PURPOSE: GOLD 2013 document has proposed multidimentional approach to assess COPD patients. The aim our study was to examine the exercise capacity, quality of life and body composition in patients with COPD according to the new GOLD classification.

METHODS: In this prospective study; patients were classified into four categories using the new GOLD classification. Symptoms were measured by COPD Assessment Test (CAT) and the modified Medical Research Council (mMRC) scale. Incremental shuttle walk test and SGRQ were performed. Bioelectrical impedance method was used for measurement of body mass (BMI) and fat free mass index (FFMI).

RESULTS: 77 patients (64 male, age 66.14±7.94 yrs, FEV1% 59.05±19.83) with COPD were classified into group A (26%), group B (41.6%), group C (5.2%) group D (27.3%). The most common co-morbidity was cardiovascular diseases (62,3%). There were statistically signifcant differences between the groups in dyspnea, walking distance and SGRQ domains (p<0.05). Dyspnea measurements with CAT and mMRC were compatible with each other and the four groups. Walking distance was highest in group A followed by C,B, and D respectively. All of the SGRQ domains in group B were higher (which means worse quality of life) than group C and were similar to group D. However, there was no statisticallly significance in BMI, FFMI and co-morbidities between the groups (p>0.05).

CONCLUSIONS: Exercise capacity and quality of life in group B were worse than the patients in group C and similar to the group D. Body composition measured by bioelectrical impedance method did not differ between A,B,C and D groups. However, exercise capacity and quality of life were similar in groups B and D.

CLINICAL IMPLICATIONS: Therefore, we recommend to evaluate the body composition with different methods and in larger populations with COPD according to the new GOLD classification.
