Automated office blood pressure (AOBP) measurement, attended or unattended, eliminates the white coat effect (WCE) showing a strong association with awake ambulatory blood pressure (ABP). This study examined the difference in AOBP readings, with and without 5 minutes of rest prior to three readings recorded at 1‐min intervals. Cross‐sectional data from 100 randomized selected hypertensives, 61 men and 39 women, with a mean age of 52.2 ± 10.8 years, 82% treated, were analyzed. The mean systolic AOBP values without preceding rest were 127.0 ± 18.2 mm Hg, and the mean systolic AOBP values with 5 minutes of preceding rest were 125.7 ± 17.9 mm Hg (P = .05). A significant order effect was observed for the mean systolic BP values when AOBP without 5 minutes of preceding rest was performed as the first measurement (130.0 ± 17.7 vs 126.5 ± 16.2, P = .008). When we used a target systolic AOBP ≥ 130 mm Hg, awake ABP yielded lower readings, while at a target systolic AOBP value of
