To quantify the association between body mass index (BMI) and smoking (at all and daily smoking) stratified by gender, family social class, and ethnicity among adolescents aged between 13 and 15.
The analyses were based on the Danish contribution to the international Health Behaviour in School-aged Children survey in 2002 with self-reported data on height, weight, and smoking behaviour. The study population comprised 3,072 students aged between 13 and 15 (1,512 boys and 1,560 girls). Logistic regression analysis was used to quantify the association.
Odds of at all smoking by BMI (per step) was 1.10 (95% CI 1.03-1.17) among boys but there was no association among girls (OR 0.98, 95% CI 0.93-1.04). No significant association was found for daily smoking and BMI. The association between at all smoking and BMI (per step) was significant among boys of middle social class (OR 1.13, 95% CI 1.03-1.24) and Danish ethnicity (OR 1.10, 95% CI 1.02-1.19).
Significant association exists between smoking and BMI among boys of Danish ethnicity and middle family social class only.
定量分析青少年性别、家庭社会阶层和种族对体重指数（BMI）与吸烟（无论是否吸烟和每日吸烟）之间关系的影响。
本研究基于丹麦 2002 年对国际青少年健康行为调查的贡献，采用自我报告的身高、体重和吸烟行为数据。研究对象为 3072 名 13 至 15 岁的学生（男生 1512 名，女生 1560 名）。采用逻辑回归分析来定量分析相关性。
在男生中，BMI（每一步）与无论是否吸烟的相关性为 1.10（95%CI 1.03-1.17），但在女生中没有相关性（OR 0.98，95%CI 0.93-1.04）。BMI 与每日吸烟之间无显著相关性。在中产阶级社会阶层的男生（OR 1.13，95%CI 1.03-1.24）和丹麦裔男生（OR 1.10，95%CI 1.02-1.19）中，无论是否吸烟与 BMI 之间的关联具有统计学意义。
仅在丹麦裔和中产阶级社会阶层的男生中，吸烟与 BMI 之间存在显著关联。
