  2. Background: Epidemiology of STDs and HIV in Massachusetts • Similar to national trends, Massachusetts men who have sex with men (MSM) continue to be at increased risk for STDs, including HIV. • Massachusetts trends: • MSM accounted for the majority of infectious syphilis cases, ranging from 68% in 2001 to 72% in 2005. • A 32-fold increase in Quinolone-resistant Neisseria gonorrhoeae (QRNG) was observed among MSM (two cases in 2001 and 66 cases in 2005). • Among males, the proportion of HIV cases with MSM exposure increased from 41% in 1999 to 54% in 2005.

  3. Background: Psychosocial problems and sexual risk • Several studies have documented the association of psychosocial problems with sexual risk-taking among MSM. • Studies have found a relationship between: • Stressful or traumatic life events (incl. childhood sexual abuse, sexual coercion in adulthood, domestic violence, witnessing the death or physical harm of another person, etc.). • Sexual risk-taking. • Limitations of prior research: • Focused on the objective occurrence of stressful or traumatic events and their effects, but not on a person’s emotional reaction to the events. • Effects have been generally in the modest range.

  4. Specific Aims • The current study assessed psychosocial and behavioral associations of STD and HIV risk behavior among a cohort of Massachusetts MSM screening in for a significant emotional response to a stressful or traumatic life event (i.e., screening in for symptoms of PTSD). • We hypothesized that it is not the event itself, but one’s emotional response to it that may differentiate MSM who engage in HIV/STD risk behavior from those who do not.

  5. Methods Participants and Procedures • Between March 2006 and May 2007, 189 participants completed a quantitative survey (approx 1 hour in duration). • Participants were eligible if they were: • 18 years of age or older. • A Massachusetts resident. • Self-reported having sex with men. • Recruitment: • Convenience sample (n = 63). • Modified RDS sample (n = 126). • All study measures and procedures were IRB-approved by The Fenway Institute. • Supported by the Massachusetts Department of Public Health.

  6. Methods Predictors of Interest • Experiencing a worst event • Asked participants an open-ended question about worst event ever experienced. • Responses were dichotomized. • Significant emotional response to a worst event • SPAN (Startle, Physiological arousal, Anger, and Numbness) (Meltzer-Brody et al., 1999). • Score 6 or greater indicated a significant emotional reaction to the worst event (i.e., PTSD symptomatology).

  7. Methods Outcome Variables • Unprotected anal sex (either insertive or receptive) in the past 12 months. • CES-D: Center for Epidemiologic Studies Depression Scale (DHHS, 2004; Hann et al., 1999; Radloff, 1977). • SPIN: Symptoms of social anxiety (psychometric properties of the Social Phobia Inventory) (Connor et al., 2000). • CAGE: Screening instrument for alcoholism (Ewing, 1984; Knowlton et al., 1994; Mayfield et al., 1974).

  8. Methods • Data analysis • SAS version 9.1 (Cary, NC) statistical software; statistical significance at the p<0.05 level. • Comparisons between MSM screening in for a significant emotional response (SPAN 6+) and those not screening in (SPAN 0-5). • Descriptive statistics,Chi-square and t-test statistics. • Bivariate and multivariable logistic regression. • Variables that were statistically significant in bivariate regression analyses were retained in final multivariable logistic regression models. • Controlled for race, sexual orientation, and HIV status.

  9. Results: Demographics Race/Ethnicity: Sexual Orientation:

  10. Results: Demographic comparisons • 93% of the sample (n=176) reported having experienced a worst event. • 60% of the sample (n=113) screened in for a significant emotional response to a stressful or traumatic life event (PTSD symptomatology, SPAN score 6+). • Men screening in for a significant emotional response were more likely to: • Be white (OR=1.93; p<0.03). • Be gay-identified (OR=2.01; p<0.03).

  11. Results: Reported worst event

  12. Results: Risk behavior in past 12 months Substance use during sex in past 12 months

  13. Results: Significant emotional response in relation to unprotected anal sex in past 12 months

  14. Results: Significant emotional response in relation to depression and social anxiety

  15. Limitations • Emotional response to a stressful or traumatic life event was assessed using a PTSD screener (e.g., did not measure intensity of more remote events, or duration or frequency of events). • Data is constrained by methodological difficulties present in most stressful life event research (namely inconsistencies conceptualizing and measuring stressful/traumatic events). • RDS led to diverse sample but incentives may have resulted in more socially marginalized group of MSM (i.e., prevalence of stressful/traumatic events may not be generalizable across all MSM). • Since one third of participants were patients at Fenway, a community health center specializing in LGBT healthcare, the sample may be more gay-identified with a higher prevalence of HIV infection/STD history than the greater Boston area MSM population.

  16. Discussion • Experiencing a stressful or traumatic life event did not in and of itself predict increased sexual risk-taking or co-morbid psychosocial health problems. • However, currently having a significant emotional response to a stressful or traumatic life event (PTSD symptomatology) did predict unprotected anal sex in the past 12 months, depression, and social anxiety. • Findings suggest that having a significant emotional response to a stressful or traumatic life event is predictive of sexual risk-taking over and above the effects of the event itself. • The current study can be placed in the context of other research documenting elevated rates of co-occurring psychosocial issues facing high-risk MSM. • Potential benefit of incorporating how to cope with these issues in HIV prevention and care interventions.
