Condoms in Africa
March 22, 2009 10:25 AM Subscribe
Is this Harvard researcher citing reputable studies when he claims that: "The accepted wisdom in the scientific community is that condoms lower the HIV infection rate, but after numerous studies, researchers have found the opposite to be true. We just cannot find an association between more condom use and lower HIV reduction rates in Africa."
The only study he quotes in that particular article is his own book.
That said, he's a Harvard researcher with over 25 years of direct exposure to this particular subject (promoting condom usage in Africa, you might note), I'd venture a very solid guess that he himself has enough reputable studies under his belt to know what he's talking about, even if you don't like the sound of the conclusions he's reaching.
I'd recommend reading his book and evaluating his research process for yourself. He's written 5 other ones according to the article.
I don't have any evidence, but I do have first hand exposure to more than a dozen African cultures, some at good length, and in my personal opinion the cultural issues and the "individual" vs. "population" arguments he's making sound pretty spot on, sadly enough.

If you'd like to review some of the research yourself, go to PubMed and do this search: hiv and africa and condoms
It's important to note that the interview is being reported in the Catholic News Agency.

First, I'm always suspicious when somebody puts the word "Harvard" in front of the word "researcher."
So I went to his page. He does run Harvard's AIDS prevention project. But when I see National Review's Rod Dreher cited as approving of him on the page, I think he's likely an ideologue. I don't see other researchers touted.
Obviously there may be no population-wide measurable benefit to condom distribution. Perhaps people don't use them enough, or don't use them during their riskeist encounters. But here are the facts folks: if a person uses condoms all the time, they have a lower chance of getting AIDS. There is no denying that. So there might be a lot of reasons why it isn't working for entire populations over there that have tons to do with cultures there. But condoms themselves make it very hard for the AIDS virus to be transmitted.
So I don't see why condom distribution should stop, especially if some old German living in the Vatican thinks it ought to be so based on what he thinks Jesus said.

Response by poster: So I don't see why condom distribution should stop
I think the researcher is making the argument that condoms paradoxically increase societal infection rates, especially when compared to behavioral programs such as promoting monogamy. That's why I'm interested in the studies he's citing.

I just read the beginning of his book on Google Books and it looks more like he's arguing that in African countries, promoting condom use isn't the most effective use of resources, rather than that condoms magically stop working in Africa, or that an individual condom isn't effective against HIV transmission.

This very interesting article from the folks at Guttmacher make the excellent point - glossed over in the Catholic News Agency piece - that it's quite difficult to tease out which part of Uganda's ABC (Abstinence, Be Faithful, Condom) program was THE MOST EFFECTIVE. Which isn't surprising.
It's also not terribly surprising that after falling off, the infection rate begins to rise again. The same happens here in the U.S. in some populations. It's because people aren't very good at doing what's good for them, generally speaking, especially when it comes to something like sex.
I'll point my resident public health AIDS expert to this question when she gets home in a little bit.

Here's another view of the matter (I pasted some bits to summarize it):
Uganda’s first AIDS control programme was set up in 1987 to educate the public about how to avoid becoming infected with HIV. The programme promoted the ABC approach (abstain, be faithful, use condoms), ensured the safety of the blood supply and started HIV surveillance.
It is thought that the government’s ABC prevention campaign was partly responsible for the decline in prevalence. However, as treatment was not widely available in Uganda during this time the high numbers of AIDS-related deaths also contributed to the reduction in the number of people living with HIV.
Free antiretroviral drugs have been available in Uganda since 2004. It is thought that the availability of drugs to treat HIV may have led to complacency as AIDS is no longer an immediate death sentence; this may have contributed to the suspected rise in new HIV infections.
Many experts have also speculated that Uganda’s shift in prevention policy away from ABC towards US-backed abstinence-only programmes may also be responsible for an increase in risky behaviour, as comprehensive sex education and condom promotion are no longer mainstream.

You should note that it isn't the researcher who is claiming increased infection rates from condom promotion. "Found the opposite to be true" is not a quote in the original article, but an editorial comment.
That said, if the question is whether or not condoms lower infection rates societally, I don't know the answer. I do know, however, that every time a couple uses a condom during sex, the risk of HIV infection if the couple is serodiscordant is lowered dramatically.

Anyone who so seriously misrepresents harm reduction sets off a lot of red flags for me. I do not know him, nor am I familiar with his research, but the fact that he is mischaracterizing a very well-known intervention modality (and one strongly disliked in conservative political circles) makes me think that he has a specific political and ideological axe to grind here.

More detailed information about what has been happening in Uganda, including this excerpt:
Despite the evidence that condoms are one of the many tools necessary to combat the spread of HIV, a culture of fear and mistrust has been well cultivated in Uganda. The leadership in Uganda has taken action to impede the free access to accurate information and counseling on condom use, supported by PEPFAR-backed programs and guidelines. Since this war against condoms was initiated in 2004, HIV prevalence has increased at an alarming rate, giving valid cause for alarm. Uganda has been touted as the model of ABC success, but the ABC model is no longer promoted and implemented in the same, balanced method as before. While no single strategy offers a panacea to the HIV/AIDS epidemic, if Uganda is to once again bring the epidemic back into check, it will need to draw on all available resources, including condoms.

When I first read your question, I thought that the researcher would be some kind of nut. But, no.
To find cites without purchasing any of his books, you can look at this presentation he gave. Basically, it's a PDF of the PowerPoint slides, with speaker notes. He cites studies done, which added to his research.
This is a researcher dedicating his life to the AIDS issue. Harvard employs him (not exactly a hotbed of fundies). There's a difference between first-hand (what the researcher says) and second-hand (how the Catholic News Agency interprets and presents what the researcher says).

