To investigate the prevalence of chronic obstructive pulmonary disease (COPD) in greenhouse farmers in Liaoning Province from 2006 to 2009.
By stratified-cluster random sampling, a survey of 5420 greenhouse farmers working in 835 plastic greenhouses was performed using uniform questionnaires in Shenyang, Chaoyang, and Jinzhou during 2006 and 2009. Physical examination and lung function tests were performed for all of the farmer. Blood routine examinations, blood gas analysis, and chest X-ray were performed for some of the subjects with respiratory symptoms and healthy controls. The chi-square test was used for comparison of the 2 sample rates, and the chi-square segmentation method for more.
The overall prevalence of COPD in greenhouse farmers in Liaoning Province was 17.5% (947/5420). Most patients were elderly, especially at the age of 50 years or older. The prevalence of COPD in greenhouse farmers in the plain areas was 15.6% (464/2981), which was lower than that in the mountains (20.2%, 246/1220) and coastal areas (19.4%, 237/1219), with a significant difference (the value of χ(2) were 13.04 and 9.35, all P < 0.0125). The prevalence of COPD in vegetable greenhouse farmers was 12.6% (273/2168), which was lower than that in fungus greenhouse farmers (24.3%, 263/1084), poultry greenhouse farmers (20.8%, 169/813) and flowers greenhouse farmers (17.9%, 242/1355), with a significant difference (the value of χ(2) were 71.49, 31.44 and 18.54, all P < 0.007). The prevalence of COPD was the highest (28.3%, 137/485) in farmers who had worked in the greenhouses for 3 to 5 years.
The overall prevalence of COPD in greenhouse farmers in Liaoning Province was higher than that reported in the rural areas nationally. Attention should be paid to the prevention and control of COPD in greenshouse farmers.
调查2006年至2009年辽宁省温室种植农户慢性阻塞性肺疾病（COPD）的患病率。
采用分层整群随机抽样方法，于2006年至2009年期间，在沈阳、朝阳和锦州对835个塑料温室中工作的5420名温室种植农户使用统一问卷进行调查。对所有农户进行体格检查和肺功能测试。对部分有呼吸道症状的受试者和健康对照者进行血常规检查、血气分析和胸部X线检查。采用卡方检验比较两个样本率，多个样本率比较采用卡方分割法。
辽宁省温室种植农户COPD的总体患病率为17.5%（947/5420）。大多数患者为老年人，尤其是50岁及以上者。平原地区温室种植农户COPD的患病率为15.6%（464/2981），低于山区（20.2%，246/1220）和沿海地区（19.4%，237/1219），差异有统计学意义（χ(2)值分别为13.04和9.35，均P < 0.0125）。蔬菜温室种植农户COPD的患病率为12.6%（273/2168），低于菌类温室种植农户（24.3%，263/1084）、禽类温室种植农户（20.8%，169/813）和花卉温室种植农户（17.9%，242/1355），差异有统计学意义（χ(2)值分别为71.49、31.44和18.54，均P < 0.007）。在温室工作3至5年的农户中，COPD患病率最高（28.3%，137/485）。
辽宁省温室种植农户COPD的总体患病率高于全国农村地区报告的患病率。应重视温室种植农户COPD的防治工作。
