Objective  To explore the intention and determinants of smoking cessation among preschoolers' caregivers in Changsha, and to provide scientific evidence for taking effective intervention measures to reduce children's exposure to secondhand smoke.

Method  The study was conducted between August and October 2013. A multistage cluster random sampling design was used to select kindergartens from three districts and one county in Changsha, and 425 smoking caregivers were enrolled.

Result  The proportion of the male participants with intention to quit smoking was 4.5%. The smoking caregivers with master's degree and above had the highest proportion of smoking cessation intention (12.9%), followed by those with college education or bachelor's degree (6.0%) and high school or technical secondary school education (0.7%). The results of multivariate analysis suggested that child's morning cough after getting up (OR=3.840, 95%CI: 1.361-10.834), child's health condition in past three months (OR=16.958, 95%CI: 41.466-196.189), and child's objection to smoker's smoking in front of him/her (OR=5.766, 95%CI: 1.740-19.169) influenced the intention of smoking cessation.

Conclusion  The willingness to quit smoking among preschoolers' caregivers in Changsha is very low, which is influenced by education, household income, knowledge of passive smoking, child's objection to passive smoking, and health condition of children.
