Alcohol consumption is associated with risks for sexually transmitted infections (STI), including HIV/AIDS. In this paper, we systematically review the literature on alcohol use and sexual risk behavior in southern Africa, the region of the world with the greatest HIV/AIDS burden. Studies show a consistent association between alcohol use and sexual risks for HIV infection. Among people who drink, greater quantities of alcohol consumption predict greater sexual risks than does frequency of drinking. In addition, there are clear gender differences in alcohol use and sexual risks; men are more likely to drink and engage in higher risk behavior whereas women's risks are often associated with their male sex partners' drinking. Factors that are most closely related to alcohol and sexual risks include drinking venues and alcohol serving establishments, sexual coercion, and poverty. Research conducted in southern Africa therefore confirms an association between alcohol use and sexual risks for HIV. Sexual risk reduction interventions are needed for men and women who drink and interventions should be targeted to alcohol serving establishments.

Although there has been progress in AIDS stigma research, there are no multi-item AIDS stigma scales that have been shown reliable and valid in Africa. The current research reports the development of the nine-item AIDS-Related Stigma Scale. Research conducted in five South African communities (N = 2306) found the scale internally consistent, alpha = 0.75 and time stable over 3 months, r = 0.67. The scale was also reliable in three different languages (English, Xhosa, and Afrikaans). Correlations showed that the AIDS-Related Stigma Scale was moderately inversely correlated with years of education and AIDS knowledge. In addition, individuals who stated that HIV positive persons should conceal their HIV status had higher AIDS-Related Stigma Scale scores. Also supporting the scale's construct validity, individuals who refused to report whether they had been tested for HIV scored higher on the AIDS-Related Stigma Scale.

BackgroundThree national HIV household surveys were conducted in South Africa, in 2002, 2005 and 2008. A novelty of the 2008 survey was the addition of serological testing to ascertain antiretroviral treatment (ART) use.Methods and Principal FindingsWe used a validated mathematical method to estimate the rate of new HIV infections (HIV incidence) in South Africa using nationally representative HIV prevalence data collected in 2002, 2005 and 2008. The observed HIV prevalence levels in 2008 were adjusted for the effect of antiretroviral treatment on survival. The estimated “excess” HIV prevalence due to ART in 2008 was highest among women 25 years and older and among men 30 years and older. In the period 2002–2005, the HIV incidence rate among men and women aged 15–49 years was estimated to be 2.0 new infections each year per 100 susceptible individuals (/100pyar) (uncertainty range: 1.2–3.0/100pyar). The highest incidence rate was among 15–24 year-old women, at 5.5/100pyar (4.5–6.5). In the period 2005–2008, incidence among men and women aged 15–49 was estimated to be 1.3/100 (0.6–2.5/100pyar), although the change from 2002–2005 was not statistically significant. However, the incidence rate among young women aged 15–24 declined by 60% in the same period, to 2.2/100pyar, and this change was statistically significant. There is evidence from the surveys of significant increases in condom use and awareness of HIV status, especially among youth.ConclusionsOur analysis demonstrates how serial measures of HIV prevalence obtained in population-based surveys can be used to estimate national HIV incidence rates. We also show the need to determine the impact of ART on observed HIV prevalence levels. The estimation of HIV incidence and ART exposure is crucial to disentangle the concurrent impact of prevention and treatment programs on HIV prevalence.

Background-Anal intercourse is an efficient mode of HIV transmission and may play a role in heterosexual HIV epidemics of southern Africa. However, little information is available on the anal sex practices of heterosexuals in South Africa.
