    Back-ground: The 2011 GOLD document uses symptoms (health status), forced expiratory volume (FEV1) % and exacerbation history to categorize patients. However, there is no report validate the GOLD 2011 criteria because this stratification system was recently introduced. We aimed to assess the health status and distribution of COPD group especially in the elderly. Method: Patients` categories were defined with the EQ-5D index (EQ-5D index; ≥0.89 vs <0.89 as a surrogate for the COPD Assessment Test[CAT] ≥10 vs <10) in addition to lung function (FEV1% ≥50 vs <50). The COPD group was stratified from A through D according to 2011 GOLD. These patients were classified into the younger and the elderly group. Result: A total of 1266 patients who with obstructive pattern of pulmonary function test (PFT) and older than 40 years old were selected as COPD. The distribution of COPD group (A~D) was 61.2% (775; A), 33.0% (418; B), 2.4% (31; C), and 3.3% (42; D). The distribution of high risk group (group C & D) was similar between the elderly and the patients less than 66 year (3.1% [39; >65 yr], 2.7% [34; =<65], p=0.713). However, the high symptom groups (B+D) were more prevalent in the elderly than the patients less than 66 year (24.7% vs 11.7%, n=314 vs 148, p<0.001). The elderly had significantly lower EQ-5D score compared to patients younger than 65 year (0.93 vs 0.86, p<0.001).Conclusion: In the elderly COPD, the high symptom groups were more prevalent and health status was lower than the younger. Health status should be more focused to manage COPD especially in the elderly.
