Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Objectively measured physical activity using an Axivity AX3 3-Axis Logging Accelerometer®, defined as average acceleration (m/s2) over a 12 -week observation period. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Objectively measured dietary behaviour: serum carotenoid levels 2. Cardiovascular risk factors: objectively measured total-, high density lipoprotein-, and low-density lipoprotein-cholesterol, triglycerides and fructosamine; self-reported weight, smoking status, alcohol consumption, physical activity and dietary behaviour 3. Current self-reported medication and healthcare usage 4. Perceived risk: comparative and absolute perception of risk 5. Cognitive evaluation of provision of cardiovascular risk scores: participant’s acceptability and understanding, of the risk scores and accuracy of their risk perception 6. Psychological outcomes: anxiety associated with testing, fatalism, depression, stress and mood 7.
