ABSTRACT

Objective To investigate the distribution of Helicobacter pylori (Hp) infections among general population in Tianjin. Methods Individuals (n=11 096) who visited our hospital for medical examination and H. Pylori infection screen were included in the research objects. Rapid urease method was utilized to rapidly detect H. pylori infection among the popultion. Individuals were grouped based on their gender, age and occupations, and then were analyzed. Results H. pylori-positive rate was 30.52%(3 386/11 096) in 11 096 individuals, in which there were 34.77%(1 784/5 131) male and 26.86%(1 602/5 965) female respectively. Individuals were divided into 5 groups according to their ages19 to 29 years old group, 30 to 39 years old group, 40 to 49 years old group, 50 to 59 years old group, 60 to 69 years old group and 70 to 92 years old group. The positive rates of H. pylori increased with age19.50%( 379/1 944 ) in 19-29 years old group, 25.82%(650/2 517 ) in 30-39 years old group, 31.59%( 908/2 874 ) in 40-49 years old group, 37.48%(915/2 441 ) in 50-59 years old group, 41.09%( 353/859 ) in 60-69 years old group and 39.18%(181/462) in 70-92 years old group. The differences in positive rates between different age groups were all of statistically significant (P<0.05). Individuals were also divided into seven groups according to their occupations medical worker group, worker group, teacher group, engineer group, clerk group, civil worker group and other career group. The positive rates of H. pylori infection were 25.42%(586/2 305), 29.35%(1 062/3 618), 30.61%(360/1 176), 32.49%(116/357), 33.44%(205/613), 34.52%(455/1 318)and 35.23%(602/1 709) respectively. The positive rate was 25.42% (586/2 305) medical workers, which was lower than that of other occupation groups with significant difference (P<0.002). Conclusion Good management of H. pylori diagnosis and treatment in mid-dle age and elderly together with popularizing knowledge of H.pylori prevention can effectively reduce H.pylori incidence.
