Plain English summary of protocol
Background and study aims
In 2017, the International Society of Hypertension (ISH) conducted a global blood pressure screening survey across about 100 countries, collecting data from over 1.2 million participants. Following the success of the 2017 campaign, in 2018, ISH proposes to conduct a second global blood pressure (BP) survey of volunteer adults (aged 18 and over) who ideally have not had their BPs measured for at least a year before BP screening.
Who can participate?
Volunteers aged 18 and over
What does the study involve?
Basic demographic and clinical information as well as BP measurements are collected by health profession volunteers throughout May 2018. Sitting blood pressure is measured three times according to standardised specified methods. Participants whose BP readings are consistent with the current definition of hypertension are provided with written dietary and lifestyle advice. They are also provided with a referral to receive medications and/or follow up support, according to local facilities.
What are the possible benefits and risks of participating?
Participants will benefit from individual and immediate feedback on their blood pressure status and, where blood pressure is above targets, they are given lifestyle advice and a card with their blood pressure readings and the suggestion to confirm the readings with their GPs at the earliest possible opportunity. There are no serious risks to the participants. Blood pressure cuff inflation may cause minor discomfort. People asked to see their GP at some point might develop concerns or anxiety about this – the MMM team will provide written explanations of the lack of risk involved in being asked to see the GP due to a potentially raised blood pressure.

| Scientific title | UK contribution to May Measurement Month, a global strategy to measure blood pressure in 25M people across the world |
| Study acronym | MMM18 |
| Study objectives | To screen at least 1 million people aged ≥ 18 years who ideally have not had their BPs measured for at least a year prior to the current BP screening. |

| Health condition(s) or problem(s) studied | High blood pressure (hypertension) |
| Intervention | The survey will be conducted in approximately 100 countries each incorporating a variable number of screening sites. Basic demographic and clinical information as well as BP measurements will be collected by health profession volunteers throughout May 2018. Sitting blood pressure will be measured in triplicate according to standardised specified methods. The data will be anonymised, coded and transferred electronically (through a purpose-designed application or using an Excel spreadsheet) to a central AWS DynamoDB database. Screenees whose BP readings are consistent with the current definition of hypertension will be provided with written dietary and lifestyle advice. Participants will also be provided with a referral to receive medications and/or follow up support, according to local facilities. |
| Intervention type | Behavioural |
| Primary outcome measure(s) |
Systolic and diastolic blood pressures and pulse rate measured up to three times in the sitting position after 5 min rest using automated blood pressure monitors or, if unavailable, ordinary sphygmomanometer. Measurements taken once at baseline. |
| Key secondary outcome measure(s) |
Measure of body mass index (in kg/m2) taken as weight in kg or lb (converted in kg) and height in cm or ft and inch (and converted in cm). Measures will be either self-reported or measured with a stadiometer and electronic weighing scales. Measurements taken once at baseline. |
