End stage renal disease patients on MHD (maintained hemodialysis) have critical nutritional status. The state of nutrition is always critical for the recovery from any disease. An optimal health status assures good quality of life. The study aimed to assess the nutritional status of patients diagnosed with ESRD on maintained hemodialysis. Caloric and protein intake of patients was calculated and compared with standards. Inadequate dietary intake leads to protein energy malnutrition in patients with end stage renal disease on maintained hemodialysis. A sample of 240 patients identified with end stage renal disease (age 40-60 years) visiting outdoor patient department, department of nephrology, Sheikh Zayed Hospital and nephrology department Mayo Hospital, Lahore was selected. Sample was calculated using Yummny formula. Sample was selected through purposive sampling. Direct Nutrition assessment will be conducted through ABD. Anthropometric measurements included BMI, MAMC and TAPM (Appendices I). Biochemical tests included Creatinine, BUN, Serum albumin, total proteins and hemoglobin. Dietary intake was assessed through 24 hour diet recall and FFQ. PG-SGA form was used for screening of patients for malnutrition. The study found that the nutritional status of ESRD patients on MHD is critically poor. 82% of the subjects of the study were moderately to severely malnourished. BMI of most of the patients were normal and thus it is not a reliable parameter to assess malnutrition among critically ill patients. The dietary intake data had shown significant difference between intake and requirements of calories (kcal/day) and proteins (gm/day). The MAMC and TAPM results interpreted that lean muscle mass is depleted in more than 70% of the patients. TAPM values were significantly related with protein intake and PS-SGA score. Thus, it is a reliable parameter for the assessment of malnutrition. Descriptive

statistics, regression analysis, t-test, correlation, chi square and cross classification table was used to analyze data. Data was presented in form of graphs and tables. Statistical software SPSS version 22 was used to analyze data. Data thus obtained will serve as baseline data for improvement of nutritional status of ESRD patients. The study also validated the nutritional markers and parameters, which will be helpful in assessment of critically ill patients.
