Obesity is a risk factors of chronic diseases, and smoking is associated with both chronic diseases and obesity. There were some controversies about the associations between smoking and obesity. Thus, our study aimed to explore the associations of smoking with obesity, using body mass index (BMI) and waist circumference (WC) as obesity indices in northeast China. We enrolled a sample of 16,412 participants in Jilin province aged 18-79 in this study, which were derived from a cross-sectional survey in 2012. We used quantile regression (QR) models to identify the associations of smoking with obesity in different quantiles of BMI (or WC) by genders. The differences of BMI and WC by genders were statistically significant (p < 0.05). In conclusion, compared with current non-smokers, current smokers had lower BMI but higher WC. As increasing of WC, the association of WC with smoking was getting stronger, especially in females.
肥胖是慢性病的危险因素,而吸烟既与慢性病有关,也与肥胖有关。吸烟与肥胖之间的关系存在一些争议。因此,我们的研究旨在探讨吸烟与肥胖的关系,在中国东北地区使用体重指数(BMI)和腰围(WC)作为肥胖指标。我们从 2012 年的一项横断面调查中招募了 16412 名 18-79 岁的吉林省参与者作为研究样本。我们使用分位数回归(QR)模型按性别在 BMI(或 WC)的不同分位数识别吸烟与肥胖之间的关系。性别之间的 BMI 和 WC 差异具有统计学意义(p<0.05)。总之,与当前不吸烟者相比,当前吸烟者的 BMI 较低,但 WC 较高。随着 WC 的增加,WC 与吸烟的关系越来越强,尤其是在女性中。
