Tobacco harm perceptions and use among sexual and gender minorities: findings from a national sample of young adults in the United States.

Introduction: In the United States, the prevalence of tobacco use among sexual and gender minorities (SGM) is higher compared to their non-SGM counterparts. Tobacco harm perceptions have gone largely unexamined as a potential mechanism supporting disproportionate tobacco use among this population. The purpose of this study was to examine differences between SGM and non-SGM young adults in harm perceptions of various tobacco products and tobacco use behavior and whether low tobacco-related harm perceptions moderate the relationship between identifying as a SGM and tobacco use behavior.

Methods: This study used data from Wave 10 of the Truth Initiative Young Adult Cohort Study, a sample of U.S. young adults (ages 18-34). Data were collected from September to October 2016 and the study sample included 3089 individuals. Demographics, past 30-day use of cigarettes, little cigars/cigarillos/bidis and electronic cigarettes were assessed. Absolute and relative harm perceptions of these products were also examined.

Results: Identifying as a SGM and low tobacco harm perceptions were found to be positively associated with past 30-day tobacco use. There was no interaction between SGM status and harm perceptions on past 30-day tobacco use CONCLUSIONS: Findings confirm that SGM young adults continue to disproportionately use tobacco products, compared to non-SGM young adults. More research is needed to understand moderators of the relationship between SGM status and tobacco use in young adults.
