Abstract
BACKGROUND Helicobacter pylori (H. pylori) remains a major cause of gastroduodenal diseases. We aimed to evaluate the burden of this infection, particularly peptic ulcer disease in Vietnamese children. METHODS We enrolled consecutive children referred for esophagogastroduodenoscopy at two tertiary children's hospitals in Ho Chi Minh City, from October 2019 to May 2021. Children treated with proton pump inhibitors during the last two weeks or antibiotics for four weeks, and those having a previous or interventional endoscopy were excluded. H. pylori infection was diagnosed with either a positive culture or positive histopathology combined with a rapid urease test, or with a polymerase chain reaction of the urease gene. The study was approved by the Ethics Committee and written informed consent/assent was obtained. RESULTS Among 336 enrolled children aged 4-16 (mean: 9.1 ± 2.4 years; 55.4% girls), H. pylori infection was positive in 80%. Peptic ulcers were detected in 65 (19%), increasing with age, and 25% with anemia. cagA+ strains were detected at a higher rate in children with ulcers. CONCLUSIONS Prevalence of H. pylori and peptic ulcers is high among symptomatic Vietnamese children. It is crucial to have a program for early detection of H. pylori to reduce ulcer risk and gastric cancer later.

Factors Associated With Helicobacter Pylori Infection Among School-Aged Children From a High Prevalence Area in Vietnam. Int J Public Health 2023; 68:1605908.

Abstract
Objectives: The study aimed to identify prevalence of H. pylori infection and associated risk factors among pupils of Ho Chi Minh city (HCMC). Methods: A total of 1,476 pupils aged 6-15 years were enrolled in this cross-sectional study using multiple-stage sampling method. Infection status was assessed using stool antigen-test. A questionnaire was used to obtain socio-demographic, behavioral, and environmental factors. Logistic regression was performed to assess possible factors related to the infection. Results: Of the 1,409 children included in the analysis, 49.2% were male and 95.8% were of Kinh ethnicity. About 43.5% of parents completed college or university. The overall prevalence of H. pylori was 87.7%. Infrequency of handwashing with soap after toilet, the use of only water to clean after toilet, crowded living areas, larger family size, and younger age were independently contributing to an increased prevalence of H. pylori. Conclusion: H. pylori infection is highly prevalent in HCMC, and is associated with poor hygienic practices, crowded living areas, larger family size, and younger age. These findings highlight the importance of fecal-oral route and the attribution of crowded living conditions to the spreading of H. pylori in HCMC. Therefore, preventive programs should be set up with a focus on education of hygiene practices, and oriented to those living in crowded conditions.

Abstract
Objectives: There is no study on Helicobacter pylori (H. pylori) infection in pupils of Ho Chi Minh city (HCMC), the most overcrowded city in Vietnam. Therefore, the aim of this study was to estimate the prevalence of H. pylori and its geographical spread among school-aged children. Methods: A school-based cross-sectional study was conducted among 1854 pupils across 24 districts of HCMC in 2019. Multiple-stage sampling method was used to enroll pupils. We built a four-points index for geographical division based on population density and employees density to evaluate the link between H. pylori and crowded level. Stool samples were analyzed by monoclonal enzyme-immunoassay stool antigen-test to assess the infection status. Logistic regression was performed to assess possible factors related to H. pylori infection. Results: The overall prevalence of H. pylori was 87.7%. There was a linear increasing trend in the infection rate (p < 0.001) across the 4-points index of HCMC and this trend maintained within both age and gender subgroups (p = 0.02). Conclusion: Prevalence of H. pylori was high and it increased with population density or employees density. Therefore, it is crucial to plan and implement the reduction of H. pylori infection programs by targeting the highly concentrated population areas of HCMC.

Abstract
SETTING and OBJECTIVE: Exposure to pollutants is related to the type of dwelling inhabited. Besides tobacco smoke, indoor air pollution is a significant risk factor for chronic respiratory disease (CRD). The prevalence of CRD by type of dwelling was studied in Ho Chi Minh City, Viet Nam.DESIGN: A total of 1561 people living in four type of dwellings were enrolled. Information on respiratory health, lung function, dwelling characteristics and sources of indoor pollution was obtained using a symptom and demographics questionnaire and spirometry. The two main respiratory health outcomes were clinical chronic CRD (CCRD) and chronic obstructive respiratory disease (CORD) (forced expiratory volume in 1 sec/forced vital capacity <0.7). We used binary logistic regression adjusted for age, sex, time spent at home, smoking status, certain occupational exposures, previous tuberculosis, presence of pets, rats or cockroaches at home, wall dampness, biofuel use and use of airconditioning.RESULTS: The prevalence of CCRD (24.3%) and CORD (5.3%) in the type of dwellings studied were not similar (χ² P < 0.0001). CCRD and CORD prevalence was similar in tube houses and apartments. Compared to people living in apartments, those living in rental single rooms had a 46% higher risk of developing CCRD. The odds ratio of having CORD in people living in rental single rooms and in rural houses were respectively 4.64 (95%CI 1.97-10.5) and 2.99 (95%CI 1.21-7.37).CONCLUSION: Type of dwelling was associated with CCRD and CORD morbidity.
