Abstract
Background: Helicobacter pylori in the United States has been declining in the
1990s albeit less so among blacks and Hispanics. As the socioeconomic status
of racial groups has evolved, it remains unclear whether the prevalence or the
racial and ethnic disparities in the prevalence of H. pylori have changed.
Methods: This is a cross-sectional study from a Veteran Affairs center among
patients aged 40–80 years old who underwent a study esophagogastroduode-
noscopy with gastric biopsies, which were cultured for H. pylori irrespective
of findings on histopathology. Positive H. pylori was defined as positive cul-
ture or histopathology (stained organism combined with active gastritis). We
calculated age-, race-, and birth cohort-specific H. pylori prevalence rates and
examined predictors of H. pylori infection in logistic regression models.
Results: We analyzed data on 1200 patients; most (92.8%) were men and
non-Hispanic white (59.9%) or black (28.9%). H. pylori was positive in 347
(28.9%) and was highest among black males aged 50–59 (53.3%; 44.0–
62.4%), followed by Hispanic males aged 60–69 (48.1%; 34.2–62.2%), and
lowest in non-Hispanic white males aged 40–49 (8.2%; 2.7–20.5%). In mul-
tivariate analysis, age group 50–59 was significantly associated with H. pylori
(adjusted odds ratio (OR), 2.32; 95% confidence interval (CI), 1.21–4.45)
compared with those aged 40–49, and with black race (adjusted OR, 2.57;
95% CI, 1.83–3.60) and Hispanic ethnicity (adjusted OR, 3.01; 95% CI,
1.70–5.34) compared with non-Hispanic white. Irrespective of age group,
patients born during 1960–1969 had a lower risk of H. pylori (adjusted OR,
0.45; 95% CI, 0.22–0.96) compared to those born in 1930–1939. Those with
some college education were less likely to have H. pylori compared to those
with no college education (adjusted OR 0.51; 95% CI, 0.37–0.69).
Conclusion: Among veterans, the prevalence of active H. pylori remains
high (28.9%) with even higher rates in blacks and Hispanics with lower
education levels.
Study Highlights
1. What is Current Knowledge?
a. The seroprevalence of Helicobacter pylori has been
declining in the United States in the 1990s.
b. There have been no large studies examining the
prevalence of active H. pylori infection in the Uni-
ted States since 1999–2000.
2. What is New Here?
a. The prevalence of active H. pylori infection in the
United States remains high (28.9%).
b. Racial and socioeconomic disparities in H. pylori
infection still exist, as prevalence rates are even
higher in blacks and Hispanics with lower educa-
tion levels.
Helicobacter pylori (H. pylori) infection affects 50–60% of
the world population [1,2] with marked geographic
variation [3]. H. pylori prevalence in developing
