To investigate the relationship between the anxiety and blood pressure (BP) and heart rate (HR) increase in peri-exam period. Sixty-four college students(20.0 ± 0.1 year old) were included in this study. The BP and HR were measured in the morning and in the evening for 3 days during the prereview (ba), review, and exam periods. The BP and HR increase amplitudes (HRIA) of review and exam periods were from the difference of corresponding values and basic values, and the BPIA/baBP and HRIA/baHR were calculated. All of the students completed the Self-Rating Anxiety score (SAS) questionnaire the first day of the exam period. Scores over 50 points were used as the standard for anxiety. From the prereview to exam periods, the BP and HR increased gradually. The exam SBPIA (4.3 ± 1.3 vs. 0.3 ± 0.5 mmHg, P < 0.05) and DBPIA (4.4 ± 1.5 vs. 1.0 ± 0.5 mmHg, P < 0.05) were significantly higher in the anxiety group than in the no-anxiety group. The SBPIA/DBPIA and HRIA showed a similar profile also(9.7 ± 2.1 vs. 1.9 ± 0.9 bpm, P < 0.05). Strong positive correlations were found between the SAS score and BPIA and HRIA both in the review and exam period. The smoking group and family hypertension group had higher anxiety score; meanwhile, their exam BPIAs and HRIAs were significantly higher than their corresponding group. The BP and HR increase in the review and exam period, anxiety is an important factor of BP and HR increase.
为了研究考试期间焦虑与血压（BP）和心率（HR）升高之间的关系。本研究纳入了 64 名大学生（20.0±0.1 岁）。在预习期（ba）、复习期和考试期间的 3 天内，每天早上和晚上测量 BP 和 HR。复习期和考试期的 BP 和 HR 升高幅度（HRIA）是相应值与基础值的差值，计算 BPIA/baBP 和 HRIA/baHR。所有学生在考试期的第一天完成了自评焦虑量表（SAS）问卷。得分超过 50 分被用作焦虑的标准。从预习期到考试期，BP 和 HR 逐渐升高。考试期 SBPIA（4.3±1.3 比 0.3±0.5mmHg，P<0.05）和 DBPIA（4.4±1.5 比 1.0±0.5mmHg，P<0.05）在焦虑组明显高于无焦虑组。SBPIA/DBPIA 和 HRIA 也呈现出相似的趋势（9.7±2.1 比 1.9±0.9bpm，P<0.05）。在复习期和考试期，SAS 评分与 BPIA 和 HRIA 之间均存在强烈的正相关。吸烟组和家族高血压组的焦虑评分较高；同时，他们的考试期 BPIA 和 HRIAs 明显高于相应组。复习期和考试期的 BP 和 HR 升高，焦虑是 BP 和 HR 升高的重要因素。
