What is it?
Work with/for people living with HIV and AIDS (PLHAs) to prevent the onward transmission of HIV
Gets called both ‘primary’ and ‘secondary’ prevention according to tradition

Positive prevention makes sense
“Preventive interventions with positive individuals are likely to have a greater impact on the epidemic, for an equivalent input of cost, time, resources, than preventative interventions focused on negative individuals. “A change in the risky behaviour of an HIV positive person will, on average, and in almost all affected populations, have a much bigger impact on the spread of the virus than an equivalent change in the behaviour of an HIV negative person.” King-Spooner S. HIV prevention and the positive population. Int J STD AIDS 10(3):141-50. 1999. www.guscairns.com

Why not part of prevention from the start?
“Historically, there has been a reluctance to work on HIV/STI prevention with people with HIV because of perceptions that the concept of prevention for people already infected is inherently victimising an already stigmatised surrounding people with HIV’s contradictory.
“There have also been justifiable concerns about group. In addition, there has been a reluctance to acknowledge that people with HIV have sex, and also to get to grips with the complex ethical issues responsibilities towards others.” International HIV/AIDS Alliance.

CDC in USA calculates that when diagnosed, PLHAs cut risk behaviour by 2/3 Universal testing drive: recommended testing all 13-65 year olds: Washington DC recently extended this to 85 Then what? CDC prevention interventions mention: ongoing case management focused risk-reduction counselling medical interventions (leaving these undefined) support for other psychosocial stressors (leaving these also undefined) www.guscairns.com
IAPAC Session on Positive Prevention, 13.10.06
Are CDC’s assumptions justified?
Meta-analysis of 11 US studies
53% reduction in unprotected sex post-diagnosis
78% reduction in unsafe (i.e. unprotected and serodiscordant) sex after diagnosis
www.guscairns.com
IAPAC Session on Positive Prevention, 13.10.06
Are CDC’s assumptions justified?
Typical study: 113 recently HIV-infected gay men. Interviewed 3 months and six weeks after diagnosis.
47% reported decline in sexual partners at second interview, 34% the same, 19.5% an increase. Overall decline; 34% Unprotected sex did not decline but unprotected sex with negative partners declined 37.5% and with partners of unknown status 47%.

Are CDC’s assumptions justified?
Longitudinal study in HIV- negative female ‘sex workers’, Mombasa, 1993-2000 Ave follow-up > five years, 3.8 post-diagnosis N= 1600: 265 seroconversions = 7.7% p.a.
44% maintained through time – but after adjusting for age OR= 0.69
reduction in unsafe sex incidents after seroconversion – 100% condom use up from 59% to 67% More than one sexual partner in previous week declined from 20% to 9% More than two sexual encounters in previous week declined from 27% to 16% McClelland RS et al.

How much behaviour change do you need to reduce prevalence?* When R(t) >1, epidemics will increase. R(t) = c. annual incidence/prevalence ratio (IPR(t)) IPR must be < 1/ survival time for prevalence to decline. If mean survival with HIV is 20 years, IRP has to be <0.05.
Denmark study†: Survival time with HIV if diagnosed at 25 = 18 years men, 24 years women IPR in gay men in UK is c. 0.11 and slowly increasing. ∴ May need 50-66% to contain epidemic.

Positive prevention and positive-
led
prevention
Easier to reinforce a positive behaviour than change a negative one Information alone is not enough. People need information, motivation and behavioural skills Programmes should be tailored to help people sustain behaviour that supports good sexual health and relationships, and to address barriers to adopting them.

Should we promote serosorting?
‘Knowledge’ of another person’s HIV status may in fact be guesswork* *Hickson F et al. London Counts: HIV prevention needs and interventions among gay and bisexual men in the sixteen London Health Authorities. Sigma Research, 2001. ISBN 0 872956 51 3 www.guscairns.com

Should we promote serosorting?
Serosorting does not prevent other Sexually Transmitted Infections† Herida M et al. Rectal lymphogranuloma venereum surveillance in France 2004-2005. Eurosurveillance Monthly, vol 11 Issue 9, September 2006.

Should we promote serosorting?
Serosorting is elective unprotected sex. Ethical problem about promotion.
But serosorting requires two conditions to work….
Knowledge of status Disclosure of status
…and we should promote those!

HIV+ people do use condoms…

Toronto disclosure posters
Uganda (King): 1,092 HIV-positive. 69% had disclosed HIV status to partner. Higher rates of disclosure ⇔ higher rates of condom use. South Africa (Simbayi): > 1,000 HIV+ people: 58% disclosed HIV status to partner: disclosure ⇔ less unprotected sex. France (Spire): 1,187 HIV+ people: 95% had disclosed to partner: of men and 91% of women non -disclosure ⇔ unprotected sex in gay men but in heterosexuals with poverty Botswana (Percy-de Korte) 90% of 275 ARV recipients disclosed HIV status to family, 71% to partner. 48% had reduced number of sexual partners since diagnosis. But 39% said that receiving ARVs had resulted in either reduced condom use or more partners. www.guscairns.com

