The purpose of an analysis of the risk factors of Tangshan City in rural areas of chronic obstructive pulmonary disease (COPD); 2 to provide a theoretical basis for the prevention and treatment of Tangshan City in rural areas COPD. Method 1 uses a stratified cluster random sampling method, randomly selected from the three counties (in coastal areas, mountainous regions and plains were Nanpu Development Zone the Qian'an city (county), Kaiping District), and then from a random sample of six administrative villages, census resident population over the age of 40, including questionnaires and physical examination. 190 cases diagnosed in the census COPD patients (male 120, female 70 cases) as the case group selected from the neighborhood of each patient by gender, age and other conditions of two healthy (to meet normal lung function, except for people with asthma, chronic bronchial pulmonary disease, tuberculosis, lung cancer, lung trauma surgery, nearly three months suffered from other serious acute infectious diseases and respiratory diseases) Logistic regression was used as the control group (male 240 cases, 140 cases) model analysis of risk factors. Results 1 single factor analysis found that dust, chemical substances, such as the history of occupational exposure (OR = 4.74), coal, biofuels as a fuel (OR = 1.80), as a way of heating (OR = 2.39) kang, hibachi, smoking (OR = 3.97), daily smokers gt; 10 cigarettes (OR = 3.29), years of smoking gt; 20 years (OR = 4.73), parents respiratory disease, family history (OR = 2.23), childhood cough (OR = 2.40 ) and the life, work stress or fatigue (OR = 3.35) and other factors associated with COPD with statistical significance. 2 through trend chi-square test, the worse the indoor ventilation, the greater the smoking index, the smaller the body mass index, the greater the risk of occurrence of COPD, the linear trend test was statistically significant. 3 single factor analysis did not find the type of housing, outdoor pollution, poor kitchen ventilation, smoking cessation, smoking type, passive smoking, brothers and sisters, respiratory disease, family history, history of hospitalization due to respiratory diseases, allergies before the age of 14 colleagues and family tensions between associated factors such as the occurrence of COPD. 4 Multivariate Logistic regression analysis revealed that occupational exposure (OR = 6.00), live, work stress or fatigue (OR = 4.09), smoking (OR = 3.95), used the kang hibachi as a method of heating (OR = 3.28), indoor ventilation poor (OR = 2.39), the parents family history of respiratory disease (OR = 2.34) and low body mass index (OR = 2.16) were independent risk factors of Tangshan City in rural areas suffering from COPD. Conclusion Occupational exposure to live, work stress or fatigue, smoking, with kang, hibachi for heating, poor indoor ventilation parents respiratory disease, family history and low body mass index is an independent risk factor for Tangshan rural areas suffering from COPD.
