Abstract | OBJECTIVES: To evaluate the safety of moxa smoke, especially to provide quantitative information and details for the occupational prevention of acupuncturists. METHODS: We combined the questionnaire-based cross-sectional survey and lung function testing-based historical retrospective cohort research to investigate the safety of moxa smoke exposure (MSE) among acupuncturists. A mathematical regression model was established to quantitatively evaluate the relationship between moxa smoke exposure and the respiratory health of the acupuncturist. The smoke exposure time of the acupuncturist and the prevalence of abnormal respiratory symptoms or diseases were also evaluated. RESULTS: (1) The cross-sectional research showed that the incidence of expectoration (18.7%) and rhinitis (22.7%) was the most common respiratory symptom and disease after MSE. No statistical difference was found between smoke exposure time of the acupuncturist and the prevalence of abnormal respiratory symptoms or diseases, except the prevalence of rhinitis and shortness of breath (P < 0.01). Regression model for the incidence of first three symptoms (expectoration, shortness of breath, and wheezing) from the cross-sectional survey indicated that the weight coefficients of factors associated with moxa smoke were lower than those of factors unrelated to moxa smoke, such as gender and personal history of respiratory diseases. (2) Historical retrospective cohort research showed that there was no significant difference in the % predicted PEF. No statistic difference was found between the exposed and nonexposed group in large airway function indexes (% predicted FEV1, % predicted FVC, and % predicted FEV1/FVC) and small airway function indexes (% predicted FEF25, % predicted FEF50, % predicted FEF75, and % predicted MMEF), either. Especially, the % predicted MVV among males (106.23 ± 2.92 vs. 95.56 ± 1.92, P < 0.01 and % predicted VC among females (100.70 ± 1.59 vs. 95.91 ± 1.61, P < 0.05) between the two groups had statistical significance, but did not cause pulmonary ventilation dysfunction. CONCLUSIONS: MSE has no significant effect on the respiratory health of acupuncturists.
