Of 177,692 persons screened in 1977 as part of an ongoing City-Wide Hypertension Screening Program in Chicago, 14,988 (8.4%) had diastolic blood pressure (BP) greater than or equal to 95 mm Hg as compared to 13.2% of a similar population in 1976. Only 7% (3,910) of the hypertensive population (diastolic BP greater than or equal to 95 mm Hg or presently on antipressor drugs) had previously undetected hypertension in contrast to 11.9% (4,184) the year before and 48.7% in the same community in 1972. Conversely, 73.2% (40,738) had adequately controlled blood pressure as contrasted to 59.3% (20,897) the previous year and 20.6% in 1972. Of the remaining hypertensives, 7.5% (4,201) were known but not treated and 12.3% (6,824) were under treatment but not controlled in contrast to 12.1% (4,251) and 16.8% (5,905) respectively the year before. This upward trend in controlled hypertension was present in all strata of the population.
作为芝加哥全市高血压筛查项目的一部分，1977年对177,692人进行了筛查，其中14,988人（8.4%）舒张压（BP）大于或等于95毫米汞柱，而1976年类似人群的这一比例为13.2%。高血压人群（舒张压大于或等于95毫米汞柱或目前正在服用降压药）中，只有7%（3,910人）之前未被检测出患有高血压，相比之下，前一年为11.9%（4,184人），1972年在同一社区这一比例为48.7%。相反，73.2%（40,738人）的血压得到了充分控制，相比之下，前一年为59.3%（20,897人），1972年为20.6%。在其余高血压患者中，7.5%（4,201人）已知患有高血压但未接受治疗，12.3%（6,824人）正在接受治疗但血压未得到控制，相比之下，前一年分别为12.1%（4,251人）和16.8%（5,905人）。血压得到控制的高血压患者比例呈上升趋势，这一趋势在所有人群阶层中都存在。
