RELATIONSHIP BETWEEN BODY MASS INDEX AND CREATININE AND UREUM LEVELS IN CHRONIC KIDNEY DISEASE PATIENTS UNDERGOING HEMODIALYSIS AT SANJIWANI HOSPITAL

Abstrak

Chronic kidney disease (CKD) is a condition characterized by sustained changes in kidney structure and function lasting for more than three months. The hemodialysis (HD) procedure can impact the nutritional status of CKD patients through increased degradation of body proteins. This degradation is reflected in elevated blood levels of creatinine and urea. The aim of this study was to analyze the relationship between body mass index (BMI) and serum creatinine and urea levels in CKD patients undergoing HD at Sanjiwani Hospital, Gianyar. This was an analytical observational study with a cross-sectional design, involving 95 CKD patients undergoing HD who met the inclusion and exclusion criteria. The study population was predominantly male (63.2%), with a median age of 50 years (range 21–63 years). The average BMI was 24.15 ± 4.56 kg/m², the mean serum creatinine level was 9.67 ± 2.83 mg/dL, and the mean serum urea level was 126.08 ± 35.50 mg/dL. Pearson correlation analysis revealed a significant, but weak, positive correlation between BMI and serum creatinine levels (r = 0.246, p = 0.016). In contrast, the correlation between BMI and serum urea levels was not significant (r = 0.147, p = 0.155). Based on these results, we conclude that while there is no significant relationship between BMI and serum urea levels, there is a weak, significant relationship between BMI and serum creatinine levels, indicating that higher BMI may be associated with increased serum creatinine levels in HD patients.
