from Southern Iran who were 25 years of age or older. Participants completed a questionnaire that consisted of demographic factors, lifestyle data, gastrointestinal symptoms, and the Short-Form 36 Health Survey [SF-36] questionnaire. There was a 48% prevalence of dyspepsia symptoms among participants. The prevalence was higher among females, those less than 35 years of age, married participants, and those with a low body mass index [BMI] . The correlation between dyspepsia and quality of life was significant. Dyspeptic patients were classified into ulcer-like [27.9%] , dysmotility-like [26.2%] , and unspecified [45.9%] groups. A significant correlation existed between dyspepsia symptoms and consumption of dairy products, drinking water and tea before and after meals, smoking, dysphagia, reflux, heartburn, and use of non-steroid anti-inflammatory drugs and acetaminophen. The high prevalence of dyspepsia in Qashqai nomads necessitates educational health programs for the migrating tribes in order to decrease prevalence of this disease
