Objectives We aim to describe the intention to quit smoking among Chinese males from different educational backgrounds and to explain this intention from their attitude, perceived social norm, 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 3,676 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 norm, 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 one or six months were observed among male Chinese smokers (p=0.623 and p=0.153 respectively). A less negative attitude, a higher perceived subjective norm towards smoking cessation, and a higher perceived self-efficacy to quit smoking were all associated with more smokers wanting to quit (all p-values <0.001).
Perceived subjective norm was the only component of the Theory of Planned Behaviour that statistically significantly mediated the differences in the intention to quit smoking (within one or six months) between the lowest educated Chinese men and the lower (β=0.039, 95%CI 0.017-0.071 and β=0.043, 95%CI 0.019-0.073), higher (β=0.041, 95%CI 0.017-0.075 and β=0.045, 95%CI 0.019-0.077) and highest educated groups (β=0.045, 95%CI 0.019-0.080 and β=0.050, 95%CI 0.023-0.083).
Conclusions In order to prevent future socioeconomic disparities in smoking cessation, investment in a more stimulating social environment and norm towards smoking cessation among particularly the lowest educated Chinese men is warranted.
