What Is the Evidence Base?
Contains: Approximately 4,000 citations 641 interventions with outcomes summarized –

Rating the Evidence
14
Type Strength of evidence (modified from Gray, 1997)
I Strong evidence from at least one systematic review of multiple well designed, randomized controlled trials.
II Strong evidence from at least one properly designed, randomized controlled trial of appropriate size.
IIIa Evidence from well-designed trials/studies without randomization that include a control group (e.g. quasi-experimental, matched case-control studies, pre-post with control group)
IIIb Evidence from well-designed trials/studies without randomization that do not include a control group (e.g. single group pre-post without, cohort, time series/interrupted time series)
IV Evidence from well-designed, non-experimental studies from more than one center or research group.
V Opinions of respected authorities, based on clinical evidence, descriptive studies or reports of expert committees.
15
What Works vs. Promising
What Works
Strongly rated studies (Gray I, II, or IIIa) for at least two countries and/or five weaker studies across multiple settings
Promising Studies that were strongly rated but in only one setting or a number of weaker studies (IIIb, IV and V) in only one country or region.

WHAT IS NEW IN 2012
18
• Main themes• Prevention• Treatment• Strengthening the
enabling environment
Covering

Women’s solidarity pin. www.lovingafrica.com
• Exciting time with new prevention and treatment modalities
• Gender equitable interventions still need to be devised and scaled up
• Critical Prevention Approaches Still Under Development – Vaccines, Pre-exposure Prophylaxis, Microbicides
Main Themes
20
PREVENTION
In2eastafrica.net
• Wide agreement that prevention is still critical and needs to be scaled up
– WHO et al., 2011b; Zachariah et al., 2011; Over, 2011; Padian et al., 2011; Kurth et al., 2011; Katsidzira and Hakim, 2011; Dieffenbachbach and Fauci, 2011.
• Prevention challenges for women remain – Key affected populations, are underserved – Focusing on key affected groups can leave out other
women also at risk of HIV– Meeting the prevention needs of young women is
particularly critical – Addressing the enabling environment is key
Prevention
22
Treatment as prevention: ARV therapy reduces (but does not eliminate) the risk of HIV transmission is an additional
prevention strategy (Works)

