Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change in daily sedentary time (h/day) | Baseline, 3 months, 6 months, 12 months | Daily sedentary time will be measured using activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days per assessment under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm to identify time in bed and non-wear periods. Sedentary time will be calculated as time classified as sitting/lying during waking wear time, expressed in hours/day. A valid day will require at least 10 hours of waking wear time. At least 4 valid days, including at least 1 weekend day, will be required. The outcome will be the mean daily sedentary time across valid days. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in sedentary time (% of waking time) | Baseline, 3 months, 6 months, 12 months. | Sedentary time as a percentage of waking wear time will be measured using activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days per assessment under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm to identify time in bed and non-wear periods. For each valid day, sedentary time (%) will be calculated as minutes classified as sitting/lying during waking wear time divided by total minutes of waking wear time, multiplied by 100. A valid day will require at least 10 hours of waking wear time. At least 4 valid days, including at least 1 weekend day, will be required. The outcome will be the mean of the daily percentages across valid days. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in daily number of breaks in sedentary time (breaks/day) | Baseline, 3 months, 6 months, 12 months. | The daily number of breaks in sedentary time will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A break will be defined as a transition from sitting/lying to standing or stepping during waking wear time. A valid day will require at least 10 hours of waking wear time. At least 4 valid days, including at least 1 weekend day, will be required. The outcome will be the mean daily number of breaks across valid days, expressed as breaks/day. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in daily number of sedentary bouts (bouts/day) | Baseline, 3 months, 6 months, 12 months. | The daily number of sedentary bouts will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A sedentary bout will be defined as a continuous period classified as sitting/lying during waking time. The outcome will be the mean number of sedentary bouts per day across valid days, expressed as bouts/day. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months |
| Secondary | Change in median sedentary bout duration (min) | Baseline, 3 months, 6 months, 12 months. | Median sedentary bout duration will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A sedentary bout will be defined as a continuous period classified as sitting/lying during waking time. For each valid day, the median duration of sedentary bouts will be calculated in minutes. The outcome will be the mean of these daily medians across valid days. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in mean sedentary bout duration (min) | Baseline, 3 months, 6 months, 12 months. | Mean sedentary bout duration will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A sedentary bout will be defined as a continuous period classified as sitting/lying during waking time. For each valid day, mean sedentary bout duration will be calculated by dividing total sedentary time by the number of sedentary bouts, expressed in minutes. The outcome will be the average of these daily means across valid days. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in maximum sedentary bout duration (min) | Baseline, 3 months, 6 months, 12 months. | Maximum sedentary bout duration will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A sedentary bout will be defined as a continuous period classified as sitting/lying during waking time. For each valid day, the duration of the longest sedentary bout will be identified in minutes. The outcome will be the mean of these daily maximum durations across valid days. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in daily time accumulated in sedentary bouts lasting ≥30 minutes (min/day) | Baseline, 3 months, 6 months, 12 months. | Daily time accumulated in sedentary bouts lasting at least 30 minutes will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A sedentary bout will be defined as a continuous period classified as sitting/lying during waking time. For each valid day, the full duration of all sedentary bouts lasting at least 30 minutes will be summed. The outcome will be the mean of these daily totals across valid days, expressed as minutes/day. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in daily time accumulated in sedentary bouts lasting ≥60 minutes (min/day) | Baseline, 3 months, 6 months, 12 months. | Daily time accumulated in sedentary bouts lasting at least 60 minutes will be derived from activPAL4 micro (PAL Technologies), worn on the anterior-medial thigh for 7 consecutive days under a 24-hour wear protocol. Data will be processed using PALanalysis with the CREA algorithm. A sedentary bout will be defined as a continuous period classified as sitting/lying during waking wear time. For each valid day, the full duration of all sedentary bouts lasting at least 60 minutes will be summed. The outcome will be the mean of these daily totals across valid days, expressed as minutes/day. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
| Secondary | Change in daily light-intensity physical activity (min/day) | Baseline, 3 months, 6 months, and 12 months | Light-intensity physical activity will be assessed using an ActiGraph wGT3X-BT worn on the non-dominant wrist for 7 consecutive days under a 24-hour wear protocol. Raw signals will be processed using GGIR in R to derive Euclidean Norm Minus One (ENMO). Light-intensity physical activity will be defined as time with ENMO values from 45 to less than 100 mg. The outcome will be the mean daily time spent in light-intensity physical activity across valid days, expressed in minutes/day. A valid day will require at least 10 hours of waking wear time. At least 4 valid days, including at least 1 weekend day, will be required. The main comparison will be change from baseline to 6 months, with additional comparisons from baseline to 3 and 12 months. |
