Abstract:
Objective The aim of the present study was to investigate the relationship between the intake of salt and salted food and the infection of Helicobacter pylori (Hp) among 40-69 years old local residents in a county with high gastric cancer risk in Anhui province. Methods From July 2015 to August 2018, we conducted a questionnaire and a serological test for Hp among 40-69 years old local residents in Lujiang county, Anhui province. The questionnaire focused on the consumptions of salt and salted food. The relationship between Hp infection and risk factors was analyzed by gender. Univariate and multivariate logistic regression analysis were used to analyze the relevant influencing factors. Results The Hp infection rate of total local residents was 50.07%. Among male subjects, age, body mass index(BMI), marital status, educational level, job, labor intensity and income had no link to Hp infection (all P>0.05). But among female subjects, BMI was associated with Hp infection ( 2=13.454,P=0.001). Besides, alcohol consumption was a risk factor for Hp infection in male subjects(OR=1.789，95% CI:1.188-2.694，P=0.003). But, high intake of salt and salted food had no effect on Hp infection after adjustment for alcohol consumption variable in men using multivariate analysis (all P>0.05). After adjusted for BMI variable among female individuals, high salt intake (≥9 g/day) (OR=1.462，95% CI:1.060-2.015，P=0.021) and the high salted food intake (≥1 times /day) were risk factors for Hp infection in women(OR=1.560，95% CI:1.021-2.383，P=0.040). Conclusions In one county with high gastric cancer risk in Anhui province, high salt intake (≥9 g/day) and high salted food intake (≥1 times/day) are risk factors for Hp infection among 40-69 years old female local residents.
