Title Exhaled nitric oxide and spirometry in respiratory health surveillance
Bibliographic information 2011, Vol.61, p.108-114. Illus. 30 ref.
Abstract Exposure to pollutants in bakeries and hairdressing salons can cause airway syndromes varying from bronchial irritation to asthma. Workplace respiratory health surveillance aims to identify possible cases requiring further investigation. The objective of this study was to compare the performance of fractional exhaled nitric oxide (FE(NO)) and spirometry for health surveillance of apprentice bakers (ABs) and apprentice hairdressers (AHDs). Determinants of FE(NO) were also identified. Symptoms and physician-diagnosed asthma were evaluated by questionnaire. FE(NO) was measured and spirometry was carried out. Subjects with elevated FE(NO), airway obstruction (one-second forced expiratory volume (FEV1)/forced vital capacity (FVC) < 95th percentile) and atopy were identified. A total of 126 apprentices (59 ABs and 67 AHDs) participated. Twenty-nine (23%) apprentices had abnormal tests: four had associated high FE(NO) and airway obstruction, while 25 had either high FE(NO) or airway obstruction alone. Compared with ABs, AHDs had more asthma (38% versus 0%) and atopy (62% versus 6%). There was no difference in symptoms, smoking FE(NO) or airways obstruction. Among 97 subjects with normal tests, no differences were found between ABs and AHDs. Average FE(NO) was increased in atopic non-smokers compared with atopic smokers and non-atopic subjects. Smoking, a history of allergies, FEV1/FVC and respiratory symptoms were the main determinants of FE(NO).
