高龄人口逐年增多,老年病亦随之增多。老年病中以脑卒中、心脏病为主,而最重要的血管病变促进因子为高血压等动脉病变。老年病的预防,应在青年时期开始。对高血压亦应如此,对血压较高者应给予适当的指导。一、定义青年高血压病并非专指某一特定的疾病或病理表现。在探讨其定义时应对其年龄范围及血压值制定一标准。1.年龄标准:欧美多将15岁之小儿期及20岁左右以前青春期(adolescence)的高血压统称为青年(jnvenile)高血压,有时亦包括30岁左右者。作者认为应以血管自然变化较少的30岁以前为对象。但目前尚无统一的规定。2.血压值标准:集团检查或流行病学调查时,一般按WHO规定,以140～159和/(或)90～94为临界高血压;以160以上和/(或)95以上为高血压;以140/90以下为正常血压。但此规定已被应用于所有年龄组,是否亦应适 The elderly population increased year by year, elderly also increased. Stroke and heart disease are the main causes of senile diseases, while the most important vascular disease promoting factors are arterial diseases such as hypertension. Prevention of geriatric diseases should start in youth. The same should be true for high blood pressure, high blood pressure should be given appropriate guidance. First, the definition of youth hypertension is not specific to a particular disease or pathological manifestations. When discussing its definition, a standard should be set for its age range and blood pressure values. 1. Age standards: Europe and the United States and more will be 15-year-old infancy and adolescence before the age of 20 (adolescence) hypertension are collectively referred to as jnvenile hypertension, sometimes including 30-year-olds. The authors believe that the natural changes in blood vessels should be less before the age of 30 as the object. But there is no uniform regulation yet. 2. Blood pressure standard: group inspection or epidemiological survey, generally according to WHO regulations, to 140 ~ 159 and / or 90 ~ 94 as the critical hypertension; more than 160 and / or 95 or more for the hypertension ; Below 140/90 normal blood pressure. However, this provision has been applied to all age groups and should be appropriate
