Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Objective physical activity, assessed using an Actigraph accelerometer for a seven day period with a sampling epoch of 10 seconds. Time spent in moderate physical activity and vigorous physical activity will be determined based on the accelerometer counts and the ActiLife® computer software. Only days with at least 13 hours of wear time will be considered as a valid measure of daily activity. Participants will need at least five valid days, = 4 weekdays and = 1 a weekend day, for the data to be included in the data analyses. This will be assessed at the baseline (1-2 weeks after hospitalisation), 6 weeks after hospitalisation and at the follow-up (12 months after hospitalisation) 2. Physical activities during which the accelerometer cannot be worn (i.e. swimming), assessed using a non-wear time sheet | — |
Secondary
| Measure | Time frame |
|---|---|
| The following will be assessed at the baseline (1-2 weeks after hospitalisation), 6 weeks after hospitalisation and at the follow-up (12 months after hospitalisation): 1. Self-reported physical activity, assessed using the Simple Physical Activity Questionnaire (SIMPAQ) 2. Cardiorespiratory fitness, assessed using the Åstrand indirect test of maximal oxygen uptake (VO2max) 3. Autonomic function, assessed using electrocardiography (ECG) 4. Cognitive and social determinants of exercise, assessed using various validated questionnaires: 4.1. 1-item proxy for perceived fitness 4.2. 3 items regarding exercise-related self-efficacy 4.3. 16 items regarding exercise-related outcome expectancies 4.4. 1 item regarding exercise intention 4.5. 12 item SSK-Scale for self-concordance 4.6. 10 items regarding action and coping planning 4.7. 19 items regarding perceived exercise barriers 4.8. 7 items regarding exercise-related social support 5. Depression severity, assessed using: 5.1. Hamilton Rating Scale for Depression 17-item (HAMD17) 5.2. Beck Depression Inventory (BDI) 6. Self-perceived physical and psychological health, assessed using the Medical Outcomes Study 12-item Short Form Health Survey (SF-12) 7. Insomnia symptoms, assessed using the 7-item Insomnia Severity Index (ISI) 8. Cognitive function, assessed using the Test of Attentional Performance 9. Cardiovascular health risk markers: 9.1. Blood pressure, assessed using an Omron® digital blood pressure monitor 9.2. Body mass index (BMI) assessed by body weight (measured using a digital weighing scale BC-545, Tanita, USA) and body height (measured using a stadiometer) using the formula BMI = weight (kg) / (standing height (meters) squared) 9.3. Percentage body fat, assessed using bioelectrical impedance analysis using a digital weighing scale (BC-545) 9.4. Waist circumference, assessed using flexible tape at the natural waist 9.5. Total/LDL/HDL cholesterol, triglycerides and HbA1c, assessed using antecubital vein blood test | — |
