在近期组织的一次中学生保健体检中,发现约有10％左右的中学生血压偏低,其中女生较多。其收缩压多在70～85毫米汞柱之间,而舒张压常低于60毫米汞柱。据了解,这些低血压学生中大多不爱好体育运动,并且体质与营养状况都较差。正常人的血压可因年龄、性别、体质等不同而有一定的变异范围。学生出现低血压大多属于原发性低血压,这种低血压通常无明确器质性疾病,相当一部分学生只是由于缺乏体育锻炼和体质较差造成的。若这种低血压现象持续时间太长,势必影响学生的智力和生长发育,以致在学习时注意力不集中,反应迟钝,记忆力下降,同时还会造成机体的抵抗能力降低,容易患多种疾病。
In a recent health examination organized by a middle school student, it was found that about 10% of middle school students had low blood pressure, including more girls. The systolic blood pressure more than 70 to 85 mm Hg, and diastolic blood pressure often less than 60 mm Hg. It is understood that most of these hypotension students do not like sports, and physical and nutritional status are poor. Normal blood pressure due to age, gender, physical and other differences have a certain range of variation. Low blood pressure students mostly belong to the primary hypotension, this hypotension is usually no clear organic disease, a considerable part of the students just because of lack of physical activity and poor physical condition. If the duration of this hypotensive effect is too long, it is bound to affect students’ intelligence and growth and development, so that learning inattention, unresponsive, memory loss, but also reduce the body’s resistance, susceptible to a variety of diseases .
