Correlation between Helicobacter Pylori infection and abdominal obesity / 中华全科医师杂志

ABSTRACT

Objective:To investigate the correlation between Helicobacter Pylori (HP) infection and abdominal obesity. Methods:A total of 1728 subjects who underwent routine health check-up and 13C or 14C urea breath test at the Health Management Center of Beijing Hospital from January 2018 to December 2018 were enrolled. The correlation between HP infection and metabolic syndrome (MS) components was analyzed. Results:There was no significant difference in HP infection rate between MS group and non-MS group [73.3%(360/491) vs. 68.7%(850/1 237), χ2=3.55, P=0.060]. The prevalence of abdominal obesity and elevated fasting blood glucose in HP positive subjects was significantly higher than that in HP negative subjects [71.7%(352/491) vs. 65.4%(809/1 237),χ2=6.36, P=0.042;80.7%(396/491) vs. 75.9%(939/1 237),χ2=4.50, P=0.034]. The non-obesity rate of HP positive subjects [28.1%(138/491)] was lower than that of HP negative subjects [34.3%(424/1 237), χ2=6.36, P=0.042). There were no significant differences in rates of hypertension, high triglyceride and low HDL-C, increased total cholesterol, increased LDL-C between HP-positive and HP-negative subjects (all P>0.05).There was no significant difference in HP positive rate between MS and non-MS groups [29.8%(360/1 210) vs. 25.3%(131/518), χ2=3.55, P=0.060]. The HP positive rate in subjects with abdominal obesity was higher than that with normal abdominal circumference [30.3%(352/1 161) vs. 24.5%(139/567), χ2=6.31, P=0.012], and the HP positive rate in subjects with elevated fasting blood glucose (FBG) was higher than that with normal FBG [29.7%(396/1 335) vs. 24.2%(95/393), χ2=4.50, P=0.034]. The HP infection rate was not associated with hypertension, hypertriglyceridemia and low HDL-C. Logistic regression analysis showed that abdominal obesity ( OR=1.327, P=0.016) was the risk factor of HP infection; and HP infection was the risk factor of abdominal obesity ( OR=1.277, P=0.043). Conclusion:HP infection is positively correlated with abdominal obesity and may be correlated with elevated fasting blood glucose, but not with other components of metabolic syndrome in health check-up population.
