Objective:To investigate the prevalence and related risk factors of laryngopharyngeal reflux in otolaryngology. Method:During January 2019 to March 2019, the inpatients in otolaryngology were investigated by the questionnaire of reflux symptom index scale and the laryngopharyngeal reflux related risk factors were analyzed. Result:Among the 227 patients, 33 patients with suspected LPR contained 19 patients（20.7%） of 92 patients in the laryngopharyngeal group, 10 patients（16.1%） of 62 patients in the nasal group, and 4 patients（5.5%） of 73 patients in the ear group. LPR prevalence in the laryngopharyngeal group was statistically different from that in the ear group（P<0.05）. Univariate logistic regression analysis showed that age, gender, smoking, drinking and BMI were risk factors of LPR（P<0.01）. Multivariate logistic regression analysis indicated that BMI was an independent risk factor of LPR（P<0.01）. Conclusion:LPR had a high prevalence rate in otolaryngology related diseases, and appropriate synergistic anti-LPR treatment could be carried out while treating otolaryngology related diseases.
目的：调查咽喉反流（LPR）在耳鼻咽喉科住院患者中的患病率及相关危险因素。 方法：采用反流症状指数（RSI）量表对住院患者进行问卷调查，并对LPR的相关危险因素进行分析。 结果：接受问卷调查的患者共227例，疑诊LPR患者33例，其中咽喉组19例（20.7%），鼻组10例（16.1%），耳组4例（5.5%）。咽喉组LPR患病率与耳组有统计学差异（P<0.05）。单因素Logistic回归分析年龄、性别、抽烟、饮酒和BMI是LPR的危险因素（P<0.05），多因素Logistic回归分析显示，BMI是LPR的独立危险因素（P<0.05）。 结论：LPR在耳鼻咽喉相关疾病中有较高的患病率，在治疗耳鼻咽喉相关疾病的同时可以进行适当的协同抗LPR治疗。.
