Systolic and diastolic blood pressure (SBD, DBP) were measured twice at the assessment center by the use of an automated BP device (Omron 705 IT electronic blood pressure monitor; OMRON Healthcare Europe B.V. Kruisweg 577 2132 NA Hoofddorp), or manually by the use of a sphygmomanometer with an inflatable cuff in association with a stethoscope if the blood pressure device failed to measure the BP or if the largest inflatable cuff of the device did not fit around the individual's arm.²³ The participant was sitting in a chair for performing all the measures. The measures were carried out by nurses trained in performing BP measures.²⁴ Multiple available measures for one participant were averaged. The Omron 705 IT BP monitor has satisfied the Association for the Advancement of Medical Instrumentation SP10 standard and was validated by the British Hypertension Society protocol, with an overall “A” grade for both SBP and DBP.²⁵ Nevertheless, automated devices measure higher BP in comparison to manual sphygmomanometers, thus, we adjusted both SBP and DBP which were measured using the automated device using algorithms²⁶:
For SBP, we performed the following algorithm:

\begin{matrix} S B P = 3 . 3171 + 0 . 92019 \times S B P (m m H g) + 6 . 02468 \times s e x \\ (m a l e = 1; f e m a l e = 0) \end{matrix}

For DBP, we performed the following algorithm:

\begin{matrix} D B P = 14 . 5647 + 0 . 80929 \times D B P (m m H g) + 2 . 01089 \times s e x \\ (m a l e = 1; f e m a l e = 0) \end{matrix}

Systolic (SBP) and diastolic blood pressure (DBP) were measured twice at the assessment center by the use of an automated BP device (Omron 705 IT electronic blood pressure monitor; OMRON Healthcare Europe B.V. Kruisweg 577 2132 NA Hoofddorp) or manually by the use of a sphygmomanometer with an inflatable cuff in association with a stethoscope if the blood pressure device failed to measure the BP or if the largest inflatable cuff of the device did not fit around the individual’s arm.
The participant sat in a chair for all the measures. The measures were carried out by nurses trained in measuring BP. Available multiple measurements for one participant were averaged. The Omron 705 IT BP monitor satisfied the Association for the Advancement of Medical Instrumentation SP10 standard and was validated by the British Hypertension Society protocol, with an overall ‘A’ grade for both SBP and DBP^{13 (link)}. Nevertheless, automated devices measure higher BP in comparison to manual sphygmomanometers, thus, we adjusted both SBP and DBP that were measured using the automated device using the algorithms^{14 (link)}:
SBP=3.3171+0.92019×SBP (mmHg)+6.02468×sex coefficientand
DBP=14.5647+0.80929×DBP (mmHg)+2.01089×sex coefficientwhere the sex coefficient =1 for males and 0 for females.

Blood pressure was measured using the Omron 705 IT electronic blood pressure monitor (OMRON Healthcare Europe B.V. Kruisweg 577 2132 NA Hoofddorp). SBP and DBP were derived as the mean of the two recorded automated measurements (UK Biobank Fields 4079, 4080), except for 1,141 individuals who only had one recorded reading. MAP estimation was calculated using the traditional formula: MAP = DBP + 1/3(SBP-DBP). Height (Field 50) was measured using a Seca 202 device (Seca, Birmingham, UK). For individuals who reported use of anti-hypertensive medications through questionnaires in UK biobank (Fields 6177, 6153), their SBP and DBP were adjusting by adding 15 mmHg and 10 mmHg respectively to the mean recorded readings^{26 (link),37 (link)}. The ID numbers of the arterial stiffness devices used were obtained from Field 4206 in UK Biobank.

Brachial systolic and diastolic blood pressure (in millimeters of mercury) was collected at baseline (2006–2010), first follow‐up (2014–2020), and second follow‐up (2019+). The Omron 705 IT electronic blood pressure monitor (Omron, Kyoto, Japan) connected to an appropriately sized cuff (determined by measuring the participant's arm circumference) was used.⁴⁵ This was measured by registered nurses who were trained and certified to conduct the assessment. The measurement was done twice in each instance, with 1 minute between each measurement. To maximize the sample size for this analysis, data on blood pressure available at the first follow‐up (n=11 116) and second follow‐up (n=1340) were used.

Participants were asked to report their own birth weight (either in kilograms directly, or in imperial pounds and ounces). Standing height was measured using a Seca202 device. Body mass index (BMI) was defined as weight divided by height squared (m²). Waist and hip circumferences were measured with a Seca200 measuring tape using standard procedures, and waist-to-hip ratio (WHR) was the ratio of waist circumference to hip circumference.
Systolic blood pressure (SBP) and diastolic blood pressure (DBP) measurements were taken in a seated position after a few minutes of rest using an Omron 705 IT electronic blood pressure monitor. A manual sphygmometer was used if the standard automated device could not be employed. Further details of these measurements can be found in the UK Biobank online protocol (https://biobank.ndph.ox.ac.uk/showcase/showcase/docs/Bloodpressure.pdf" https://biobank.ndph.ox.ac.uk/showcase/showcase/docs/Bloodpressure.pdf). Means of SBP and DBP from two automated or two manual blood pressure measurements were calculated.

Townsend deprivation score was used as a measure of socioeconomic status and was assigned to participants based on their residential postcode at recruitment (13 ). Region was derived from assessment center location. Information on ethnicity, education, alcohol intake, smoking status, physical activity, weight change in the past year, major dietary change in the past 5 y, use of medication (antihypertensive, cholesterol-lowering, insulin, analgesic, and constipation or heartburn medication), overall health status, and the presence of a long-standing illness was self-reported through the touchscreen questionnaire. Amounts of physical activity (low, moderate, and high) were derived in accordance with the International Physical Activity Questionnaire guidelines (14 ). BMI was derived from weight using scales and standing height measured during the physical examination. Systolic and diastolic blood pressure was measured twice, with ≥1 min between measurements, using an Omron 705 IT electronic blood pressure monitor with the participant in a seated position. For the current analysis, a mean of the 2 readings was derived, with participants categorized as either “normal” (systolic ≤140 mm Hg and diastolic ≤90 mm Hg) or “hypertensive” (systolic >140 mm Hg or diastolic >90 mm Hg, or were taking antihypertensive medication).

SBP and DBP were measured by a registered nurse on the seated individual from the right brachial artery using the Omron 705 IT electronic blood pressure monitor (Omron Healthcare Europe BV, Hoofddorp, Netherlands). If the largest cuff size was too small for the participant, or if the electronic blood pressure monitor failed to produce a reading, a sphygmomanometer with an inflatable cuff was used with a stethoscope. Automated blood pressure readings were preferred when available; otherwise, manual measures were used for analyses. Two sets of systolic and diastolic blood pressure measurements were recorded in the baseline visit. The first measurement was taken at the beginning of the visit after the first interview section. The second measurement was taken at the end of the visit. Two sets of blood pressure measurements were also taken at any subsequent assessment or imaging visits after the baseline visit. The final SBP and DBP for a visit were calculated as the average of the two measurements taken during that visit. MAP was calculated from the final averaged SBP and DBP readings using the formula MAP = DBP + 1/3(SBP – DBP).¹⁹ (link) Similarly, PP was calculated as PP = SBP – DBP.²⁰ (link) Routine blood pressure measurements were recorded at the initial assessment visit, follow-up assessment visit, initial imaging visit, and follow-up imaging visit.