To see more of his publications, go to this page at the AIDS Prevention Research Project at Harvard. It has his CV and a linked list of his publications. It's a pretty impressive list, frankly. He's written over 250 peer-reviewed articles. His latest book got positive mention in Lancet.

While there are obviously many factors, Senegal has one of the lowest infection rates in Sub-Saharan Africa at under 1%, and under 20% among sex workers, and strong promotion of condom use is widely cited as part of the reason for that.

It's not an incredibly surprising finding, I don't think. Ignoring the potential controversy about condoms in particular, studies have found that safety equipment tends to encourage riskier behavior. This study, for instance. Or this salon article that describes how more traffic control signage seems to lead to increased accidents.

hal_c_on, he's been working on AIDS prevention, including extended periods in some extremely desolate areas, for the last 20+ years. You don't agree with him, fine, but your last comment is ludicrous and makes you look small.
As for the publications, check the CV. I do not read the Journal of the A.M.A., perhaps it's not up to snuff as a scientific journal?

I don't know that it's in question that he's a non-expert - he's clearly done tons of research in HIV in Africa. But a book review is not the same as a peer-reviewed study. He's published articles in peer-review publications, but the book review in the AMA journal isn't one of them.

If you're going to worship at the altar of science, then at least be pious about it. Empirical evidence is the foundation of science. He clearly has the experience and education to speak and publish about the topic. Even if you disagree with his conclusions, calling him an asshole and snarking about his qualifications isn't just small, it's anti-science.

Neither his CV nor the presentation linked to seem to indicate any expertise in epidemiology (i.e., the science of disease in human populations). His methods seem to be anthropological and his quantitative skills as indicated by his presentation are rudimentary at best. He also fails to cite the vast epidemiologic literature on AIDS in Africa, so I'm feeling little love for the guy's conclusions. YMMV.

No, he's not an epidemiologist. As bluedaisy pointed out his field is anthropology, specifically medical anthropology. Studying the effectiveness of condom use at a population level would seem to fall reasonably within that field. The presentation Houstonian linked to was a presentation to donors of the Kellogg Foundation so I assume it was written for a lay audience.
That said - I have no idea whether he is correct or not. None of the links posted in this thread are to a study which contradicts or confirms the statement, "We just cannot find an association between more condom use and lower HIV reduction rates in Africa." I just get irritated by the presumption that because someone apparently identifies with a particular religion, their views - and in this guy's case, his substantial education and experience - cannot possibly be valid.

The SEICUS one? Yeah I did. It says:
- "Since this war against condoms was initiated in 2004, HIV prevalence has increased at an alarming rate"
- "HIV prevalence rates in Uganda continue a downward trends"
And it doesn't show data to support either position. So no, I don't think that article does the trick.
- This article discusses a study which argues that the reduction in prevalence was due to the death of many of those infected. It also says:
"...while condom use has increased sharply over the last ten years, this has been counterbalanced by increases in other sexual risk behaviour and that Ugandans, at least in Rakai, appear to be less abstinent and less faithful than they were."
- This one might be more along the lines of what you're looking for: "There is no question that the condom crisis in Uganda is being driven and exacerbated by [the US President's Emergency Plan for AIDS Relief (criticized by the SEICUS article as favoring abstinence only programs)]" he said, adding that this "undoubtedly will cause significant numbers of infections which should never have occurred".
But it still doesn't offer data to support that. And also says: "[the study author] presented some behavioural data...which suggest that there has been a corresponding change in risky behaviour since 2000...'condom use doesn't appear to have changed very much'.

Please post one, then. You're not addressing the question and it doesn't seem like you've read the original article, any of the upstream links, or anything about what Green is arguing. To recap:
"We just cannot find an association between more condom use and lower HIV reduction rates in Africa," the article quotes Green as saying. Jsonic wants to know whether Green is citing reputable studies or not.
According to the presentation that Houstonian - how can Texas possibly withstand all these hits to its reputation? - linked to, Green believes that:
1. Condoms are effective in reducing risk of HIV transmission when used consistently and correctly under optimal conditions.
2. Inconsistent condom use produces little or no reduced risk
3. "inconsistency of use, disinhibiton, and non-use by married and ongoing couples lead to condoms having little/no impact at population level"
Let's look at the spaghetti on the wall, then:
UNAIDS/WHO statement on condoms, with references
The reference for the "condoms help prevent the spread of HIV in countries" statement in that link is this work, which is a discussion of the ABC approach in Uganda. Rtha already posted it upstream, and as he notes it doesn't draw any conclusions on what part of ABC worked.
Prevention of [HIV] transmission in Africa: effectiveness of condom promotion...among prostitutes.
From the original article, "Green’s research found that 'condoms have been effective' in HIV concentrated areas where high risk activities are already being conducted, such as brothels in countries like Thailand." Maybe behavioral disinhibition is not a factor for the prostitutes at this point in their lives.
HIV incidence and sexually transmitted disease prevalence associated with condom use...
Green cites this study as a reference for point #2 above. If anything, it supports his position.
And your last two links don't really touch on the question at all. If you have seen a study which supports or does not support the premise that condoms reduce HIV prevalence at the population or country level in Africa, please post it.

Here's relevant data point from UC Berkley:
"For example, condom use is widely promoted as an HIV prevention measure and is effective in countries such as Thailand, where the epidemic is spread primarily by sex workers. However, studies have found no evidence that condom use has played a primary role in HIV decline in generalized, primarily heterosexual epidemics, such as those in southern Africa, the authors note. This is mainly because most HIV transmission there occurs in more regular sexual relationships, in which achieving consistent condom use has proved extremely difficult."
