Dyspepsia is a common complaint among patients who refer to gastroenterology clinics. Studies have shown that there is a strong relationship between dyspepsia and Helicobacter pylori (HP) infection. We have investigated the prevalence of HP infection in patients with dyspepsia and its correlation with age and socioeconomic status (SES) of patients in Mazandaran province, northern Iran.


In this cross-sectional study, patients with dyspepsia who had undergone upper gastrointestinal endoscopy were enrolled. Diagnosis of HP infection was according to the results of rapid urease test (RUT), and Giemsa staining of pathology samples. A questionnaire including endoscopic findings, demographic data, and SES information was completed for each patient.


The mean age of the 614 patients was 45.8±5 years, and 60% of them were female. Most patients had normal endoscopy (56.1%), and gastric ulcer and erosion was the most common abnormal endoscopic finding (24.7%). The prevalence of HP infection in patients with dyspepsia was about 66.6%. HP infection was associated with a lower prevalence in people aged below 30 years and good SES.


The prevalence of HP infection in patients with dyspepsia was 66.6%. In addition, HP infection rate was lower in people under the age of 30 years and patients with good SES.
