Nutritional status of patients according to the stage of chronic renal failure

Abstract

Introduction. In Burkina Faso, chronic kidney disease (CKD) is a major public health problem due to its increasing prevalence, severity and the high cost of treatment. Aim. The aim of this study was to describe nutritional status of subjects diagnosed with severe and moderate stages of chronic renal insufficiency, followed in nephrology consultation at the Yalgado Ouedraogo University Hospital Center (YO-UHC) of Ouagadougou. Methods. A descriptive cross-sectional study conducted over a period of eight months and included 75 patients in total. The social-demographic parameters were determined on the basis of the patients' declaration and the use of their medical records. Biological parameters were collected from the results of laboratory examinations performed by each patient. The nutritional status of the patients was assessed by the anthropometric method. Finally, all patients were asked about their dietary habits and lifestyle using the 24-hour recall method. Results. Our results revealed a male predominance, out of the total number of patients included. The percentage of men and women was 54.70% and 45.30% respectively with a sex (male/female) ratio of 1.20. The average of Body Mass Index was 24.79 Kg/m2. The percentage of overweight and obesity of women was 64.71% compared to 26.83% for men. The proportion of women with severe chronic kidney disease (58.82%) was twice as high as that of men (29.27%), (P<0.05). The average waist circumference of the subjects aged 30-39 years was significantly lower than that of the subjects aged 60-85 years. So, average hip circumference was 93.77 cm, with a significant difference according to sex (P<0.05). The prevalence of hyperglycaemia and diabetes increased with age. Hyperglycaemia in the 40-49 age group was increased significantly from 16.67% to 26.67% in the 70-85 age group (P<0.05). Diabetes in the 50-59 age group was 10% and doubled in the 70-85 age group (P<0.05). A percentage of 67.99% of the patients had a history of hypertension in either first-degree relatives or collaterals. The highest proportion was found in the hypertensive collaterals (37.33%; P=0.059). This study revealed a low level of physical activity among all patients. Only 38.67% of the patients practiced regular physical activity. There was no significant association between the level of physical activity and the stage of renal failure. Conclusion. Knowledge of nutritional status is a crucial part of better nutritional management of CKD patients. Finally, previous studies on the dietary habits of patients suffering from CKD will allow a better understanding of their nutritional status for a better management according to the stage of progression of the disease.
