Culturally Tailored Anti-Smoking Messages: A Randomized Trial With U.S. Sexual Minority Young Women

INTRODUCTION:This study evaluated effects of exposure to culturally tailored anti-smoking ads versus control ads on quitting intentions, cigarette purchase intentions, and tobacco industry perceptions among young adult, cisgender and transgender, sexual minority women (SMW). STUDY DESIGN:An online randomized controlled experiment with 1-month longitudinal follow-up was conducted. SETTING AND PARTICIPANTS:About 2,214 U.S. SMW ages 18-30 were recruited via online survey panels (The PRIDE Study and Prolific), social media ads and posts, and HER dating app ads. Data were collected in 2021-2022. INTERVENTION:Participants were randomly assigned to receive up to 20 tailored ads containing LGBTQ+ branding versus 20 control ads without LGBTQ+ branding over 4 weeks. Both conditions used identical anti-smoking statements and photographs (including several photographs of individuals who self-identified as SMW). MAIN OUTCOME MEASURES:One-month follow-up intention to purchase cigarettes, intention to quit, marketing receptivity, pro-industry attitudes, and pro-industry beliefs were measured. Analyses were conducted in 2022-2023. Linear regression models predicted outcomes at 1-month follow-up with the randomized arm, adjusted for baseline measures of each outcome and stratified by smoking status (those who currently smoked and those who did not smoke). RESULTS:Among those who smoked, follow-up intention to quit increased and intention to purchase cigarettes, marketing receptivity, pro-industry attitudes, and pro-industry beliefs decreased versus baseline in both arms. Follow-up pro-industry beliefs were significantly lower (B=-0.331, 95% CI -0.652, -0.010, p=0.043) in the tailored versus control arm, adjusted for baseline beliefs. Among those who did not smoke, marketing receptivity, pro-industry attitudes, and pro-industry beliefs decreased versus baseline in both arms. Follow-up outcomes did not differ significantly between arms. CONCLUSIONS:These findings can inform future anti-smoking campaign development to reduce cigarette smoking-related disparities among young adult, cisgender and transgender, sexual minority women and serve as the basis for developing similar ads for other LGBTQ+ audiences. TRIAL REGISTRATION:This study was registered in ClinicalTrials.gov (NCT04812795).
