title: [Nutritional status of elderly surgical patients].
abstract: The aim of this study was to assess nutritional status of aged surgical patients, to determine the prevalence of malnutrition and factors associated with it.
  
  
  METHODS
  A total of 156 patients aged 45 years and more, treated at the Departments of Surgery and Urology of Kaunas 2nd Clinical Hospital, were enrolled in the study. Elderly group (aged 65 years and more) consisted of 99 patients, and middle-aged group (45 to 64 years old) of 57 patients. The following anthropometric measurements were performed: weight, height, mid-arm circumference; hemoglobin, serum albumin level, and total lymphocyte count were determined. Standard assessment scales included Instrumental Activities of Daily Living, Geriatric Depression Scale, and Mini Mental State Exam. Statistical analysis was performed with the help of SPSS 12.0.
  
  
  RESULTS
  Malnutrition was diagnosed in 53.5% of older patients and in 15.8% of middle-aged patients (P<0.05). Obesity was diagnosed in 32.3% of elderly patients and in 40.4% of middle-aged patients (P<0.05). Among men, obese patients made up 20%, among women - 54.4% (P<0.05). Malnutrition was more prevalent among elderly patients who underwent urgent operations than in patients who underwent planned operations (69.6% and 34.1%, respectively; P<0.05) and among elderly patients with impaired cognitive functions than among those without impaired cognitive functions (in 100% of patients with medium impaired cognitive function, in 59.3% of patients with mild impaired cognitive function, and in 44.4% of patients with unimpaired cognitive function, P<0.05). Malnourished elderly patients had lower functional level than the remaining (IADL score of 3.97 and 4.75 for men, 5.38 and 6.89 for women, respectively; P<0.05). The prevalence of malnutrition did not differ significantly in the groups of older patients with depression, probable depression and not depressed patients - 75.0%, 57.7%, and 46.7%, respectively (P>0.05).
  
  
  CONCLUSIONS
  Malnutrition was diagnosed more frequently in elderly surgical patients than in middle-aged patients. Obesity was more common in women than in men. The prevalence of obesity was not associated with age. Malnutrition in elderly surgical patients was associated with poor functional status, impaired cognitive function, and urgent operation.
