Area of Science:

  • Public Health
  • Epidemiology
  • Maternal Health

Background:

  • Cesarean section rates are a global public health concern.
  • Understanding regional trends and associated factors is crucial for targeted interventions.

Purpose of the Study:

  • To analyze trends in cesarean section proportions in Piauí State, Brazil, from 2000 to 2011.
  • To identify factors associated with cesarean sections in this region.

Main Methods:

  • Time series and cross-sectional study design.
  • Utilized data from the Information System on Live Births (Sinasc) for institutional births.
  • Analyzed data for primiparous women.

Main Results:

  • Cesarean section proportion rose from 34.4% in 2000 to 52.1% in 2011 (APC +4.4%).
  • Factors associated with higher cesarean rates included: maternal age over 40, >12 years of schooling, ≥7 prenatal visits, residing in large municipalities (>300,000 inhabitants), and higher Human Development Index.
  • White-skinned women also showed a higher proportion of cesarean sections.

Conclusions:
