Incidence of gastroesophageal reflux disease in Uygur and Han Chinese adults in Urumqi

Figure 1 Relationship between occupation (civil servant), smoking, strong tea, alcohol drinking as well as body mass index and gastroesophageal reflux disease in Uygur and Han Chinese adults. A: For gastroesophageal reflux disease (GERD) males, civil servant ratio (OR = 1.49, 95%CI 1.44-1.54), strong tea ratio (OR = 5.36, 95%CI 5.29-5.41), alcohol drinking ratio (OR = 2.33, 95%CI 2.13-2.53); B: Body mass index (BMI) value (26.5 ± 3.1 vs 22.7 ± 3.0 for GERD males vs normal males, P < 0.005 and 26.5 ± 3.1 vs 23.8 ± 3.8 for GERD males vs GERD females, P < 0.01) were higher than those in normal males and in GERD females, respectively; while for GERD females, civil servant ratio (OR = 2.77, 95%CI 2.56-2.98), alcohol drinking ratio (OR = 6.81, 95%CI 5.62-8) and BMI value (23.8 ± 3.8 vs 21.4 ± 2.9, P < 0.05) were higher than those in normal females; C: For GERD males, civil servant ratio (OR = 1.64, 95%CI 1.59-1.7), strong tea ratio (OR = 2.3, 95%CI 2.23-2.36), alcohol drinking ratio (OR = 3.3, 95%CI 3.19-3.41), mainly meat ratio (OR = 2.35, 95%CI 2.28-2.42); D: BMI value (25.8 ± 3.5 vs 22.3 ± 2.7 for GERD males vs normal males, P < 0.005 and 25.8 ± 3.5 vs 23.8 ± 3.0 for GERD males vs GERD females, P < 0.01) were higher than those in normal males and in GERD females, respectively; while for GERD females, civil servant ratio (OR = 2.05, 95%CI 1.86-2.24), alcohol drinking ratio (OR = 4.44, 95%CI 3.61-5.27), mainly meat ratio (OR = 2.58, 95%CI 2.19-2.97) and BMI value (22.9 ± 3.8 vs 20.4 ± 2.9, P < 0.01) were higher than those in normal females. ^aP < 0.05 vs male of the same ethnic group; ^cP < 0.05 vs female of the same ethnic group.
