Evidence brief: Youth, alcohol use and HIV in Tanzania

Alcohol is an important risk factor for HIV worldwide. In 2016, 73% of new HIV infections among adolescents occurred in Africa - despite a decline in other populations - the prevalence among youth is increasing. Studies show that alcohol use influences behaviours such as multiple partnerships, unsafe sex and transactional sex that in turn increase the risk of contracting HIV. Efforts to address alcohol consumption in this region have mainly taken the form of interventions to reduce individual alcohol consumption, but these have not, in general proved effective.

In sub-Saharan Africa, young women who engage in transactional sex (the exchange of sex for money or gifts) with a male partner show an elevated risk of prevalent HIV infection. This paper analyses longitudinal data to estimate the association between transactional sex and HIV incidence. The researchers used data from a cohort of 2,362 HIV negative young women (aged 13–20) enrolled in a randomized controlled trial in rural, South Africa who were followed for up to 4 visits over 6 years.

How does partner violence affect HIV treatment during pregnancy? - Abigail Hatcher

While intimate partner violence has long been understood as a factor driving HIV risk, only recently has research and policy begun to recognise its influence in the lives of women already living with HIV. Partner violence may be particularly challenging during pregnancy, and skipping HIV medicine at this time can be especially risky for the health of the woman and her infant. This Learning Lab highlights recent work in measuring and addressing partner violence within the cascade of prevention of mother-to-child HIV transmission (PMTCT).

‘It’s because I like things… it’s a status and he buys me airtime’: exploring the role of transactional sex in young women’s consumption patterns in rural South Africa (secondary findings from HPTN 068)

‘Transactional sex’, defined as a non-marital, non-commercial sexual relationship in which money or material goods are exchanged for sex, is associated with young women’s increased vulnerability to HIV infection. Existing research illustrates that the motivations for transactional sex are complex. The fulfilment of psycho-social needs such as the need to belong to a peer group are important factors underlying young women’s desires to obtain certain consumption items and thus engage in transactional sex.

Worldwide, almost one third (30%) of women who have been in a relationship have experienced physical and/or sexual violence from an intimate partner. Given the considerable negative impacts of intimate partner violence (IPV) on women’s physical health and well-being, there is an urgent need for rigorous evidence on violence prevention interventions.

Individual and community-level risk factors for HIV stigma in 21 Zambian and South African communities: analysis of data from the HPTN071 (PopART) study

, ; Read the full paper online

HIV stigma is present whenever HIV infection is linked to negative stereotypes that mark a person living with HIV as different from the rest of the population; a separation of ‘them’ from ‘us.’ This separation then leads to status loss, which can result in negative outcomes for people living with HIV (PLHIV). Stigma experienced by PLHIV can include being gossiped about, insulted or physically assaulted in communities and healthcare settings.
