Childhood sexual abuse, gay-related victimization, and syndemic production among men who have sex with men (MSM): Findings from the Multicenter AIDS Cohort Study Sin How Lim, Amy Herrick, Thomas Guadamuz, Mark Friedman, Michael Marshal, Ron Stall Department of Behavioral and Community Health Sciences
Key Finding In MSM, sexual violence and social shaming in early life are associated with psychosocial health problems in later life
Syndemic “two or more afflictions, interacting synergistically, contributing to excess burden of disease in a population”-- Centers for Disease Control and Prevention, USA. www.cdc.gov/syndemics
Background • Psychosocial epidemics of substance use, depression, intimate partner violence, are associated with HIV risk taking among urban MSM (Greenwood 2002, Paul 2002, Stall 2003, Mills 2004, Relf 2004) • Syndemic Theory (Stall 2008) • Cultural marginalization (Singers 1994, Myers 2003, Diaz 2001) • Homophobia • Stigma • Life-course perspective
Aim of Study To test part of the syndemic theory using empirical data from a prospective cohort study of MSM
Multicenter AIDS Cohort Study • A prospective, cohort study of HIV infection and risk factors among MSM • Analytic sample, n=1086 • Baltimore/Washington DC, Chicago, Los Angeles, and Pittsburgh • New set of measures between 2007-2008
Measures Childhood Sexual Abuse Gay-related Victimization (28.4%, age 12-14) Sense of Masculinity Failure Internalized Homophobia Current Gay-related Discrimination Current Stress
Syndemic Variables • Sexual Compulsivity- inability to control sexual urges, feelings, fantasy, etc • Intimate Partner Violence - physical, emotional, sexual violence • Depression - CES-D (Raldoff, et al. 1977), depressive symptoms in past week • Substance Use - poppers, crack cocaine, other forms of cocaine, methamphetamines, ecstasy, and binge drinking • Risky Sexual Behavior - Number of unprotected anal intercourse partners in past 6 months
Statistical Method Path analysis (EQS 6.1, Bentler) was conducted to test a model (N=1086) containing • childhood sexual abuse, gay-related victimization, sense of masculinity failure • discrimination, internalized homophobia, stress, sexual compulsivity • syndemic variables

Discussion • Gay-related victimization is common in young gay men • Childhood sexual abuse, Sense of masculinity failure -> Sexual Compulsivity -> Substance use -> NUAI • Early Sense of Masculinity Failure -> Depression • Violence, discrimination occur in gay youth • Internalized by gay youth • shame
Implications • Prevention: life course perspective, early life Structural intervention to reduce gender norm-based violence Effective interventions need to address multiple interrelated psychological and sexual sequelae • Future research: longitudinal study of heterosexual and homosexual adolescents • Subpopulations: racial minority, rural

Measures • Childhood Sexual Abuse • forced sex • before 18 years old • moderately or extremely upsetting experience • prevalence 9.3% • Gay-related Victimization • age 12-14 • verbal insults • threatened with physical violence • targets of thrown objects • physical assault (punched/kicked/beaten) • threatened by knife, gun, or weapon • Any victimization, prevalence 28.4%.
Measures • Sense of Masculinity Failure • 15-18 years old • Experience of shame related to not achieving masculine norms (Andrew 2002) • e.g.,“How often do you feel ashamed about your ability to act like a man” • Internalized Homophobia • In the past 12 months • 5-point response scale (disagree strongly to agree strongly) • e.g., “I tried to stop being attracted to men in general”
Measures • Current Discrimination -past 12 months-verbally insulted, or threatened physically, targeted with a thrown object, punched/kicked/beaten, or threatened with a knife/weapon because respondent was gay or bisexual • Current Stress -past 12 months-finances, job satisfaction, death/illness/injury of close ones, housing, physical health • Sexual Compulsivity-past 5 years-condition characterized by sexual fantasies and behaviors that interfere with personal, interpersonal, or vocational pursuit “I had trouble controlling my sexual urges”
Strengths and Limitations • Measures have shown fairly good psychometric properties and thus path analysis is appropriate • Could examine moderator and interaction effects • Childhood adverse experience are retrospective • May only be generalized to urban MSM in the United States
