The Tecumseh Blood Pressure Study

Abstract
• In Tecumseh, Mich, we obtained blood pressure (BP) selfdetermination data in 608 healthy adults (327 men, 281 women; average age, 32.6 ± 3.5 years) representing a wide range of educational backgrounds. The average (±SD) home BP (average 12.7 readings over 1 week) was 120.7/74.8±10.4/8.6 mm Hg for men and 110.9/69.9±10.1/7.7 for women. One hundred thirty-three subjects remeasured their home BP 1 year later and a strong correlation between the two readings was obtained (r=.70). Large-scale BP self-determination is feasible. Based on the BP distribution in Tecumseh, the upper limit of normalcy for home BP (2 SDs above the mean) is 142/92 mm Hg for men and 131/85 mm Hg for women. (Arch Intern Med. 1990;150:1209-1213)
