Prevalence and Risk Factors of GERD in Indonesian Population-An Internet-Based Study

Aim: The purpose of this study was to determine the prevalence and risk factors of GERD in Indonesian population. Methods: An online survey was conducted using Survey Monkey (R), from August 2013 to June 2015. People who completed all questions were recruited as research subjects. The diagnosis of GERD and its impact on daily life were determined using GERD Questionnaire (GerdQ) score, and all possible factors were analyzed to determine their association with GERD. Results: 2045 subjects completed the survey; their mean was age 31.4 +/- 8.8 years and 52.8% were female. The prevalence of GERD was 57.6%; 21.9% reported a low impact and 35.7% a high impact on their daily life. GERD was significantly associated with age >50 years old (p = 0.002; odds ratio [OR] 3.179), male (p = 0.009; OR 1.268), low to middle educational level (p = 0.033; OR 1.238), and body mass index (BMI) > 30 kg/m(2) (p = 0.015; OR 1.509). Conclusions: The prevalence of GERD in Indonesia was 57.6%. Age > 50 years old, male, low to middle educational level, and obesity were risk factors for GERD.
