Weight control is cited by some people, especially adolescent girls, as a reason for commencing smoking or not quitting. The aim of this study was to explore the relationship between smoking behaviour and being overweight or obese, overall and by age and sex sub-groups.
We used data from the six Scottish Health Surveys conducted to date (1995-2010) to undertake a population-based, cross-sectional study on 40,036 participants representative of the adult (≥16 years) Scottish population. Height and weight were measured by a trained interviewer, not self-reported.
24,459 (63.3%) participants were overweight (BMI ≥25 kg/m²) and 9,818 (25.4%) were obese (BMI ≥30 kg/m²). Overall, current smokers were less likely to be overweight than never smokers. However, those who had smoked for more than 20 years (adjusted OR 1.54, 95% CI 1.41-1.69, p < 0.001) and ex-smokers (adjusted OR 1.18, 95% CI 1.11-1.25, p < 0.001) were more likely to be overweight. There were significant interactions with age. Participants 16-24 years of age, were no more likely to be overweight if they were current (adjusted OR 1.01, 95% CI 0.84-1.20, p = 0.944) or ex (adjusted OR 0.88, 95% CI 0.67-1.14, p = 0.319) smokers. The same patterns pertained to obesity.
Whilst active smoking may be associated with reduced risk of being overweight among some older adults, there was no evidence to support the belief among young people that smoking protects them from weight gain. Making this point in educational campaigns targeted at young people may help to discourage them from starting to smoke.
一些人，尤其是青少年女孩，将控制体重作为开始吸烟或不戒烟的原因之一。本研究旨在探讨吸烟行为与超重或肥胖之间的关系，包括总体情况以及按年龄和性别亚组的情况。
我们使用迄今为止进行的六项苏格兰健康调查（1995-2010 年）的数据，对代表成年（≥16 岁）苏格兰人群的 40036 名参与者进行了一项基于人群的横断面研究。身高和体重由经过培训的访谈者测量，而不是自我报告。
24459 名（63.3%）参与者超重（BMI≥25kg/m²），9818 名（25.4%）参与者肥胖（BMI≥30kg/m²）。总体而言，当前吸烟者超重的可能性低于从不吸烟者。然而，那些吸烟超过 20 年（调整后的 OR 1.54，95%CI 1.41-1.69，p<0.001）和戒烟者（调整后的 OR 1.18，95%CI 1.11-1.25，p<0.001）更有可能超重。年龄存在显著交互作用。16-24 岁的参与者，如果是当前吸烟者（调整后的 OR 1.01，95%CI 0.84-1.20，p=0.944）或戒烟者（调整后的 OR 0.88，95%CI 0.67-1.14，p=0.319），超重的可能性并没有增加。肥胖的情况也是如此。
虽然在一些老年人中，主动吸烟可能与超重风险降低有关，但没有证据支持年轻人的观点，即吸烟可以防止体重增加。在针对年轻人的教育活动中强调这一点，可能有助于劝阻他们开始吸烟。
