Weight gain and concerns about weight can influence a smoker's ability to successfully quit, and young adults are a subgroup of smokers who are particularly concerned about the impact of quitting on their body weight. This study explored the associations between body mass index, weight perceptions, and smoking status among young adults.
The sample consisted of 4027 young adults between the ages of 18 and 29 who participated in a randomized control trial of the National Cancer Institute's SmokefreeTXT program. Multivariable logistic regression models were used to examine the associations between weight related variables and smoking status.
Obese participants had a 0.72 lower odds (95% CI: 0.62, 0.85) of reporting smoking at the end of the program than participants of normal weight, and this difference persisted over time. Weight perceptions were also associated with smoking status. Those who perceived themselves to be slightly underweight/underweight were more likely to report smoking than those who reported being just about the right weight (OR: 1.53, 95% CI: 1.20, 1.95), and those who strongly disagreed that smoking cigarettes helps people keep their weight down were less likely to report smoking at the end of treatment than those who neither agreed nor disagreed with this statement (OR: 0.69, 95% CI: 0.54, 0.87).
Weight related factors assessed at baseline predicted smoking status at the end of treatment and through long term follow-up. Smoking cessation programs that tailor content to addresses the specific needs of weight concerned smokers may enhance effectiveness.
This study explores the association between weight related factors and smoking status among young adults, a priority population for smoking cessation efforts. This study demonstrates that both actual weight and weight perceptions (eg, perception of body weight, perception of associations between smoking and weight) are associated with smoking outcomes, and thus need to be a considered in the development of smoking cessation programs.
体重增加和对体重的担忧会影响吸烟者成功戒烟的能力，而年轻成年人是特别关注戒烟对体重影响的吸烟者亚组。本研究探讨了年轻成年人的体重指数、体重认知与吸烟状况之间的关系。
该样本由 4027 名年龄在 18 至 29 岁之间的年轻人组成，他们参加了美国国家癌症研究所的 SmokefreeTXT 项目的一项随机对照试验。多变量逻辑回归模型用于研究与体重相关的变量与吸烟状况之间的关联。
与体重正常的参与者相比，肥胖参与者在项目结束时报告吸烟的几率低 0.72（95%CI：0.62，0.85），这种差异随着时间的推移而持续存在。体重认知也与吸烟状况有关。那些认为自己有点偏轻/体重不足的人比那些报告体重刚好合适的人更有可能报告吸烟（OR：1.53，95%CI：1.20，1.95），而那些强烈不同意吸烟有助于人们保持体重的人比那些既不同意也不赞成这一说法的人在治疗结束时报告吸烟的可能性更小（OR：0.69，95%CI：0.54，0.87）。
基线评估的体重相关因素预测了治疗结束时和长期随访时的吸烟状况。针对关注体重的吸烟者的具体需求定制内容的戒烟计划可能会提高效果。
本研究探讨了体重相关因素与年轻成年人吸烟状况之间的关系，这是戒烟工作的重点人群。本研究表明，实际体重和体重认知（例如，对体重的认知、对吸烟与体重之间关系的认知）都与吸烟结果相关，因此需要在戒烟计划的制定中加以考虑。
