Nutrition Status of Patients During Hospitalization,Tehran,Iran

Abstract

Background: We assessed the nutrition status of patients on admission and monitored changes during hospitalization at Shariatri Educational Hospital, Tehran, Iran. Methods: One hundred fifty-six randomly selected patients from 9 different wards were assessed. Body mass index (BMI) and body composition (based on bioelectrical impedance) were measured on admission and discharge. A questionnaire was also completed to evaluate general physical, psychological, and living status of the patients. Medical records were audited to identify when nutrition consultation, nutrition support, and nutrition-related laboratory factors (serum levels of total lymphocyte count [TLC] and albumin) were ordered. Frequency and paired t-test were used to analyze data. Results: Undernutrition (BMI <18.5 kg/m²) was present in 5.7% of the patients on admission, and severe undernutrition (BMI <16 kg/m²) existed in 0.6%. When discharged, 11% of patients were undernourished, and the prevalence of severe undernutrition increased to 1.3%. Average body weight and BMI decreased significantly during hospitalization (p < .001). Body composition analysis showed a significant reduction in body protein mass (p < .001). During hospitalization, body water percentile decreased and body fat percentile increased but not significantly. Only 1 patient was supported with parenteral nutrition (PN) and 1 with enteral nutrition. Orders for nutrition consultation were present in 1.9%, TLC levels in 10.8%, and serum albumin levels in 7% of the patient medical records surveyed. Conclusions: Undernutrition increased in patients during hospitalization. According to the low rate of nutrition-related orders, one potential cause of worsening nutrition status may be inadequate medical staff awareness about the importance of nutrition in hospitalized patients.
