Abstract Background Roma ethnic minority in Slovenia was recognized as a vulnerable group with worse health indicators and significantly shorter life expectancy. The vast majority of Roma population in Slovenia have health insurance. We were investigating the use of hospital services in Roma population according to their age and comparing it with the rest of the population. Methods We determined the inhabitants of Roma settlements from the Slovenian register on residents. The data on hospital treatments used were from Slovenian national register on hospital treatments for the period 2018 to 2022. We compared different ratios according to certain hospital treatments within age categories of patients and co-pared those two groups. The frequency statistics, ANOVA and comparison of column proportion tests were used (p-value<0.005, 95% CI). Results Inhabitants of Roma settlements were more often treating in hospitals that rest of population. If comparing the frequency of hospital treatments between age groups only in Roma population, the percentage of hospital treatments steeply declines with age as well as the number of persons in age groups. The highest percentages and numbers of services are in the youngest age group of 0-15 years, and the lowest in the oldest group (75+). Therefore, significantly higher ratios of hospital treatments were detected in younger then in older age groups. Conclusions Roma children and youngsters (0-15 years old) had the highest rate of hospital treatments and it declined with the age. It was consistent with age pyramid of Roma as young population as well as emphasized care for children in culture. The steady decline rate of hospital treatments with age could be explain with delayed seeking of health care services in adult age and higher premature mortality that leads to smaller adult population. Additional and in-depth research is necessary to explain the root causes of higher premature mortality and use of primary and preventive health services. Key messages • Higher use of hospital treatments was caused by higher morbidity. It is necessary to explore the leading causes of hospital treatments and premature mortality. • It is necessary to explore the use of primary health care service, preventive service and level of health literacy of inhabitants of Roma settlements.
