目的了解深圳市光明新区中学生吸烟及其影响因素分布情况,为中学生吸烟干预措施的制定提供依据。方法运用分层整群抽样法对深圳市光明新区学校544名中学生进行吸烟状况、烟草有关知识、态度和行为、周围环境控烟情况等调查,使用SAS9.0软件分析。结果深圳市光明新区中学生尝试吸烟率为15.07%,男生(21.90%)显著高于女生(6.30%,P<0.05);中学生吸烟率为3.13%,男生(4.25%)和女生(1.68%)差异无统计学意义(P>0.05);高中生的尝试吸烟率和吸烟率分别为17.73%、1.42%,初中生的尝试吸烟率和吸烟率分别为14.14%、3.72%,初、高中学生其尝试吸烟率、吸烟率差异均无统计学意义(P>0.05)。82名尝试过吸烟的学生中,31.71%、24.39%的学生分别在7岁以前、12~13岁初始尝试吸烟;17名吸烟学生中,初始吸烟年龄主要集中在12~13岁(29.41%)、14~15岁(35.29%)和7岁前(23.53%)。93.01%、87.87%的学生分别知道吸烟和吸二手烟肯定危害健康,45.40%和52.21%的学生其父母与好朋友不吸烟。多因素非条件Logistic回归分析显示,女生比男生尝试吸烟可能性低(OR=0.50,95%CI:0.26~0.96),好朋友吸烟(OR=1.88,95%CI:1.08~3.27)、具有好朋友给烟肯定会愿意吸(OR=3.11,95%CI:2.12~4.54),年龄增加(OR=1.33,95%CI:1.04~1.69)增加了尝试吸烟的可能性。结论深圳市光明新区中学生吸烟现况不容乐观。加强同伴教育、提高中学生控烟主见等将有助于降低中学生的尝试吸烟率和吸烟率。
Objective To understand the distribution of smoking and its influencing factors among middle school students in Guangming New District, Shenzhen, and to provide the basis for the formulation of smoking interventions for middle school students. Methods A stratified cluster sampling method was used to investigate 544 middle school students in Guangming New District of Shenzhen City about smoking status, tobacco-related knowledge, attitude and behavior, and tobacco control in the surrounding area. SAS9.0 software was used to analyze the smoking status. Results The prevalence of smoking among middle school students in Shenzhen Guangming New District was 15.07%, male students (21.90%) were significantly higher than female students (6.30%, P <0.05), middle school students smoking rate was 3.13%, male students (4.25%) and female students The prevalence of smoking and smoking in high school students were 17.73% and 1.42%, respectively. The prevalence of smoking and smoking among junior high school students were 14.14% and 3.72%, respectively. There was no significant difference in smoking rate and smoking rate (P> 0.05). Of the 82 smokers who had tried smoking, 31.71% and 24.39% of students initially tried smoking before they were 7 years old and 12-13 years old respectively. Among the 17 smoking smokers, the initial smoking age was 12-13 years (29.41%), , 14 ~ 15 years old (35.29%) and 7 years old (23.53%). 93.01% and 87.87% of students knew that smoking and smoking secondhand smoke were definitely harmful to health, while 45.40% and 52.21% of students did not smoke their parents and good friends. Multivariate non-conditional logistic regression analysis showed that girls were less likely to attempt smoking than boys (OR = 0.50,95% CI: 0.26-0.96), good friends smoking (OR = 1.88,95% CI: 1.08-3.27) A friend of mine would definitely be willing to smoke (OR = 3.11, 95% CI: 2.12-4.54). Increasing age (OR = 1.33, 95% CI: 1.04-1.69) increased the likelihood of smoking. Conclusions Smoking prevalence in middle school students in Guangming New District of Shenzhen City is not optimistic. Reinforcing peer education and improving middle school students’ attitudes toward tobacco control will help reduce the prevailing smoking prevalence and smoking rates among middle school students.
