Recognition of malnutrition in an early phase might be beneficial for patients and screening for malnutrition in an outpatient setting might, therefore, be worthwhile.Aim: To determine the extent of malnutrition in outpatients with pulmonary diseases using different methods.Methods: All patients visiting our outpatient department of pulmonary diseases for the first time (period Oct. 2010 - Febr. 2011) were screened for malnutrition. Different methods were used to screen for malnutrition: body mass index (bmi), Short Nutritional Assessment Questionnaire (SNAQ), and a fat free mass measurement (FFM; bio-impedance by Bodystat® 1500).Results: Data of 121 outpatients (mean age 59, 49% male, 29% COPD) were analysed. Obesity (bmi > 30) was found in 26% of patients and underweight (bmi < 21 in COPD, and respectively <18.5 or <20 in non-COPD, aged ≤65 or >65 yrs) was found in 7 patients. The SNAQ score detected 9 and 3 patients being severely or moderately malnourished. FFM revealed 17 patients (14%) with malnutrition. Combining SNAQ and bmi resulted in detection of 17 malnourished patients. However, different patients are detected (Table 1).View this table:Table 1. Malnutrition: FFM vs. SNAQ + bmiA low FFM was found more often in patients with COPD (23%) and in females (21%).Conclusion: This study revealed malnutrition in 6 to 14% of outpatients with pulmonary diseases. Measurement of bmi only seems to underestimate nutritional problems. The discrepancies in detecting different patients emphasise the need for determining a gold standard for defining and measuring malnutrition.
