Dating for hiv positive
The circumcised men were more likely to be married and to have more than one wife, less likely to have ever been with a sex worker, or with more than three sex workers.
(Equal proportions of both groups, 10-11%, had been with one or two sex workers.) These factors could well account for the difference. The authors maintain that "because participants did not know their HIV-1 status at the time of our visit, bias from this source would seem unlikely." But many would know their HIV-1 status because of AIDS symptoms. There are thus unknown ways in which men might non-randomly "include themselves out".
It is hard to escape the conclusion that this line was written before the study began.
National Prevention Information Network September 17, 2008 Findings reported at the Australasian Sexual Health Conference 2008 shed new light on male circumcisions role in preventing HIV infection.
We may therefore be sorely tempted to misuse that power in furthering a personal prejudice or social goal -- why not provide that extra oomph by extending the umbrella of science over a personal preference in ethics or politics?
Only seven of the 53 HIV infections occurred among insertive partners; the studys model indicated that five of these infections could have been avoided if the men had been circumcised.
[No figure for how many of the seven HIV infections were among circumcised insertive men.
That one study, confined to Christians in Kenya, compared men belonging to churches that encouraged circumcision with those that discouraged it.
It used physical examination to determine circumcision status, and confined itself to churches that had similar views on polygamy and widow inheritance (of their late husbands' brothers as second husbands).As controls on "psychic" research are tightened, the effects found steadily diminish, and when control is complete, the effects vanish. These results are certainly consistent with the null hypothesis, that circumcision has no effect on HIV acquisition: the confounding factors have just not all been found yet.
