Overview

Longitudinal ecological study reveals regional disparities and trends in breast cancer mortality in Argentina, indicating the need for targeted efforts.

Key Points

  • This research aims to analyze the spatiotemporal patterns and regional inequalities of breast cancer mortality in Argentina from 1991 to 2023.
  • Conducted a longitudinal ecological study using death certificates for breast cancer from 1991 to 2023.
  • Estimated crude and age-standardised mortality rates (ASMR) per 100,000 women, stratified by age groups.
  • Performed spatial analyses using Moran's Index and temporal assessments with Joinpoint regression.
  • Nationally recorded 165,251 breast cancer deaths with a crude rate of 25.87 per 100,000 (95% CI: 25.75–25.99).
  • ASMR for women <45 years was 3.14 (95% CI: 3.09–3.19) and for women ≥45 years was 67.98 (95% CI: 67.63–68.33).
  • Geographical disparities observed with higher ASMR in Cuyo (23.62) and Center (22.07) regions, while the Northwest had the lowest (16.58).
