PURPOSE: The purpose of this study was to evaluate basic food intake in patients with severe COPD and chronic respiratory failure (CRF) and determine whether severity of disease and presence of CRF have influence on food consumption.
METHODS: The study included two groups of patients with COPD: group I 50 patients with severe COPD and CRF and group II 55 patients with moderate COPD. Body Mass Index (BMI) and waist circumference were measured, pulmonary function tests (PFT) and blood gas analyses (BGA) were performed in all patients. Patients filled out Food frequency questionnaire witch include: demographic, habit and basic food intake information.
RESULTS: In group I there were 41 male and 9 female mean age 58±2.8years, PFT results were FEV1 34±3.2%, FEV1/FVC 48±\±10%. BGA results: PO2 6.9±5.5Kpa, PCO2 7.0±2Kpa, Sat 85±12%. In group II there were 42 male and 13 female, mean age 54 ± 8 years, PFT results were: FEV1 61%±8.9%, FEV1/FVC 59±5.3%. BGA analysis: PO2 9.1±10 Kpa, PCO2 5.6 ±4Kpa, Sat 93±7.8%. Average intake of some food items were (Group I vs. Group II): red meat 1 days/week (d/w) vs. 2.1 d/w, white meat 1.5 vs. 2.5 d/w, fish 0.2 vs. 0.8 d/w, milk 4 vs. 5 d/w, low-fat cheese 0.1 vs. l d/w, extra-fat cheese 3.1 vs. 4. d/w, eggs 1.5 vs. 2.2 d/w, white bread 5.8 vs.7 d/w, rice 2.1 vs. 3 d/w, fruits 2.2 vs. 3.8 d/w, vegetables 1.8 vs. 3 d/w industrial food 5.7 vs. 5 d/w. None reported Soya consumption and integral bread.
CONCLUSION: The study demonstrated that both groups of patients with COPD have inadequate food intake. Food is low in protein, vitamins and minerals and rich in fat. The effect of severity of disease and chronic respiratory failure did not reach statistical significance.
CLINICAL IMPLICATIONS: Malnutrition and weight loss significantly influence patients with COPD, new treatment for systemic effects of COPD should offer better treatment opportunities in order to achieve better health status.
