To investigate the risk factors of reflux esophagitis (RE) in farmers of Shandong province. Five hundred and fifty six peasants (aged from 34 to 90 years old) were randomly selected from the rural general population in Yantai area, Shandong province. All participants received a face to face interview for relating clinical symptoms. Upper gastrointestinal endoscopic and histopathologic examination were carried out. 101 (18.2%) patients were diagnosed endoscopically as RE. According to Los Angeles Classification system, the distribution of types was as follows: A: 36.6% (37/101), B: 56.4% (57/101), C: 3.0% (3/101), D: 4.0% (4/101). The gender (P < 0.001), age (P = 0.041), time engaged in farming (P = 0.040) of the subjects and the length from Z line to fore-tooth (P = 0.001) were correlated with the occurrence of RE. Smoking (OR 1.894, 95% CI 1.207 - 2.974), drinking strong tea (OR 2.900, 95% CI 1.651 - 5.092), using non-steroidal anti-inflammatory drugs (NSAIDs) (OR 2.159, 95% CI 1.166 - 3.997) and loose cardi
