Tobacco Control Act of 2010 mandates government to implement at least 75% pictorial health warnings (PHWs) on tobacco packaging that was enforced in 2013. The purpose of the study was to assess the effectiveness of PHWs and its impact to the policy change.
A cross-sectional study was conducted in 9 cities between September 2014 and March 2015. Direct interviews were made among 2250 randomly selected individuals. The effectiveness of PHWs were measured as perceived: i) scariness; ii) quit motivation iii) convincing youth not to start smoking; iv) encouraging ex-smokers to remain as quitters; v) building public awareness. Logistic regression analysis was used to determine the factors associated with the effectiveness of PHWs.
Of the 2250 participants, 29.8% (670) were current smokers, 8.6% (193) were ex-smokers and 97.6% believed that smoking was addictive. PHWs made 83% of the participants scared. Participants believed that PHWs would be effective in motivating smokers to quit (80.2%), in convincing youth not to start smoking (86.8%), in encouraging ex-smokers to remain as quitters (89.1%) and in building public awareness on the dangers of smoking (94%). PHWs made 58% of the current smokers intended to quit smoking and reduced their daily intake of cigarettes from 11 to 5 on average. Current smokers preferred to purchase loose cigarettes rather than a pack. The covariates significantly associated with the effectiveness of PHWs were current smokers, ex-smokers and addiction.
PHWs were found important to motivate smokers to quit smoking, to reduce consumption of cigarettes and to prevent relapse in ex-smokers. Evidence from the study had triggered policy changes which included enlargement of the size of PHW to 90% and the release of a notification to ban selling of loose cigarettes. Thus, the warning messages with pictures are required to be improved and rotated.
2010 年的《烟草控制法案》要求政府在烟草包装上实施至少 75%的图片健康警示(PHW),该规定于 2013 年生效。本研究的目的是评估 PHW 的效果及其对政策变化的影响。
本研究于 2014 年 9 月至 2015 年 3 月在 9 个城市进行了一项横断面研究。通过随机选择的 2250 名个体进行直接访谈。通过以下方式衡量 PHW 的效果:i)令人恐惧;ii)戒烟动机;iii)劝阻年轻人不要开始吸烟;iv)鼓励戒烟者继续戒烟;v)提高公众意识。采用逻辑回归分析确定与 PHW 效果相关的因素。
在 2250 名参与者中,29.8%(670 名)为当前吸烟者,8.6%(193 名)为戒烟者,97.6%的参与者认为吸烟具有成瘾性。PHW 使 83%的参与者感到恐惧。参与者认为 PHW 将有效促使吸烟者戒烟(80.2%)、劝阻年轻人不要开始吸烟(86.8%)、鼓励戒烟者继续戒烟(89.1%)以及提高公众对吸烟危害的认识(94%)。PHW 使 58%的当前吸烟者有意戒烟,并平均将每天的吸烟量从 11 支减少到 5 支。当前吸烟者更愿意购买散装香烟而不是一包香烟。与 PHW 效果显著相关的协变量为当前吸烟者、戒烟者和成瘾性。
PHW 对促使吸烟者戒烟、减少香烟消费和防止戒烟者复吸非常重要。研究结果引发了政策变化,包括将 PHW 的尺寸扩大到 90%和发布通知禁止销售散装香烟。因此,需要改进和轮换警示图片的健康警示信息。
