The aim of this paper was to investigate the impact of changes in the students' lifestyle during an examination period on their health condition, as evidenced by changes to the body composition and metabolic rates.
The study involved 268 Wroclaw Medical University students (second- and third-year students). The study was performed 3 times (at the beginning of a semester, in the middle of a semester, and in the examination period) and included a completion of a questionnaire on the current lifestyle, as well as measurements of the body composition, the basal metabolic rate, and the waist and hip circumferences. The measurements were carried out with the use of a body composition analyzer (Tanita MC-780 MA) and a tape measure with a waist-hip ratio calculator.
In the examination period, as compared with the rest of the semester, a significant decrease was observed in the metabolic rates, and the body water and muscle mass of the examined students. During that period, there were also more frequent adverse changes in the students' lifestyle. In the studied periods, a correlation was found between changes in the frequency of snacking, consuming sweets and cola drinks, and the alterations of the subjects' body fat mass, i.e., r = 0.161, r = 0.135, and r = 0.143, respectively. In turn, differences in the frequency of drinking wine, physical activity, sleep length, and time devoted to learning correlated with changes in the participants' body water, i.e., r = 0.140, r = 0.152, and r = 0.133 (r = -0.142, r = -0.147), respectively, and muscle mass, i.e., r = 0.141, r = 0.142, and r = 0.126 (r = -0.130, r = -0.142), respectively, and metabolism, i.e., r = 0.127, r = 0.145 and r = 0.135 (r = -0.127, r = -0.135), respectively.
The analysis of the body composition and metabolic rates of the students during an examination period indicates that the changes occurring in various elements of their lifestyle (e.g., dietary habits, physical activity) can result in deteriorating their health condition.

本文旨在研究学生在考试期间生活方式的改变对其健康状况的影响,具体表现为身体成分和代谢率的变化。
本研究纳入了 268 名弗罗茨瓦夫医科大学的学生(二、三年级学生)。研究共进行了 3 次(学期开始时、学期中期和考试期间),包括完成当前生活方式的问卷调查,以及身体成分、基础代谢率和腰围及臀围的测量。测量使用了体成分分析仪(Tanita MC-780 MA)和带有腰臀比计算器的卷尺。
与学期的其他时间相比,考试期间学生的代谢率以及身体水分和肌肉质量显著下降。在此期间,学生的生活方式也发生了更多不良变化。在研究期间,发现了学生吃零食、吃甜食和喝可乐的频率变化与受试者体脂肪量变化之间存在相关性,分别为 r = 0.161、r = 0.135 和 r = 0.143。相反,饮酒、体力活动、睡眠时间和学习时间的频率差异与参与者身体水分的变化相关,分别为 r = 0.140、r = 0.152 和 r = 0.133(r = -0.142、r = -0.147),以及肌肉质量的变化,分别为 r = 0.141、r = 0.142 和 r = 0.126(r = -0.130、r = -0.142),以及代谢率的变化,分别为 r = 0.127、r = 0.145 和 r = 0.135(r = -0.127、r = -0.135)。
对考试期间学生的身体成分和代谢率进行分析表明,他们生活方式的各个方面(如饮食习惯、体力活动)发生的变化可能导致其健康状况恶化。国际职业医学与环境卫生杂志。2020;33(3):339-51。
