During 1973 through 1975, more than 1 million persons were screened in the nationwide Community Hypertension Evaluation Clinic (CHEC) program at 1,171 sites. While those screened were not from defined populations, findings paralleled those of recent surveys of US population samples. First, CHEC confirmed the scope of the problem of elevated blood pressure in the United States. Of those screened, 247 of 1,000 had a diastolic reading of 90 mm Hg or higher; 116 of 1,000 had a reading of 95 mm Hg or greater. Prevalence of elevated blood pressure rose with age up to age 50 years, was higher in blacks than in whites, and was higher in men than in women. Second, CHEC data confirmed the challenge of undetected, untreated, and uncontrolled hypertension. Previously undetected hypertension was present in 27.7% of hypertensive people, detected but untreated in 10.7%, and treated but uncontrolled in 16.7%--totaling 55.1%.
在1973年至1975年期间，全国范围内的社区高血压评估诊所（CHEC）项目在1171个地点对超过100万人进行了筛查。虽然接受筛查的人群并非来自特定人群，但研究结果与近期美国人口样本调查的结果相似。首先，CHEC证实了美国高血压问题的严重程度。在接受筛查的人群中，每1000人中有247人舒张压读数为90毫米汞柱或更高；每1000人中有116人读数为95毫米汞柱或更高。高血压患病率随年龄增长至50岁，黑人高于白人，男性高于女性。其次，CHEC数据证实了未被发现、未治疗和未控制的高血压所带来的挑战。以前未被发现的高血压在27.7%的高血压患者中存在，已被发现但未治疗的占10.7%，已治疗但未得到控制的占16.7%——总计55.1%。
