Background: Twenty-four hour ambulatory blood pressure (ABP) thresholds exist for the diagnosis of mild hypertension but not for other blood pressure (BP) thresholds used either in the diagnosis of moderate-severe hypertension or its treatment. We aimed to derive age and sex differentiated ABP equivalents for both hypertension diagnosis and treatment thresholds.

Methods: Twenty-four ABP data recorded with validated devices were collated from 11 centres across six Australian States (n=8,575) and related to clinic systolic BP (SBP) and diastolic BP (DBP) measured by health professional staff or by physician using least product regression. 

Results: Subjects were 56 years old (54% female), with body mass index 28.9 kg/m2 and clinic SBP/DBP of 142/82 mmHg. Average clinic measures were 6/3 mmHg higher than daytime ABP and 10/5 mmHg higher than 24 hour ABP. Staff-measured clinic BP was 9/7 mmHg lower than physician-measured BP. Daytime ABP equivalents were 4/3 mmHg lower at the 140/90 mmHg threshold (lower limit of grade 1 hypertension), 2/2 mmHg lower at 130/80 mmHg (upper limit with associated conditions), and 1/1 mmHg lower at 125/75 mmHg. Equivalents were 3/2 mmHg lower for females and 2-4 mmHg lower in older subjects.
