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

Abstract

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 (χ ²= 7.23), gender (χ ² = 83.01), school status (χ ² = 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.

Abstract

【摘要】 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 家庭追踪调査(CFPS 2018)中的1 057名青少年为调査对象, 调査其吸烟与体育锻炼情况, 采用χ ²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(χ ² = 7.23)、性别(χ ² = 83.01)、上学状态(χ ² = 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。
