Background and Purpose— To assess the prevalence of premorbid undernutrition its impact on outcomes 1 month after stroke. Methods— The study recruited from consecutive stroke admissions during a 10-month period. Premorbid nutritional status (using subjective global assessment [SGA]), functioning (modified Rankin scale [MRS]), severity (National Institutes Health Stroke Scale [NIHSS] score) were assessed at admission. associations between status, poor outcome (defined as MRS ≥3), mortality examined before adjustment for confounding variables, including age, gender, risk factors, severity, admission serum albumin. Results— Thirty 185 patients having Significant unadjusted observed (odds ratio [OR], 3.4; 95% CI, 1.3 to 8.7; P =0.01), (OR, 3.1, 7.7; =0.02) month. NIHSS, also significantly associated with outcomes. After these effect size remained important but not significant (poor outcome: OR, 2.4; 0.7 9.0, =0.18; mortality: 3.2; 1.0 10.4, =0.05). Conclusions— undernutrition, using SGA, appears be an independent predictor outcome. prevention strategies should target in population improve
