“…Because women are less likely to smoke than men in most countries, the prevalence of COPD is usually higher in men than women (7,8,23,24). In a study performed in Elazığ-Turkey, the prevalence of cigarette smoking was higher in men (58.7%) than in women (13.1%) (25).…”

Background: Chronic obstructive pulmonary disease (COPD) is an important cause of mortality worldwide.Aims: The aim of this study was to establish the prevalence of chronic obstructive pulmonary disease (COPD) in residents who were ≥40 years old and living in a heavily industrialised city of Turkey, Kocaeli, using the Burden of Obstructive Lung Disease Initiative questionnaire.Study Design: Cross-sectional study.Methods: 1035 residents ≥40 years old and living in Kocaeli were surveyed. Spirometry and the basic BOLD questionnaire was performed.Results: 946 subjects entered into the analysis. The prevalence of stage I or higher COPD was 13.3% (8.7% for women and 16.5% for men), the prevalence of COPD at GOLD stage II or higher was 7.1% (4.1% for women and 9.2% for men). We also noted a high prevalence of COPD in never-smokers. Conclusion:Besides cigarette smoking, occupational exposure to fumes, chemicals and dusts might have also contributed to the high prevalence of COPD noted in residents who were ≥40 years old and living in Kocaeli, Turkey.

“…Population-based surveys using spirometry have shown that the disease is often under-diagnosed in the US, Japan, Korea, Spain, Sweden, and South America (4,(6)(7)(8)(9)(10). There is a large difference among national COPD prevalence estimates depending on self-reported diagnoses (4).…”

“…However, it is not possible to differentiate asthma and COPD in an individual over 40 years old by spirometry alone (34)(35)(36), although the use of the post-bronchodilator spirometry value is supposed to reduce the false-positive cases. However, the spirometry criterion adopted in our study is the one most commonly described in the COPD documents (9,10) and used in epidemiological studies (37)(38)(39) and allows us to compare our results to those of O.A. Nascimento et al…”

“…Although cases enrolled in these analyses were confirmed using HRCT, the gold standard for diagnosing bronchiectasis (Ooi et al 2002), only patients with severe bronchiectasis requiring medical evaluation or health care utilization were enrolled as cases; those with asymptomatic or mild symptoms may not have been evaluated using HRCT, resulting in undetected bronchiectasis cases and underestimation of the prevalence of bronchiectasis. A growing body of evidence shows that the true prevalence of chronic respiratory diseases such as COPD, when evaluated using objective diagnostic methods, is much higher than prevalence estimated by reported or physician-diagnosed cases (Kim et al 2005). To overcome this limitation in previous studies, and estimate the true prevalence of bronchiectasis, the same diagnostic method should be performed in all study populations.…”

Bronchiectasis is one of the common chronic respiratory diseases and associated with respiratory morbidity and mortality. However, neither its prevalence nor its etiology is well-defined. We aimed to estimate the prevalence and risk factors of bronchiectasis in adults. In a retrospective study, we analyzed radiologic findings on chest computed tomography (CT) images performed as part of a health-screening program. From January to December 2008, 1,409 (24.6%) of 5,727 participants in the screening program of a health promotion center at a university hospital underwent chest CT scans based on the subject' s decision. Bronchiectasis was diagnosed, if there was abnormal bronchial dilatation in any area of both lungs on chest CT. Respiratory symptoms, smoking status, and past medical history were also analyzed to define clinical characteristics and risk factors of bronchiectasis. Of 1,409 patients (aged 23-86 years), who were screened for respiratory diseases using chest CT for one year in a health promotion center, 129 patients (9.1%) were diagnosed with bronchiectasis. The prevalence of bronchiectasis was higher in females than in males (11.5% vs. 7.9%, p = 0.022) and increased with age. Respiratory symptoms were reported in 53.7% of subjects. Previous history of tuberculosis (TB) (OR 4.61, 95% CI 2.39-8.88, p = 0.001) and age (OR 2.49, 95% CI 1.56-3.98, p = 0.001) were significantly associated with bronchiectasis. This retrospective analysis of chest CT findings in health screening examinees revealed a very high prevalence of bronchiectasis in adults. Previous TB infection is one of the major causes of bronchiectasis.
