During our participants’ first ‘baseline’ visit at one of 22 centres across the UK, we carried out physical assessments.

The information allows researchers to look at how health conditions impact participants’ memory, activity, senses and other bodily functions.

Physical measurements data at a glance

General physical measures

Participants’ height, weight, waist and hip circumference, lung capacity, body composition (muscle and fat mass), hand grip strength, heel bone density and blood pressure.

  • Current availability
    • 500,000 participants
    • Repeat measures were taken for 20,000 participants who attended a second baseline assessment, as well as for 90,000 participants who attended an imaging assessment

Arterial stiffness

Participants’ arterial pulse-wave velocity, which is the speed of the blood pressure pulse as it propagates through the circulatory system.

  • Current availability
    • 200,000 participants
    • Repeat measures were taken for 20,000 participants who attended a second baseline assessment, as well as for 90,000 participants who attended an imaging assessment

Vision

Participants’ visual acuity, autorefraction (a measure of how light changes as it comes into the eye), inner-eye pressure and eye-surgery complications.

  • Current availability
    • 150,000 participants
    • Repeat measures were taken for 20,000 participants who attended a second baseline assessment, as well as for 3,000 participants who attended a repeat imaging assessment

Hearing

Participants’ ability to identify spoken words when background noise is present.

  • Current availability
    • 200,000 participants
    • Repeat measures were taken for 20,000 participants who attended a second baseline assessment, as well as for 90,000 participants who attended an imaging assessment

Memory

During baseline assessment, participants completed a series of touchscreen tests for memory. Most of these were similar to the tests participants completed for the cognitive function questionnaire.

  • Current availability
    • 500,000 participants
    • Repeat measures were taken for 20,000 participants who attended a second baseline assessment, as well as for 90,000 participants who attended an imaging assessment

Fitness

Participants’ heart rate measured with a 4-lead electrocardiogram while they cycled for six minutes on a stationary bike.

  • Current availability
    • 90,000 participants

Activity monitor data

Participants wore an activity monitor for one week.

  • Current availability
    • 90,000 participants
    • 250,000 participants with repeat measures

12-lead electrocardiogram (ECG) data

Electrical activity of participants’ heart at rest.

  • Current availability
    • 90,000 participants
    • 3,000 participants with repeat measures (collected within two years of the first)

Physical measurements data research stories

Read a selection of stories about how healthcare is being changed by discoveries made with physical measurements.

Activity monitor data from more than 25,000 UK Biobank participants reveals the potential benefits of activity bursts in those who are normally inactive.

Algorithm that identifies heart-muscle thickening from routine heart activity test has been created with data from more than 37,500 UK Biobank participants.

Algorithm that analyses smartwatch data detects minute movement changes many years before symptoms appear.

Physical activity doesn’t need to be spread out over the week – ‘weekend warriors’ seem to get same health benefits.
