NCT05927337

Brief Summary

In the study Cognitive-Behavioral Therapy (CBT) for Managing Obesity in People with Chronic Kidney Disease (CKD) the investigators will test whether CBT programme is effective for weight loss and weight maintenance after the treatment programme in patients with obesity, chronic kidney disease and proteinuria. The investigators will test whether subjects randomised to the intervention group and receiving cognitive behavioural therapy can achieve greater weight loss and proteinuria reduction in chronic kidney disease than subjects randomised to the control group and not receiving cognitive behavioural therapy. Both groups of subjects will be counselled by a dietician to improve their diet and reduce excess weight and to kinesiologist for advice on physical activity.

Study Arms (2)

Cognitive Behavioral Therapy for managing Obesity

EXPERIMENTAL

Participants will be enrolled in a 4-month programme of cognitive behavioural therapy for obesity management. The programme is described in more detail in the annex. The programme will consist of 12 individual sessions, with weekly sessions for the first eight weeks and bi-monthly sessions for the following eight weeks. Treatment as usual: participants will receive three sessions with a dietician to receive basic information on appropriate diet, energy deficit and nutrition plan and three sessions with a kinesiologist to receive advice on physical activity.

Behavioral: Cognitive Behavioral Therapy (CBT) for managing Obesity

Control group

NO INTERVENTION

Treatment as usual: participants will receive three sessions with a dietician to receive basic information on appropriate diet, energy deficit and nutrition plan and three sessions with a kinesiologist to receive advice on physical activity.

Interventions

Patients included in the intervention group will be treated with a tailored cognitive behavioural therapy programme for obesity management. The programme is designed and adapted from the Individualised Cognitive Behavioural Therapy for Obesity Management programme (Dalle Grave et al., 2018), which is divided into six content modules aimed at weight loss and weight maintenance. For the purpose of the research, an abbreviated programme will be designed and used, and the content modules will remain the same as in the original version of the programme.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients with chronic kidney disease (proteinuric form) from stage 2 to stage 4 (oGF 60 to 15 ml/min/1.73m2);
  • with or without associated type 2 diabetes mellitus;
  • with a body mass index greater than 30 kg/m2 or waist circumference greater than 94 cm (men) or 80 cm (women);
  • who have an estimated daily proteinuria exceeding 200 mg protein per g urinary creatinine.

You may not qualify if:

  • acute psychiatric illness or chronic, poorly managed psychiatric illness;
  • dementia;
  • bioimpedance findings of low lean body mass index below that expected for age and sex (or presence of any other sarcopenic obesity criteria);
  • active chronic inflammatory disease (e.g. active vasculitis, SLE, rheumatoid arthritis) or active cancer;
  • active nephrotic syndrome;
  • NYHA grade 3 or 4 heart failure;
  • spontaneous weight loss of 5% or more in the last 6-month period;
  • receiving induction immunosuppression therapy for autoimmune renal disease (receiving maintenance immunosuppression therapy for no retention);
  • any other clinical factor that puts the patient at risk with regard to metabolic stability and daily energy expenditure.
