摘　　要：目的分析成都市某区小学教师嗓音疲劳状况及嗓音疾病患病情况。方法采用二阶段随机抽样调查方法抽取成都市某区小学教师389名,填写咽喉部症状调查表并行嗓音疲劳测试(观察嗓音疲劳测试失败率、平均声压级、平均基频)及频闪喉镜检查。结果 1本组教师咽喉不适症状以声音嘶哑最常见,其次为咽痛、咽干及发声易疲劳;2本组教师中189例患嗓音疾病,患病率为48.58%(疾病组),以慢性喉炎最常见,其次为声带息肉;余200例教师无明显嗓音疾病及发声功能障碍(嗓音正常组);3两组教师嗓音疲劳测试80dB SPL音量时失败率均明显高于75dB SPL时,且第1、2、10分钟嗓音疾病组的失败率高于嗓音正常组,差异有统计学意义(P<0.05);在第3分钟时,嗓音正常组平均声压级低于嗓音疾病组,第9分钟时,嗓音正常组平均声压级高于嗓音疾病组(均为P<0.05);在第1、3、4、6、7、10分钟嗓音疾病组平均基频高于嗓音正常组,差异有统计学意义(P<0.05)。结论嗓音疲劳在小学教师中普遍存在,且音量要求高时更易发生,其嗓音疾病的患病率也较高,应加强小学教师的嗓音保健,以改善嗓音疲劳症状,有利于降低罹患嗓音疾病的几率。Objective To investigate the prevalence of voice disorder and voice fatigue mental state in the pri- mary school teachers in a district of Chengdu. Methods A random sampling survey included 389 teachers from a dis- trict of Chengdu after they filled out the throat symptoms questionnaire, carried out voice fatigue tests, and strobo- scopic laryngoscopy. Results The most common voice of discomfort symptoms was hoarseness, followed by sore throat, dry throat and vocal fatigue. There were 189 teachers, 48. 5%, with voice disorders as the voice disorder group） and 200 teachers without throat and voice disorders as the control group. The failure rate was significantly higher at 80 dB than 75 dB, and for the study group, the failure rate was higher than that of the control group. The difference was statistically significant in 1,2 and 10 minutes between the two groups（P^0.05）. Conclusion Voice fatigue is very common in the primary school teachers and when high volumes are required, the voice fatigue is more serious. To reduce voice fatigue and the incidence of primary school teachers＂ voice disease, we should strengthen the teacher＇s voice health care.
