Introduction: Recent studies found that Helicobacter pylori (H. pylori) infection plays a role in cardiometabolic disorders. The objective of this study was to assess the association between H. pylori infection and overweight or obesity in a Chinese population. @@@ Methodology: A cross-sectional analysis using data from the subjects who underwent a health examination between January 2010 and June 2012 in the department of comprehensive medicine was performed. Diagnosis of H. pylori infection was achieved using the carbon urea breath test (C-14-UBT). The participants were divided into H. pylori infection-positive group and H. pylori infection-negative group by C-14-UBT. @@@ Results: A total of 2,050 subjects were enrolled in the study. The H. pylori infection-positive group had significantly higher body mass index (BMI) levels than did the H. pylori infection-negative group (25.32 vs 24.95, p = 0.008). There was a positive association between H. pylori infection and BMI levels (beta = 0.30 +/- 0.12, p = 0.015). After additional adjustment for white blood cell count (WBCC), the statistical significance disappeared (beta = 0.24 +/- 0.12, p = 0.053). Furthermore, a positive association between H. pylori infection and overweight/obesity according to different BMI criteria (BMI = 24, BMI = 23) was found. However, the association between H. pylori infection and obesity was consistently significant only based on the Asian criteria (BMI >= 27.5), but not significant based on the Chinese criteria (BMI = 28). @@@ Conclusion: H. pylori infection was significantly and positively associated with overweight/obesity in a Chinese population.
