目的:探讨中学教师动态血压(ABP)的变化。方法:采用24小时动态血压仪对100例健康教师进行监测。结果:各年龄组收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)、心率(HR)相差数值较小,但血压负荷男女之间相差较大,男性SBP 4.26％,DBP 6.54％;女性SBP 1.85％,DBP4.96％;差别显著(P<0.01)。血压负荷舒张压高于收缩压,差别显著(P<0.01),同一受试者在不同状态下,动态血压参数有不同程度的变化。结论:推荐中学教师24小时动态血压均值<130/80mmHg(1mmHg=0.133kPa),日间(6～22时)均值<135/85mmHg,夜间(22～6时)均值<125/75mmHg,夜间血压下降率>8％作为中学教师动态血压正常参照值。
Objective: To investigate the changes of ambulatory blood pressure (ABP) in middle school teachers. Methods: 100 healthy teachers were monitored with a 24-hour dynamic blood pressure monitor. Results: SBP, DBP, MAP, and heart rate (HR) differences were small in all age groups, but there was a large difference between the blood pressure load and the men’s SBP 4.26%. DBP 6.54 %; female SBP 1.85%, DBP4.96%; difference was significant (P <0.01). The diastolic blood pressure was higher than that of systolic blood pressure, and the difference was significant (P<0.01). The ambulatory blood pressure parameters varied in varying degrees in the same subject under different conditions. Conclusion: It is recommended that 24-hour ambulatory blood pressure of middle school teachers is less than 130/80mmHg (1mmHg=0.133kPa), average daytime (6～22hrs) is less than 135/85mmHg, and nighttime (22～6hrs) is less than 125/75mmHg. The rate of decline was >8% as a reference value for normal blood pressure in secondary school teachers.
