To evaluate the clinical usefulness of the subjective assessments of nutritional status (Mini-Nutritional Assessment [MNA] and scored patient-generated subjective global assessment [PG-SGA]), compared with the objective (hematological, biochemical, and anthropometric) assessments, and to identify the correlation between the MNA and the scored PG-SGA in elderly patients with stroke. Thirty-five stroke patients, aged 60 to 89 years old, participated in our study. The MNA, the scored PG-SGA and objective factors were evaluated. The objective malnutrition state was defined based on laboratory outcomes. According to the MNA and the scored PG-SGA classifications, total patients were respectively divided into three groups; well-nourished (W), at risk of malnutrition (R), and malnourished (M), and into four groups; normally nourished (A), suspected or mildly malnourished (B), moderately malnourished (C), and severely malnourished (D). Mean age and body mass index of subjects were 70.6 years and 22.2 kg/m(2), respectively. Twenty-six (74.3%) patients were identified to be at an objectively malnourished state. In MNA, 3 (8.6%) patients were classified as group W, 13 (37.1%) as R, and 19 (54.3%) as M. Total MNA scores and three categorization had mild correlation with objective grouping (r=0.383, r=0.350, p<0.05, respectively). Restructuring into two groups by combining group R and M made strong correlation (r=0.520, p<0.01). On the basis of scored PG-SGA, 6 (17.1%) patients were sorted as group A, 10 (28.6%) as B, 15 (42.9%) as C, and 4 (11.4%) as D, respectively. Total scores and the grouping into four indicated meaningful correlation with the objective distinction (r=-0.403, p<0.05, r=0.449, p<0.01, respectively). There was a significant correlation between the MNA scores and the PG-SGA scores (r=-0.651, p<0.01). It is proposed that the MNA and the scored PG-SGA would be useful in screening malnourished elderly patients with stroke.
