Objectives: Polycystic ovary syndrome (PCOS) is a highly prevalent disorder, representing the single most common endocrine-metabolic disorder in reproductive-aged women. The aim of our study was to determine the epidemiological disease burden of polycystic ovary syndrome in Hungary.

Methods: Data were derived from the financial database of the Hungarian National Health Insurance Fund Administration (NHIFA), for the year 2019. Database included annual number of patients number of cases and the prevalence of the utilization according to age groups in 100,000 inhabitants. The following health insurance treatment categories were included into our study: general practice care, home care, in- and outpatient care, medical imaging, laboratory diagnostics, pharmaceuticals and medical aids. Patients with polycystic ovary syndrome were identified with the following code of the International Classification of Diseases 10^th revision: E2820.

Results: The highest number of patients was in the outpatient care (12,832 women), followed by general practice care (6,876 women), and laboratory diagnostics (4,287 women). The mean age of the patients was 29.3 years in outpatient care. Based on the number of patients related to the outpatient care the prevalence was 251.3 among 100,000 women. Additionally the age specific prevalence per 100,000 women was the highest within age group of 20-29 years (1,137.2 women) and 30-39 years (579.1 women).

Conclusions: The results showed that the highest number of patients was in outpatient care in 2019. The prevalence of endometriosis showed significant differences by age groups. The most affected age group was women aged 20-29, which was 6.1 times higher than number of patient of 40-49 years age group.Thus the early diagnosis and medical interventions are important as the disease can significantly reduce a patient's quality of life and decrease the success of childbearing.