Study Countries Findings
Atti a et al., 2009
I Systemati c review of 11 cohorts reporti ng on 5,021 heterosexual couples and 461 HIV transmission events
Sub-Saharan Africa
heterosexual transmission was reduced by 92%
Cohen et al., 2011
II RCT of 1,763 serodiscordant couples in nine countries
9 countries: 5 Africa; 2 Asia, 1 LAC, US
Transmission rate:• Early initiation of ART: .1
per 100 person years • Later initiation: .9 per 100
person years 96% relative risk reduction
Donnell et al., 2010
IIIa Prospecti ve cohort analysis of 3,408 heterosexual HIV serodiscordant couples
7 countries in Africa
Transmission rate• On ART: .37 per 100 person
years • Not yet on ART: 2.24 per
100 person years 92% relative risk reduction
• Monogamy cannot be assumed in serodiscordant couples– In one study, 28% of the cases HIV transmission occurred from
another partner rather than from the HIV-positive partner on treatment (Cohen et al. (2011)
• Early treatment will not stop transmission from those who are acutely infected but cannot know their serostatus with rapid HIV tests (Cohen, 2011b)
• Other challenges include:– long-term adherence, the possibilities of drug resistance, and
the concerns that condom use and other preventive measures would decrease (Shelton, 2011)
• A continued focus on all prevention modalities is warranted (Nguyen et al., 2011)
Treatment as prevention (challenges)
24
• VMMC averts HIV infection among women, because as more men are circumcised, women are less likely to encounter sexual partners who are living with HIV (Njeuhmeli, 2011; Hankins et al., 2011; Ally et al., 2012; Hallett et al. 2011)
Voluntary Medical Male Circumcision Can Help Women
25
• MC programs could be a platform to promote gender equity and all HIV risk reduction strategies as well as men and women’s sexual and reproductive health with increased couple communication (Wamai et al., 2011; Doyle et al., 2010b).
• There is still a need to scale up female condoms and continue a focus on condom promotion (Abdool Karim et al., 2010; Hughes et al., 2012)
• Condom negotiation skills and peer education for women works (Weschberg et al., 2010; Kaponda et al., 2011).
Condoms Are Still Critical
26
“Condom issues are difficult. We know we can prolong our lives if we do not infect each other. On the other hand, marriage is also important… We cannot survive without men. Who will help us meet our needs?” —Woman who dropped out of a PMTCT program, Malawi (Chinkonde et al., 2009: 14).
• HIV prevention is not being scaled up sufficiently among vulnerable groups – Fewer than half of all sex workers are reached in Asia (Baral et
al. 2012)
– Only 1 in 5 IDU reached in Asia (Low-Beer and Sarkar, 2010)
– Modeling suggests 60-80% coverage needed to reduce HIV• Key affected groups need prevention, care, and
treatment– Often not reached with testing and counseling (WHO et al., 2011)
– Issues around treatment access (e.g., prosecution of health workers) (Schwartlander et al. 2011)
Sex Workers and Females Who Inject Drugs/Partners of Males Who Inject
Drugs are Underserved
27
What works • Comprehensive prevention programs • Clinic-based interventions with outreach workers • Policies that involve sex workers, brothel owners and clients • Providing STI clinical services • Peer education • Creating a sense of community and empowerment among sex workers. • Sex workers can be as adherent to antiretroviral therapy as other
populationsPromising strategies
• Interventions targeting male clients can increase condom use and thus reduce HIV risk for sex workers
Still needed• Access to information and services for contraception and dual method
use
Sex Workers – We Know What Works; We Need to Do It
28
What Works:• Comprehensive harm reduction programs, including needle
exchange programs, condom distribution, opioid agonist therapy and outreach, and nonjudgmental risk reduction counseling.
• Peer education • Sex-segregated group sessions • Instituting harm reduction programs in prisons• Drug users benefit from and can be adherent to antiretroviral
therapy.
• Promising Strategies:• Offering no-cost HIV testing and counseling to people who use
drugs

TREATMENT
blog.lass.uk.org.uk
• Treatment is a huge success story for both women and men.– Between 1995 and 2009, an estimated 14.4
million life-years have been gained among adults as a result of ART (Mahy et al., 2010b)
• Universal access and loss to retention and follow-up remain concerns.
• Gender roles and norms affect treatment access for women and men (e.g., Skovdal et al., 2011b; Foster et al., 2010b; Fox et al., 2010a; Thomas et al., 2009; Arrivillaga et al., 2009)

STRENGTHENING THE ENABLING ENVIRONMENT
“Almost uniformly across the world, women have less access to and control of productive resources outside the home. Evidence for this imbalance in power includes the gender gaps in literacy levels, employment patterns, access to credit, land ownership and school enrollment fees. This imbalance in access to, and control of, productive forces and resources translates into an unequal balance in sexual relations in favor of men” (Abdool Karim et al., 2010: S126).
Strengthening the Enabling Environment
33
• Transforming gender norms • Addressing violence against women• Transforming legal norms to empower women,
including marriage, inheritance and property rights
• Promoting women’s employment, income and livelihood opportunities
• Advancing education• Reducing stigma and discrimination• Promoting women’s leadership, starting with girls
Aspects of the Enabling Environment
34
• Traditional gender norms lead to behaviors that put women – and men – at risk for HIV (Stephenson, 2010; Pulerwitz et al. 2010).
Transforming Gender Norms
35
Interventions to address gender norms and reduce HIV need to work with “men and women, boys and girls, in an intentionally and mutually reinforcing way that challenges gender norms, catalyzes the achievement of gender equality and improves health” (Greene and Levack, 2010: vi).
Transforming Gender Norms
What Works• Training, peer and partner discussions, and community-based
education that questions harmful gender norms• Mass media campaigns that take up gender equality as part of
comprehensive and integrated services Promising Strategies:• Changing norms regarding the acceptability of multiple and
concurrent partnerships Still needed• Interventions to change gender norms need to be scaled up