So what works in behavioural interventions?
(Two meta-analyses, 2006) Nicole Crepaz, AIDS 20 : 143–157. 2006.
Measured ‘sexual risk incidents’ after 12 RCT interventions Significant reduction (43%) What worked: Interventions specifically focused on safer sex… Which also included help with disclosure, self-esteem etc Were intensive Were delivered in a clinical setting or at a voluntary organisation providing services At least partly delivered by professional counsellors At least partly delivered on a one-to-one basis www.guscairns.com

What works II
Blair Johnson, JAIDS 19 RCT interventions 41(5): 642-650. 2006.
Ave 16% increase in condom use Worked better for: Younger ‘Motivational*’ or taught behavioural skills (12% condom use increase) or both (33%) Non-gay; but no programme directed at gay men provided both ingredients proven to be necessary Information alone made no difference but helped other components * Motivational = providing things that improved participants’ overall quality of life such as increased social support or self-confidence.

Quote from Johnson
“Perhaps the most surprising finding of this work is that more than two decades into the epidemic, there have been so few randomly-controlled trials of interventions that focus in people living with HIV, though there have been literally hundreds of studies conducted with uninfected populations. There is an urgent need for research in this area.” www.guscairns.com
IAPAC Session on Positive Prevention, 13.10.06
Compare prevention for HIV-
Largest meta-analysis is Albarracin (2005). Covered 345 intervention groups and 99 control groups. Only outcome measure = condom use What worked best: ‘Active’ interventions increased condom use by 30%, ‘passive’ ones by 5% Taught behavioural skills Used cognitive work to improve attitudes towards condom use At least partly delivered in clinical settings Arguments that used threat or fear [‘loss framed’] consistently failed to work www.guscairns.com
IAPAC Session on Positive Prevention, 13.10.06
Loss-framed and gain framed messages
From Richardson, 2004 Gain-framed: “We encourage you to make choices that do not put yourself or others at risk. Safer sex strains of HIV” protects you from other STDs and other Loss-framed: “We encourage you to make choices that do not put yourself or others at risk. Unsafe sex of HIV” exposes you to other STDs and strains Loss-framed messages do not work with HIV negative people. Gain framed messages do not work with HIV positive people.
Why? Control. People respond to messages implying that they are capable of making a change that will have a directly protective effect on their health.

BEWARE: what seems to work may not!
SUMIT study, SF and NY, USA*
811 HIV+ gay men randomised to one discussion session or six 3-hour workshops. Videos, discussion groups, roleplay, freebies They loved it! Very high scores for enjoyment, learning, life changes, new friends Made no difference to behaviour at all. Unprotected sex marginally but non-significantly improved; disclosure got marginally worse *Wolitski RJ et al. Effects of a peer-led behavioral intervention to reduce HIV transmission and promote serostatus disclosure among HIV-seropositive gay and bisexual men.
AIDS
19(Suppl 1): S99-109. 2005.
www.guscairns.com
IAPAC Session on Positive Prevention, 13.10.06
What seems to work may not. Why?
Used community rather than clinical setting: health not emphasised Emphasis on protecting partners rather than own health. Self interest works better than guilt.
Gain-framed messages (‘you’ll protect others’) rather than loss framed ones (‘you’ll mess up if you don’t’). Evidence* that loss framed messages work better with HIV+ people.
Peer group structure can be counterproductive. The cautious end up modelling the risk-takers! Improved confidence can mean improved ability to find sex!
Too many choices? Maybe one method (condom use, disclosure, serosorting) should be taught at a time.
Worked better in SF than NY. Pre-existing community structure and norms matter.

What works? Conclusion
Based on behavioural theory At least partly conducted by skilled professionals Clinical or service-providing setting One-to-one or group, but not ‘peer group’ ‘Loss framed’, emphasising adverse consequences of unsafe sex to health and relationships Specifically addresses safer-sex skills but also… …Addresses what Johnson calls ‘myriad of other issues relating to HIV’ eg mental health, disclosure, stigma, employability, poverty, isolation etc.

Criminalisation of HIV transmission
10 convictions now in UK, all custodial, two women, one gay man, one IDU, six African heterosexual men Issues: Poor quality of defence and judicial knowledge of HIV (acquittal in one case with really good scientific evidence) Considerable controversy within and outside affected communities Stigmatisation and demonising of ‘AIDS assassins’ Legal moves in some European countries (Netherlands, Germany, Sweden) have either succeeded in or aim to restrict HIV prosecutions 200+ convictions in USA, 30 in Austria Public consultations ongoing www.guscairns.com
IAPAC Session on Positive Prevention, 13.10.06
Criminalisation has changed the game
If PLHAs are going to continue to get jailed for transmitting HIV then: We have a legal, social and moral responsibility to help PLHAs not transmit HIV Notions of ‘joint responsibility’ are less relevant: we are not jointly responsible for preventing HIV if the law says it’s the HIV+ partner who is And since prevention work directed at PLHAs is more efficient anyway, prevention funding must either increase or be redirected to work with PLHAs www.guscairns.com

Questions
Should we concentrate HIV prevention resources on PLHAs? What methods would work to increase the uptake of HIV testing?
What kind of intervention do you think would work best to help PLHAs reduce risk of onward transmission?
Given the limited reach and labour intensive nature of counselling and support-group work, what ‘broadcast’ methods might work?
