Measuring cigarette and e-cigarette use over time among LGBT+ youth and young adults using a repeat cross-sectional survey, 2022-2024.

Introduction: LGBT+ individuals in the U.S. use tobacco products more than their heterosexual and cisgender peers. Although existing literature identifies this trend, more research using recent, national data from a large sample is needed to better examine trends over time.

Methods: A repeat cross-sectional survey of approximately n=300 youth and young adults aged 15-24 was fielded weekly from October of 2022 to June of 2024, resulting in a total sample of N=25,675. This sample was used to examine cigarette and e-cigarette use over time among LGBT+ and non-LGBT+ youth and young adults. Cigarette and e-cigarette use was also examined by specific sexual orientation and gender identity, using the aggregated sample.

Results: From October 2022 - June 2024, cigarette and e-cigarette use were consistently higher among LGBT+ youth and young adults, compared to their cisgender and heterosexual peers. Compared to heterosexual young people, gay/lesbian and bisexual young people reported higher cigarette and e-cigarette use. Male-identifying individuals reported the highest cigarette use while, female young people reported the highest e-cigarette use. Transgender and gender diverse individuals reported lower cigarette and e-cigarette use than cisgender young people.

Conclusions: Tobacco use disparities persist among LGBT+ youth and young adults. Sexual minority respondents showed elevated risk of tobacco use, while gender minority youth saw lower rates of tobacco use, although prevalence remains high. Future research should continue to investigate LGBT+ tobacco use using national surveillance methods. Effective programs for tobacco prevention and cessation are necessary to advance health equity among LGBT+ youth and young adults.

Implications: This study finds persistently elevated tobacco use among LGBT+ youth and young adults over a two-year period, highlighting the importance of continued tobacco use surveillance, as well as the development of programmatic interventions to reduce LGBT+ tobacco use. These analyses also inform future work further investigating differences in tobacco use by sexual orientation and gender identity among young people. This work provides a call to action to focus efforts on reducing tobacco use among LGBT+ youth, improving the long-term health of this population and increasing health equity.
