Transgender and non-binary people (TGNB) have a higher rate of heavy episodic drinking than cisgender people; however, extant knowledge about predictors of hazardous alcohol drinking (HAD) among different TGNB groups is limited. This study examined predictors of HAD in a national sample of TGNB people in Canada.
Logistic regression models were fit to examine the effects of 1) minority stressors and 2) stress-buffering factors on the likelihood of HAD, stratified by gender, among 2324 TGNB individuals from the Trans PULSE Canada survey, a cross-sectional survey conducted in 2019 among trans and non-binary people aged 14+ in Canada.
Almost 17% of participants reported past-year HAD. Lifetime day-to-day and lifetime major discrimination were associated with higher odds of HAD in the full sample [(AOR=1.37, 95% CI: 1.30, 1.44) and (AOR=1.69, 95% CI: 1.55, 1.86) respectively], and across all gender groups. Social support was associated with lower odds of HAD in trans men, non-binary people assigned female at birth (NB-AFAB), and non-binary people assigned male at birth (NB-AMAB) groups, but with higher odds of HAD in the trans women group. Misgendering was associated with lower odds of HAD in trans men and NB-AFAB, but higher odds of HAD in trans women and NB-AMAB. Mixed effects of gender distress, gender positivity, and gender-affirming medical care were also reported across groups.
The study provided a more detailed understanding of the predictors of HAD across four TGNB groups. Public health interventions should focus on structural discrimination and social support for TGNB people.
跨性别和非二元性别者（TGNB）比顺性别者有更高的重度间歇性饮酒率；然而，关于不同 TGNB 群体中危险饮酒（HAD）的预测因素的现有知识有限。本研究在加拿大的 TGNB 人群的全国样本中检验了 HAD 的预测因素。
逻辑回归模型用于检验 1）少数群体压力源和 2）压力缓冲因素对 2019 年在加拿大进行的跨性别和非二元性别者的横断面调查 Trans PULSE Canada 调查中，2324 名 TGNB 个体中 HAD 的可能性的影响，按性别分层。
近 17%的参与者报告过去一年有 HAD。终生日常和终生重大歧视与全样本中 HAD 的更高可能性相关 [(AOR=1.37, 95% CI: 1.30, 1.44) 和 (AOR=1.69, 95% CI: 1.55, 1.86)]，以及所有性别群体。社会支持与跨性别男性、出生时被指定为女性的非二元性别者（NB-AFAB）和出生时被指定为男性的非二元性别者（NB-AMAB）群体中 HAD 的可能性降低相关，但与跨性别女性群体中 HAD 的可能性增加相关。错性别与跨性别男性和 NB-AFAB 中 HAD 的可能性降低相关，但与跨性别女性和 NB-AMAB 中 HAD 的可能性增加相关。跨性别焦虑、性别积极和性别肯定性医疗护理的混合效应也在各群体中得到了报道。
该研究提供了对四个 TGNB 群体中 HAD 预测因素的更详细的了解。公共卫生干预措施应侧重于针对 TGNB 人群的结构性歧视和社会支持。
