Prevalence of Chronic Obstructive Pulmonary Disease in Kocaeli: An Industrialised City in Turkey

Abstract

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.

Kronik Obstrüktif Akciğer Hastalığı Olan Hastaların Fonksiyonel Performans ve Öz-Bakım Gücünün Belirlenmesi

“…It was reported that the global prevalence of COPD is 11.7%, and 3 million people die due to COPD every year (GOLD, 2022). Epidemiological studies conducted in the provinces of Kocaeli, Zonguldak, and Kayseri in Turkey reported the prevalence of COPD as 13.3%, 11.1%, and 17.6% (Arslan et al, 2013;Örnek et al, 2015;Timur et al, 2020). These rates were similar to the reported global prevalence of COPD.…”

Thyroid Gland Disease as a Comorbid Condition in COPD

“…However, the number of the female patients in our study was very low. In developing countries like Turkey, the higher rate of smoking and COPD among males is an expected situation [11]. In our study, the prevalence of TGD was found as 25% (3/12) in the female patients and 22% (65/297) in the male patients.…”

A multicenter family practitioners’ research on Chronic Obstructive Pulmonary Disease screening using the COPD Assessment Test

“…In the present study, the COPD prevalence was lower than the results of previous studies (Gunen et al ., 2008; Deveci et al ., 2011; Arslan et al ., 2013; Dikis et al ., 2015). There might be some reasons to explain the low frequency of COPD in the present study.…”
