Factors associated with reporting delays and severity of childhood sexual abuse in São Paulo, Brazil.

Negative health outcome and its relationship with length and severity of Childhood Sexual Abuse is well established in the literature. Until recently, this literature consisted disproportionately of studies of adults recalling past events. For guidelines for the treatment of childhood survivors, research focused on child victims may be more relevant. We aim to characterize factors related to long-term and severe sexual abuse among children in São Paulo, Brazil. We conducted a cross-sectional study of children up to the age of ten, referred to a specialty program on sexual abuse between 2004 and 2013. Length and severity of the abuse were tested for associations with variables related to the abuse using a Chi-square test, followed by the Poisson regression with robust variance for prevalence ratio. Most children experienced abuse were reliant on relatives or friends for housing (45%). The time between abuse and reporting was longer when the perpetrator lived in the same household as the child and when abuse was reported by a relative or friend. Abuse was more frequent among female children, but longer and more severe in males. A lack of independent housing, parents' education and social stigma facilitated childhood sexual abuse by delaying reporting among our sample.
