“…Factors linked to household conditions, such as present family size, were not relevant determinants of H. pylori infection status in this adult population, a finding also observed by others, both in developed and in developing countries. In most of these studies, a clear association was seen between socioeconomic status and overcrowding in childhood, but not with present household conditions [21,22,11]. Although we did not evaluate socioeconomic status and overcrowding during the childhood of the subjects involved in this survey, we had previously demonstrated that 75.4% of the children living in this community were infected.…”

We investigated the prevalence and the risk factors for infection with Helicobacter pylori in a randomly-selected population of adults from a low-income community in Northeastern Brazil. Helicobacter pylori infection was determined by ELISA. Risk factors were assessed using a structured interview. Two hundred and four individuals were included in the study, including 49 males and 155 females, ranging from 18 to 80 years old. Overall, 165 of 204 participants (80%) were H. pylori positive, without significant gender differences (p= 0.49). The infection rate was of 84.7% in subjects 18 to 30 years of age, increasing to 92% in subjects 46-60 years old. Above 60 years old, the prevalence decreased slightly. As a whole, the prevalence of infection did not increase significantly (p=0.147) with age. There were no significant differences in the prevalence of H. pylori infection, when patients were classified by age, smoking habit, educational level, alcohol consumption, the number of persons per room, the number of children per household, the number of adults per household, cup-sharing, household pets, toilet location, number of persons per bed and medical history of antibiotic and raw vegetable ingestion. In conclusion, no risk factors associated with infection was found in these adults, suggesting that the infection, even in a poor population, may be acquired predominantly during childhood; the relatively high prevalence that we observed may be more due to a cohort effect than to acquisition of infection during adulthood.

“…However, there is lack of consensus on the association between H pylori prevalence and some of these factors such as age and gender. Even though recent epidemiological studies report an age-dependent increase in H pylori positivity, various studies describe that the prevalence of H pylori infection does not differ with age (Graham et al, 1991;The EUROGAST Study Group., 1993;Moayyedi et al, 2002;Rodrigues et al, 2005). Similar controversies exist on the association between H pylori positivity and gender.…”

“…Although, another study conducted by Moges et al demonstrated that H. Pylori infection is related to alcohol abuse (Moges et al, 2006) but due to cultural and religious reasons we did not asked about the use of alcohol by study participants. Literature reveals that H. Pylori infection is more prevalent in children and younger ages (Moayyedi et al, 2002). In our study also H. Pylori infection is more prevalent among patients with young age.…”

“…It has been shown that 50% adult in developed countries and 90% adults in developing countries were positive of serum antibodies against H. pylori (Wu et al, 2003). The critical period at which H. pylori is acquired, is during the childhood, especially in the developing countries and areas of overcrowding and socioeconomic deprivation (Moayyedi et al, 2002).…”

“…Some studies reported that alcohol is protected against infection while coffee had the opposite effect, but these results are variable (Wu et al, 2003). Epidemiological studies demonstrate the incidence of H. pylori infection appears to be higher in children than in adults, possibly due to lower standards of personal hygiene in younger populations (Moayyedi et al, 2002).…”

Background: It is known that blood group antigens are related to the development of peptic ulcer and gastric carcinoma. Infections due to H. pylori are most widespread among the developing regions due to poor standard of public health. This study sought to determine the association of H. pylori with ABO blood groups, age, gender, and smoking status among inpatients at a public sector hospital in Karachi. Materials and Methods: A cross-sectional study was conducted at endoscopy suite at a public sector hospital in Karachi in the year 2011. All the symptomatic patients coming for upper GIT endoscopy were included in this study. Results: Biopsy for histopathology was taken from 93 patients, with an age range from 15-65 years. Age group of 15 to 20 years was found to be associated with H. pylori infection but without significance (p-value 0.83). In all, 36 (38.7%) turned out to be H. pylori positive with a significant male preponderance (p=0.04). Distribution of ABO blood groups in H. pylori positive group were A=31.4%, B=15.4%, AB=25.0% and O=53.7%, with a statistically significant link for blood group O (p=0.05) . Rhesus factor was also compared but significant relationship was evident (p-value 0.73). Conclusions: This study demonstrated that H. pylori infection can be related to ABO blood group, middle age persons and male gender. People of blood group O are more prone to develop infection related gastritis, ulcers, and even perforations, so they should be more cautious against transmission of the bacterium.

Abstract: Male gender, living with a partner and poor adult socioeconomic conditions are associated with increased risk of H. pylori infection.
