Association between perceived harm of tobacco and intention to quit: a cross-sectional analysis of the Vietnam Global Adult Tobacco Survey

Abstract

Background Perception of harm plays an important role in predicting intention to quit—an integral part of the cessation process. Perception on harm from bamboo waterpipe tobacco was unknown, even the predominant of this type of tobacco use. This study investigated the effects of perceived harm from cigarette and bamboo waterpipe tobacco on intention to quit among adult male Vietnamese tobacco users. Methods From the nationally-representative 2015 Global Adult Tobacco Survey, we included 1,351 adult males (≥ 18 years old) who used cigarettes, bamboo waterpipes, or both. Demographic characteristics, tobacco use behaviors, perceived harm from tobacco use, and regulation/policy exposure were measured. Effects of perceived harm from cigarette and bamboo waterpipe tobacco on intention to quit were assessed by logistic regression. Results Intention to quit prevalence was 59.0%, 55.0%, and 58.4% for cigarette, waterpipe, and dual users, respectively. Tobacco users who perceived that “using cigarettes and/or waterpipe could cause severe illness” and “waterpipe use is less harmful than cigarette smoking”, had tobacco use bans at home, or were exposed to anti-smoking campaigns or encouragement to quit information were more likely to intend to quit. When analyzed by tobacco users, intention to quit was more likely for those users who perceived their tobacco product as more harmful than the other product type, although statistical significance was only observed for cigarette users. Conclusions Misperceptions regarding harm from tobacco use could negatively affect intention to quit. Dissemination of accurate information on the risks from all forms of tobacco use and enforcement of tobacco control policies are important for encouraging intention to quit.

Intention to Quit Tobacco due to Media Advertisements in India: Findings from Global Adult Tobacco Survey 2016-17

“…There were higher odds of having positive intentions to quit if the patient was aware of the harmful effects of tobacco. These results are similar to the estimates from another GATS country [23]. Perceived risk is important in predicting health behavior, as hypothesized per the Health Belief Model.…”

The influence of health literacy and knowledge about smoking hazards on the intention to quit smoking and its intensity: an empirical study based on the data of China’s health literacy investigation

“…For example, Stewart demonstrated significant associations between health literacy and nicotine dependence, smoking risk perceptions [ 26 ]. Furthermore, nicotine dependence and smoking risk perceptions have been identified as important influences on the intention to quit [ 27 , 28 ]. Therefore, it is reasonable to believe that health literacy may significantly influence the intention to quit smoking.…”
