Introduction/Objective. Recently published studies have addressed the significant impairment of healthrelated quality of life (HRQoL) in patients suffering from gastroesophageal reflux disease (GERD) and functional dyspepsia (FD). To the best of our knowledge, none of the previously published studies have compared the impact of GERD and FD on HRQoL. The aim of the study was to determine the impact of GERD and FD on HRQoL. Methods. The current sample was extrapolated from a large cross-sectional population-based study conducted in primary health care facilities. Primary care physicians and general internists diagnosed GERD according to the Montreal definition for population-based studies. Also, primary care physicians and general internists diagnosed FD based on the Rome III criteria. The Serbian version of the generic self-administered Center for Disease Control and Prevention questionnaire was used. We used the propensity score method to match GERD and FD samples on variables such as age, gender, education, and adherence to therapy. Results. Regarding self-rated health, similar results were obtained from both groups. The Center for Disease Control and Prevention HRQoL questionnaire version 4 further revealed that functional dyspepsia led to greater disturbances of every-day functioning in regard to the criteria of physically healthy, mentally healthy, and activity limitation days. Conclusion. The results of the study have shown significant impairment of HRQoL in both groups, but, surprisingly, patients with FD experienced more limitations to their every-day functioning compared to patients with GERD.

Background/Aim. Recent population based studies have proved that patients with functional dyspepsia (FD) have a significantly impaired health-related quality of life HRQoL as compared to general population. The aim of the study was to evaluate the impact of FD on (HRQoL) in patients treated in primary healthcare settings in Serbia. Methods. The study involved 1,448 patients with FD. The diagnosis was made by a general practice physician or gastroenterologist using the Rome III diagnostic criteria. The Serbian version of the questionnaire for the assessment of HRQoL of the U.S. Department of Health and Human Services’ Centers for Disease Control and Prevention (HRQoL-4 item CDC) was used for data collection, while descriptive statistical measurements were applied to calculate standard deviation, frequency as well as multiple logistic regression model. Results. Out of the total number of patients, 41.8% assessed their health condition as seriously disordered or poor. The mean values of health disorder duration over the last 30 days was 11.8 days, disordered physical health 7.2 days, mental disorder 6.3 days, and activity limitation 5.1 days. Also, 29.7%, 15.2%, 12.8% and 10.7% of the patients reported ≥ 14 unhealthy days, ≥ 14 physically unhealthy days, ≥ 14 mentally unhealthy days and ≥ 14 activity limitation days, respectively. Conclusion. From patients’ perspective, FD has a significant impact on HRQoL. In this study, 41.8% of the patients described their health status as fair or poor, and FD significantly affects all aspects of life, both mental and physical. The recognition of that impact is probably the most important step towards appropriate treatment and decreasing HRQoL impairment in patients with FD.
