Assessment of prevalence and risk factors of helicobacter pylori infection in an oilfield Community in Hebei, China.

ABSTRACT: BACKGROUND:Only a paucity of large-scale perspective and cross-sectional studies on H. pylori infection in China have been published. The purpose of this study was to investigate the prevalence and risk factors for H. pylori infection among residents of Jidong community located in Hebei Province of China. METHODS:A perspective, cross-sectional study was conducted in Jidong community. Questionnaires and 13C-urea breath test were performed, and 10-ml blood samples were obtained for laboratory tests. RESULTS:Four thousand seven hundred ninety-six subjects were enrolled in this study, and 2506 (52.25%) were H. pylori positive. There was no difference in prevalence between both sexes (P?=?0.5974). Age (P?=?0.004) and education level (P?=?0.0128) were significantly associated with H. pylori infection, and there were statistical trends in the prevalence across five age subgroups (?2 test for trend?=?23.5; P?

Project description:BackgroundHelicobacter pylori infection is a significant burden to the public health in China as it can lead to various gastric diseases including peptic ulcers and gastric cancer. Since most infections occurred during childhood, it is therefore necessary to understand the prevalence and risk determinants of this bacterial infection in children. Herewith, we conducted a cross-sectional study in the Kuichong Subdistrict of Shenzhen City to assess the prevalence and risk factors of H. pylori infection among children.MethodsFrom September 2018 to October 2018, 1,355 children aged 6-12 years from four primary schools in the Kuichong Subdistrict of Shenzhen City were recruited. These children were screened for H. pylori infection using the 13C-urea breath test. In addition, parents were requested to fill out a standardized questionnaire. The chi-square test and multivariable logistic regression analysis were used to identify risk factors for H. pylori.ResultsAmong 1,355 children recruited in this study, 226 (16.7%; 95% CI [14.7-18.7]) were positive of H. pylori infection. Multivariable logistic regression analysis identified six factors significantly associated with H. pylori infection children including parent(s) with tertiary education level (OR: 0.64; 95% CI [0.46-0.89]), testing bottle feed temperature using the mouth (OR: 1.79; 95% CI [1.19-2.68]), sharing of cutlery between the feeding person and young children during meals (OR: 1.84; 95% CI [1.22-2.78]), eating fruit after peeling (OR: 2.56; 95% CI [1.4-4.71]), frequent dining out (OR: 3.13; 95% CI [1.46-6.68]) and snacking (OR: 1.43; 95% CI [1.01-2.01]).ConclusionsOverall, better educated parent(s) played a protective role against the acquisition of H. pylori infection in children. Testing bottle feed temperature using the mouth, cutlery sharing between the feeding person and young children, and snacking posed a lower but significant risk for H. pylori infection. Only eating peeled fruits and frequent dining out were associated with greater infection risks.

Project description:BackgroundHelicobacter pylori (H.pylori) infections are prevalent and recognized as major cause of gastrointestinal diseases in Ethiopia. However, Studies conducted on the prevalence, risk factors and other clinical forms of H.pylori on different population and geographical areas are reporting conflicting results. Therefore, this review was conducted to estimate the pooled prevalence of H.pylori infections and associated factors in Ethiopia.MethodsPubMed, Embase, Google scholar, and Ethiopian Universities' repositories were searched following the Preferred Items for Systematic review and Meta-analysis (PRISMA) guideline. The quality of included studies was assessed using the Newcastle-Ottawa Scale in meta-analysis. Heterogeneity between studies was assessed using Cochrane Q test and I2 test statistics based on the random effects model. Comprehensive meta-analysis (CMA 2.0) and Review Manager (RevMan 5.3) were employed to compute the pooled prevalence and summary odds ratios of factors associated with of H.pylori infection.ResultsThirty seven studies with a total of 18,890 participants were eligible and included in the analysis. The overall pooled prevalence of H.pylori infection was 52.2% (95% CI: 45.8-58.6). In the subgroup analysis by region, the highest prevalence was found in Somalia (71%; 95% CI: 32.5-92.6) and the lowest prevalence was reported in Oromia (39.9%; 95% CI: 17.3-67.7). Absence of hand washing after toilet (OR?=?1.8, 95% CI; 1.19-2.72), alcohol consumption (OR?=?1.34, 95% CI; 1.03-1.74) and gastrointestinal (GI) symptoms (OR?=?2.23, 95% CI; 1.59-3.14) were associated with H.pylori infection. The trend of H.pylori infection showed a decreasing pattern overtime from 1990 to 2017 in the meta-regression analysis.ConclusionThe prevalence of H.pylori infection remains high; more than half of Ethiopians were infected. Although the trend of infection showed a decreasing pattern; appropriate use of eradication therapy, health education primarily to improve knowledge and awareness on the transmission dynamics of the bacteria, behavioral changes, adequate sanitation, population screening and diagnosis using multiple tests are required to reduce H.pylori infections. Recognizing the bacteria as a priority issue and designing gastric cancer screening policies are also recommended.
