[Investigation of Laryngopharyngeal Reflux Prevalence and Risk Factors in Otolaryngology].

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.
