To investigate the magnitude and consistency of the associations between smoking and body mass index (BMI) in different populations.
A cross sectional study.
About 69,000 men and women aged 35-64 years from 42 populations participating in the first WHO MONICA survey in the early and mid 1980s.
Compared to never smokers, regular smokers had significantly (p < 0.05) lower median BMI in 20 (men) and 30 (women) out of 42 populations (range -2.9 to 0.5 kg/m2). There was no population in which smokers had a significantly higher BMI than never smokers. Among men, the association between leanness and smoking was less apparent in populations with relatively low proportions of regular smokers and high proportions of ex-smokers. Ex-smokers had significantly higher BMI than never smokers in 10 of the male populations but in women no consistent pattern was observed. Adjustment for socioeconomic status did not affect these results.
Although in most populations the association between smoking and BMI is similar, the magnitude of this association may be affected by the proportions of smokers and ex-smokers in these populations.
调查不同人群中吸烟与体重指数（BMI）之间关联的程度和一致性。
横断面研究。
20世纪80年代早期和中期参与世界卫生组织首次莫尼卡（MONICA）调查的42个地区的约69000名年龄在35 - 64岁之间的男性和女性。
与从不吸烟者相比，在42个地区中的20个地区（男性）和30个地区（女性），经常吸烟者的BMI中位数显著更低（p < 0.05）（范围为 -2.9至0.5kg/m²）。没有一个地区的吸烟者BMI显著高于从不吸烟者。在经常吸烟者比例相对较低且戒烟者比例较高的地区，男性中消瘦与吸烟之间的关联不太明显。在10个男性群体中，戒烟者的BMI显著高于从不吸烟者，但在女性中未观察到一致的模式。对社会经济状况进行调整并不影响这些结果。
尽管在大多数人群中吸烟与BMI之间的关联相似，但这种关联的程度可能受这些人群中吸烟者和戒烟者比例的影响。
