Abstract:Abstract OBJECTIVE To understand the characteristics of chronic obstructive pulmonary disease(COPD) in rural grassroots through screening and analyzing the characteristics of patients, so as to provide the basis for exploring early intervention measures. METHODS Combined with farmers physical examination work, it selected 580 cases of aged 40 ~ 79 with chronic cough, sputum, or breathing difficulties crowd in high-risk object in Yantou Town, Pujiang County from March 2017 to September 2017. Through simple lung function instrument, it measured the expected values of FEV1/FVC and FEV1% so as to select patients with COPD and measure the respiratory frequency and oxygen saturation index of patients, 6 min walking distance test, the quality of life scores and anxiety score questionnaire survey are conducted on the patients, and the results were analyzed. RESULTS 200 COPD patients are screened out, accounting for 12.66% of the high-risk objects. The prevalence rate of male group is significantly higher than that of female group, and the onset age is mainly over 60 years old. Some patients were found to have complications associated with COPD when screening. Most patients had a history of COPD risk factors, especially those with smoking. The incidence rate of COPD was generally faster, the oxygen saturation and exercise endurance tended to decline, and the quality of life was decreased, and some of them were anxious. CONCLUSION Simple pulmonary function instrument was suitable and feasible for screening rural basic COPD patients. The characteristics of COPD in rural grassroots suggested that patients had insufficient understanding of COPD and lack of attention, so it was of great significance to further explore early intervention measures.
