测定３０例重点班和３２例非重点班的中学生，在不同学习强度或考试应激状况下的血清脂质水平。结果显示，应激对血脂的影响，主要表现为血清总胆固醇（ＴＣＨ）和高密度脂蛋白（ＨＤＬ）水平的增高。由于重点班学生对考试的应激反应强度小于非重点班学生，提示平时加强学习以减轻考试的应激反应性，似有利于学生的心理健康。 Serum lipid levels were measured at different learning intensities or under stressful conditions in 30 high school and 32 non-key middle school students. The results showed that the impact of stress on blood lipids, mainly as serum total cholesterol (TCH) and high-density lipoprotein (HDL) levels increased. Due to the intensity of the stress response of the key students to the exam is less than that of the non-key students, it is suggested that strengthening the learning usually reduces the stress reactivity of the test, which seems to be beneficial to the mental health of the students.
