[Nutritional status evaluation in maintenance hemodialysis patients]

Area of Science:

• Nephrology
• Clinical Nutrition
• Body Composition Analysis

Background:

• Protein-calorie malnutrition is a frequent complication and predictor of mortality in patients with end-stage renal disease (ESRD) undergoing maintenance dialysis.
• Regular assessment of nutritional status is crucial for early detection and management of malnutrition in dialysis patients.

Purpose of the Study:

• To evaluate the nutritional status of hemodialysis patients.
• To identify potential risk factors associated with malnutrition in this population.

Main Methods:

• A cross-sectional study involving 149 hemodialysis patients.
• Nutritional status was assessed using anthropometry (height, body weight, mid-arm circumference, triceps skin-fold thickness), biochemical tests (serum albumin, creatinine, hemoglobin, etc.), and bioelectrical impedance analysis (BIA) for body composition.
• Statistical analyses included t-tests for comparisons and Pearson correlation for relationships.

Main Results:

• Male patients exhibited higher muscle mass and lower fat mass compared to females.
• Advancing age correlated positively with BMI but inversely with body cell mass and muscle mass.
• Patients with diabetes, heart failure, or lower hemoglobin levels showed significantly worse nutritional status indicators, including reduced body cell mass, muscle mass, and serum albumin.

Conclusions:

• In hemodialysis patients, factors such as increasing age, diabetes, heart failure, and decreasing hemoglobin levels are associated with poorer nutritional status.
• Further research is warranted to investigate whether managing comorbidities like heart disease and anemia can improve nutritional status in this patient group.
