Obesity is a serious health problem with an incidence that is increasing rapidly. Enlisted men are a distinctive group characterised by 24-hour community-living and are likely to experience changes in body weight as a result of regular diet and exercise during enlistment.
This study reviewed data from the Second Military Health Survey. Changes in body mass index (BMI) before and during military service were analysed using paired t-test. We calculated OR and 95% CI for factors affecting weight improvement during military service through logistic regression.
The mean BMI in the underweight group increased by 5.87 kg/m during service, while that in the normal weight group increased by 1.18 kg/m. In contrast, the mean BMI in the overweight group decreased by 5.47 kg/m during service. The OR for an improved BMI in the subjective good health group compared with the subjective poor health group was statistically significant (OR=1.71, 95% CI 1.02 to 2.87). The OR for an improved BMI was significantly higher in the group with three or more times per week of strength training than in the group with one to two times per week of strength training, and was higher among the marines compared with the Army soldiers (OR=1.48, 95% CI 1.03 to 2.12 and OR=2.15, 95% CI 1.07 to 4.32, respectively).
Strength training showed a statistically significant increase in BMI during military service. Furthermore, the BMI of men who were underweight before their service increased, while it decreased among those who were overweight.
肥胖是一个严重的健康问题，其发病率正在迅速上升。入伍男性是一个独特的群体，其特点是 24 小时社区生活，并且由于入伍期间的规律饮食和锻炼，他们的体重可能会发生变化。
本研究回顾了第二次军事健康调查的数据。使用配对 t 检验分析了入伍前后体重指数（BMI）的变化。我们通过逻辑回归计算了影响入伍期间体重改善的因素的 OR 和 95%CI。
体重不足组的平均 BMI 在服役期间增加了 5.87kg/m，而正常体重组的平均 BMI 增加了 1.18kg/m。相比之下，超重组的平均 BMI 在服役期间下降了 5.47kg/m。与主观健康状况差的组相比，主观健康状况好的组 BMI 改善的 OR 具有统计学意义（OR=1.71，95%CI 1.02 至 2.87）。每周进行三次或以上力量训练的组与每周进行一到两次力量训练的组相比，BMI 改善的 OR 显著更高，而与陆军士兵相比，海军陆战队的 OR 更高（OR=1.48，95%CI 1.03 至 2.12 和 OR=2.15，95%CI 1.07 至 4.32）。
力量训练在服役期间显示出 BMI 有统计学意义的增加。此外，服务前体重不足的男性的 BMI 增加，而超重的男性的 BMI 则下降。
