目的探讨学习成绩与现在吸烟的可能关联。方法采用调查问卷,调查辽宁省25 710名12~23岁学生。结果现在吸烟率,男生为26.8%,女生为5.7%,男女合计为15.5%。差、较差、中等、较好、好5个学习成绩水平之间,男生的现在吸烟率分别为32.0%、25.6%、25.0%、14.6%、17.4%,差异有统计学意义(χ2=209.341,P=0.000);女生分别为9.0%、6.6%、4.3%、3.4%、2.7%,差异也有统计学意义(χ2=90.274,P=0.000)。重点高中、普通高中、职业高中3类高中之间,男生的现在吸烟率分别为15.0%、22.7%、44.4%,差异有统计学意义(χ2=425.904,P=0.000),女生分别为3.9%、4.2%、9.7%,差异有统计学意义(χ2=80.564,P=0.000)。结论学生现在吸烟率与“绝对”的学习成绩(学校类型)、“相对”的学习成绩(班级排位)都有着密切关联。学习成绩差的学生、职业高中学生明显高,应为重点干预人群。
Objective To explore the possible correlation between academic achievement and current smoking. Methods A questionnaire was used to survey 25 710 students aged 12 to 23 in Liaoning Province. Results Smoking prevalence rates were 26.8% for boys and 5.7% for girls and 15.5% for men and women. The prevalence of smoking in boys was 32.0%, 25.6%, 25.0%, 14.6% and 17.4%, respectively, with a statistically significant difference (χ2 = 209.341 , P = 0.000). The differences were also statistically significant (χ2 = 90.274, P = 0.000) for girls with 9.0%, 6.6%, 4.3%, 3.4% and 2.7% respectively. The prevalence of smoking in boys and girls is 15.0%, 22.7% and 44.4% respectively among the three key high schools, senior high schools, senior middle schools and vocational high schools. The prevalence of smoking in boys and girls is statistically significant (χ2 = 425.904, P = 0.000) , 4.2% and 9.7% respectively, with significant difference (χ2 = 80.564, P = 0.000). Conclusions Students’ current smoking rates are closely related to the academic performance of “Absolute” (school type) and “Relative” (class rank). Students with poor academic performance, occupation high school students were significantly higher, should focus on intervention groups.
