To evaluate the relationships between the nutritional status (obesity and underweight) and the pulmonary function parameters, we report a retrospective study including 55 COPD patients managed between 2010 and 2013. The mean age of our patients was 62,45 years. Sex-ratio was at 5.87. The nutritional evaluation of our patients showed that 18 \% of our patients had a BMI inferior to 18,5kg/m2, 41 \% of our sample had a normal nutritional status, 12\% had an overweight and 27\% of cases were obese. Ten per cent of our patients presented with stageI COPD, 21\% were at stage II and respectively 54\% and 12\% were at stages III and IV. Underweight was significantly associated with a lower lung function: average FEV1 in underweight patients was at 1.31 L (47\% of predicted values: pred) versus 1.56 L in non underweight patients (56\% of pred): p=0.02. Mean FVC was independent from underweight. The Tiffenau index was lower in underweight patient without reaching a statistically significative difference. Average FEV1 was similar in obese and non obese patients: 1.69 L (62\% of pred) versus 1.59 L (58\% of pred) p 0.06; Average FVC was significantly lower in obese patients: 2.57 L (76\% of pred) versus 2.30 L (65\% of pred): p =0.04. The Tiffenau Index was independent from obesity. The small airway{\textquoteright}s obstruction was significantly more important in underweight patients (p=0.04). Underweight seems to be associated with a lower pulmonary function in COPD. The nutritional care should play an important role in multidisciplinary COPD management.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/P2513}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/P2513.full.pdf}, journal = {European Respiratory Journal} }
