Objectives: The purpose of this study was to compare the self-reported symptoms of occupational asthma, occupational rhinitis, and respiratory symptoms between a direct exposure to flour dust group and a non-exposure group from the bakery industry.
Methods: The participants were 62 workers directly exposed to flour dust and 30 non-exposed workers. The survey was composed of questions related to general characteristics. Korean self-reported respiratory symptoms(SNU-93), occupational asthma, and occupational rhinitis data was collected from April to July 2017.
Results: The smoking rate among the direct exposure to flour dust workers was 67.7% and the mean of working hours(11-12) was 96.8%. The SNU-93 questionnaire revealed that respiratory symptoms in the chest and wheezing or whistling were significantly higher among the direct-exposure group than non-exposure group. The response for occupational asthma symptoms was significantly higher in the direct exposure group(2.4 points) than in the non-exposure group(1.6 points).
Conclusion: In order to decrease the symptoms of these respiratory diseases among bakery workers exposed to flour dust, it is necessary to reduce working hours and the smoking rate. The performance of periodic medical examinations is needed to find abnormal respiratory diseases. In addition, workers who have been diagnosed with asthma and rhinitis should consider switching to a process that is not exposed to flour dust.
