Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dietary management of CKD patients proved important to postpone dialysis. Long-term compliance to protein-restricted diets was discussed. Psychological aspects involved in certain dietary behaviour have never been studied.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The interest in dietary management resurged, since the high prevalence of revealed a major impact not only on morbidity, mortality, social activities and patients' quality of life, but also on health budget.

Although protein-restricted diets are used for more than a century in patients with advanced Chronic Kidney Disease (CKD), their efficacy and safety is still debatable. Enough evidence has being accumulated on their role in postponing dialysis initiation in compliant patients. Consequently, the long-term compliance to the diet is discussed. Psychological aspects of compliant patients are certainly involved. Identification of certain psychological predictors of dietary compliance could help to select the patients who are more likely to be compliant and therefore to benefit from such an intervention. Moreover, short-term or long-term psychological intervention addressing these factors could increase patient long-term compliance.

Accordingly, we are aiming to evaluate psychological characteristics of Chronic Kidney Disease patients in relation with their compliance to protein-restricted regimens.
