges amid the pandemic, including suicidal ideation, self-harm, poor coping, and using substances to cope. These findings are cause for immediate and ongoing public health attention, as they substantiate growing concerns that the COVID-19 pandemic will worsen mental health and substance use inequities experienced by SGM populations (Gorczynski and Fasoli, 2020; Salerno et al., 2020a) .

This analysis identified that across all measures, SGM adults were significantly more likely to experience adverse mental health outcomes in the context of COVID-19, relative to non-SGM adults. In particular, 23.4% of SGM adults surveyed reported suicidal thoughts at Round 2, and over half (52.8%) reported experiencing a deterioration in mental health. Within our study sample, the SGM sub-group differed significantly from the non-SGM group on pre-existing mental health conditions, household income, education, and other measures; these findings are expected, as they highlight the underlying structural inequities experienced by this population that perpetuate mental health inequities within the pandemic context (Gil et al., 2021; Lee et al., 2016) . Study findings extend emerging evidence demonstrating the adverse mental health impacts of COVID-19 among the general population ([Authors], 2020; Pierce et al., 2020) , and in identifying high prevalence of suicidal thoughts among SGM adults, contribute to the growing global concern that the pandemic may contribute to rising suicide attempts and deaths (Moser et al., 2020; Sher, 2020) . These findings further contribute to the literature by presenting empirical evidence of the inequitable mental health burden of COVID-19 for SGM populations, an observation which, at this juncture, has tended to be limited to projections and calls to action related to this population's mental health in the pandemic context (Gorczynski and Fasoli, 2020; Salerno et al., 2020b) . Hypothesized drivers of these mental health inequities include preexisting structural determinants (e.g., queerphobia, minority stress), as well as COVID-19specific factors, such as worsening unemployment and public health restrictions which constrain access to SGM community spaces and social supports (Gato et al., 2021; Jen et al., 2020; Phillips et al., 2020; Scroggs et al., 2020) . Given that community connection is a known protective factor for the mental health of SGM people (Formby, 2017; Meyer, 2015; Nogueira de Lira and Araujo de Morais, 2018) , innovative strategies are needed to preserve and promote this sense of community in the pandemic context, where access to many 'traditional' supports (e.g., community gatherings, Pride events, SGM recreational groups) is now restricted.

Our findings also indicate that many SGM adults are using substances to cope with the stress of the pandemic, at significantly higher rates than non-SGM adults. Research prior to the pandemic suggests that higher rates of substance use among SGM populations can be explained as "maladaptive" coping mechanisms in response to various stressors, including minority stress and mental health challenges (Hatzenbuehler et al., 2009; Morgan et al., 2020) . Predictably, the health and socio-economic impacts of COVID-19 are adding to this population's (and others') burden of stress; however, we are concerned for the continuation of these pronounced increases in substance use among SGM adults, particularly as a coping strategy for mental distress throughout the pandemic and its aftermath. Immediate research and policy attention is needed to redress existingand potentially wideningsubstance use inequities experienced by SGM adults, including patterns of use that may coincide with increased rates of drug dependence and substance use disorder (Czeisler et al., 2020; Lachowsky et al., 2017; Lee et al., 2016) .

This study further identified key risk factors for adverse mental health and substance use impacts of COVID-19 among SGM adults. Having a prior mental health condition(s) was strongly associated with experiencing mental health and substance use impacts, raising concerns that preexisting structural vulnerabilities impacting mental health among this population are being exacerbated within the pandemic context (Salerno et al., 2020b) . Having a lower household income was associated with increased odds of poor overall coping, corresponding to earlier research suggesting that SGM adults who are underemployed/unemployed and living in poverty may be particularly affected by the interrelated socio-economic and mental health consequences of COVID-19 (Gonzales et al., 2020) . Further, younger adults were more likely to experience suicidal thoughts aligning with research suggesting that younger SGM adults may have mental health challenges related to living in unsupportive households following shifts to online schooling and widespread unemployment (Salerno et al., 2020a (Salerno et al., , 2020c . Considering these exemplars, our findings highlight the need for continued research to delineate not only mental health disparities between SGM and non-SGM adults amid the pandemic, but also disparities within populations of SGM adults.

These analyses underscore that public health responses to the pandemic must take action to support the mental health of SGM (and non-SGM) adults. Given the interconnected nature of mental health and substance use outcomes identified in this study and elsewhere in our team's research ([Authors, 2021] ), we join others in calls for synergistic approaches to mental health and drug policy and practice with SGM adults (Czeisler et al., 2020; Lachowsky et al., 2017; Morgan et al., 2020) . Integral to COVID-19 approaches is the implementation and scale-up of online peer support groups and resources related to mental health and substance use, including those that foster mental health literacy, positive coping mechanisms, and/or harm reduction ([Authors], 2021; Liu et al., 2019; Zhou et al., 2020) . As we have previously argued, it is paramount that supports such as these be offered proactively, rather than reactively or "as needed" ([Authors], 2021; [Authors], 2020). Like others Salerno et al., 2020b) , we also appeal for these supports to be designed and implemented in ways that are safe and accessible (i.e., queer-friendly, gender-affirming) for SGM people, and responsive to this population's distinct needswhich may include, for example, the scale-up of SGM-exclusive and community-led supports. Also needed are structural policy interventions to address the root drivers of mental health inequities facing SGM populations (Morgan et al., 2020; Phillips et al., 2020) , including targeted educational supports to foster family and community acceptance of SGM people, anti-stigma and -violence efforts, and broader transformations in (cisheteronormative) societal laws and discourses related to SGM communities.

Although this comparative analysis offers important evidence for disproportionate mental health burdens of the pandemic for SGM adults, there are limitations to consider. Firstly, the use of a single item to capture SGM identity may lead to misclassification, particularly of individuals with same-sex/gender attraction who do not identify as "LGBT2Q+". However, a significant proportion of respondents (7.5%) identified as SGM, which is comparable to population estimates (Government of Canada, 2015). Additionally, while Two-Spirit and genderqueer respondents were included in descriptive results, logistic regression analyses necessitated a binary gender division, and we were unable to include these respondents in this model. Lastly, this study intentionally focused on self-reported experiences of mental health and substance use challenges; as such, survey measures did not include screening or clinical assessment tools, which limits some comparisons to other population data. Many items were adapted from previous surveys, though measures were not previously validated and psychometric analyses have not yet been conducted. Due to the nature of this study, participants were asked to selfreport changes in mental health from prior to the pandemic. While self-report research may be affected by recall bias, we considered six months an appropriate recall period for populationbased studies, given the widespread use of past-year measures.

This article identifies that while both SGM and non-SGM adult populations in Canada are selfreporting deteriorations in mental health amid the pandemic, SGM adults are facing mental health challenges at rates over and above those of their non-SGM peers. Evidence of this increase in mental health disparities is compelling, and important for transforming health-system responses to COVID-19 in ways that more fulsomely promote population-level mental health. Given the existing and widening inequities faced, decisive and tailored public mental health actions are needed to safeguard the mental health and well-being of SGM people over the remainder of the pandemic and beyond.
