HIV This Week

Hunter M. The changing political economy of sex in South Africa: the significance of unemployment and inequalities to the scale of the AIDS pandemic. Soc Sci Med. 2007;64(3):689-700.

Between 1990 and 2005, HIV prevalence rates in South Africa jumped from less than 1% to around 29%. Important scholarship has demonstrated how racialized structures entrenched by colonialism and apartheid set the scene for the rapid unfolding of the AIDS pandemic, like other causes of ill-health before it. Of particular relevance is the legacy of circular male-migration, an institution that for much of the 20th century helped to propel the transmission of sexually transmitted infections among black South Africans denied permanent urban residence. But while the deep-rooted antecedents of AIDS have been noted, less attention has been given to more recent changes in the political economy of sex, including those resulting from the post-apartheid government's adoption of broadly neo-liberal policies. As an unintentional consequence, male migration and apartheid can be seen as almost inevitably resulting in AIDS, a view that can disconnect the pandemic from contemporary social and economic debates. Combining ethnographic, historical, and demographic approaches, and focusing on sexuality in the late apartheid and early post-apartheid periods, this article outlines three interlinked dynamics critical to understanding the scale of the AIDS pandemic: (1) rising unemployment and social inequalities that leave some groups, especially poor women, extremely vulnerable; (2) greatly reduced marital rates and the subsequent increase of one person households; and (3) rising levels of women's migration, especially through circular movements between rural areas and informal settlements/urban areas. As a window into these changes, the article gives primary attention to the country's burgeoning informal settlements--spaces in which HIV rates are reported to be twice the national average--and to connections between poverty and money/sex exchanges.

Editors´note: Political economy analyses help conceptualise HIV as a symptom of ‘structural violence’ with sex as a mode of transmission. Housing, employment, and social equality are clearly linked to HIV, both historically and contemporarily, and help explain the striking scale of the South African epidemic. This article, which suggests ways to reconfigure the response to AIDS around a more politically enabling agenda, makes for thought-provoking reading.

Kang M, Dunbar M, Laver S, Padian N. University of California Programme in Women's Health, University of California-San Francisco, 50 Beale Street, San Francisco, CA 94105, USA. Maternal versus paternal orphans and HIV/STI risk among adolescent girls in Zimbabwe. AIDS Care. 2008;20(2):214-7.

The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Orphans (whether orphaned by AIDS or other causes) have been shown to have economic and educational disadvantages as well as poor reproductive health outcomes. Kang and colleagues recruited a convenience sample of 200 girls in a peri-urban area of Zimbabwe to examine the impact of orphan status (compared to non-orphans) on household composition, education, risk behaviour, pregnancy and prevalent HIV and HSV-2 infection. In the study population, maternal orphans were more likely to be in households headed by themselves or a sibling, to be sexually active, to have had a sexually transmitted infection, to have been pregnant and to be infected with HIV. Paternal orphans were more likely to have ever been homeless and to be out of school. The findings suggest that maternal care and support is important for HIV prevention. This finding corroborates previous research in Zimbabwe and has implications for intervention strategies among orphan girls.

Editors´note: Because of recruitment methodology, these results are not generalizable, however they do provide food for thought. Although paternal orphanhood had more of an impact on household financial stability and orphaned girls’ educational attainment, the loss of a mother affected behavioural risk and biological outcomes (HIV, HSV-2). Keeping mothers alive helps reduce sexual risk in adolescent girls. How would orphaned adolescent girls in Zimbabwe benefit from support and mentoring by women in their communities?
