Description of samples.

This study examined differences in alcohol use by sexual and gender identities during the COVID-19 pandemic, and assessed whether variation between groups was explained by pandemic-related stressors and minority stress. Data from 2,429 partnered adults in the National Couples’ Health and Time Use Study (n = 3,593) collected from September 2020 to April 2021 were used to model drinking patterns (frequency, amount, and drinking to cope) by sexual and gender identities, COVID-19 stress and disruption, microaggressions, and supportive climate. Regression models indicated differences in drinking by gender and sexual identities, even controlling for demographic and socioeconomic factors. Gay, lesbian, and bisexual people had higher odds of drinking to cope with the pandemic than did heterosexual people, and cisgender men had higher odds than did cisgender women. Gay and lesbian people drank more regularly than did heterosexual people, as did cisgender men in relation to cisgender women. Exclusively bisexual people drank significantly more drinks than exclusively heterosexual people, and cisgender men drank significantly more drinks than did cisgender women and those who identified as trans/another gender identity. COVID-19 stress and minority stress were associated with greater alcohol consumption, but they did not account for these differentials. Moving forward, researchers will need to continuously assess these associations, as sources of discrimination and stress will persist beyond the pandemic. Although LGBTQ+ people have disproportionate sources of stress, they varied in how they used alcohol to cope. Potential sources of resilience among sexual and gender diverse individuals should be explored.
