Background  The value of subjective global assessment (SGA) as nutritional assessor of protein-energy wasting (PEW SGA ) in chronic kidney disease (CKD) patients depends on its mortality predictive capacity. We investigated associations of PEW SGA  with markers of nutritional status and all-cause mortality in CKD patients.    Methods  In 1031 (732 CKD1-5 non-dialysis and 299 dialysis) patients, SGA and body (BMI), lean (LBMI) and fat (FBMI) body mass indices, % handgrip strength (% HGS), serum albumin, and high sensitivity C-reactive protein (hsCRP) were examined at baseline. The five-year all-cause mortality predictive strength of baseline PEW SGA  and during follow-up were investigated.    Results  PEW SGA  was present in 2% of CKD1-2, 16% of CKD3-4, 31% of CKD5 non-dialysis and 44% of dialysis patients. Patients with PEW SGA  (n = 320; 31%) had higher hsCRP and lower BMI, LBMI, FBMI, %HGS and serum albumin. But, using receiver operating characteristics-derived cutoffs, these markers could not classify (by kappa statistic) or explain variations of (by multinomial logistic regression analysis) presence of PEW SGA . In generalized linear models, SGA independently predicted mortality after adjustments of multiple confounders (RR: 1.17; 95% CI: 1.11–1.23). Among 323 CKD5 patients who were re-assessed after median 12.6 months, 222 (69%) remained well-nourished, 37 (11%) developed PEW SGA  de novo, 40 (12%) improved while 24 (8%) remained with PEW SGA . The latter independently predicted mortality (RR: 1.29; 95% CI: 1.13–1.46).    Conclusions  SGA, a valid assessor of nutritional status, is an independent predictor of all-cause mortality both in CKD non-dialysis and dialysis patients that outperforms non-composite nutritional markers as prognosticator.
