Cultural and demographic correlates of dual tobacco use in a sample of Alaska Native adults who smoke cigarettes

Abstract

INTRODUCTION Approximately 9 million American adults use two or more tobacco products regularly, referred to as dual or poly tobacco users. In Alaska, where tobacco is not native, approximately 20% of the population smokes cigarettes, and among smokers, 10% use two or more tobacco products. Previous research suggests that dual tobacco product use may be especially high among Alaska Native people. The current study examined cultural and demographic characteristics associated with dual tobacco use. METHODS Alaska Native adults reporting daily smoking and identified with high blood pressure or cholesterol were recruited in the Norton Sound region of Alaska between 2015-2019 as part of a treatment trial targeting cardiovascular disease risk factors. Participants reported their tribal group, level of identification with their Alaska Native heritage, speaking of their tribal language, basic demographic characteristics, and past 30-day use of tobacco products in addition to smoking cigarettes. RESULTS Participants (n=299) were 48.5% female and identified as Yup'ik (31.1%), Inupiat (60.5%), and other or multiple tribal group(s) (8.4%). Most participants (85.3%) strongly identified with their Alaska Native heritage. Past 30-day dual tobacco use was reported by 10.0%, specifically 9.0% chew/snuff, 1.3% e-cigarettes, and 0.7% Iq'mik. Multivariate regression models indicated that dual tobacco use was more likely among men (OR=3.35; 95% CI: 1.30-8.64), younger participants (OR range: 10.97-12.35; 95% CI: 2.33-57.86), those identifying as Yup'ik (OR=2.86; 95% CI: 1.13-7.19), and those who identified very little or not at all with their Alaska Native heritage (OR=2.98; 95% CI: 1.14-7.77). CONCLUSIONS Young men identifying as Yup'ik were more likely to use dual forms of tobacco. Stronger identification with one's Alaska Native heritage was associated with lower risk of dual tobacco use. The findings highlight cultural and demographic factors for further consideration and attention in tobacco cessation treatment interventions.

Impact of tobacco habits on poor oral health status among bone-factory workers in a low literacy city in India: A cross-sectional study

“…This issue should be addressed with a behavioral change awareness campaign for education among youth. Also, one in every ten bone-factory-worker consumes both forms of tobacco as dual tobacco users, which is similar to the findings reported by Epperson et al among youth [ 35 ]. A study reported that male dual tobacco users are at higher risk of gestational cancer and pregnant women for gestational hypertension [ 36 ].…”

Facebook Intervention to Connect Alaska Native People With Resources and Support to Quit Smoking: CAN Quit Pilot Randomized Controlled Trial

“…Prior interventions had limited reach to specific geographic locations in Alaska or AN populations. 41 , 42 The research validates the use of social media advertising to recruit AN people statewide into research studies. The intervention was well specified in a content library that was developed using a rigorous, iterative process.…”

Comparison between Smokers and Smokeless Tobacco Users in Their Past Attempts and Intentions to Quit: Analysis of Two Rounds of a National Survey

“…However, its achievement in reducing the overall prevalence of tobacco users through those control measures may be decelerated due to scarce cessation services and limited counselling facilities [ 31 , 32 ]. The treatment services that are available in Bangladesh focus mainly on smoking and rarely on SLT [ 33 ]. Cessation medications need to be made available and affordable [ 34 ].…”
