ABSTRACT

Background:Gastroesophageal reflux disease(GERD)is a common disease,its incidence is related to geographic environment and race. Studies reported on epidemiology of GERD in minority groups are rare. Aims:To investigate the prevalence and related risk factors of GERD in She population in Ningde. Methods:Three natural villages of She population in Ningde were selected for undergoing the cluster random sampling method. GERD was diagnosed by gastroesophageal reflux disease questionnaire(GerdQ)with score ≥8,and questionnaire was used to detect the prevalence and risk factors of GERD. Results:A total of 936 residents completed the questionnaire,and 89 were diagnosed as GERD, the prevalence was 9. 50% . Univariate analysis showed that the risk of GERD was significantly increased in She population with body mass index(BMI)≥24 kg/ m2 ,intake of strong tea or oily diet(P all < 0. 01). Multivariate analysis showed that BMI ≥24 kg/ m2(OR = 3. 022,95% CI1. 917-4. 765),intake of strong tea(OR = 2. 145,95% CI1. 338-3. 438) and oily diet(OR = 2. 016,95% CI1. 208-3. 318)were the risk factors of GERD. Conclusions:The prevalence of GERD is high in She population in Fujian Province,and the etiology may be related to overweight and diet habit.
