Study Details

Brief summary:

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.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Receiving a kidney transplant within the prior 3-5 months, with the transplant received from a deceased donor or living donor. NOTE: The patient will be eligible for randomization at 3 months following the kidney transplant, or at a subsequent time once clearance from the kidney transplant physician is given, provided that the time does not exceed 5 months following the kidney transplant.
  • Both males and females of all race/ethnic groups are eligible for participation in this study.
  • >=18 years of age.
  • Body mass index (BMI) >22 kg/m2. There is no maximal BMI provided that the weight does not exceed the weight allowance of the dual-energy x-ray absorptiometer (DXA) that is used to assess body composition (maximal weight for the DXA is 350 pounds).
  • Ability to provide informed consent prior to participation in this study.
  • Ability to provide clearance from their kidney transplant physician to engage in the diet and physical activity components of the proposed intervention and to safely complete the proposed outcome measures.
  • Ability to walk for exercise.

Exclusion Criteria:

  • Females who are pregnant, breastfeeding, or reporting a planned pregnancy during the study period. Female participants of childbearing age who are not currently taking contraceptive medication, are not post-menopausal, or have not been surgically sterilized will need to agree to use a double barrier method of contraception.
  • History of bariatric surgery.
  • Currently prescribed an anti-obesity medication.
  • Report current medical condition or treatment for a medical condition that could affect body weight. These may include the following: diabetes mellitus; hyperthyroidism; inadequately controlled hypothyroidism; chronic liver disease; cancer; gastrointestinal disorders including ulcerative colitis, Crohn's disease, or malabsorption syndromes; etc.
  • Current congestive heart failure, angina, uncontrolled arrhythmia, symptoms indicative of an increased acute risk for a cardiovascular event, prior myocardial infarction, coronary artery bypass grafting or angioplasty, conditions requiring chronic anticoagulation (i.e., recent or recurrent DVT).
  • Resting systolic blood pressure of >=160 mmHg or resting diastolic blood pressure of >=100 mmHg or not on a stable medical treatment to control hypertension (stable dose is defined as the same dose and type of medication for a period of at least 6 months).
  • Eating disorders that would contraindicate modifying eating or physical activity behaviors.
  • Alcohol or substance abuse.
  • Currently treated for psychological issues (i.e., depression, bipolar disorder, etc.) that is accompanied by the following: 1) not on a stable dose of medications for treatment within the previous 12 months, or 2) hospitalized for depression within the previous 5 years.
  • Report plans to relocate to a location not accessible to the study site or having employment, personal, or travel commitments that prohibit attendance at scheduled intervention sessions or assessments.

Interventions and Outcome Measures

Arms

active comparator: Standard Medical Care

Standard Care Intervention will continue to receive their regular standard clinical care during the 6-month intervention period of this study and will also receive brief conducts (<10 minutes) from the research staff at weeks 6, 12, and 18.

experimental: Standard Medical Care plus Lifestyle Intervention

Standard Medical Care plus Lifestyle Intervention will continue to receive their regular standard clinical care and a behavioral intervention focused on dietary modification and physical activity for body weight regulation.

Interventions

Standard medical care

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

Monitoring Contacts

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

Behavioral Sessions

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.

Diet

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 Activity

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.
