Seroepidemiology of Helicobacter pylori infection in a Mennonite community in Durango State, Mexico

Background:
The epidemiology of Helicobacter pylori infection among Mennonites (an ethnic group of German descent living in rural communities in Mexico) has not been previously studied.
Materials And Methods:
The prevalence of anti-H. pylori IgG antibodies was examined in 152 Mennonite individuals in Durango State, Mexico, using enzyme-linked immunoassays. Seroprevalence association with sociodemographic, clinical, and behavioral characteristics of the Mennonite community was also investigated.
Results:
In total, 77 (50.7%) of the 152 Mennonite participants (mean age, 38.4 ± 15.5 years) had H. pylori IgG antibodies, 35 (45.4%) of whom had H. pylori IgG antibody levels higher than 100 U/mL. Males and females had comparable seroprevalence rates of H. pylori and H. pylori IgG antibody levels. On the other hand, seroprevalence of H. pylori increased significantly with age and was significantly higher among women with history of deliveries and abortions than among those with no such obstetric characteristics. Logistic regression analysis of behavioral characteristics showed that H. pylori infection was associated with a low frequency of eating at restaurants and at fast food outlets (up to 10 times/year) (OR = 2.77; 95% CI: 1.28-5.98; p = .009), and eating meat (up to 3 days/week) (OR = 2.84; 95% CI: 1.36-5.91; p = .005).
Conclusions:
This is the first report on the seroprevalence of H. pylori among Mennonites, factors contributing to such infection, and the association of H. pylori infection with abortions and low frequencies of eating out of home and meat. Further research should be conducted on this topic.
Insights
Helicobacter pylori (H. pylori) infection seroprevalence was 50.7% in Mexican Mennonites. Factors like age, childbirth history, and dietary habits were associated with H. pylori infection.
Area of Science:
- Epidemiology
- Infectious Diseases
- Microbiology
Background:
- The epidemiology of Helicobacter pylori (H. pylori) infection in Mexican Mennonite communities remains unstudied.
- H. pylori is a significant global pathogen linked to various gastrointestinal diseases.
Purpose of the Study:
- To determine the seroprevalence of H. pylori infection among Mennonites in Durango State, Mexico.
- To investigate sociodemographic, clinical, and behavioral factors associated with H. pylori infection in this population.
Main Methods:
- Enzyme-linked immunoassays were used to detect H. pylori IgG antibodies in 152 Mennonite participants.
- Statistical analyses, including logistic regression, were performed to identify associated factors.
Main Results:
- The overall H. pylori IgG seroprevalence was 50.7% (77/152).
- Seroprevalence increased with age and was higher in women with a history of deliveries/abortions.
- H. pylori infection was associated with infrequent dining out (≤10 times/year) and low meat consumption (≤3 days/week).
Conclusions:
- This study provides the first report on H. pylori seroprevalence in Mexican Mennonites.
- Identified risk factors include age, obstetric history, and specific dietary behaviors.
- Further research is warranted to understand the implications of H. pylori infection in this unique population.

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.
