Smoke-free policies (SFPs) in public places are increasing globally, but developing countries are lagging behind. Understanding youth attitudes towards SFPs can inform SFP initiatives.
A multilevel logistic regression analysis of data collected from youth aged 13-15 years (2000-2006) who completed the Global Youth Tobacco Survey (GYTS) in 115 countries, primarily in the developing world, was conducted. The analysis examined relationships between support for SFPs and individual-level measures related to smoking status, and exposure to secondhand smoke (SHS), controlling for demographic and environmental factors of interest and country-level policy factors.
In all, 77.3% of 356,395 youth in 115 countries favoured SFPs, including majorities of non-smokers (78.7%) and smokers (63.6%). In the multivariable analysis knowledge of smoke harm was the strongest predictor of favouring SFPs (OR 2.42, 95% CI 2.27 to 2.67). Exposure to countermarketing (OR 1.40, 95% CI 1.25 to 1.57) and school anti-smoking education (OR 1.22, 95% CI 1.13 to 1.31) were also positively associated. Current smoking (OR 0.48, 95% CI 0.41 to 0.53), susceptibility to smoking (OR 0.46, 95% CI 0.40 to 0.52) and exposure to tobacco promotion were negatively associated. Significant country-level variation was observed. The presence of any national smoke-free legislation in a country was positively associated with youth favouring such policies.
The majority of youth worldwide support, yet lack, smoke-free policies in public places, while being regularly exposed to SHS. Youth support of SFPs is most positively associated with knowledge of the harmful effects of tobacco smoke. Redoubling education efforts represents an opportunity to establish smoke-free environments and improve health of children in developing countries.
在全球范围内，公共场所的无烟政策（SFPs）正在增加，但发展中国家却落后了。了解年轻人对 SFPs 的态度可以为 SFP 计划提供信息。
对来自 115 个国家/地区 13-15 岁（2000-2006 年）的青少年进行了多水平逻辑回归分析，这些青少年完成了全球青少年烟草调查（GYTS），主要在发展中国家进行。该分析考察了支持 SFPs 与与吸烟状况和二手烟（SHS）暴露相关的个体水平措施之间的关系，同时控制了感兴趣的人口统计学和环境因素以及国家政策因素。
在所有 115 个国家/地区中，共有 77.3%的 356,395 名青少年支持 SFPs，其中包括非吸烟者（78.7%）和吸烟者（63.6%）的大多数。在多变量分析中，对烟雾危害的认识是支持 SFPs 的最强预测因素（OR 2.42，95%CI 2.27-2.67）。接触反营销（OR 1.40，95%CI 1.25-1.57）和学校反吸烟教育（OR 1.22，95%CI 1.13-1.31）也呈正相关。当前吸烟（OR 0.48，95%CI 0.41-0.53）、易吸烟（OR 0.46，95%CI 0.40-0.52）和接触烟草促销呈负相关。观察到显著的国家层面差异。一个国家存在任何国家无烟立法都与青少年支持此类政策呈正相关。
世界上大多数年轻人都支持公共场所的无烟政策，但缺乏这种政策，同时经常接触二手烟。青少年对 SFPs 的支持与对烟草烟雾有害影响的认识最为密切相关。加倍教育努力是建立无烟环境和改善发展中国家儿童健康的机会。
