近年来,高血压发病一直呈上升趋势,值得注意的是,目前高血压病患者的年龄在提前。医学研究表明,成人的原发性高血压始于儿童期,儿童期血压偏高是日后高血压病的潜在因素。据统计,血压偏高的儿童约占同龄儿童的10％左右。专家认为,预防高血压应从儿童抓起。祖国医学提倡“未病先防,有病早治”。哪些儿童易患高血压,又如何预防呢?从高血压的发病来看,多数都有家庭遗传病史。有人做了这样的调查:在父母双方均有高血压、只有一方有高血压及双方均无高血压的家庭,其子女高血压患病率分别为45％、28％、3.8％。但是,后天因素也起着重要作用,其中肥胖最危险。肥胖儿因机体代谢需要,心脏排血量及血容量均较正常儿童高,久之就会造成血压升高及心脏肥大。据统计,50％以上的高血压儿童是肥胖儿。此外,食盐过多、精神紧张、缺乏锻炼、吸烟、饮酒等也都可导致高血压。临床实践证明,许多有高血压家庭史的儿童,如果注意避免后天不良因素的影 In recent years, the incidence of hypertension has been on an upward trend, it is noteworthy that the current age of hypertensive patients in advance. Medical research shows that adult essential hypertension starts in childhood, high blood pressure in childhood is a potential factor for future hypertension. According to statistics, children with high blood pressure account for about 10% of children of the same age. Experts believe that prevention of hypertension should start from children. Motherland medicine advocates “not disease prevention, sick early treatment.” Which children are susceptible to hypertension, and how to prevent it? From the incidence of hypertension, most have a family history of heredity. Someone has done such a survey: in both parents have high blood pressure, only one side has high blood pressure and hypertension in both families, the prevalence of hypertension in their children were 45%, 28%, 3.8%. However, acquired factors also play an important role, of which obesity is the most dangerous. Obese children due to body metabolism, cardiac output and blood volume were higher than normal children, a long time will cause high blood pressure and cardiac hypertrophy. According to statistics, more than 50% of hypertensive children are obese children. In addition, too much salt, nervousness, lack of exercise, smoking, drinking, etc. can also lead to high blood pressure. Clinical practice has proved that many children with family history of hypertension, if attention to avoid the adverse effects of acquired
