About this study

Official title: Prevention of Weight Gain and Impaired Glucose Metabolism Post Kidney Transplantation: A Pilot and Feasibility Study

The goal of this clinical trial is to learn whether if it is feasible to implement a study of patients receiving kidney transplantation, to learn if these patients will complete selective outcomes measurements, and to examine if a lifestyle intervention may assist with preventing weight gain compared to standard medical care. The main questions it aims to answer are:

  • Is it feasible to recruit and retain patients who have undergone kidney transplantation into a study to compare standard medical care to standard medical care plus a lifestyle intervention focused on prevention of weight gain?
  • Will participants engage in the interventions and be compliant to the components of the interventions?
  • Will there be any difference between the interventions between the interventions for the occurrence of adverse events specific to kidney transplantation?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on preventing weight gain compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on body composition compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on fasting glucose compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on fasting insulin compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on insulin sensitivity compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on physical function compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on health-related quality of life compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on changes in dietary intake compared to standard medical care alone?
  • Will there be initial effectiveness for the standard medical care plus a lifestyle intervention to have a better effect on physical activity and sedentary behavior compared to standard medical care alone?

Participants will:

  • Participants will continue with their standard medical care following kidney transplantation.
  • Participants only receiving standard medical care will also complete brief monitoring visits at week 6, 12, and 18.
  • Participants receiving the lifestyle intervention will attend weekly intervention sessions and will be recommended to modify their diet and physical activity behaviors in an effort to prevent weight gain.
  • Participants will complete outcome measurements as the start of the study and again after 6 months in the study.
  • After 6 months in the study, participants will also complete a brief intervention and answer other questions about their experience in the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard medical careOther

    Standard Care Intervention will continue to receive their regular standard clinical care during the 6-month intervention period of this study.

  • Monitoring ContactsBehavioural

    Participants will receive brief conducts (<10 minutes) remotely (telephone or video platform) with the research staff at weeks 6, 12, and 18.

  • Behavioral SessionsBehavioural

    Participants will be provided weekly individual behavioral sessions during the 6-month intervention to assist in supporting recommended changes in energy intake (diet) and physical activity.

  • DietBehavioural

    An energy balanced diet to meet energy needs that will allow for weight maintenance will be prescribed. This will be estimated using the Mifflin-St. Joer equation to estimate resting metabolic rate and for most participants we anticipate using a physical activity correction of 1.3 to account for energy needs for physical activity. This will provide the initial estimate of energy intake needs to maintain weight stability; however, the prescribed level of energy intake will be adjusted at 4-week intervals across the intervention based on the observed changes in weight, eating behaviors, and physical activity patterns in an effort to prevent excessive weight gain. Within the context of this level of energy intake, we will prescribe a diet that is consistent with the dietary recommendations of the National Kidney Foundation.

  • Physical ActivityBehavioural

    Physical activity will be recommended in the form of aerobic types of activity such as brisk walking and will progress in 4-week intervals from an initial amount of 50 minutes per week to 150 minutes per week across the initial 6 months of the intervention. Moderate intensity will be prescribed, and will be anchored using RPE (rating of perceived exertion) to allow intensity to be self-regulated according to the participant's capacity. Physical activity will be prescribed in the form of walking; however, the participant will be permitted to engage in other forms of physical activity that meet the recommended dose and intensity.
