“…One Nigerian study showed that the prevalence of H. pylori infection was lower in children from families of higher socioeconomic status [27]. The poor socioeconomic status of people in the south of Iran was correlated with a higher incidence of infection (p<0.05) [28]. Our data is thus in line with these findings of others previous studies [26][27][28].…”

Aim: H. pylori infection is predominantly acquired in early childhood. The aim of the present study was to determine the prevalence of H. pylori infection and to identify factors associated with the infection in Muong children living in Vietnam. Materials and methods:In a cross-sectional study 918 asymptomatic individuals of all generations living together in the same home were selected from 219 households, based on cluster sampling of residential location in Hoabinh Province, Vietnam. H. pylori infection status was determined by serology test on samples obtained at each visit. A questionnaire was filled out at the start of the study. H. pylori serology data were analyzed using χ 2 test and logistic regression models. Results Conclusion:The first community-based study in Muong population showed familial clustering in multi-generation population and supported the hypothesis of person-toperson transmission in H. pylori infection

“…in Rondônia, Brazil, in a sample of participants aged 11-20 years, evaluated in 2010 [24], and 82% in Iran, in subjects aged below 15 years, evaluated in 2006 [25]. In Portugal, the first national study addressing H. pylori prevalence (assessed by serology), published in 1994, showed that the prevalence of infection among children aged between 3 and 14 years was 46.2% [26].…”

a b s t r a c tBackground: Helicobacter pylori infection is acquired mainly during childhood, but it may occur throughout life. Understanding the determinants of infection at different ages is essential to clarify dynamics of H. pylori related diseases and to design preventive strategies. Aim: To estimate the prevalence of H. pylori infection at the age of 13 and the incidence after a 3-year follow-up and to identify risk factors for infection. Subjects and methods: Adolescents born in 1990 were recruited in schools from Porto. Whole-cell anti-H. pylori IgG antibodies were quantified by ELISA. Prevalence ratios (PR) and incidence rate ratios (RR) adjusted for parental education were computed at baseline (n = 1312) and at follow-up (n = 280). Results: The prevalence was 66.2%, lower in subjects with more educated parents (PR = 0.72, 95%CI: 0.63-0.82), and higher for those having more than one sibling (PR = 1.10, 95%CI: 1.02-1.19) and for smokers (PR = 1.11, 95%CI: 1.02-1.20). The incidence was 4.1/100 person-years. Smoking (RR = 2.35, 95%CI: 1.16-4.75) and type of school (RR = 0.38, 95%CI: 0.16-0.95) were associated with the incidence of infection. Conclusions: Prevalence and incidence of H. pylori infection were high, suggesting that gastric cancer will remain an important public health problem in this generation of Portuguese. We identified smoking as a modifiable risk factor for infection.

“…The H. pylori infection rate in the Iranian population was reported to be 57-91%. [13][14][15][16][17] The prevalence of H. pylori infection in patients without dyspepsia would need to be examined in order to prove the relationship. Another way to evaluate the role H. pylori in dyspepsia would be to examine the improvement in symptoms after the infection has been cured.…”

Although Helicobacter pylori (H. pylori) infection has been known to be associated with several upper gastrointestinal disorders such as peptic ulcer and gastric cancer, the relationship between H. pylori infection and dyspeptic symptoms remains controversial. Furthermore, it is still not clear which factors are associated with H. pylori infection in the Iranian population. We investigated the prevalence of H. pylori infection in dyspeptic patients and factors associated with H. pylori infection in the Iranian population. In this cross-sectional study, 303 patients with dyspeptic symptoms underwent endoscopy. Clinical data and a questionnaire about gastrointestinal symptoms were collected from each patient. H. pylori status was evaluated by histological examination. Among the 303 patients, 263 (86.8%) were found to be positive for H. pylori. The prevalence of H. pylori infection decreased significantly with age. There was no difference in the prevalence of H. pylori infection between the patients with and those without a family history of gastroduodenal diseases. Among 250 patients with abdominal pain, 219 (87.6%) were infected with H. pylori. Among 211 patients with epigastric abdominal pain, 185 (87.7%) were infected with H. pylori. It was observed that belching was significantly associated with H. pylori infection (P = 0.03). Dyspepsia triggered by the consumption of tea was higher in H. pylori-positive patients than in H. pylori-negative patients (P=0.03). The prevalence of H. pylori infection in dyspeptic patients was quite high in Iran. Belching and dyspepsia triggered by tea consumption was related with H. pylori infection.
