This study evaluated the impact of the tax increase in January 2019 on changes in intention to quit and the effect of cigarette prices on quit attempts and successful quitting among male cigarette smokers in Vietnam.
Data were derived from the ITC project in Vietnam, which included 1585 adult smokers at baseline (Wave 1, Aug-Oct 2018) followed up to waves 2 (Sep-Nov 2019) and 3 (Sep-Dec 2020). Generalized estimating equations regression was performed to estimate changes in the intention to quit. Multiple logistic regression analysis was used to evaluate the cigarette price of a cigarette pack in relation to quit attempts and successful quitting.
The increase in cigarette tax in 2019 did not significantly increase the likelihood of the intention to quit. After the tax increase, 63.6% of participants who smoked made a quit attempt, and 27.6% successfully quit smoking in the follow-up waves. However, the price of a cigarette pack was not significantly associated with quit attempts and successful quitting. The study did not observe a significant impact of cigarette prices on quit attempts and successful quitting in all subgroups of household income. Factors associated with quit attempts included the number of cigarettes smoked and the intention to quit, while those associated with successful quitting included age, dual use of cigarettes and other tobacco products, and the intention to quit.
Current cigarette prices were not associated with cessation behaviors even within the lowest household income group. Therefore, a sharp rise in cigarette tax is required to incentivize smokers to quit smoking.
本研究评估了 2019 年 1 月增税对越南男性吸烟者戒烟意愿变化的影响，以及香烟价格对戒烟尝试和成功戒烟的影响。
数据来自越南 ITC 项目，该项目包括 1585 名成年吸烟者，在基线（第 1 波，2018 年 8 月至 10 月）进行随访，直至第 2 波（2019 年 9 月至 11 月）和第 3 波（2020 年 9 月至 12 月）。使用广义估计方程回归估计戒烟意愿的变化。使用多因素逻辑回归分析评估一包香烟的价格与戒烟尝试和成功戒烟的关系。
2019 年香烟税的增加并没有显著增加戒烟的可能性。增税之后，63.6%的吸烟者尝试戒烟，在后续随访中，27.6%的吸烟者成功戒烟。然而，香烟价格与戒烟尝试和成功戒烟没有显著关联。研究在所有家庭收入亚组中都没有观察到香烟价格对戒烟尝试和成功戒烟的显著影响。与戒烟尝试相关的因素包括吸烟数量和戒烟意愿，而与成功戒烟相关的因素包括年龄、同时使用香烟和其他烟草制品，以及戒烟意愿。
即使在家庭收入最低的群体中，当前的香烟价格也与戒烟行为无关。因此，需要大幅提高香烟税来激励吸烟者戒烟。
