Abstract

The present cross sectional study with comparison group was undertaken to assess the lung function of hairdressers by Peak Expiratory Flow Rate (PEFR) using Wright peak flow meter. Total 385 hairdressers and 770 controls were included in the study. PEFR was observed to be reduced in hairdressers compared with controls. The difference was significant (P < 0.01) above 45 years of age. Also with increasing duration of exposure observed PEFR was reduced than expected. Above 20 years of length of service, the difference was statistically significant (P < 0.01). Smokers in hairdressing occupation had reduced PEFR than in control group, though this difference was not significant. Thus, we conclude that hairdresser's environment adversly affects their lung function and smoking may potentiate the adverse effect.

摘要

本横断面研究设立了对照组，旨在使用赖特峰流速仪通过呼气峰值流速（PEFR）评估美发师的肺功能。该研究共纳入了385名美发师和770名对照者。观察发现，与对照组相比，美发师的PEFR降低。45岁以上人群的差异具有显著性（P < 0.01）。此外，随着接触时间的增加，观察到的PEFR低于预期。工作年限超过20年，差异具有统计学意义（P < 0.01）。从事美发职业的吸烟者的PEFR低于对照组，尽管这种差异不显著。因此，我们得出结论，美发师的工作环境会对其肺功能产生不利影响，吸烟可能会增强这种不利影响。
