Smoking-related knowledge, attitudes, and behaviours among Alaska Native people: a population-based study

Abstract

BackgroundSeveral studies have shown that Alaska Native people have higher smoking prevalence than non-Natives. However, no population-based studies have explored whether smoking-related knowledge, attitudes, and behaviours also differ among Alaska Native people and non-Natives.ObjectiveWe compared current smoking prevalence and smoking-related knowledge, attitudes, and behaviour of Alaska Native adults living in the state of Alaska with non-Natives.MethodsWe used Alaska Behavioral Risk Factor Surveillance System data for 1996 to 2010 to compare smoking prevalence, consumption, and cessation- and second-hand smoke-related knowledge, attitudes, and behaviours among self-identified Alaska Native people and non-Natives.ResultsCurrent smoking prevalence was 41% (95% CI: 37.9%–44.4%) among Alaska Native people compared with 17.1% (95% CI: 15.9%–18.4%) among non-Natives. Among current every day smokers, Alaska Natives were much more likely to smoke less than 10 cigarettes per day (OR=5.0, 95% CI: 2.6–9.6) than non-Natives. Compared with non-Native smokers, Alaska Native smokers were as likely to have made a past year quit attempt (OR=1.4, 95% CI: 0.9–2.1), but the attempt was less likely to be successful (OR=0.5, 95% CI: 0.2–0.9). Among current smokers, Alaska Natives were more likely to believe second-hand smoke (SHS) was very harmful (OR=4.5, 95% CI: 2.8–7.2), to believe that smoking should not be allowed in indoor work areas (OR=1.9, 95% CI: 1.1–3.1) or in restaurants (OR=4.2, 95% CI: 2.5–6.9), to have a home smoking ban (OR=2.5, 95% CI: 1.6–3.9), and to have no home exposure to SHS in the past 30 days (OR=2.3, 95% CI: 1.5–3.6) than non-Natives.ConclusionAlthough a disparity in current smoking exists, Alaska Native people have smoking-related knowledge, attitudes, and behaviours that are encouraging for reducing the burden of smoking in this population. Programs should support efforts to promote cessation, prevent relapse, and establish smoke-free environments.
