The aim of this study is to investigate the association between incense burning exposure and chronic bronchitis in Taiwanese women and to investigate the effect of incense burning exposure on female lung function.
Methods:
This is a community-based case-control study. The study population was from the data bank of year 1999 Kao-Ping National Health Insurance System. Eligible cases and controls were female who were 40 years old and over and had lived in Kaohsiung city for 5 years and over. The study cases were those who were diagnosed with chronic bronchitis (ICD-9 code: 491) and without other respiratory diseases at least 2 times. The study controls were those who were healthy and had no other airway-associated diseases. Questions about potential environmental risk factors and information about pulmonary function tests were collected.
Result:
From July, 2002 to March, 2006, we recruited 600 study women (age: 63.5 ± 9.1 yrs). 60 women were definite chronic bronchitis who were satisfied the criteria for chronic bronchitis by American Thoracic Society (ATS) guideline; 530 were healthy controls who were not satisfied the criteria by ATS. The numbers (%) of incense burning exposure women and non-exposure women were, respectively, 39(65.0%) and 21(35.0%) in 60 definite chronic bronchitis, and 316(59.6%) and 214(40.4%) in 530 healthy controls. Compared to non-exposure women, incense burning exposure women had 1.31- (95% CI: 0.72–2.39) of developing definite chronic bronchitis, after adjusting for other covariates, but not significant. After adjusted for other potential confounders, FEV1 among women with incense burning exposure (FEV1: 1.52 ± 0.46；n = 332) had significantly reduced than those in non-exposure women (FEV1: 1.62 ± 0.47；n = 227) 86 mL（p = 0.01）. In addition, when compared with non-exposure women, FEV1 was significantly reduced 105 mL among women (FEV1: 1.50 ± 0.47；n = 265) who had incense burning exposure at least twice a day (p = 0.004). In the same way, we found the similar results in FVC.
Conclusion:
This study presents evidence that exposure to incense burning can impair lung function. In addition, incense burning exposure can increase the risk of chronic bronchitis among Taiwanese women, but not significant.
