Abstract
Helicobacter pylori (H pylori) infection was common worldwide and previous researches on the correlation between H pylori infection and metabolic abnormality provided inconsistent conclusions. We assessed acute H pylori infection prevalence and the relationship with metabolic abnormality in general Chinese population. Participants attending for the physical examination underwent a carbon-13 urea breath test. For individual, the following data were collected: age, gender, body mass index (BMI), systolic blood pressure, diastolic blood pressure, total protein, albumin, globulin (GLB), total bilirubin, direct bilirubin (DBIL), indirect bilirubin, alanine transaminase, glutamyl transpeptidase, alkaline phosphatase, cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, urea nitrogen, creatinine, uric acid, fasting plasma glucose (FPG), and homocysteine. A total of 29,154 participants were enrolled. The prevalence of acute H pylori infection was 29.79% (8684/29,154). Spearson correlation analysis showed that gender, BMI, ALB, GLB, total bilirubin, DBIL, indirect bilirubin, and FPG were closely related to H pylori infection. Multinomial logistic regressions analysis with stepwise subset selection further identified gender, BMI, ALB, GLB, DBIL, and FPG as independent risk factors for acute H pylori infection. Our results indicated that acute H pylori infection might has a significant impact on metabolic abnormalities, which should be further confirmed.
