Background: Disease-related malnutrition is associated with adverse outcomes such as increased rates of morbidity and mortality, prolonged hospital stay, and extra costs of health care. This study was conducted to assess nutritional status among patients and to determine the risk factors for malnutrition in Iran university hospitals. Methods: Persian Nutritional Survey In Hospitals (PNSI) was a cross-sectional study that conducted in 20 university hospitals across Iran. All the patients with age range of 18 to 65 years, who were admitted or discharged, were assessed by subjective global assessment (SGA). Results: In total, 2306 patients were evaluated for malnutrition. Mean values of age and body mass index were 44.7±14 years and 25.2±6 kg/m2, respectively. Malnutrition (SGA-B & C) was identified in 23.9% of the patients, 26.2% and 21% of whom were among the admitted and discharged patients, respectively. The prevalence of malnutrition was higher in burns (78%) and heart surgery (58%) patients. Malnutrition was not associated with age (P=0.1). Multivariate analysis presented male gender (OR=1.023, P<0.001), malignant disease (OR=1.409, P<0.001), length of hospital stay (OR=1.206, P<0.001), and polypharmacy (OR=1.066, P<0.001) as independent risk factors for malnutrition.Conclusion: One out of four patients in the studied university hospitals was suffering from malnutrition; thus, appropriate measures should be taken to ameliorate this condition. Male gender, malignant disease, length of hospital stay, and polypharmacy were identified as independent risk factors for malnutrition.

This study was conducted to assess nutritional status among patients and to determine the risk factors for malnutrition in Iran university f. Methods Persian Nutritional Survey In Hospitals (PNSI) was a cross-sectional study that conducted in 20 university hospitals across Iran. All the patients with age range of 18 to 65 years, who were admitted or discharged, were assessed by subjective global assessment (SGA). Results In total, 2109 patients were evaluated for malnutrition. Mean values of age and body mass index were 44.68 ± 14.65 years and 25.44 ± 6.25 kg/m2, respectively. Malnutrition (SGA-B & C) was identified in 23.92% of the patients, 26.23 and 21% of whom were among the admitted and discharged patients, respectively. The highest prevalence of malnutrition was in burns (77.70%) and heart surgery (57.84%) patients. Multivariate analysis presented male gender (OR = 1.02, P < 0.00), malignant disease (OR = 1.40, P < 0.00), length of hospital stay (OR = 1.20, P < 0.00), and polypharmacy (OR = 1.06, P < 0.00) as independent risk factors for malnutrition. Malnutrition was not associated with age (P = 0.10). Conclusion This study provides an overall and comprehensive illustration of hospital malnutrition in Iran university hospitals, finding that one out of four patients were malnourished; thus, appropriate consideration and measures should be taken to this issue.
