Abstract:
Objective To investigate current status and the influencing factors of Helicobacter pylori (H.pylori) infection in Lhasa region.Methods From November 2015 to July 2016,a questionnaire survey was conducted among 1 000 individuals in Lhasa region and H.pylori infection was detected by 13C urea breath test.Chi-square test and multivariate Logistic regression analysis were performed for statistical analysis.Results Among 1 000 individuals,576 (67.60％) cases were infected by H.pylori.The H.pylori infection rate in people less than 60 years old was 59.32％ (538/907),which was higher than that of people no less than 60 years old (40.86％,38/93),and the difference was statistically significant (x2=11.765,P＜0.01).The higher the education level,the lower the infection rate of H.pylori (x2=16.381,P =0.001).The difference in the infection rate of H.pylori in different occupations was statistically significant (x2 =28.699,P＜0.01).The infection rate of H.pylori was lowest in mental workers (45.77％,119/260) and was highest in heavy labor worker (79.35％,123/ 155),and the difference was statistically significant (x2 =44.985,P＜0.01).The lower the family annual income,the higher the infection rate of H.pylori (x2 =84.472,P＜0.01).Raw meat intake (odd ratio (OR)=1.725,95％ confidence interval (CI) 1.192 to 2.249),dietary taste (OR=1.316,95％CI 1.056 to 1.564) and sharing dishware (OR=2.723,95％CI 1.973 to 3.431) were positively correlated with H.pylori infection (all P＜0.01),and family income was negatively correlated with H.pylori infection (OR=3.205,95％CI 2.358 to 4.056,P＜0.01).Conclusion The infection rate of H.pylori decreased in Lhasa region compared to that of 10 years ago,which may be due to the improved dietary habit as well as social-economic condition.
