简介：据报道，部署的军人吸烟率高于年龄相仿的平民或非部署男性，但吸烟对这些年轻健康男性身体健康的短期影响尚不清楚。本研究检查了自我报告的吸烟状况和 1-4 年内客观测量的健康状况的变化，同时控制了体重指数 (BMI)。方法：本研究纳入了 2005 年至 2008 年间部署到伊拉克或科威特的美国男性海军人员的大样本。使用混合建模程序来确定导致 BMI 和健康状况纵向变化的因素（通过跑步/步行时间、弯举和俯卧撑来衡量）。结果：整个样本(n = 18,537)，20% 的当前吸烟者比不吸烟者更有可能入伍，更年轻，并且基线时 BMI 测量值较低。此外，与不吸烟者相比，吸烟者 1.5 英里的跑步/步行时间较慢，并且可以做更少的弯举和俯卧撑。跑步/步行时间模型表明，在 4 年多的时间里，吸烟者（与不吸烟者相比）的心肺健康下降率明显更高，即使在控制了 BMI 的变化后也是如此。结论：这些结果呼吁继续关注年轻健康男性的尼古丁使用问题。
Introduction: Cigarette smoking has been reported to be higher among deployed military men than among similarly aged civilian or nondeployed men, but the short-term effect of smoking on physical fitness among these young healthy men is unclear. This study examined self-reported smoking status and change in objectively measured fitness over 1-4 years while controlling for body mass index (BMI).Methods: This study included a large sample of male U. S. navy personnel who deployed to Iraq or Kuwait between 2005 and 2008. A mixed modeling procedure was used to determine factors contributing to longitudinal changes in both BMI and fitness (measured by run/walk times, curl-ups, and push-ups).Results: Of the total sample (n = 18,537), the 20% current smokers were more likely than nonsmokers to be enlisted, younger, and have lower BMI measurements at baseline. In addition, smokers had slower 1.5-mile run/walk times and could do fewer curl-ups and push-ups compared with nonsmokers. The run/walk time model indicated that over 4 years, smokers (compared with nonsmokers) experienced a significantly greater rate of decrease in cardiorespiratory fitness, even after controlling for changes in BMI.Conclusions: These results call for continued attention to the problem of nicotine use among young healthy men.
