"These findings suggest that reduction in sexual partners and abstinence among unmarried sexually inexperienced youth (particularly in urban areas and in mails), rather than condom use, are the relevant factors in reducing HIV incidence." (page 2)
Here's the article.
On a side note...
When reading a scientific article it is important to have a clear understanding of how science actually works. Presenting a single article and saying "There, that proves it!" does not work. The scientific method requires that results be repeatable. So, more literature should back up a claim. But even that can fail, because science is fueled by research, and research by grants, and grants are money. That may be a run-on sentence, but the point is: scientists have a bottom line, too.
So, when you read a science article think of science as trying to be less wrong than the other guy. And think of it in the greater picture. A single article must be in context, and unless the date is within the last few years, you should look at the entirety. That's why research takes so long.
