Recently the Joint National Committee (7th report) introduced the term "pre-hypertension." Little is known on its prevalence in the general population.
To assess the prevalence of pre-hypertension in a large national cohort.
We analyzed the database of all > or = 18 year old members of Leumit Health Services, one of the four health management organizations in Israel, from which we retrieved the recorded blood pressure levels. Pre-hypertension was defined according to the JNC-7 criteria.
Of the 426,033 subjects 18.6% had a diagnosis of hypertension or used antihypertensive medications. Only 40.8% of the other 346,799 subjects had had their BP measured in the preceding 2 years. BP recording rates were higher in females than in males (45.1% vs. 36.3%) and higher in elderly subjects than in young subjects (56% aged 66-75 years vs. 32% aged 18-25). Pre-hypertension was observed in 80,625 (23.2%) of the 346,799 while only 56,113 (16.2%) had normal BP records. The prevalence of pre-hypertension increased with age (13.3% aged 18-25 vs. 44.8% aged 66-75), and was more prevalent in men than in women (24.0% vs. 22.5%).
BP levels among young people are low, even though the prevalence of pre-hypertension in this population may be high. Thus, more emphasis should be given to routine BP measurements and confirmation of the findings in all age groups.
最近，美国国家联合委员会（第七次报告）引入了“高血压前期”这一术语。对于其在普通人群中的患病率了解甚少。
评估一个大型全国队列中高血压前期的患病率。
我们分析了以色列四大健康管理组织之一的Leumit健康服务机构中所有年龄≥18岁成员的数据库，从中获取记录的血压水平。高血压前期根据美国国家联合委员会第七版标准定义。
在426,033名受试者中，18.6%被诊断为高血压或正在使用抗高血压药物。在另外346,799名受试者中，只有40.8%在之前两年内测量过血压。女性的血压记录率高于男性（45.1%对36.3%），老年受试者的血压记录率高于年轻受试者（66 - 75岁年龄段为56%，18 - 25岁年龄段为32%）。在346,799名受试者中，80,625名（23.2%）患有高血压前期，而只有56,113名（16.2%）血压记录正常。高血压前期的患病率随年龄增长而增加（18 - 25岁年龄段为13.3%，66 - 75岁年龄段为44.8%），男性比女性更普遍（24.0%对22.5%）。
尽管该人群中高血压前期的患病率可能较高，但年轻人的血压水平较低。因此，应更加重视所有年龄组的常规血压测量及结果确认。
