Objective: Even the tobacco control law acts in 2010, the proportion of smoking in Vietnam remains high with one in two men smokes tobacco. The combination of tobacco non-taxes policies appears a crucial approach to reduce smoking prevalence. The objective of this study was to analyze the impact of population-level tobacco control interventions on smoking quit intention in Vietnam. Methods: Data was subtracted from a cross-sectional study among 900 current men smokers in Da Nang city, the third largest city in Vietnam. The target population comprised only adult men, 18 years of age or older, who had smoked more than 100 cigarettes in their lifetimes, smoked at least once in the past 30 days. Households were sampled using a stratified multistage design. Quit intention of smoking defines as they reported “in the next month”, “in the next 6 months” or “sometime in the future after 6 months”. Graphical warning labels on cigarette packs; mass media campaigns; and smoking bans (in public or in work places); advice from health professional was included as the main tobacco control intervention in Vietnam. Multivariate logistics model was used after adjustment other independent variables: knowledge, attitude, practice toward smoking; Heaviness of Smoking Index; demography. The analysis also stratified by age group (< 40 and >=40). Results: The proportion of smokers interested in quitting smoking was 30.26%. Among 4 intervention policies, mass media campaigns were significantly associated with an increase quit intention with odd ratio: 2.33 95%CI (1.29,4.23). In term of policy combination, two/more policies was significantly increased a quit intention with odd ratio 1.72 (1.11,2.65) in overall, whereas age group less than 40 years with OR: 1.93, 95%CI (1.05,3.55), respectively; but no significance for group more than 40 years with OR: 1.56 95%CI (0.82,2.97). Conclusions: The finding shows a positive effect of non-taxes policy approaches in increased a quit intention. A combination of these policies advances the quit intentions among cigarette smokers in Vietnam and presents its dose-response in this relationship, especially among young adult smokers.
