Abstract

This study aimed to determine the seroepidemiology of Helicobacter pylori infection in Tepehuanos (an indigenous ethnic group living in rural Mexico). The prevalence of anti-Helicobacter pylori IgG antibodies was examined in 156 Tepehuanos in Durango State, Mexico, using an enzyme-linked immunoassay. In addition, sociodemographic, clinical, and behavioral characteristics of Tepehuanos associated with seropositivity were investigated. In total, 103 (66%) of the 156 participants (mean age years) had Helicobacter pylori IgG antibodies. Fifty-four (52.4%) of the 103 seropositive individuals had Helicobacter pylori IgG antibody levels higher than 100 U/mL. Males and females had comparable seroprevalence of Helicobacter pylori infection and Helicobacter pylori IgG antibody levels. The seroprevalence was significantly higher in women with pregnancies than those without this obstetric characteristic. Logistic regression showed that Helicobacter pylori infection was positively associated with low education (OR = 3.37; 95% CI: 1.13–10.00; ) and laborer occupation (OR = 2.71; 95% CI: 1.14–6.42; ). This is the first report of seroprevalence and contributing factors for Helicobacter pylori infection in Tepehuanos and of the association of Helicobacter pylori infection with laborer occupation. Results warrants further research.
