Aim of the research is to establish the prevalence of dyspepsia in Osječko-baranjska County, to establish its specific characteristics and to determine the effect of demographic, anthropometric, and socioeconomic factors. It is a cross-sectional and case control study conducted in 2010 on systematic sample of 900 subjects between 20 and 69 years of age. Every subject was sent an invitation letter and a Rome III diagnostic questionnaire for one of the disorders. A scoring algorithm was used to confirm or exclude the diagnosis of functional dyspepsia (FD). The chi-square test, t-test and logistic regression were used for analysis.
Prevalence of dyspepsia was recorded in 16, 56 %, of subjects. There is no statistically significant difference in prevalence of dyspepsia male and female. The prevalence of dyspepsia increases with age. Correlation with the place of birth was proven. There is no correlation between the current place of residence (rural area and town) and dyspepsia. There is a correlation with marital status. Correlation between stool forms was proven. There were a greater number of subjects that had at least one alarm symptom or some of the psychosocial factors and they often suffered from a chronic disease. The risk for dyspepsia increases with age, body mass index (BMI), and poorer health. Logistic regression showed the following as statistically significant for dyspepsia: place of birth and self-assessment of one’s health. FD presents a significant health problem. Rome III survey questionnaire proved to be an acceptable method for diagnosing this functional disorder in clinical-consilliary and primary health care for persons showing signs of alarm and needing further diagnostic treatment.
