Helicobacter Pylori Infection
Conditions
Brief summary
This study intends to investigate the prevalence and risk factors of Helicobacter pylori (H. pylori) infection in the population of physical examination centers and communities. The physical examination population from the health management center of the Third Xiangya Hospital and the family-based community residents in Changsha were randomly selected. The H. pylori infection was detected by carbon-13 urea breath test (13C-UBT), and the related factors of H. pylori infection were investigated by questionnaire survey. The study provides supporting evidences to implement family-base H. pylori management to curb its intrafamilial spread. The results have important clinical implications in refinement of eradication strategies and impact on public health policy formulation for related disease prevention.
Interventions
DIAGNOSTIC_TESTcarbon-13 urea breath test (13C-UBT)
The H. pylori infection was detected by carbon-13 urea breath test (13C-UBT), a delta over baseline (DOB) of ≥4.0 was considered positive for H. pylori, and a DOB\<4.0 was considered negative.
BEHAVIORALquestionnaires
The related factors of H. pylori infection were investigated by questionnaire survey. The physical examination population participated in the questionnaires of the physical examination center, which included basic demographic characteristics and living habits, and filled out the questionnaires on the use of serving chopsticks at the same time. In the community, members of each eligible family were asked to complete a questionnaire including the details such family general information, basic information of every family member, personal living habits, past medical history, and so on.
