INTRODUCTION:

The aim was to determine the cesarean section rate in women giving birth between 2000 and 2020 in Neuquén province, seeking for differences between sub-sectors, health zones, cities and health institutions .

METHODS:

Statistics from the Perinatal Information System were analyzed regarding type of delivery, newborns and women delivering between 2000 and 2020. A stratified analysis of the cesarean section rate was conducted, describing central tendency and dispersion measures, and the average annual rate of increase .

RESULTS:

Maternal sociodemographic characteristics have changed, with adolescent pregnancy decrease and a higher number of mothers older than 35 years of age. The percentage of low birth weight was higher in the private sub-sector, with a significant decrease of gross birth rate, mainly inside the province. There was a steady increase as well as growing and very significant differences between sub-sectors (and within them between the different institutions) .

DISCUSSION:

The results show very significant differences when comparing sub-sectors and institutions regarding cesarean birth, and contribute to building policies tailored to the epidemiological situation of the province and each health institution.
