The primary aim of this trial is to assess the feasibility of a novel online weight gain prevention resource for new kidney transplant recipients at two London transplant clinics. A previous study conducted by the research team titled 'ExeRTiOn' provided usability feedback that led to revisions of this online resource in a purposive sample of kidney transplant recipients (n=11) and transplant multidisciplinary team members (n=6).
This current study aims to recruit a sample of new kidney transplant recipients (n=50) from two transplant sites in London. Participants will be randomized to either the 12-week kidney transplant specific novel online weight gain prevention resource (n=25) or usual care (n=25). All participants will be assessed at baseline, 12 weeks and 12 months. The primary outcome of this study is feasibility (screening, recruitment, randomization, retention, adherence to the intervention and adherence to the study visits). The research team will also assess the ability to collect measures for a definitive study (body weight, body mass index, body composition, quality of life, self-efficacy, fatigue, arterial stiffness and physical function).
A nested qualitative study will capture participant experience at two time points during this 12 month trial. At 3 months semi-structured individual interviews will be conducted in a purposive approximately 6 to 10 of the intervention participants until data saturation is achieved. These interviews will assess the experience of using the online intervention. At 6 months a purposive sample of approximately 16 participants from both groups will complete individual semi-structured interviews to assess the experiences of participating in this trial.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention Group | Experimental | This group will receive access to the 12-week kidney transplant specific weight gain prevention online resource (ExeRTiOn online resource). After the 12 weeks, they will be offered the option to continue using the website up until the completion of the study (12 months) |
|
| Control group | No Intervention | This group will not receive the online resource. They will receive the standard encouragement to follow a healthy diet and perform physical activity during routine transplant follow up appointments. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| ExeRTiOn online resource | Behavioral | This is a 12-week online resource, specifically designed for new kidney transplant recipients. It includes dietary advice, physical activity advice, and recognized behavior change techniques. The participant will be monitored by a specialist physiotherapist and will receive messages of encouragement a 6 weeks and 12 weeks. |

body mass index at each 3 study visits
| baseline, 3 months, 12 months |
| body composition over the 12 month trial | body composition will be measured at each of the 3 study visits | baseline, 3 months, 12 months |
| quality of life (self-reported) over the 12 month trial | QOL will be measured by the EQ5D questionnaire at each of the 3 study visits | baseline, 3 months, 12 months |
| self reported self-efficacy for nutrition scale over the 12 month trial | self-efficacy for nutrition will be measured via the self-efficacy scale at each of the 3 study visits. The scale has 5 statements/questions. The user selects a number from 1 to 4, with 1 being very uncertain and 4 being very certain for each of the five statements. The highest score (higher self-efficacy) is 20, the lowest score (low self-efficacy) is 5. | baseline, 3 months, 12 months |
