HIV/AIDS and African Americans • President Obama announced plans to concentrate HIV prevention efforts on the highest-risk populations, including gay and bisexual men and African Americans • African Americans represent only 12% of the US population, but 45% of new HIV infections in 2006 • Rates of new infections were 7 times higher among African Americans than White Americans • Heterosexual exposure is the most common HIV transmission category for African American women and second most common for African American men
HIV serodiscordant couples • Years of HIV/STD risk reduction research teach that sexual behavior change is not easy, but hard • But to change the sexual behavior of people in long-term relationships is singularly hard • Habit, trust and suspicion make it unlikely partners would even bring up the idea of condom use • Yet it is especially important to promote safer sex practices in a serodiscordant couple • An uninfected person is regularly having sex with an infected person—what an efficient way to spread HIV
Objectives • Examine the efficacy of an HIV/STD risk reduction intervention for African American HIV serodiscordant heterosexual couples: • Does it increase condom use? • Does it reduce the incidence of STDs? • Why is it effective or ineffective? • Is it more effective with certain couples or individuals?
Design • Multisite Cluster-Randomized Controlled Trial • Groups (the cluster) of 3 to 5 couples were randomized • HIV/STD Prevention vs. Health Control Interventions • Four clinical sites • Atlanta, Georgia • Los Angeles, California • Philadelphia, Pennsylvania • New York City, New York • Assessments before, immediately after, and 6 and 12 months after the intervention
Key eligibility criteria • At least 1 partner is African American • A couple for at least 6 months • Plan to remain a couple at least 12 months • At least 18 years of age • One HIV+ and one HIV- • Aware of each other’s HIV status • At least one reported unprotected sex with partner in prior 90 days • No severe physical or sexual abuse in the past year
Structure of Interventions • 8 weekly 2-hour sessions • 4 couples sessions and 4 group sessions • 3 to 5 couples per group • Activities included discussions, interactive exercises, role-playing, videos, and games • African American male and female co-facilitators
Eban HIV/STD risk reduction intervention • Eban is African concept of “fence” - symbol of safety, security, and love within a family • Couple-focused intervention • Theoretical Framework • Social Cognitive Theory • Ecological Theory • Afrocentric Paradigm
Social Cognitive Theory • Albert Bandura • Self-efficacy • Outcome expectancies • Behavioral skills • Practice • Observational learning
Ecological Model • UrieBronfenbrenner • Integrates multiple levels of analysis • Ontogenic factors (individual level) • Microsystem factors (couples level) • Exosystem factors (community level)
Afrocentric Paradigm: Nguzo Saba (The 7 Principles of Kwanzaa) • MaulanaKarenga • Unity • Self-determination • Collective work and responsibility • Cooperative economics • Purpose • Creativity • Faith
Eban HIV/STD risk-reduction intervention (continued) • Couples-focused intervention to enhance: • Beliefs favorable to condom use • Skill and self-efficacy to use condoms • Couples’ communication regarding HIV/STD risk reduction • Peer norms for condom use • The couple’s relationship
Eban HIV/STD Intervention Activities Date Night Wheel of Relationship Issues Couple Connection Coupons Safer Sex Jeopardy • Talk and Listen • FENCE • Cherish Activity • Eban Café • Condom-ments
FENCE—Address problem-solving skills • Find out what is going on • Explore each other’s feelings • Name and discuss options • Choose the best option to solve the problem • Execute the plan and monitor progress
Health Promotion Comparison Intervention • Social cognitive theory • Not couple-focused • Individual-focused intervention designed to: • Increase fruit and vegetable consumption • Reduce fat consumption • Increase physical activity • Increase cancer screening behaviors • Decrease excessive alcohol consumption
Self-report outcomes • Audio computer-assisted self-interviewing (ACASI) • Proportion condom-protected intercourse in prior 3 months • Number of unprotected intercourse acts • Consistent condom use • Concurrent partners • Theory-based mediators of condom use • Health behaviors and mediator variables
Biological outcome • Urine samples from men • Vaginal swabs from women • Nucleic acid amplification tests for • Chlamydia • Gonorrhea • Trichomonas • STD positive is positive test for any of the 3 STDs
Health Promotion (8 weeks) Screen, confirm eligibility, and collect baseline data Follow-up: IPT, 6m, 12m Randomize HIV/STD Risk Reduction (8 weeks) Flow of Participants

Number and Percentage Attending the Data Collection Sessions
Analysis of the efficacy of the intervention • Primary behavioral outcome was proportion condom-protected sex in the previous 3 months • Primary biological outcome was STD incidence • Efficacy over the 12-month follow-up period • Couple-level analysis • Generalized estimating equations (GEE) • Models control for nesting of groups within interventions and baseline measure of the criterion

Comment • First intervention showing efficacy in reducing sexual risk behavior within African American HIV serodiscordant couples • Strengths included randomized control design, high attendance, low attrition, multiple sites • Limitations included lack of random sampling and reliance on self-reports • Strong effects on measures of condom use and unprotected sexual intercourse • No effects on STD incidence
HIV serodiscordant couples have high risk of HIV transmission HIV incidence in African Americans is 83.8 per 100,000
Future Research • Additional research on couples • Other types of couples (e.g., younger) in other settings (higher prevalence) • Health promotion intervention • Chronic disease prevention in HIV positive individuals
