Smoking cessation and improvement in physical performance among young men.
Tobacco use among young adults is a major public health challenge. Near-term benefits of cessation may motivate active young people to quit or avoid smoking. Military basic training includes mandatory tobacco cessation, as well as uniform physical conditioning regimes, creating an opportunity to evaluate changes in physical performance metrics in direct relation to smoking cessation. These analyses included data from all men who completed Marine Corps recruit training in San Diego, California, between 2002 and 2006. Recruits reported tobacco use and other health metrics on a pretraining survey. Initial and final aerobic run-times were recorded over the 3-month training period. Multivariable linear regression analyses assessed changes in run-speed relative to pre-enlistment smoking history. Among 52,419 young men included in analyses, 13,248 (25.3%) reported smoking before enlistment. Average run-speeds improved among all groups of recruits; however, improvement was greater among prior smokers compared to recruits with no history of smoking (average increase of 0.31 vs. 0.21 miles per hour) and statistically significant in multivariate analyses. Smoking cessation in this cohort of young men resulted in improved physical aerobic performance, independent of other behavioral health characteristics. These data may be useful in promoting and motivating smoking cessation among young, active adults.
