Rape crimes: detailed analysis of all cases that occurred in the Brazilian Federal District in 2018-2019.

The study aimed to describe the victim's sociodemographic characteristics and the circumstances in all rape crimes in 2018 and 2019 in the Brazilian Federal District (BFD), comparing cases when the offender was known and unknown to the victim to identify high-risk situations. A population-based, observational, cross-sectional study was performed with rape collected by the local police. The log-binomial regression model was used to compare groups with/without victim-author relationships; variables with more than two categories were analyzed using the chi-square test. A 5% significance level was adopted. There were 1,681 cases analyzed. The results showed that rape occurred more often on weekends, in the evening, and in the BFD's most socioeconomic and educational vulnerable region. In the cases of offender victims' relationships, crimes occurred in residences, children/adolescents were the victims, with elementary school education, and the presence of libidinous acts (no penetration) was greater. When there was no victim-author relationship, the threat and physical violence as approach strategies and the use of alcohol/drugs were more common; adults are the largest proportion of these victims.
