A study on the influencing factors of social support on the quit smoking among community smokers in Beijing,China

Objective: To study the effect of social support on quit smoking, to provide theoretical reference and suggestions for the construction of social support for tobacco control. Methods Based on the design idea of case-control study, adult smokers who participated in the community smoking cessation intervention project in Beijing were selected as the study objects, and they were divided into successful quit smoking group and unsuccessful quit smoking group. The status of the public tobacco control policy, community tobacco exposure, and the environment of household tobacco control were compared between groups, and a structural equation modeling was established for ConfirmatoryFactorAnalysis. Results Our descriptive results showed that there were statistical differences in quit smoking results among smokers with different household tobacco control regulations, workplace tobacco control regulations and the number of smokers in the family, meanwhile there were differences in the 6-month smoking reduction with different levels of tobacco harm knowledge promotion and the interval between smoking behaviors at home. And the multivariate analysis indicated that household tobacco control regulations (OR = 1.302, 95%CI: 1.003 ~ 1.690), workplace tobacco control regulations (OR = 1.273, 95%CI: 1.052 ~ 1.540), the interval between smoking behaviors at home (OR = 1.145, 95%CI: 1.019 ~ 1.287) have statistical association with quit smoking. while the results of structural equation modeling found that public tobacco control policy (β = 0.388, P = 0.026) and the environment of household tobacco control (β = 0.368, P = 0.022) had statistical influence on quit smoking. Conclusion Public tobacco control policies and the environment of household tobacco control have substantial impact on the quit smoking. Specifically, household tobacco control regulations, workplace tobacco control regulations, tobacco harm knowledge publicity and the interval between smoking behaviors at home have a positive impact on the quit smoking effect of smokers, and the number of smokers in the family has a negative impact on the quit smoking.
