Prevalence of chronic obstructive pulmonary disease in Korea: The fourth Korean National Health and Nutrition Examination Survey, 2008

Abstract

Background and objective: Because the mortality and social burden associated with COPD is increasing, repeated surveys of the prevalence of COPD have been used to assess risk factors, detect potential patients, and establish early diagnoses and management protocols. We report the prevalence of spirometrically detected COPD in Korea in 2008, using data from the fourth Korean National Health and Nutrition Survey. Methods: Using nationwide stratified random sampling, based on the Korean Statistical Office census, 6840 subjects aged Ն19 years underwent spirometry, which was performed by four trained technicians, during 2008. The place of residence, levels of education and income and smoking status, as well as other results from a COPD survey questionnaire were also assessed.

Sinonasal inflammation in COPD: a systematic review

Unfortunately, it is unclear how many of the patients, who had nasal polyps or whether they were referred in preparation for surgery.…”

Prevalence and determinants of chronic obstructive pulmonary disease among a sample of adult smokers in Baghdad, Iraq, 2014

“…In other countries, such as Sweden, the USA, Japan and Korea, most COPD cases were mild (stage I) followed by moderate and severe stages (14,16,20,21). This difference could be attributed to including the general population or the early detection of cases due to better health care in these developed countries.…”

“…In Sweden it is 8.1 % according to the BTS guidelines and 14.3 % according to the GOLD guidelines in the population aged 45 years and older in the OLIN study 25 a prevalence comparable to 13.4 % in subjects aged 40 years and older in Korea 26 . COPD is underdiagnosed 6,27 .…”
