26 February 2007 - New research dramatically contradicts the popular conclusions of recently published reports, holding that male circumcision protects against contracting AIDS. Scientists looking at male circumcision and female genital mutilation (FGM) practices in Kenya, Lesotho and Tanzania found that the cut in itself was causing many new AIDS cases among adolescents.
The research, published in the March issue of the scientific
journal 'Annals of Epidemiology', was carried out by a team of researchers led
by Devon Brewer, director of the research firm Interdisciplinary Scientific
Research. "We found that circumcised virgins and adolescents in Kenya, Lesotho,
and Tanzania were consistently and substantially more likely to be infected with
HIV than their uncircumcised counterparts," Mr Brewer said.
The researchers analysed data from the 'Demographic and Health Surveys', which
are based on nationally representative samples of adolescents and adults. In the
three African countries studied, circumcision is typically performed in
adolescence or early adulthood and often in unhygienic circumstances where many
individuals are circumcised with shared, unsterilised cutting instruments.
"Sexually experienced male adolescents were no more likely to be infected than
adolescent virgins, further highlighting how HIV may be spreading by means other
than sex," the researchers concluded.
Mr Brewer said "a key problem with nearly all prior research on circumcision in
Africa is that researchers have treated circumcision only as an anatomic
characteristic, and not also as a potential exposure to others' blood during the
circumcision operation." He continued, "this is striking, because over the last
20 years, many Africans, including children, have warned that HIV can spread
through circumcision procedures."
The new results in particular raise questions about how to understand the recent
randomised trials of male circumcision in South Africa, Kenya, and Uganda. These
studies, in which some uncircumcised men were randomly assigned to be
circumcised in presumably sterile conditions and others were not circumcised,
showed that male circumcision reduced HIV acquisition.
The popular news reporting of these findings has been widespread in Africa. And
the basic message in African media has been that circumcising young boys - and
sometimes girls - will protect them from contracting HIV-AIDS. The new study
however shows that this conclusion is not only wrong, but also a dangerous
message, due to the poor hygienic standards normally applied at circumcision
ceremonies.
Mr Brewer said, "If we had known several years ago what we know now from the
national surveys, there would not have been a good empirical basis even to
conduct the trials. Therefore, it is crucial to investigate thoroughly the
possible mechanisms - which are speculative at this point - for the protective
effect observed in the trials."
The US researcher and his colleagues finally called for more intensive study of
HIV transmission in the context of both traditional and medical circumcision in
sub-Saharan Africa.
