HIV and Key Populations

Groups that are disproportionately affected by HIV are known as Key Populations, or Inadequately Served Populations. While those identified as Key Populations will vary by local context, the UNAIDS definition includes men who have sex with men, sex workers, people who use drugs and transgender people. UNAIDS data suggests that more than 90% of new HIV infections in central Asia, Europe, North America, the Middle East and North Africa in 2014 were among people from key populations and their sexual partners, equivalent to 45% of new infections worldwide.

Key population groups face high levels of stigma, discrimination and violence and in many countries they are criminalised. In this context, key populations will face high barriers to accessing HIV and health services.  An effective HIV response will protect and promote the human rights of key populations and prioritise evidence based interventions, led by the communities most affected by HIV.

STOPAIDS recently developed a factsheet on Sex Work, HIV and Human Rights. We will be starting work on a factsheet on HIV and LGBT issues (exact scope TBC) in September. Contact Alysa for more information.

While not key populations, HIV also disproportionately affects women & girls and young people.


HIV and Women and Girls

AIDS is the leading cause of death among women of reproductive age. In 2015, an estimated 17.8 million women (15 and older) were living with HIV globally, representing 51% of all adults living with HIV. Adolescent girls and young women are particularly affected by HIV. In 2015, adolescent girls and young women (15-24) accounted for 20% of all people acquiring HIV, despite representing just 11% of the population. 60% of young people (15-24) living with HIV are women and girls.

Gender inequality fuels the HIV epidemic. Women’s unequal status in society affects their right to make choices about their own health and restrictive laws and norms affect access to comprehensive sexuality education and to sexual and reproductive health and rights (SRHR). Globally, 225 million women still have an unmet need for family planning commodities.

Gender based violence (GBV) leads to a higher incidence of unsafe sex and a lower ability to negotiate condom use. Emerging evidence suggests that GBV can also have a biological effect on immune and hormonal functions believed to affect HIV acquisition and disease progression.4 Around a third of women experience intimate partner violence (IPV) in their lifetime, increasing the risk of acquiring HIV by 50% in high prevalence settings. Once diagnosed, women living with HIV experience increased levels of GBV, especially in healthcare settings. GBV can then act as a barrier to accessing antiretroviral therapy (ART) and other treatment. Evidence has shown that the impact of IPV on treatment adherence for women is the same or greater than the impact of HIV-related stigma and discrimination.

Social norms around child marriage, age discordant relationships and early sexual debut can also affect HIV acquisition. For example, a recent CAPRISA study revealed a cycle of HIV transmission where girls and young women acquire HIV from men who are on average eight years older then them. Many of the men in the study also had partners of a similar age, among which HIV prevalence rates exceeded 60%. Age related and gender related power dynamics make it extremely challenging for girls and young women to negotiate condom use with older male partners.

Given the disproportionate impact of HIV on women and girls – all actors focusing on programming for women and girls should consider how to include within their work. The Department for International Development (DFID) has been a global leader on development programming for women and girls, putting into legislation that the UK must consider how international development spending affects gender. DFID also pushed the Global Fund to fight AIDS, TB and Malaria to include gender as a priority within its strategy. Yet DFID can still go further to include HIV within its work on women and girls.  STOPAIDS is calling on DFID to explicitly include HIV within its Strategic Vision on Women and Girls.


HIV and Young People

Adolescents and young people continue to be disproportionately affected by HIV. In 2014, 3.9 million young people (15-24) were living with HIV and 62,000 young people (15-24) newly acquired HIV. AIDS is the leading cause of death amongst adolescents in sub-Saharan Africa, and the second leading cause globally. Adolescents are the only age group amongst which AIDS-related deaths are increasing.

The HIV epidemic is underpinned by gender inequality, which exposes girls and women to gender-based violence and restricts access to sexual and reproductive health and rights (SRHR), increasing their vulnerability to HIV. In 2015, 20% of people who had newly acquired HIV globally were young women aged 15-24 (despite representing just 11% of the population). In areas of sub-Saharan Africa young women are up to eight times more vulnerable to HIV acquisition than young men in the same age group.

Multiple and intersecting forms of discrimination and structural  inequality can impact the lives of young people as they experiment with identity. Young people belonging to a key population group (men who have sex with men, transgender people, people who use drugs, and sex workers) are disproportionately affected by HIV. For example, in Asia, 95% of young people diagnosed with HIV fall into at least one of the above groups.

There are considerable data gaps around adolescents and young people and HIV, particularly for younger adolescents because of the challenges in getting parental approval for their involvement in surveys and a lack of age-appropriate questions. Where data exist, limited sample sizes and lack of disaggregation limits the available evidence to inform programming. In part because of these gaps, adolescents and young people are often missing from national HIV strategic plans, particularly in a way that goes beyond preventing vertical transmission

The disproportionate impact of HIV on young people, indicates that any actor focusing on young people should consider how HIV fits into programming. DFID has been a champion for young people in international development, but could go further to integrate HIV into its work. For example, DFID’s Youth Agenda does not mention HIV. Although the Agenda is unlikely to be immediately renewed, STOPAIDS recommends that DFID consider how HIV can be included as the Youth Agenda is operationalised.
