Assessment of Nutritional Status in Kidney Transplant Patients at Haukeland University Hospital
Not peer reviewed

Background and aims: Chronic kidney disease (CKD) may give implications of nutritional status, and studies suggest that patients with CKD have increased risk of malnutrition and nutrition related conditions such as sarcopenia. Not all implications related to kidney disease will disappear after kidney transplantation, and side effects from polypharmacy may give additional implications in these patients. Nutritional status in kidney transplant patients has not been reviewed in many studies. The aim of this study was to assess nutritional status in kidney transplant patients and identify which nutritional challenges are present after kidney transplantation. Methods: A cross-sectional observational study was conducted which included kidney transplant recipients from the outpatients’ clinic at the department of nephrology at HUS September 2016 - January 2017. Information about disease history, lifestyle, health condition, anthropometric measurements, functional measurements, dietary intake, and chemical clinical analysis results were obtained. Results: The study population consisted of 72 patients (71% male) with the median age of 59.5 years (IQR 49.0, 66.8). Mean BMI was 26.7 kg/m2 (SD ± 4.5), with 65% of the study population being overweight or obese. Central obesity was identified in 50% of the study population. Nutritional risk was identified in 7-10% of the patients, depending on which screening tool applied. Sarcopenia was identified in 31% of the study population diagnosed by reduced muscle strength and muscle mass, measured by HGS and BIA, respectively. Conclusion: The nutritional challenges in kidney transplant recipients are presented as overnutrition in term of overweight and obesity rather than undernutrition in this study population. Assessment of body composition and muscle strength revealed a prominent proportion of sarcopenic patients, in all BMI-categories. Results suggest that nutritional care concerning overnutrition and sarcopenia may be necessary in this patient group, and that measurement of weight and height for the calculation of BMI may not be sufficient in assessment of nutritional status and body composition.
