NUTRITIONAL ASSESSMENT ON ESRD PATIENTS USING SGA SCALE : A CROSS SECTIONAL STUDY

Back ground information: The aim of the study is to assess the nutritional status among ESRD patients on Haemodialysis by means of Subjective Global Assessment ( SGA) and also to know the impact of comorbid illnesses on nutritional status. Materials and methods: The study group included respondents suffering from ESRD who were patients of the Dialysis centre at Vedanta Hospitals in Guntur. The study was conducted in 50 Dialysis patients ( 36 men and 14 women).Those patients who met the study criteria were enrolled into the study. Relevant data such as demographics details, comorbid illnesses, past medical history, duration of dialysis, dialysis complications, were collected from patient proforma and a standardized SGA scale and other relevant biochemical parameters like Serum Albumin, and C reactive protein were used to evaluate the nutritional status of the patients. Statistical consideration:All the raw data was collected,entered in Excel sheet 2007 in windows 7 version. Statistical analysis methods like Pearson correlation coefficient test was used to compare variables and p value Results:The study shows that malnutition was significantly higher among those who had received HD for >3 years(p=0.008). HD patients with increase in number of comorbidities and the number of chronic medications taken had a significantly higher level of SGA (p<0.001).There is a moderate positive correlation between SGA score and CRP values(p<0.0001 the result is significant at p<0.05)A regression analysis is done for SGA and serum albumin findings showed that a negative correlation was there between SGA and serum albumin values (p value is 0.480905) the result is not significant at p<0.05. Conclusion: In our study there is a positive correlation between SGA and CRP values and a negative correlation between SGA score and serum albumin values. No significant association was found between a patients BMI and their nutritional status and also observed that socioeconomical status had a impact on nutritional status.
