The impact of diet, exercise, and sleep on Helicobacter pylori infection with different occupations: a cross-sectional study.

ABSTRACT

BACKGROUND: Associations between Helicobacter pylori infection and lifestyle factors vary greatly by geographic location. This study aims to evaluate the prevalence of Helicobacter pylori infection in the Hunan cohort of central China and analyze the associations between Helicobacter pylori infection and lifestyle factors in different occupations. METHODS: This was a cross-sectional study. Participants who received an annual physical examination were invited. Helicobacter pylori infection was detected by the 13 C-urea breath test. Self-reported physical examination questionnaires were used to analyze participants' demographic information, diet, exercise status, and sleep situations. RESULTS: 23254 participants finished this study. The Helicobacter pylori infection rate in the Hunan area was 25.8%, with the lowest prevalence in students (8.5%) and the highest prevalence in business managers (29.9%). The risk factors for Helicobacter pylori infection were marital status (divorced or married) (OR1.16, 95%CI1.090-1.234), overeating (OR1.105, 95%CI 1.001-1.220), and consumption of eggs (OR1.047, 95%CI1.004-1.092), animal viscera (OR 1.077, 95%CI1.014-1.144) and coffee (OR1.074, 95%CI1.019-1.132). Participants' education level (OR0.911, 95%CI0.881-0942), consumption of midnight snack (OR0.926, 95%CI0.877-0.977), and vegetable (OR0.927, 95%CI 0.884-0.972) were protective factors against Helicobacter pylori infection. Whether participants exercised regularly or had sleep problems had no significant effect on Helicobacter pylori infection. Different professionals showed significant differences in the rates of overeating, eating three meals on time, midnight snack, and consuming coffee, eggs, animal viscera, and vegetables > 3 times/week (P values < 0.05). CONCLUSIONS: Helicobacter pylori infection showed a significant relationship with dietary factors, but not significantly with sleep and exercise factors. Different occupations showed different dietary tendencies related to Helicobacter pylori infection. The design of an occupation-based Helicobacter pylori screening and prevention program is supported.
