[Effects of smoking on lung function in populations of Beijing and Guangzhou]
Objective:
To analyse the relationship between cigarette smoking and lung function in populations of Beijing and Guangzhou.
Methods:
Complete lung function and smoking habit data were recruited from 7983 men and women aged 35-59 in or around Beijing and Guangzhou. Comparisons were made between smokers and never smokers.
Results:
The mean values of FEV1/H2, FEF/H2 and FEV1/FVC are all lower in smokers than in never smokers for male smokers, the observed mean value of FEV1/H2 for each age group in smaller than the respective predicted value, and its descending trend with aging is more obvious than the predicted value when re-examination after 2-4 years; furthermore, smokers had higher prevalences of respiratory symptom and COPD.
Conclusion:
Cigarette smoking is harmful to lung function.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
