Abstract

OBJECTIVE

Exposures at hairdressers' work have been reported to lead to an increased risk of several health outcomes. The present study aimed to investigate the relations between occupational exposures and respiratory symptoms and lung function among hairdressers in Iran.

METHODS

We conducted a cross-sectional study to compare potential respiratory effects among 140 women working as hairdressers to such effects among 140 women working as office workers (administrative personnel). Both groups worked in Shiraz, Iran. Respiratory symptoms were assessed by a standard respiratory questionnaire. The questionnaire also inquired about substances used and workspace conditions, including ventilation type. Lung function levels were measured by spirometry.

RESULTS

Respiratory symptoms, including cough, wheezing, shortness of breath, and chest tightness were significantly more frequent in hairdressers compared to the reference group (p < 0.05). After controlling for potential confounders, hairdressers had a prevalence ratio (PR) of 2.18 (95% CI 1.26-3.77) for cough, 9.59 (95% CI 1.004-91.73) for wheezing, 2.06 (95% CI 1.25-3.39) for shortness of breath, and 3.31 (95% CI 1.84-5.97) for chest tightness compared to the reference group. Lung function parameters (including VC, FVC, and FEV1) were significantly reduced in hairdressers (p < 0.001). Absence of air conditioning predicted greater reduction in lung function (p < 0.05) in the exposed. Decrease in FVC with normal FEV1/FVC in the exposed group suggested existence of restrictive lung function.

CONCLUSIONS

This study provides evidence of increased prevalence of respiratory symptoms and restrictive lung function impairment among hairdressers in Iran.

摘要

目的

有报道称，美发师的工作接触会增加多种健康结果的风险。本研究旨在调查伊朗美发师职业暴露与呼吸症状和肺功能之间的关系。

方法

我们进行了一项横断面研究，比较了 140 名从事美发工作的女性和 140 名从事办公室工作（行政人员）的女性之间潜在的呼吸影响。两组均在伊朗设拉子工作。呼吸症状通过标准呼吸问卷进行评估。问卷还询问了所使用的物质和工作场所条件，包括通风类型。肺功能水平通过肺活量计测量。

结果

与对照组相比，美发师的呼吸症状（包括咳嗽、喘息、呼吸急促和胸闷）明显更为频繁（p<0.05）。在控制了潜在的混杂因素后，美发师的咳嗽患病率比（PR）为 2.18（95%可信区间 1.26-3.77），喘息为 9.59（95%可信区间 1.004-91.73），呼吸急促为 2.06（95%可信区间 1.25-3.39），胸闷为 3.31（95%可信区间 1.84-5.97）。与对照组相比，美发师的肺功能参数（包括 VC、FVC 和 FEV1）明显降低（p<0.001）。在暴露组中，空调的缺失预测肺功能下降更大（p<0.05）。暴露组中 FVC 下降而 FEV1/FVC 正常提示存在限制性肺功能障碍。
