Abstract:ObjectiveTo investigate the status quo of laryngopharyngeal reflux disease (LPR) in residents of Nanjing City in order to provide the basis data for clinic practice.MethodsMultilaterationrandomsampling was taken in performance of the epidemiological questionnaire survey among 2500 residents of Nanjing City. According to the grade standard of reflux symptom index (RSI), subjects with total fraction more than 13 were defined positive cases. The correlative factors were analyzed.ResultsAmong the 1950 cases with availability, 75 cases were positive. The prevalence rates of LPR were 3.77% in male and 3.95% in female respectively, with a total prevalence rate of 3.86%. The gender difference was statistically insignificant (P>0.05). Symptoms such as persistent throat clearing, hoarseness and dysphonia were mostly correlated with LPR. As for the patients’ age, the prevalence rate of the group aged from 51 to 70 was higher than those of other groups.ConclusionsThe prevalence rate of LPR in the residents of Nanjing City is 3.86%. Persistent throat cleaning, hoarseness and dysphonia are the major correlative factors. We should pay particular attention to the aged patients with symptoms mentioned above.
