16~18岁青少年体育锻炼与吸烟行为的关系

  目的  探讨16~18岁青少年体育锻炼与吸烟行为的关系，为促进青少年控烟提供参考。  方法  以2018年中国家庭追踪调查(CFPS 2018)中的1 057名青少年为调查对象，调查其吸烟与体育锻炼情况，采用χ2检验、Mann-Whitney U检验、Pearson相关分析、Logistic回归分析探讨青少年体育锻炼与吸烟行为的关系。  结果  被试青少年中有104(9.8%)名吸烟者，开始吸烟的年龄为(14.21±2.68)岁，戒烟年龄为(14.41±2.72)岁。年龄(χ2=7.23)、性别(χ2=83.01)、上学状态(χ2=107.12)、体育锻炼(Z=-2.20)、主观幸福感(Z=-2.20)和生活满意度(Z=-2.93)是青少年吸烟风险的相关因素(P值均 < 0.05)。体育锻炼与青少年吸烟行为呈负相关(OR=0.92，P=0.03)，控制人口统计学和社会认知心理变量后，负相关作用无统计学意义(OR=0.93，P=0.08)；进一步分析显示，体育锻炼与男生吸烟呈负相关(OR=0.91，P=0.04)，但与女生吸烟可能性的关系无统计学意义(OR=1.12，P=0.20)。  结论  体育锻炼与16~18岁青少年吸烟风险呈负相关，但未发现体育锻炼与女生吸烟行为的关联，有待后续研究进一步探讨。

Relationship between physical exercise and smoking behavior of adolescents aged 16-18

  Objective  To explore the relationship between physical exercise and smoking behavior in adolescents aged 16-18, and to provide reference for promoting tobacco control among teenagers.  Methods  A total of 1 057 adolescents who took part in the 2018 China Family Panel Studies (CFPS 2018) were investigated for smoking and physical exercise. The Chi-square test, Mann-Whitney U test, Pearson correlation analysis and Logistic regression analysis were performed to explore the relationship between adolescent physical exercise and smoking behavior.  Results  There were 104 (9.8%) smokers among the adolescents. The age at starting smoking was (14.21±2.68) years old and the age of quitting smoking was (14.41±2.72) years old. Age (χ2=7.23), gender (χ2=83.01), school status (χ2=107.12), physical exercise (Z=-2.20), subjective well-being (Z=-2.20) and life satisfaction (Z=-2.93) were associated with adolescent smoking(P < 0.05). Physical exercise was negatively correlated with adolescent smoking (OR=0.92, P=0.03). After controlling demographic and psychosocial and cognitive variables, the negative correlation was not statistically significant (OR=0.93, P=0.08). Further analysis showed that physical exercise was negatively correlated with boys smoking (OR=0.91, P=0.04), but it was not statistically correlated with girls smoking (OR=1.12, P=0.20).  Conclusion  Physical exercise is associated with lower rate of smoking among adolescents aged 16-18, but no similar association is found in girls.The findings warrants further longitudinal study.
