An epidemiological survey of laryngopharyngeal reflux disease at the otorhinolaryngology-head and neck surgery clinics in China
Abstract
Purpose: Using the Reflux Symptom Index (RSI), this nationwide study aimed to investigate the incidence, diagnostic status, risk factors, and common symptoms of adult laryngopharyngeal reflux disease (LPRD) at otorhinolaryngology-head and neck surgery (OHNS) clinics in China.
Methods: This multicenter cross-sectional survey began at the different institutions ranged from July to October 2017, and the duration was 12 months. A total of 90,440 eligible patients were finally enrolled from 72 medical institutions in China. All these patients completed the questionnaire based on RSI. In this study, LPRD was defined as RSI > 13.
Results: There were 9182 with LPRD among the 90,440 eligible participants (10.15%). However, only 1294 had a history of LPRD diagnosis among those with LPRD (14.09%). There were regional differences in the frequency of LPRD (P < 0.001). The proportions of patients with LPRD in males (vs. females), middle- and old-aged patients (vs. young), with current smoking history (vs. no smoking), and current drinking history (vs. no drinking) were significantly higher (all P < 0.001). Middle and old age, current smoking, and drinking history were independent predictors of LPRD (all P < 0.001, OR 1.240, 1.261, and 1.481, respectively). "Sensations of something stuck in throat or a lump in throat", "clearing throat", and "excess throat mucus or postnasal drip" were the most frequent clinical symptoms in patients with LPRD.
Conclusions: LPRD has a high incidence at the OHNS clinics in China. However, the diagnostic status of this disease is not optimistic. Older age, smoking, and drinking history were risk factors for LPRD.
