Abstract

OBJECTIVE

To determine the association of spirometric lung pattern with respiratory symptoms and to validate the American Thoracic Society respiratory questionnaire for lung function assessment among textile workers.

METHODS

This cross-sectional survey was conducted from August to December 2009 among adult textile workers of Karachi. Data was collected through the American Thoracic Society Division of Lung Disease respiratory questionnaire and the lung function was assessed by using a spirometer. Results of three acceptable readings of spirogram were recorded and the best of the three readings was used for analysis. SPSS 19 was used for data analysis.

RESULTS

There were 372 participants in the study with an overall mean age of 27±8.5 years. In linear regression analysis, forced expiratory volume in one second for workers who had chronic cough was -829.1 (confidence interval: -1273.1, -385.2), chronic wheeze -168.8 (confidence interval: -319.3, -18.2) and shortness of breath grade 2 -215.6 (confidence interval: -387.8, -43.4). In logistic regression model, after adjusting for covariates, odds of reduced percentage predicted forced expiratory volume in one second for workers who had chronic cough was 3.09 (confidence interval: 1.26, 7.56), chronic wheeze 1.98 (confidence interval: 1.05, 3.71) and shortness of breath grade 2 2.07 (confidence interval: 1.05, 4.07), while odds of reduced percentage predicted forced vital capacity for shortness of breath grade 2 was 2.35 (confidence interval: 1.05, 5.21). In logistic regression model 2, for assessing the effect of different combinations of chronic respiratory symptoms, the odds of reduced percentage predicted forced expiratory volume in one second for the combination of cough and wheeze was 2.08 (confidence interval: 1.05, 4.10), cough and shortness of breath grade 2 2.47 (confidence interval: 1.18, 5.18), phlegm and shortness of breath grade 2 2.59 (confidence interval: 1.23, 5.43), cough, wheeze and shortness of breath grade 2 4.64 (confidence interval: 1.97, 10.93)and cough, phlegm, wheeze and shortness of breath grade 2 4.18 (confidence interval: 1.68, 10.37).

CONCLUSIONS

A combination of chronic respiratory symptoms was best associated with decrements in lung function.

摘要

目的

确定肺量计检测的肺型与呼吸道症状之间的关联，并验证美国胸科学会呼吸问卷在纺织工人肺功能评估中的有效性。

方法

2009年8月至12月对卡拉奇的成年纺织工人进行了这项横断面调查。通过美国胸科学会肺病科呼吸问卷收集数据，并使用肺量计评估肺功能。记录肺量图三次可接受读数的结果，并将三次读数中的最佳值用于分析。使用SPSS 19进行数据分析。

结果

该研究共有372名参与者，总体平均年龄为27±8.5岁。在线性回归分析中，患有慢性咳嗽的工人一秒用力呼气量为-829.1（置信区间：-1273.1，-385.2），慢性喘息为-168.8（置信区间：-319.3，-18.2），气短2级为-215.6（置信区间：-387.8，-43.4）。在逻辑回归模型中，在调整协变量后，患有慢性咳嗽的工人一秒用力呼气量预测值百分比降低的比值比为3.09（置信区间：1.26，7.56），慢性喘息为1.98（置信区间：1.05，3.71），气短2级为2.07（置信区间：1.05，4.07），而气短2级的用力肺活量预测值百分比降低的比值比为2.35（置信区间：1.05，5.21）。在逻辑回归模型2中，为评估慢性呼吸道症状不同组合的影响，咳嗽和喘息组合的一秒用力呼气量预测值百分比降低的比值比为2.08（置信区间：1.05，4.10），咳嗽和气急2级为2.47（置信区间：1.18，5.18），咳痰和气急2级为2.59（置信区间：1.23，5.43），咳嗽、喘息和气急2级为4.64（置信区间：1.97，10.93），咳嗽、咳痰、喘息和气急2级为4.18（置信区间：1.68，10.37）。
