| Measurement instrument | Baseline | 3 months | 6 months | |
| Objective measures | ||||
| PA and sedentary time | ActiGraph GTX-9 worn for 1 week at the time on their waist; setup to gather continuous data at 30 Hz epoch; blinded assessor. | X | X | X |
| Weight | Weight in kilograms measured three times with valid and reliable body scales (eg, Seca); light clothing, no shoes and empty pockets; blinded assessor. | X | X | X |
| Height | Height measured in centimetres using a stadiometer (eg, Seca); without shoes. | X | ||
| BMI | Calculated as weight in kilograms divided by the square of height in metres (kg/m2). | X | X | X |
| Waist circumference | Waist circumference measured twice (three times, if the first two measurements differ by 5 mm or more) and the mean of all recorded measurements calculated. | X | X | X |
| Resting systolic and diastolic blood pressure | Resting blood pressure measured with a digital blood pressure monitor (Omron HEM-705CP, Milton Keynes, UK) monitor after 5 min sitting still. If measured systolic blood pressure is over 139 mm Hg and/or measured diastolic blood pressure is over 89 mm Hg, two further measures will be taken and recorded, and in line with duty of care, men will be given a letter explaining the circumstances in which they had their blood pressure measured and recorded, and they will be told to consult their general practitioner. A mean will be calculated from the second and third measures.
