Objectives: General Objective: To assess the nutritional status of chronic kidney disease patients on maintenance hemodialysis at a tertiary hospital   Specific Objectives: To describe the demographic profile of chronic kidney disease patients on maintenance hemodialysis at RTR Hospital. To identify the biochemical and anthropometric parameters that will support the nutritional status of patient on hemodialysis. To identify the subjective global assessment rating of patients undergoing hemodialysis To determine the association between hemodialysis frequency to nutritional and anthropometric measurements (serum creatinine, serum albumin, total cholesterol, mid-arm circumference, triceps skinfold, and body mass index, bioimpedance) and subjective global assessment tool. Methods: A cross-sectional prospective study was conducted among forty-eight chronic kidney patients on maintenance hemodialysis at Remedios Trinidad Romualdez Hospital (RTRH). Biochemical and anthropometric measurements were taken, and patients were interviewed using a standardized data collection tool, Subjective Global Assessment (SGA). Descriptive statistics, Pearson product correlation and Spearman rho correlation were utilized. Results: Among the forty-eight chronic kidney disease patients, majority were males or 52.1%, with a mean age of 59.7 years old, mean duration of dialysis of 36.8 months, diabetes was the major leading cause of CKD, and with an adequate Kt/V or 1.32. Mean body mass index (BMI) was 22.7 kg/m2 and fifty-four (54%) of patients does not have a normal BMI. Fifty-two percent (52%) were classified as malnourished based on the criteria, of these forty-four (44%) were mildly-moderately malnourished while eight (8%) were severely malnourished. Frequency of dialysis was associated with malnutrition based on BMI and overall SGA rating Conclusions: There is an increased prevalence of malnutrition among chronic kidney disease patients. Association was noted between frequency of dialysis and body mass index and Subjective Global Assessment. This study recommends that all patients undergoing hemodialysis should have an assessment of nutritional status through biochemical, anthropometric, and Subjective Global Assessment monthly.
