Of 327 homosexual and bisexual men participating in an ongoing cohort study pertaining to risk factors for HIV infection who completed a survey regarding history of sexual abuse, 116 (35.5%) reported being sexually abused as children. Those abused were more likely to have more lifetime male partners, to report more childhood stress, to have lied in the past in order to have sex, and to have had unprotected receptive anal intercourse in the past 6 months (odds ratio 2.13; 95% confidence interval 1.15-3.95). Sexual abuse remained a significant predictor of unprotected receptive anal intercourse in a logistic model adjusting for potential confounding variables. en sexually abused as children may experience several sequelae, such as depression, 1 low self-esteem, 2 sexual promiscuity, 3 interpersonal difficulties, 4 or substance abuse, 5 that might increase their risk of engaging in behaviors associated with HIV transmission. However, there has been little research on the effects of sexual abuse on homosexual men, 6 a group particularly at risk of HIV infection. One study of homosexual and bisexual men recruited from sexually transmitted disease clinics found that 37% of the sample had been sexually abused as children, and that childhood sexual abuse was associated with unprotected anal intercourse, substance abuse, depression, reduced social support, and HIV infection. 7,8 This study examined the potential relation between childhood sexual abuse and unsafe sexual behavior in a cohort of homosexual and bisexual men. We hypothesized that sexual abuse would be prevalent in this population, and that there would be a relation between history of childhood sexual abuse and HIV-related sexual risk taking.
METHODS
ParticipantsParticipants were homosexual and bisexual men participating in two studies examining factors related to HIV infection at a community health center. 9,10 There were no significant demographic differences between the two studies, and there were similar proportions engaging in unprotected anal intercourse at study entry. Of 422 cohort members, 359 were eligible to participate. Of these, 327 (91.1%) completed the questionnaire.
PROCEDUREAt a regular study visit, participants were interviewed about sexual and health behaviors, were tested for HIV, then completed the sexual abuse questionnaire. Appropriate measures were taken to help participants cope with distressing reactions to the questionnaire.
Childhood Sexual Abuse Measure Childhood StressParticipants were asked to rate how stressful their childhood was, from 1 (not at all stressful) to 7 (extremely stressful).
Definition of Sexual AbuseParticipants were presented with Finkelhor's community standard definition: sexual abuse is a sexual experience with a person at least 5 years older if the child was 12 and under, or 10 years or older if the child is between 13 and 16 inclusive, with or without physical contact, and whether or not sex was wanted by the child. 11
