To assess the prevalence of respiratory symptoms and their association with sociodemographic variables and with the characteristics of the work environment.
A cross-sectional study comprising 464 workers employed at ceramics manufacturing facilities located in the city of Várzea Grande, Brazil. Data were collected by means of a questionnaire comprising questions regarding sociodemographic variables, work environment characteristics, and respiratory symptoms. Data were analyzed by means of prevalence ratios and their respective 95% CIs between the dependent variable (respiratory symptoms) and the other explanatory variables. In the multivariate analysis, two hierarchical models were built, the response variables being "all respiratory symptoms" and "severe respiratory symptoms".
In the sample studied, the prevalence of "all respiratory symptoms" was 78%, whereas that of "severe respiratory symptoms" was 35%. The factors associated with "all respiratory symptoms" were gender, age bracket, level of education, type of occupation, exposure to dust, and exposure to chemical products. The factors associated with "severe respiratory symptoms" were level of education, exposure to dust, and exposure to chemical products.
Our results indicate the presence of upper and lower airway disease in the population studied.
评估呼吸系统症状的流行情况及其与社会人口学变量以及工作环境特征的关系。
本研究为横断面研究，共纳入了巴西瓦尔泽格兰德市的 464 名陶瓷制造企业的工人。通过问卷调查收集了社会人口学变量、工作环境特征以及呼吸系统症状等方面的数据。采用比值比及其 95%置信区间来分析因变量（呼吸系统症状）与其他解释变量之间的关系。在多变量分析中，建立了两个层次模型，因变量分别为“所有呼吸系统症状”和“严重呼吸系统症状”。
在研究样本中，“所有呼吸系统症状”的患病率为 78%，而“严重呼吸系统症状”的患病率为 35%。与“所有呼吸系统症状”相关的因素包括性别、年龄组、教育程度、职业类型、接触粉尘和接触化学制品。与“严重呼吸系统症状”相关的因素包括教育程度、接触粉尘和接触化学制品。
本研究结果表明，研究人群中存在上呼吸道和下呼吸道疾病。
