Keeping young South Africans in school: A “social vaccine” against AIDS

17.01.2008
A study published today in the Journal of Epidemiology and Community Health suggests that secondary school attendance is linked to lower risk of HIV infection among young people in rural South Africa.

The study, a collaboration between the School of Public Health, University of the Witwatersrand and the London School of Hygiene and Tropical Medicine (LSHTM), examined sexual behaviour and HIV prevalence among 916 young men and 1003 young women aged 14 to 25 in rural South Africa. The researchers wanted to know whether youth who remain in school are at higher or lower risk of HIV infection, compared to similar, out-of-school peers.

The team, led by Dr. James Hargreaves of the LSHTM’s Infectious Disease Epidemiology Unit, found that among both sexes, those in school reported fewer sexual partners, compared to their out-of-school peers. For female students, this partner reduction was accompanied by other protective behaviours such as greater condom use, less frequent sex, and partners who were closer to their own age. Strikingly, male students were much less likely to be HIV positive than their out-of-school peers.

In light of recent setbacks, such as the disappointing closure of the Merck HIV vaccine trial, such findings suggest that we should not overlook potential “social vaccines” which, in addition to biomedical interventions, can play a critical role in HIV prevention. Dr James Hargreaves comments: “Our study suggests that, in South Africa, being in school can shape young people’s social networks, leading to less high-risk sexual behaviour and, therefore, lower rates of HIV infection. We also recently conducted a review of 36 studies across sub-Saharan Africa which came to the same conclusions – that across a number of countries, those with higher education may now be at lower risk of HIV infection, reversing previous trends. We need to accelerate efforts to increase access to education, including secondary education, if we are going to make an impact on this epidemic. It’s encouraging that African governments, the G8, the World Bank, and others have committed to these goals – now there is even more evidence why we should do it.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
