ABSTRACT
<p><b>OBJECTIVE</b>To explore the prevalence of chronic obstructive pulmonary disease (COPD) and its risk factors in rural area in the southern part of Hubei province and to provide evidence for prevention and treatment.</p><p><b>METHODS</b>Using uniform scheme, procedures and questionnaire, a multistage survey for 1883 people in rural area in southern part of Hubei province was performed, and physical examinations and lung function tests were conducted for every participant.</p><p><b>RESULTS</b>In this survey, 186 COPD cases were identified with a overall prevalence of 9.88%. The prevalence for male was 13.68% while in female it was 6.46%. The prevalence was higher in males than in females (chi2 = 27.48, P< 0.001) and higher with the increase of age (chi2 = 79.22, P<0.001). Factors associated with COPD were identified in one-way variance model as follows: sex, age, smoking, time for cooking, using biomass fuels for in-door cooking, family history, frequent cough before age 14, low body index and having house remodelling in the last five years. Results from multivariate logistic regression analysis showed that sex (OR= 1.3010), age (OR = 1.8506), smoking (OR= 3.0118), cooking time (OR= 1.7651), family history (OR = 1.5278), frequent cough before age 14 (OR = 2.8965) were risk factors.</p><p><b>CONCLUSION</b>The prevalence of COPD in the southern part of Hubei province was high, suggesting that comprehensive intervention measures should be taken.</p>
