The prevalence of primary and secondary hypertension was determined in a random sample of 7455 Swedish men aged 47 to 54 years. Three hundred and sizty-one men were undergoing treatment for hypertension. Seven hundred and ninety-eight men who had blood pressures above 175/115 mm Hg at preliminary screening were recalled for further blood pressure measurements. Those on treatment and all the untreated men whose blood pressures were still over 175/115 mm Hg then underwent extensive investigation for secondary hypertension. Renal parenchymal hypertension was found in 25 (3-6%) patients, renovascular hypertension in four (0-6%), and other forms of secondary hypertension in 11 (1-6%). The investigation led to surgical treatment in only two cases (0-3%). The low prevalence of secondary hypertension, especially surgically curable forms of hypertension, makes routine screening for these cases unnecessary, at least when patients with hypertension have been found at screening. These data must be taken into account in planning community control programmes in hypertension.
在一个由7455名年龄在47至54岁之间的瑞典男性组成的随机样本中，确定了原发性和继发性高血压的患病率。361名男性正在接受高血压治疗。798名在初步筛查时血压高于175/115 mmHg的男性被召回进行进一步的血压测量。那些正在接受治疗的患者以及所有血压仍高于175/115 mmHg的未治疗男性随后接受了继发性高血压的广泛检查。发现25例（3.6%）患者患有肾实质性高血压，4例（0.6%）患有肾血管性高血压，11例（1.6%）患有其他形式的继发性高血压。该调查仅导致2例（0.3%）患者接受手术治疗。继发性高血压的患病率较低，尤其是可通过手术治愈的高血压形式，这使得对这些病例进行常规筛查没有必要，至少在筛查中发现高血压患者时是这样。在规划社区高血压控制项目时必须考虑这些数据。
