Abstract
OBJECTIVE: To investigate the prevalence of early childhood maltreatment and associations with later sexual behavior among adult substance users. METHODS: A cross-sectional study enrolled 134 substance dependents who sought outpatient care in São Paulo, Brazil. Childhood trauma prevalence was assessed using the Childhood Trauma Questionnaire (CTQ). The Sexual Addiction Screening Test (SAST), drug of choice (DOC), and sexual behavior were also investigated. RESULTS: The sample was composed predominantly of single adult males (76.1%), with alcohol as the DOC (73.9%). Experiences of emotional neglect (88.1%), emotional abuse (80.6%), physical neglect (78.4%), physical abuse (64.2%), and sexual abuse (31.3%) were prevalent. Women were more likely to have been sexually abused (OR 2.9, 95%CI 1.15-7.61) and physically abused (OR 3.7, 95%CI 1.31-10.6) in childhood. Those who were sexually abused in adulthood were more likely to have suffered physical abuse in childhood (OR 6.9, 95%CI 1.45-11.8). The odds of having been sexually abused in childhood were higher among subjects who reported to have exchanged sexual favors for drugs (OR 5.7, 95%CI 1.35-9.64) and to have been sexually abused in adulthood (OR 6.1, 95%CI 5.2-12.36). CONCLUSION: Physical and sexual abuse in childhood are highly prevalent in substance-dependent adults, and are associated with sexual revictimization and high-risk sexual behavior in adulthood.
