Summary

This summary is machine-generated.

Sexual violence against children and adolescents in Southern Brazil shows an upward trend, particularly in border municipalities. While pandemic timing had little effect on overall rates, spatial patterns shifted, highlighting the need for targeted protection policies.

Area Of Science

  • Public Health
  • Epidemiology
  • Child Protection

Background

  • Sexual violence against children and adolescents is a significant public health issue.
  • Understanding its spatial distribution is crucial for effective intervention.
  • The COVID-19 pandemic may have impacted reporting and incidence patterns.

Purpose Of The Study

  • To analyze the spatial distribution of child and adolescent sexual violence in Southern Brazil.
  • To compare incidence rates between border and non-border municipalities.
  • To assess changes in distribution related to the pre- and post-COVID-19 pandemic periods.

Main Methods

  • Ecological study utilizing spatial analysis.
  • Data sourced from the Notifiable Diseases Information System (SINAN) from January 2017 to December 2022.
  • Analysis included case counts, trends, sex differences, and geographical comparisons.

Main Results

  • A total of 39,751 cases were identified, demonstrating an overall upward trend.
  • Paraná, Rio Grande do Sul, and Santa Catarina had the highest case numbers.
  • Border municipalities exhibited higher average rates of sexual violence compared to non-border areas.

Conclusions

  • Sexual violence against children and adolescents in Southern Brazil is increasing.
  • Border regions present a higher risk, necessitating focused public health strategies.
  • Urgent, targeted policies are required to protect vulnerable populations.
