Predictors of Cessation in Men Using a Tobacco Quitline: A Follow-Up Study

Abstract

Although the effectiveness of tobacco quitline services for people who smoke cigarettes is well established, less is known about other forms of tobacco. This study aimed to compare quit rates and factors contributing to tobacco abstinence in men reporting dual use (smokeless tobacco and one additional combustible tobacco product), smokeless tobacco use only, and cigarette use only. Self-reported 30-day point-prevalence tobacco abstinence at the 7-month follow-up was calculated in males who registered with the Oklahoma Tobacco Helpline and completed a 7-month follow-up survey (N=3,721) (July 2015-November 2021). Logistic regression analysis completed in March 2023 identified variables associated with abstinence in each group. Abstinence was reported by 33% in the dual-use group, 46% in the smokeless-tobacco-use-only group, and 32% in the cigarette-use-only group. Eight or more weeks of nicotine replacement therapy provided by the Oklahoma Tobacco Helpline was associated with tobacco abstinence in men who reported dual use (AOR=2.7, 95% CI=1.2, 6.3) and exclusive smoking (AOR=1.6, 95% CI=1.1, 2.3). The use of all nicotine replacement therapy was associated with abstinence in men who used smokeless tobacco (AOR=2.1, 95% CI=1.4, 3.1) and who smoked (AOR=1.9, 95% CI=1.6, 2.3). The number of helpline calls was associated with abstinence in men who used smokeless tobacco (AOR=4.3, 95% CI=2.5, 7.3). Men in all three tobacco-use groups who fully utilized quitline services showed a greater likelihood of tobacco abstinence. These findings underscore the importance of quitline intervention as an evidence-based strategy for people who use multiple forms of tobacco.
