声乐专业学生嗓音疾病调查分析

目的分析声乐专业学生嗓音疾病发病情况。方法采用整群随机抽样方法,分别调查502名声乐专业学生(观察组)和200名非声乐专业学生(对照组)嗓音疾病患病率、病种构成、性别与年龄分布等,比较两组间的差异。结果声乐专业学生嗓音疾病患病率(28.49%,143/502)高于非声乐专业学生(20.50%,41/200)(P<0.05),声乐专业学生中嗓音疾病以慢性喉炎为主(59.44%),其次是急性喉炎(34.27%);而非声乐专业学生主要是急性喉炎(56.10%),其次是慢性喉炎(39.02%);声乐专业学生中女生和18～22岁年龄段学生患病率分别高于同组男生和23～30岁年龄段学生及非声乐专业学生。结论声乐专业学生嗓音疾病患病率较非声乐专业学生高,且以年龄偏小者以及女生多见,正确指导发声训练提高呼吸功能对其防治有重要意义。
