The investigation carried out on a group of 1221 students (aged 13-19) of an Italian secondary school shows (19.6%) prevalence of high blood pressure. The prevalence was calculated assuming as hypertensive people with blood pressure higher than an arbitrary limit of 140/90 mmHg. The means, standard deviations and 95th percentiles for systolic and diastolic pressure for each age and sex were also calculated. In a follow up of 6 months the percentage of students with BP > 140/90 mmHg decreased from 6.5% to 3.5%. Statistical analysis of 19 items of a questionnaire distributed to be filled to the students shows interesting correlations between BP values, hypertension in relatives and obesity.
对一所意大利中学的1221名学生（年龄在13 - 19岁）进行的调查显示，高血压患病率为19.6%。该患病率是将血压高于任意设定的140/90 mmHg限值的人视为高血压患者计算得出的。还计算了每个年龄和性别的收缩压和舒张压的均值、标准差以及第95百分位数。在为期6个月的随访中，血压> 140/90 mmHg的学生比例从6.5%降至3.5%。对分发给学生填写的一份包含19个项目的问卷进行的统计分析表明，血压值、亲属患高血压情况和肥胖之间存在有趣的相关性。
