背景1978年至1990年间，35至74岁的美国成年人超重的比例男性增加了9.6%，女性增加了8.0%。由于吸烟的流行率在同一时期下降，戒烟已被认为是导致超重流行率上升的一个因素。为了估计戒烟对超重患病率增加的影响，我们分析了1988年至1998年参加第三次全国健康和营养检查调查的5247名35岁或以上成年人的当前和过去体重和吸烟状况的数据。对结果进行了年龄、社会人口学特征、体力活动水平、饮酒量和（女性）产次的调整。在10年的时间里，体重增加与戒烟有关（即，戒烟者的体重增加超过继续吸烟者的体重增加，男性为4.4公斤，女性为5.0公斤。在过去10年内戒烟的吸烟者比从不吸烟的受访者更有可能超重（男性比值比为2.4，女性为2.0）。对于男性来说，大约四分之一（9.6个百分点中的2.3个百分点）和对于女性来说，大约六分之一（8.0个百分点中的1.3个百分点）的超重流行率的增加可以归因于过去10年内的戒烟。虽然戒烟对健康的好处是不可否认的，但戒烟可能与超重患病率的小幅增加有关。
Background. The proportion of U.S. adults, 35 to 74 years of age who were overweight increased by 9.6 percent for men and 8.0 percent for women between 1978 and 1990. Since the prevalence of smoking declined over the same period, smoking cessation has been suggested as a factor contributing to the increasing prevalence of overweight.Methods. To estimate the influence of smoking cessation on the increase in the prevalence of overweight, we analyzed data on current and past weight and smoking status for a national sample of 5247 adults 35 years of age or older who participated in the third National Health and Nutrition Examination Survey, conducted from 1988 through 1998. The results were adjusted for age, sociodemographic characteristics, level of physical activity, alcohol consumption, and (for women) parity.Results. The weight gain over a 10-year period that was associated with the cessation of smoking (i.e., the gain among smokers who quit that was in excess of the gain among continuing smokers) was 4.4 kg for men and 5.0 kg for women. Smokers who had quit within the past 10 years were significantly more likely than respondents who had never smoked to become overweight (odds ratios, 2.4 for men and 2.0 for women). For men, about a quarter (2.3 of 9.6 percentage points) and for women, about a sixth (1.3 of 8.0 percentage points) of the increase in the prevalence of overweight could be attributed to smoking cessation within the past 10 years.Conclusions. Although its health benefits are undeniable, smoking cessation may nevertheless be associated with a small increase in the prevalence of overweight.
