背景在佛教或道教的台湾居民中，烧香是室内颗粒物（PM）的常见来源，包括PM10和PM2.5，并可能对慢性阻塞性肺疾病（COPD）患者的健康状况产生不利影响。然而，很少有研究关注间歇性烧香对PM浓度水平和COPD患者健康状况的影响。本研究旨在探讨台湾地区慢性阻塞性肺疾病（COPD）患者的熏香暴露时间、室内空气污染水平和肺功能之间的关系。我们在7个时间点使用COPD评估测试（CAT）和肺功能测试评估了18例中重度COPD门诊患者。PM水平的变化进行了评估，在七个时间间隔使用广义估计方程。参与者主要为男性（84%），平均年龄为72.1（标准差（SD）+/- 9.3）岁，平均COPD持续时间为3.7（SD +/- 3.1）年。焚香后1小时，PM10和PM2.5水平与背景水平相同。烧香在短期内可能不会影响COPD患者的肺功能或症状严重程度。结果：1.焚香后1 h空气质量恢复到基线水平。COPD患者应避免在焚香的房间内停留1小时。样本量小和研究时间短可能会影响我们的结果。建议将来进行更大样本量和长期随访的纵向研究。
Background. Among Buddhist or Taoist Taiwanese residents, burning incense is a common source of indoor particulate matter (PM), including PM10 and PM2.5, and can adversely affect the health status of patients with chronic obstructive pulmonary diseases (COPD). However, few studies have focused on the effects of intermittent burning of incense on PM concentration levels and the health status of patients with COPD. This correlational cohort study aimed to investigate the association between burning incense exposure duration, indoor air pollution levels, and lung function in patients with COPD in Taiwan.Methods. We assessed 18 outpatients at seven time points with moderate-to-severe COPD using the COPD Assessment Test (CAT), and lung function tests. PM level changes were assessed at seven intervals using generalized estimating equations.Results. Participants were primarily male (84%), with a mean age of 72.1 (standard deviation (SD) +/- 9.3) years, and with a mean COPD duration of 3.7 (SD +/- 3.1) years. Both PM10 and PM2.5 levels were the same as the background levels 1 h after incense burning. Burning incense may not influence lung function or symptom severity in patients with COPD in a short-time period. Air quality returned to baseline levels 1 h after burning incense.Conclusion. Patients with COPD should avoid staying in rooms where incense is burnt, for up to 1 h. The small sample size and short study period may have influenced our results. Future longitudinal studies with larger sample sizes and long-term follow-ups are recommended.
