Abstract：Objective To explore the prevalence of gastroesophageal reflux disease(GERD) among adult Tibetans in Gemo Township and to identify the related disease and risk factors of GERD.Methods Stratified random samples of adult Tibetans from Gemo Township were chosen to answer the gastroesophageal reflux disease questionnaires(GerdQ). According to GerdQ,a cut-off score of 8 was determined to discriminate between GERD patients(sum score≥8) from controls(sum score<8). Software SPSS17.0 was used to perform the Chi-square test and Logistic regression analysis.Results 787 valid questionnaires were collected. The incidence of GERD was 14.74% in the adult population of Gemo Township. GERD was more prevalent among those who were 40 years old and above, or overweight (IBM≥24) and among herdsmen. The main symptoms of GERD included heartburn(74.14%),reflux(69.83%) and acid reflux(55.17%).GERD had a close relationship with extraesophageal diseases,such as odontopathy,oral ulcer,pharyngitis,sinusitis,snoring,laryngitis and bronchitis. Logistic analysis showed that age,BMI,somiton tablets,spicy food,greasy food,high salt and lack of vegetables were the most likely risk factors for GERD.Conclusions GERD is prevalent among adult Tibetans in Gemo Township so that their quality of life is affected. We should try to improve the sanitary conditions of Tibetans,overcome the undesirable dietary habits and enhance the diagnosis and treatment of GERD.
