Insights
Breastfeeding does not appear to protect Kurdish children from Helicobacter pylori infection long-term. Factors like family size and housing density may increase H. pylori infection risk.
Area of Science:
- Medical Microbiology
- Pediatric Infectious Diseases
- Epidemiology
Background:
- Helicobacter pylori (H. pylori) is a prevalent bacterial infection linked to duodenal ulcers and gastric cancer.
- Risk factors for H. pylori acquisition are studied, but breastfeeding's role in prevention remains debated.
- This study investigates the long-term impact of breastfeeding on H. pylori infection in children.
Purpose of the Study:
- To evaluate the effect of breastfeeding on H. pylori infection in Kurdish children.
- To determine if breastfeeding offers protection against H. pylori infection in early childhood.
- To identify potential risk factors associated with H. pylori acquisition in the studied population.
Main Methods:
- A historical cohort study involving 221 children aged 2 years in Sanandaj, Iran.
- Children were categorized into breastfed and non-breastfed groups.
- H. pylori stool antigen testing was used to detect infection post-weaning; statistical analysis assessed associations.
Main Results:
- No significant difference in H. pylori infection rates was observed between breastfed and non-breastfed children (OR=0.809).
- Age was associated with H. pylori prevalence (P=0.008).
- Increased family size (OR=1.93) and housing density (OR=2.12) were linked to higher odds of infection.
Conclusions:
- Breastfeeding in infancy does not provide sustained protection against H. pylori infection in this Iranian cohort.
- Any protective effect of breastfeeding against H. pylori appears to be transient.
- Family size and housing density are identified as potential risk factors for H. pylori infection.
Objective:
Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in humans. Chronic colonization increases the risk of duodenal ulcer and gastric cancer. The risk factors for acquiring the infection have been extensively studied. However, there are conflicting results on the role of breastfeeding in the prevention of H. pylori infection. We conducted a study to evaluate the effects of breastfeeding on the H. Pylori infection in Kurdish children in Sanandaj, IR Iran.
Methods:
A historical cohort study was carried out from January 2011 through December 2012. Totally 221 children who were going to attain 2 years old during the study period were randomly enrolled. They were divided into two groups, i.e. breastfed and non-breastfed. We used H. pylori stool antigen test to detect infection in the selected group of children after age of 2 years and cessation of breastfeeding. Each group was subdivided into two subgroups, infected and non-infected. The associations of breastfeeding with H. pylori infection was assessed using statistical software.
Findings:
We found no difference in the odds of infection between breastfed and non-breastfed groups (OR=0.809, 95% CI [0.453-1.444]). An association between age and the prevalence of infection was found (P=0.008). There was an increase in the odds of infection as the family size grew (OR=1.93, 95% CI [1.04-3.6]) as well as increasing housing density (OR=2.12, 95% CI [1.10-4.10]).
Conclusion:
The data suggests that breastfeeding in infancy does not protect against H. pylori infection for long duration among studied children in Iran. The protective effects of breastfeeding, if any, are at most transient.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
