This follow-up study investigated the relationship between changes in physical fitness and exercise habits during the 1st and 4th years in healthy medical college students. We also investigated the relation between exercise habits and the lifestyle factors during the same period of time. The subjects were 229 male and 126 female student volunteers who received physical fitness tests and questionnaires (lifestyles and exercise habits) in both the 1st and 4th years. The results were as follows: 1. A significant association between increment in physical fitness and exercise habits was shown by the fitness score in the 1st year, and the intensity and frequency of exercise in the 4th year in males. In females, an association was found in the intensity of exercise during the 1st year, and frequency of exercise during the 4th year. The intensity in 4th year among males (odds ratio(OR): 2.80, 95% confidence interval (CI): 1.33-5.87) and the frequency during the 4th year among females (OR: 5.63, 95% CI: 2.36-13.43) were associated with a higher odds ratios for improvement in physical fitness than other factors related to exercise habits in 4th year medical students. 2. In the association between exercise habits related to increment in physical fitness and other lifestyles, a significant association was admitted between the intensity of exercise and the frequency of eating breakfast during the 4th year in males (OR: 2.18, 95% CI: 1.11-4.28). These results suggested that the intensity of exercise during the 4th year in males and the frequency of exercise during the 4th year in females were associated with increments in physical fitness for follow-up. A lifestyle factor related to the intensity in exercise habits has been suggested to be the frequency of eating breakfast (more than 5 days/week) in males.
这项随访研究调查了健康医科大学生在第1年和第4年期间身体素质变化与运动习惯之间的关系。我们还调查了同一时期运动习惯与生活方式因素之间的关系。研究对象为229名男学生和126名女学生志愿者，他们在第1年和第4年都接受了身体素质测试和问卷调查（生活方式和运动习惯）。结果如下：1. 第1年的身体素质得分以及第4年男性的运动强度和频率显示出身体素质提高与运动习惯之间存在显著关联。在女性中，发现第1年的运动强度与第4年的运动频率之间存在关联。第4年男性的运动强度（优势比（OR）：2.80，95%置信区间（CI）：1.33 - 5.87）和第4年女性的运动频率（OR：5.63，95%CI：2.36 - 13.43）与四年级医学生中与运动习惯相关的其他因素相比，身体素质改善的优势比更高。2. 在与身体素质提高相关的运动习惯和其他生活方式之间的关联中，第4年男性的运动强度与吃早餐的频率之间存在显著关联（OR：2.18，95%CI：1.11 - 4.28）。这些结果表明，男性第4年的运动强度和女性第4年的运动频率与随访期间的身体素质提高有关。对于男性而言，与运动习惯强度相关的一个生活方式因素被认为是吃早餐的频率（每周超过5天）。
