The research shows that depression is common among young South Africans, and could be making a significant contribution towards the HIV epidemic.
As well, the researchers believe that depression could be contributing to risky sexual behaviours around the world, and that preventing or treating it may reduce the global burden of sexually transmitted diseases, including HIV and AIDS.
Ian Colman and Mzikazi Nduna, researchers from the U of A's School of Public Health, studied 1,002 females and 976 males between the ages of 15 and 26 living in Eastern Cape Province, South Africa. Study participants were surveyed twice, once in 2002, and again 12 months later.
The research found that 21.1 per cent of women and 13.6 per cent of men reported symptoms of depression. Depressed women were more likely to be in controlling relationships, to have a partner who was several years older, and to have experienced sexual violence. Men with depressed symptoms were more likely to have had three or more lifetime partners, experienced transactional sex and committed rape.
All of these behaviours are considered to put young women and men at risk for sexually transmitted HIV.
The research appears in the newest issue of the Journal of the International Aids Society.
Based on their findings, Colman and Nduna recommend routine screening for prevention, diagnosis and management of depression among youth as a means to reducing risky sexual behaviours and, in turn, HIV risk in South Africa.
"Access to mental-health services for young people remains elusive as resources and are directed to more pressing conditions such as teenage pregnancy and HIV prevention," Nduna said. The researchers see potential for blending depression prevention into current sexual and reproductive health clinic services. "Clearly we could achieve better success in our prevention efforts if they are delivered to clients who are in a healthy state of psychological well-being," added Colman, an assistant professor of epidemiology.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
