Social Smoking and Mental Health Among Chinese Male College Students.

PURPOSE: China has a high prevalence of smoking, but the characteristics of social smoking in Chinese college students have not been investigated. We examined the pattern of social smoking and explored the association between social smoking and personal cessation efforts and mental health factors among Chinese male college students.

DESIGN: Study design was a cross-sectional survey.

SETTING: P. R. China was the setting of the study.

SUBJECTS: Participants were a random sample of 1327 male college students.

MEASURES: All participants completed a self-administered questionnaire that examined their smoking behaviors and a group of specific mental health factors (loneliness, self-harm, suicide, depression, and anxiety).

ANALYSIS: Analysis was conducted using descriptive statistics, χ(2) analysis, and multivariate logistic regression.

RESULTS: Of a total of 207 current smokers, 102 (49.3%) were identified as social smokers. Compared with nonsmokers, social smokers had increased risks for depression (odds ratio, 1.74; 95% confidence interval, 1.15-2.65). Among daily smokers, social smokers were less likely to have an intention to quit smoking than nonsocial smokers (odds ratio, .08; 95% confidence interval, .01-.57).

CONCLUSION: This study reveals unique psychologic characteristics related to social smoking. College students are a particular group of interest because unhealthy behaviors initiated during adolescence may continue through adulthood. Our findings provide evidence for future tobacco control intervention among this population.
