Gastroduodenal sequelae of H. pylori infection are distinguished; however, for the H. pylori infection and its implication in the development of anemia, iron has a significant health impact. We aimed to evaluate H. pylori infection-associated anemia by employing a logistic regression analysis model. A retrospective (case\u2013control) study design-based assessment of the H. pylori associated-anemia. The study area was geo-referenced by QGIS\/QuickMapServies. Descriptive and inferential statistical analyses were accomplished using the R-base\u2013R-studio (v-4.0.2)-tidyverse. A p-value &lt; 0.05 was the statistical significance cut-off value. A ggplot2 package was used for data representation and visualization. Mean \u00b1 SD age, Hb, MCV, ferritin, and RBC for overall study participants were measured to be 44.0 \u00b1 13.58, 13.84 \u00b1 2.49, 83.02 \u00b1 8.31, 59.42 \u00b1 68.37, and 5.14 \u00b1 0.75, respectively. Decreased levels of Hb (infected vs. uninfected: 13.26 \u00b1 2.92 vs. 14.42 \u00b1 1.75, p &lt; 0.001) ferritin (infected vs. uninfected: 48.11 \u00b1 63.75 vs. 71.17 \u00b1 71.14, p &lt; 0.001), and MCV (infected vs. uninfected: 81.29 \u00b1 9.13 vs. and 84.82 \u00b1 6.93, p &lt; 0.05) were measured to be associated with H. pylori infection when compared with H. pylori uninfected control group. Moreover, the magnitude (prevalence) of anemia (infected vs. uninfected: 78% vs. 21%, p &lt; 0.001), iron deficiency anemia (IDA) (infected vs. uninfected: 63.3% vs. 36.6%, p &lt; 0.001), and microcytic anemia (infected vs. uninfected: 71.6% vs. 46.1%, p &lt; 0.001) were significantly different among the H. pylori-infected participants. The higher likelihood of developing anemia (AOR; 4.98, 95% CI; 3.089\u20138.308, p &lt; 0.001), IDA (AOR; 3.061, 95% CI; 2.135\u20134.416, p &lt; 0.001), and microcytic anemia (AOR; 3.289, 95% CI; 2.213\u20134.949, p &lt; 0.001) by 398%, 206.1%, and 229%, respectively, was associated with H. pylori-infected. We recommend the regular monitoring of hematological parameters and eradication of H. pylori infection to minimize the extra-gastric health consequences of H. pylori infection.<\/jats:p>","DOI":"10.3390\/diagnostics13142404","type":"journal-article","created":{"date-parts":[[2023,7,19]],"date-time":"2023-07-19T00:54:01Z","timestamp":1689728041000},"page":"2404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Helicobacter pylori (H. pylori) Infection-Associated Anemia in the Asir Region, Saudi Arabia"],"prefix":"10.3390","volume":"13","author":[{"given":"Omar A.","family":"Al Mutawa","sequence":"first","affiliation":[{"name":"Medical Laboratory Department Southern Region Armed Forces Hospital, Khamis Mushait 62413, Saudi Arabia"},{"name":"Department of Laboratory Medicine, Faculty of Applied Medical Sciences, Al-Baha University, Al-Baha 65528, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Asrar","family":"Izhari","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, Faculty of Applied Medical Sciences, Al-Baha University, Al-Baha 65528, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0247-3824","authenticated-orcid":false,"given":"Raed A.","family":"Alharbi","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, Faculty of Applied Medical Sciences, Al-Baha University, Al-Baha 65528, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulmajeed Abdulghani A.","family":"Sindi","sequence":"additional","affiliation":[{"name":"Department of Basic Medical Sciences, Faculty of Applied Medical Sciences, Al-Baha University, Al-Baha 65528, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdullah M.","family":"Alqarni","sequence":"additional","affiliation":[{"name":"Medical Laboratory Department Southern Region Armed Forces Hospital, Khamis Mushait 62413, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Foton E.","family":"Alotaibi","sequence":"additional","affiliation":[{"name":"Department of Genetic Counseling, Al-Faisal University, Riyadh 11533, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed R.
