ABSTRACT

Objective@#To investigate the status and identify the influencing factors of smoking behaviors among residents in Nanshan District, Shenzhen City, so as to provide insights into tobacco control. @*Methods@#Permanent residents at ages of more than 18 years were recruited from 17 communities in Nanshan District, Shenzhen City using the stratified multistage random sampling method from July to November, 2018. Participants' demographic features, smoking, smoking cessation and exposure to secondhand smoke were collected using the Individual Questionnaire for 2018 Chinese Adult Chronic Disease and Nutrition Surveillance. The factors affecting current smoking were identified using a multivariable logistic regression model.@*Results@#Totally 1 700 questionnaires were allocated, and 1 625 valid questionnaires were recovered, with an effective recovery rate of 95.59%. The respondents included 714 men and 911 women, with a male to female ratio of 1∶1.27, and had a mean age of ( 45.13±13.59 ) years. The prevalence of current smoking was 15.51%, with 28.15% prevalence in men and 5.60% in women. The mean age of starting daily smoke was ( 21.00±5.52 ) years, and the mean daily smoking frequency was (13.53±9.15) cigarettes/d. The prevalence of smoking cessation was 6.58%, with 10.64% in men and 3.40% in women, and the prevalence of exposure to secondhand smoke was 41.42%, including 46.63% in men and 37.32% in women. Multivariable logistic regression analysis showed that an educational level of junior high school ( OR=1.683, 95%CI 1.088-2.602 ), an educational level of high school/technical secondary school/vocational school (OR=1.687, 95%CI 1.185-2.402), an occupation of farmers ( OR=2.514, 95%CI 1.404-4.500 ), and an occupation of commercial and service personnel ( OR=1.939, 95%CI 1.093-3.439 ) were associated with current smoking.@*Conclusion@# The prevalence of current smoking is low among residents in Nanshan District, but the prevalence of current smoking in women is higher than the national level.
