To investigate the relationship between body mass index (BMI) and smoking.
Participants (N = 2243) provided demographic, height, weight, smoking information through a survey conducted on smokefree.gov and women.smokefree.gov websites. Analysis assessed associations among BMI, smoking status, and cigarettes smoked per day (CPD).
The average (SD) BMI of never, former, intermittent, and daily smokers was 26.3 (6.2), 27.9 (6.5), 27.4 (6.7) and 28.1 (6.8) respectively. Daily (31.2%) and former (32.3%) were more likely to be to be obese compared to never (22.0%) and intermittent (26.1%) smokers. Odds of being obese increased with number of CPD adjusting for potential confounders.
Smokers may currently have BMIs similar to the general population. BMI and CPD were positively correlated.
探讨体重指数（BMI）与吸烟之间的关系。
参与者（N = 2243）通过在无烟.gov和女性无烟.gov网站上进行的一项调查提供了人口统计学、身高、体重和吸烟信息。分析评估了BMI、吸烟状况和每日吸烟量（CPD）之间的关联。
从不吸烟、曾经吸烟、偶尔吸烟和每日吸烟者的平均（标准差）BMI分别为26.3（6.2）、27.9（6.5）、27.4（6.7）和28.1（6.8）。与从不吸烟（22.0%）和偶尔吸烟（26.1%）者相比，每日吸烟（31.2%）和曾经吸烟（32.3%）者更有可能肥胖。在调整潜在混杂因素后，肥胖几率随CPD数量的增加而增加。
目前吸烟者的BMI可能与普通人群相似。BMI与CPD呈正相关。
