Age changes in arterial pressure (AP) and incidence of arterial hypertension (AH), as well as probability of developing IHD, were compared between school teachers and a control group sustaining no excessive occupational stress. The investigated teachers, numbering 168, were from Sofia public schools and technical schools. The control group consisted of 103 women: office employees, designers, research workers, etc. Findings indicated teachers to have a closer age relationship to AP level, compared to controls. Considerable increase in systolic AP was observed after 45 years of age, and there was a significant difference between the first and the second halves of the 4th decade. Diastolic AP was also higher in teachers than in controls. Duration of teaching experience proved to be strongly correlated with systolic and diastolic AP levels (r = 0.56, p < 0.001; and r = 0.50, p < 0.001). Beyond 40 years of age, teachers showed a high incidence of AH, 31%. The group as a whole was at high cardiovascular risk.
对学校教师和未承受过度职业压力的对照组进行了动脉血压（AP）的年龄变化、动脉高血压（AH）发病率以及患缺血性心脏病（IHD）可能性的比较。接受调查的168名教师来自索非亚的公立学校和技术学校。对照组由103名女性组成：办公室职员、设计师、研究人员等。研究结果表明，与对照组相比，教师的年龄与AP水平的关系更为密切。45岁以后收缩压AP显著升高，且在第四个十年的前半期和后半期之间存在显著差异。教师的舒张压AP也高于对照组。教学经验的时长与收缩压和舒张压AP水平密切相关（r = 0.56，p < 0.001；r = 0.50，p < 0.001）。40岁以后，教师的AH发病率较高，为31%。总体而言，该组存在较高的心血管风险。
