Approximately one in five ex-smokers reduces or maintains weight after smoking cessation but little is known about who succeeds to avoid weight gain. The purpose of this study was to identify predictors of weight reduction after long-term smoking cessation in a general population.
Data was obtained from two Danish population-based cohorts (the Inter99 and the Helbred2006 study). Anthropometric measurements were performed by trained research staff. Out of 3.577 daily smokers at baseline 317 participants had quit smoking at the five-year follow-up for at least one year. Multiple logistic regression analysis was performed to determine predictors of weight reduction.
Thirteen percent reduced weight by at least 1 kg and 4% maintained their weight. Quitters with obesity had more than seven times higher odds than normal weight quitters to lose weight (OR 7.13 (95% CI 2.76-19.71)), and they had the largest median weight loss of 4.45 kg. The only other significant predictor of weight reduction was low tobacco consumption at baseline.
Predictors of weight reduction after smoking cessation were high body mass index and low tobacco consumption at baseline. This study might motivate smokers with obesity to quit smoking and health professionals to give them support.
大约五分之一的戒烟者在戒烟后体重减轻或保持不变，但对于哪些人能成功避免体重增加却知之甚少。本研究的目的是确定普通人群中长期戒烟后体重减轻的预测因素。
数据来自两个丹麦基于人群的队列研究（Inter99和Helbred2006研究）。人体测量由训练有素的研究人员进行。在基线时的3577名每日吸烟者中，有317名参与者在五年随访时已戒烟至少一年。进行多因素逻辑回归分析以确定体重减轻的预测因素。
13%的人体重减轻至少1千克，4%的人体重保持不变。肥胖的戒烟者体重减轻的几率比正常体重的戒烟者高出七倍多（比值比7.13（95%置信区间2.76 - 19.71）），且他们的中位数体重减轻最大，为4.45千克。体重减轻的唯一其他显著预测因素是基线时烟草消费量低。
戒烟后体重减轻的预测因素是基线时高体重指数和低烟草消费量。本研究可能会促使肥胖吸烟者戒烟，并促使健康专业人员给予他们支持。
