摘      要：Objective: The purpose of this study was to determine the risk factors associated with having H. pylori infection as proven by endoscopic biopsy at Maricopa Medical Center (MMC), a safety-net hospital in phoenix, Arizona which serves primarily patients with limited financial and insurance resources. Methods: A total of 1116 biopsies were identified in a Department of Pathology database searched from November 2004 to March 2013. To be included, the subjects had to have an endoscopy with gastric biopsy. After the inclusion criteria were applied, 282 control subjects without histological evidence of H. pylori infection and 256 cases with histological evidence of H. pylori infection were identified. Patient charts were reviewed to extract information on variables collected for this study. Results: The mean age of cases and controls was 50.5 and 52.3 years respectively. The BMI of the cases and controls was 28.1 and 28.0 respectively. The mean number of upper endoscopic exams performed was 1.3 in cases and 1.4 in controls respectively. Potential predictors examined were gender, history of drug abuse, history of alcohol abuse, chronic pain medication use, smoking, employment status, outpatient vs. inpatient upper endoscopy exam, language spoken (English, Spanish, or bilingual), race/ ethnicity, type of insurance, heart burn, dysphagia, abdominal pain, gastroduodenal ulcers, intestinal metaplasia, and having vs. not having a primary care physician. Based on univariate analyses, having a gastroduodenal ulcer, having a history of abdominal pain, Hispanic race, government insurance status, self-pay insurance status, and speaking Spanish only were found to be significantly related to having H. pylori infection. These variables were next entered into a multivariate analysis. The multivariate analysis revealed that gastroduodenal ulcer, abdominal pain, Hispanic race and self-pay insurance status remained significant predictors of H. pylori infection. For the last 119 subjects, i
