Abstract
Introduction
Interpersonal violence is a phenomenon that can occur with different people and conditions. However, people with intellectual disabilities have increased vulnerability to this problem, with potential risks to their health and well-being. The aim of this study was to identify the sociodemographic characteristics of people with disabilities who have been victims of interpersonal violence, the profile of the perpetrators and the measures taken after the victims have been cared for.

Methods
This is an exploratory, descriptive, cross-sectional study using the Interpersonal Violence Notification Forms entered into the Brazilian Ministry of Health’s Notifiable Diseases Information System. The city of São Paulo was chosen as the setting because it is the largest city in Latin America and has a faster data processing system than other cities. The period covered notifications made between 2016 and 2022. The information was collected between October and November 2023 and a univariate statistical analysis was carried out. Fisher’s exact test was used, with a significance level of 5% (α = 0.05).

Results
There were 4,603 notifications against people with intellectual disabilities in the period. The forms of physical violence, neglect/abandonment and psychological/moral violence were more frequent in the 15–19 age group, while sexual violence was more frequent in the 10–14 age group (p < 0.001). The sex most often attacked was female in all the forms investigated (p < 0.001) and the skin colors of the most victimized people were black and/or brown, except in cases of neglect/abandonment (p = 0.058). Most of the victims had little schooling (p = 0.012). The aggressions were committed by one person (p < 0.001), known or related to the victim, such as mother or father, except in cases of sexual violence, where strangers were the main perpetrators (p < 0.001). The sex of the perpetrator was male, except in cases of neglect and/or abandonment (p < 0.001), and the age was between 25 and 29 (p = 0.004). In cases of sexual violence, rape was the most frequent and the procedures carried out were blood collection followed by prophylaxis for Sexually Transmitted Infections (STIs) were the main procedures carried out by health professionals (p = 0.004). The majority of referrals made after receiving care were to the health and social assistance network, with few referrals to bodies such as the human rights reference center, guardianship council and police stations (p < 0.001).

Conclusion
People with intellectual disabilities are highly vulnerable to the forms of violence studied, especially children and adolescents, black or brown, with low levels of education. The perpetrators are usually close people, male and older than the victims. The referrals made by health professionals did not prioritize the victim’s safety and the guarantee of human rights. Lines of care for the health of victims of violence should be implemented, taking into account special aspects, such as people with intellectual disabilities, whose search for help can be difficult.
