Objective The Subjective Global Assessment (SGA) is a validated tool for identifying nutritional status in patients receiving maintenance dialysis (MHD), but it is not without limitations. Current research identifies additional clinical characteristics such as phase angle (PhA) associated with SGA. This study aimed to assess the overall correlation between PhA and SGA; associations between PhA and SGA by body mass index (BMI), and to identify clinical characteristics associated with SGA. Design and Methods This is a secondary analysis of the Rutgers Nutrition 95% CI= 1.06, 1.19) of being moderately malnourished than well-nourished. In this fully adjusted model, increasing FFM (OR= 0.95, 95% CI=0.91, 0.99) and FM (OR = 0.92, 95% CI= 0.87, 0.97) by 1 kg was also associated with a 5% and 8% lower odds of being moderately malnourished, respectively. Conclusion PhA and SGA were significantly associated only among patients classified as obese. PhA, WC, FM, and FFM were identified as potential clinical determinants of SGA. Patients receiving MHD and who have obesity may benefit from utilizing SGA along with WC, PhA, FM, and FFM to assess nutritional status.
