1986年8月在中国北京开展了一项关于呼吸系统疾病危险因素的横断面研究。采用两阶段抽样方法，从农村地区、居民区和工业区随机选取40岁及以上的居民。此处呈现的分析基于以下成年人群样本：（1）愿意接受使用翻译成中文的英国医学研究委员会问卷进行访谈的人群（n = 3423）；（2）同时进行肺功能测量的人群（n = 3373）。阻塞性肺疾病定义为1秒用力呼气容积（FEV1）小于用力肺活量（FVC）的68%。七个变量被视为潜在危险因素或混杂因素：居住地区、性别、年龄、吸烟、呼吸系统疾病史、社会经济状况和家族因素。采用费尔德斯坦开发的一种改进的二元变量回归方法来调整比率。调整后的阻塞性肺疾病患病率在农村地区最高，在居民区最低。年龄增长、吸烟、社会经济地位低下以及呼吸系统疾病阳性病史与肺功能受损率显著升高相关。其他测量因素似乎与肺功能受损无关。
A cross sectional study of risk factors in respiratory diseases was carried out in August 1986, in Beijing, China. Inhabitants .gtoreq. 40 years old were selected at random from a rural area, a residential area and an industrial area, using a two stage sampling method. The analysis presented here is based on the sample population of adults who (1) were prepared to be interviewed, using the British Medical Research Council''s questionnaire translated into Chinese (n = 3423) and (2) had lung function measurements at the same time (n = 3373). Obstructive lung disease was defined as forced expiratory volume in 1s (FEV1) less than 68% of forced vital capacity (FVC). Seven variables were considered as potential risk factors or confounding factors: area of residence, sex, age, cigarette smoking, history of respiratory disease, socio-economic status and familial component. A modified binary variable regression method developed by Feldstein was used for the adjustment of rate ratios. The adjusted prevalence of obstructive lung disease was highest in the rural area and lowest in the residential area(s). An increase in age, cigarette smoking, low socio-economic status and positive history of respiratory diseases were associated with significantly higher rates of impaired pulmonary function. The other measured factors did not appear to be related to impaired pulmonary function.
