OBJECTIVES: The frequency of caesarean section alters worldwide and shows great varieties and spatial differences in countries with developed health system by various health service providers. This study investigates caesarean section's frequency and distribution by health service providers. METHODS: Data of National Health Insurance Fund (NHIF) of Hungary and Hungarian Central Statistical Office were processed. Analyzes covers the period of 1960-2013. We calculated the rate of cesarean section within the total number of deliveries. RESULTS: Based on the comprehensive analysis of statistical data, the ratio of caesarean section in Hungary rose from 2,5% to 37% in the investigated period. There is a tenfold difference among health service provider institutions. (9%-97%) The increased number of caesarean section is obviously connected to the increased ratio of primer caesarean section and the decreased number of spontaneous delivery after caesarean section. A number of studies have justified that reaching the optimal ratio is a health and social challenge. 2,5% of Hungarian deliveries ended up in caesarean section in 1960, 7% in the '70s. However, its frequency increased to 10% in the '90s, 20% in 2000, 28.9% in 2006, and by today, it has overstepped 37%. Via analyzing distribution according to health service providers, extraordinary differences prevail. NHIF's data show that the ration of caesarean section between 2000 and 2013 varied from 9% to 97%, i.e., almost a tenfold difference exists among various providers.  CONCLUSIONS:   Determined steps need to be regarding professional and financing areas in order to decrease differences. The efficiency of parental care and the identification of high-risk expectants need to be improved, financing interest has to be established during patient care in hospitals and via shedding light to statistical data, transparency of professional activity has to be established.
