Objective  To examine previous attempt and current plan of smoking cessation and their influencing factors among voluntary smoking quitters in Gansu province for providing evidences to develop effective intervention on smoking cessation.

  Methods  From January 2015 through August 2016 in Gansu province, we carried out a telephone survey among 420 voluntary smoking quitters over 18 years old and above who called 12320 health hotline for smoking related consultation. The participants′ information on previous attempt and current plan of smoking cessation and their related factors were collected with a self-designed questionnaire and analyzed statistically.

  Results  Of all the participants, 198 (47.14%) reported attempting to quit smoking during past one year and 152 (36.19%) reported the intention to quit smoking in the next month. The results of unconditional multivariate logistic regression analysis demonstrated that the participants with indoor smoking at home being prohibited absolutely were more likely to have smoking cessation attempt during past one year (odds ratio OR = 3.501, 95% confidence interval 95% CI: 1.868 – 6.561) compared to those without the prohibition; the results also indicated that the participants with following characteristics were more likely to have smoking cessation plan: at younger age (≤ 40 years vs. > 40 years: OR = 1.887, 95% CI: 1.068 – 3.335), indoor smoking at home being prohibited absolutely (yes vs. no: OR = 3.553, 95% CI: 1.695 – 7.444), with a higher number of cigarettes smoked per day (> 10 vs. ≤ 10: OR = 3.300, 95% CI: 1.902 – 5.726), and having smoking cessation attempt during past one year (yes vs. no: OR = 8.986, 95% CI: 5.376 – 15.021).

  Conclusion  No smoking at home is a main influencing factor of previous attempt and future plan of smoking cessation among voluntary smoking quitters in Gansu province. Improving 12320 health hotline service, establishing family support network for smoking cessation, and strictly implementing no smoking in public places may effectively promote smoking cessation among smokers.
