目的了解西安市某单位体检人群幽门螺杆菌(Hp)的感染状况及分布情况。方法采用14 C-尿素呼气试验法(14 C-UBT),检测受检人群548例Hp与14 C结合的每分钟衰变数(DPM),统计不同性别、不同年龄Hp感染情况,分析其影响因素,并提出防控措施。结果 Hp总感染率48.0%(263/548),其中男性Hp感染率47%(191/406),女性Hp感染率50.7%(72/142),两者比较差异无统计学意义(χ2=0.883,P>0.05)。Hp感染阳性率各年龄组间比较差异有统计学意义(χ2=12.495,P<0.05),40~49岁年龄组最高,20~29岁组最低,40~49岁年龄组Hp感染率与20~29岁、30~39岁、50~59岁、>60岁年龄组间两两比较差异均有统计学意义(χ2=5.881~63.835,P<0.05)。结论西安市某单位Hp感染率低于全国平均水平,与性别无关,与年龄有关。
Objective To understand the infection status and distribution of Helicobacter pylori (Hp) in a unit medical examination population in Xi’an. Methods 14 C-urea breath test (14 C-UBT) was used to detect the declination per minute (DPM) of 548 Hp and 14 C co-workers in the tested population. The incidence of Hp infection by gender and age was statistically analyzed Factors, and put forward prevention and control measures. Results The overall infection rate of Hp was 48.0% (263/548). The prevalence of Hp infection was 47% (191/406) in male and 50.7% (72/142) in female, the difference was not statistically significant (χ2 = 0.883 , P> 0.05). The positive rate of Hp infection in each age group was significantly different (χ2 = 12.495, P <0.05), the highest in the 40-49 age group, the lowest in the 20-29 age group, and the Hp infection rate in the 40-49 age group was 20 There was significant difference between the age of ~ 29 years, the age of 30 ~ 39 years, the age of 50 ~ 59 years and the age of> 60 years (χ2 = 5.881 ~ 63.835, P <0.05). Conclusions Hp infection rate in a unit of Xi’an is lower than the national average, has nothing to do with gender, and age-related.
