Introduction
‘Key populations’ describe individuals who are disproportionately affected by some serious illnesses (such as HIV), but have significantly lower uptake of essential health services due to social marginalisation, legal and social conditions, stigma and human rights violations.1 The term is especially relevant in determining an appropriate response to the HIV epidemic where inequities in vulnerability are experienced by different subgroups within the population. Key affected populations include lesbian, gay, bisexual, trans and intersex (LGBTI) people, including men who have sex with men (MSM) and women who have sex with women (WSW), sex workers (people who exchange sexual services or favours for money or gifts) and injecting drug users (IDU). MSM and WSW have been consistently used as terminology to include people globally, and within Africa (including Zimbabwe), who may not identify with ‘gay’ or ‘lesbian’.2–4
Key populations may experience health vulnerability beyond the risk of HIV infection. There is increasing recognition that LGBTI people represent minority communities with unique healthcare needs.5 ,6 Access to health and psychosocial care for marginalised populations in general, and in Africa in particular, is poorer than for the general population. LGBTI people have a relatively higher prevalence of life-limiting illnesses, particularly cancer,7 ,8 and greater all-cause mortality than heterosexual people.9 Discrimination against any minority or socially disadvantaged group is a significant risk factor for stroke, heart disease, poor mental health, psychological distress and depression.10 ,11 There is global variance in acceptance of homosexuality with secular and more affluent countries demonstrating greater acceptance, and widespread rejection in Africa and in poor, highly religious countries.12
Estrangement from family and stigmatisation from healthcare staff reinforce widespread discrimination against key populations.13 Globally, MSM are disproportionately affected by HIV. In sub-Saharan Africa, MSM have an HIV prevalence four times that of heterosexual men.14 Stigma and discrimination against LGBTI individuals are common in Southern Africa,15 and same-sex practicing Africans living with HIV are known to be marginalised by HIV programmes, increasing the probability of premature death.16 Research in Central and Southern Africa has found that WSW have poorer sexual and reproductive health17 and higher prevalence of forced sex,18 while MSM have experience of human rights abuse.19 Perceptions of stigma are known to discourage people from testing and seeking treatment worldwide,20 and discriminatory practices often result in exclusion and inadequate care provision.13
Despite historical acceptance of same-sex relationships in Africa,21 the current Zimbabwe Criminal Law (Codification and Reform) Act makes specific sexual acts illegal, but falls short of criminalising LGBTI status.22 The popular belief, however, driven by political attitude and an uninformed media is that it is a crime to identify as LGBTI. Homophobic statements by government leaders in public fora and reported in the national press contribute to a misinformed, highly discriminatory sociopolitical environment. While recent moves towards upholding rights of sexual minorities in Malawi have been greeted with cautious optimism,23 in several African states, most notably in Nigeria and Burundi, attempts have been made to extend criminalisation of same-sex practice with harsh and sometimes lethal punitive measures. The unintended health-related consequence of such highly stigmatised environments is reluctance by sexual minorities to access early diagnostic and treatment services and care programmes.14
Sex workers also routinely experience discrimination, hostility, denial of, or precarious access to, health services across Kenya, Zimbabwe, Uganda and South Africa.24 In Zimbabwe, the Criminal Law Act makes soliciting, procuring and living off the earnings of sex work a crime. Research with sex workers in Africa has generally focused on risk behaviours and disease transmission, rather than illness experiences and access to care although health worker stigma has been identified as one of several challenges facing sex workers accessing hospital HIV treatment in Zimbabwe.13
There has been limited research of the specific health outcomes and experiences of trans people, outside of the context of HIV and studies of MSM or WSW. However, one study of trans people in South Africa reported unacceptable care, with frequent experiences of hostility and discrimination.25 To date, no study has aimed to understand the experiences of access to healthcare (beyond HIV) across key populations in Africa. The aim of this study was to explore the healthcare experiences of key populations (LGBTI people and sex workers) in Zimbabwe regarding formal healthcare access and experience of care received.
