心理压力及疲劳对大学生不同吸烟行为的影响

目的研究心理压力及疲劳对大学生不同吸烟行为的影响。方法采用整群抽样法抽取某大学1～3年级在校大学生8138名，以自填式结构问卷调查学生的心理压力、自身和同伴吸烟情况及社会经济学指标，Chalder疲劳量表测量其躯体和精神疲劳。以“从未吸烟者”作为对照组，分别以“尝试吸烟者”和“现吸烟者”作为病例组，进行Multinomial logistic回归分析心理压力及疲劳对大学生不同吸烟行为的影响。结果进入大学后仍有学生尝试或形成吸烟行为。调整社会经济学指标和同伴吸烟行为的影响后，躯体疲劳（OR=1．044，95％CI：1．013～1．075）、对学业和未来工作的担心（OR=1．020，95％CI：1．001～1．040）是男生尝试吸烟的危险因素；学习压力（OR=1．063，95％CI：1．012～1．117）是女生尝试吸烟的危险因素；人际与环境压力（OR=1．152，95％CI：1．012～1．312）是女生现吸烟的危险因素。结论心理压力及疲劳和大学生吸烟行为存在一定程度的关联，且对不同性别和不同吸烟行为的影响是不同的。

Study on the impact of related psychological stress and fatigue to different smoking behaviOrs amongundergraduate students

OBJECTIVE: To explore the relationship between psychological stress, fatigue and different smoking behaviors among undergraduate students. METHODS: 8138 undergraduate students in grade 1 to 3 were sampled with cluster sampling method from a comprehensive university in Guangzhou, and were studied on their psychological stress, peer and self smoking behaviors, as well as socio-demographic factors with a self-administered questionnaire. Physical and mental fatigue was measured by Chalder fatigue scale. A multinomial logistic regression analysis was performed to explore the association between psychological stress, fatigue and different smoking behaviors with 'non-smokers' defined as control group while 'triers' and 'current smokers' as case group, respectively. RESULTS: There were students trying to smoke or becoming current smokers on university campus. After adjusting the effect of relevant socio-demographic factors and peer smoking behavior, physical fatigue (OR = 1.044, 95% CI: 1.013-1.075) and 'worry about current academic and future work' (OR = 1.020, 95% CI: 1.001-1.040) were the risk factors of trying to smoke among male students, while 'study stress (OR = 1.063,95% CI: 1.012-1.117) was the risk factor for female students when start smoking. 'Personnel relationship and environment stress' (OR = 1.152, 95% CI: 1.012-1.312) were the risk factors for female students' current smoking behavior. CONCLUSION: Psychological stress and fatigue were moderately associated with smoking behavior among undergraduate students and the impact was different on different gender and smoking behaviors that suggesting that some specific psychological measures should be taken so as to control different smoking behaviors among undergraduate students.
