目的：探讨某军医大学学生2013 年某一时段营养及体能情况，以提高军校医学生身体素质。方法：选取2013 年1 月～2013 年2 月某军医大学在学校餐厅集体就餐的学员682 人，采用称重法调查膳食，测定学员体重、身高，计算体重指数（BMI），对学员的体能状况进行测试。结果：调查学生蛋类、食用油摄入过多，而禽肉、豆类、蔬菜、牛奶、水果等均低于军标；Vit A、Vit C 以及钙元素每日摄入量明显不足；学生每日获得热能的分配比例较好，均已达到军标；调查学生中男生体能状况优于女生（x2=22.035，P<0. 001），女生的超重人数明显多于男生（x2=20.142，P<0.001）。结论：建议该校对餐厅炊事人员增加供应学生的食物品种，特别是水产、牛奶等富含优质蛋白的食品；强化学生体育锻炼的监督和指导工作，帮助他们增强自身体质，为国防现代化服务。
