Educational disparities in the intention to quit smoking among male smokers in China: a cross-sectional survey on the explanations provided by the theory of planned behaviour

Objectives: We aim to describe the intention to quit smoking among Chinese male smokers from different educational backgrounds and to explain this intention from their attitude, perceived social norms and self-efficacy regarding smoking cessation. Setting: Participants were recruited from workplaces and communities to reflect the occupational distribution in three cities (Shanghai, Nanning and Mudanjiang) in China. Design: and participants In 2013 interviews were conducted with 3676 male smokers aged 18 years and older. Outcome: measures Multivariate logistic regression analyses calculated educational differences in the intention to quit smoking as well as the association between the intention to quit smoking and attitude, subjective norms, and self-efficacy. Bootstrapping estimated to what extent the educational disparities in the intention to quit smoking were mediated by these three determinants. Results No educational disparities in the intention to quit smoking within 1 or 6 months...

研究目的：本研究旨在描述不同教育背景的中国男性吸烟者的戒烟意愿，并从其戒烟态度、感知社会规范（perceived social norms）及戒烟自我效能感（self-efficacy）三个层面，阐释该戒烟意愿的形成机制。
研究场景：研究对象招募自工作场所与社区，以覆盖中国上海、南宁及牡丹江三座城市的职业分布特征。
研究设计与研究对象：2013年，本研究对3676名年满18周岁及以上的男性吸烟者开展了访谈调查。
结局指标：采用多因素logistic回归分析，计算戒烟意愿的教育差异，并分析戒烟意愿与态度、主观规范（subjective norms）及自我效能感之间的关联；通过Bootstrap自助法（Bootstrapping），估算上述三类决定因素对戒烟意愿的教育差异的中介效应程度。
