The purpose of the present study was to determine the association between smoking and body weight in a cohort of young U.S. Air Force recruits (mean age=20 years) enrolled in basic military training (N=35986). Twenty-two percent of recruits smoked daily prior to basic military training (n=8087) and were compared to never smokers, former smokers, and experimental or nondaily smokers. A three-way interaction among smoking status, gender and ethnicity suggested a small effect for daily smoking among White male recruits only and no significant differences for female recruits or members of any other ethnic group. Although there was a statistically significant relationship between smoking and body weight in White males, the effect size was approximately 1 kg. These results suggest that the energy balance differences in body weight between young smokers and nonsmokers are minimal and that it would take decades to accrue the differences typically seen in adult smokers.
本研究的目的是确定参加基础军事训练的美国年轻空军新兵队列（平均年龄 = 20岁，N = 35986）中吸烟与体重之间的关联。22%的新兵在基础军事训练前每天吸烟（n = 8087），并与从不吸烟者、曾经吸烟者以及偶尔或非每日吸烟者进行比较。吸烟状况、性别和种族之间的三向交互作用表明，仅白人男性新兵中每日吸烟有微小影响，而女性新兵或任何其他种族成员之间无显著差异。尽管白人男性吸烟与体重之间存在统计学上的显著关系，但效应大小约为1千克。这些结果表明，年轻吸烟者与不吸烟者之间体重的能量平衡差异极小，且积累成年吸烟者中常见的差异需要数十年时间。
