AIM:To investigate the incidence of gastroesophageal reflux disease(GERD) and its related risk factors in Uygur and Han Chinese adult in Urumqi,China.METHODS:A population-based cross-sectional survey was undertaken in a total of 972 Uygur(684 male and 288 female) aged from 24 to 61 and 1023 Han Chinese(752 male and 271 female) aged from 23 to 63 years.All participants were recruited from the residents who visited hospital for health examination from November 2011 to May 2012.Each participant signed an informed consent and completed a GERD questionnaire(GerdQ) and a lifestyle-food frequency questionnaire survey.Participants whose Gerd Q score was ≥ 8 and met one of the following requirements would be enrolled into this research:(1) being diagnosed with erosive esophagitis(EE) or Barrett's esophagus(BE) by endoscopy;(2) negative manifestation under endoscopy(non-erosive reflux disease,NERD) with abnormal acid reflux revealed by 24-h esophageal pH monitoring;and(3) suffering from typical heartburn and regurgitation with positive result of proton pump inhibitor test.RESULTS:According to Gerd Q scoring criteria,340 cases of Uygur and 286 cases of Han Chinese were defined as GERD.GERD incidence in Uygur was significantly higher than in Han Chinese(35% vs 28%,χ2 = 11.09,P < 0.005),Gerd Q score in Uygur was higher than in Han Chinese(7.85 ± 3.1 vs 7.15 ± 2.9,P < 0.005),and Gerd Q total score in Uygur male was higher than in female(8.15 ± 2.8 vs 6.85 ± 2.5,P < 0.005).According to normalized methods,304(31%) cases of Uygur were diagnosed with GERD,including 89 cases of EE,185 cases of NERD and 30 cases of BE;256(25%) cases of Han Chinese were diagnosed with GERD,including 90 cases of EE,140 cases of NERD and 26 cases of BE.GERD incidence in Uygur was significantly higher than in Han Chinese(31% vs 25%,χ2 = 9.34,P < 0.005) while the incidences were higher in males of both groups than in females(26% vs 5% in Uygur,χ2 = 35.95,P < 0.005,and 19.8% vs 5.2% in Han,χ2 = 5.48,P < 0.025).GERD incidence in Uygur male was higher than in Han Chinese male(26% vs 19.8%,χ2 = 16.51,P < 0.005),and incidence of NERD in Uygur was higher than in Han Chinese(χ2 = 10.06,P < 0.005).Occupation(r = 0.623),gender(r = 0.839),smoking(r = 0.322),strong tea(r = 0.658),alcohol drinking(r = 0.696),meat-based diet(mainly meat)(r = 0.676) and body mass index(BMI)(r = 0.567) were linearly correlated with GERD in Uygur(r = 0.833,P = 0.000);while gender(r = 0.957),age(r = 0.016),occupation(r = 0.482),strong tea(r = 1.124),alcohol drinking(r = 0.558),meat diet(r = 0.591) and BMI(r = 0.246) were linearly correlated with GERD in Han Chinese(r = 0.786,P = 0.01).There was no significant difference between Gerd Q scoring and three normalized methods for the diagnosis of GERD.CONCLUSION:GERD is highly prevalent in adult in Urumqi,especially in Uygur.Male,civil servant,smoking,strong tea,alcohol drinking,meat diet and BMI are risk factors correlated to GERD. 展开更多

The ethnic landscape of Urumqi has undergone significant changes since the 1980s, which has fostered greater ethnic diversity. However, little is known about the changing patterns of spatial segregation among ethnic groups. By using the Urumqi census data from 1982 to 2010, this study examines the level of residential segregation of Uighur from Hart and the level of residential segregation of Kazak, Hui, Mongolia and other ethnic minority groups from the majority Han and Uygur population by the indices of dissimilarity and exposure. Then it assesses a regression between residential segregation and the percentage of the ethnic groups. Finally, it finds out whether there exists a regression between residential segregation and the percentage of the ethnic groups. The result reveals that Kazak population is the most segregated group from Han and Uygur, although the level of segregation has declined from 1982 to 2010. Uighur people experienced lower level of segregation from Han between 1982 and 2000, but has gradually increased, particularly from 2000 to 2010; this unexpected change of the segregation for Uighur group might be associated with 7.5 Events. The findings of the study show that the growth of the Han population is negatively associated with segregation of the ethnic groups in a district, and that the association between the percentage of population and segregation was uniform for Uighur, Hui and Kazak: the higher percentage of an ethnic group in a district, the lower level of segregation. 展开更多
