The aim of this study was to determine the differences in functional disorders of the digestive system in a sample of health professionals who have completed university education (college, group VŠ) and the ones who have completed secondary school (group SŠ). It is presumed that the examinees that have completed university education have more functional disorders such as dyspepsia and IBS. Patients and methods. 105 anonymous questionnaires were distributed to the health professionals employed at the health centre Đakovo. Demographic data, the incidence of dyspepsia, incidence of irritable bowel syndrome (IBS) and morphological characteristics of faeces were registered. The data were processed using the statistical programme SPSS. T-test, 2 test or Fisher's exact were used for comparison. P < 0,05 was considered to be a statistically significant level. Results. Among the total number of the examinees, 47 have completed university education, while 52 have completed secondary school. The average age of the examines that have completed secondary school was 48,0 (SD 12,1) and 50,4 (SD 9,0) for the ones that have completed university education. The examinees who have completed university education are on average less satisfied with their material status (P = 0,0025) and quality of life when compared to the ones having completed secondary school (0,048). Among the examinees with completed secondary school there is a higher number of smokers, and the incidence of smoking in the family is higher (32/52 as opposed to 14/47 among examinees with completed university education, P = 0,002). The incidence of gastritis or stomach ulcer is higher in the group of examinees with university education (11/47 as opposed to 3/52, P = 0,019). The discomfort and abdominal pain are more often in the group of examinees with secondary education (P = 0,011), while the incidence of other symptoms that were tested was the same for both groups. Conclusion. Although significant differences had been found in the way they perceive their own socioeconomic status, the incidence of smoking, hypertension and gastritis, the study has not confirmed differences in incidence of irritable bowel syndrome among the population of health professionals having completed secondary school and the ones having completed university education. It is necessary to carry out a more extensive study containing targeted inquiries in order to confirm the difference among the mentioned samples.
