Introduction
According to the 2021 UNAIDS report, there were 37.7 million people globally living with HIV (PLHIV) globally in 2020, 36.0 million of whom were adults and 1.7 million children aged 0–14 years, while 53% of all PLHIV were women and girls [
1]. Globally, adolescent girls and young women (AGYW), aged 15–24 years, have 60% higher HIV infection compared to adolescent boys and young men of the same age [
2]. Furthermore, around 1.5 million people were newly infected with HIV and women and girls accounted for 50% of these new infections. Every week, around 5,000 AGYW become infected with HIV [
1].
In Sub-Saharan Africa, AGYW represent 10% of the total population but accounts for about 25% of all HIV infections [
3]. Additionally, six in seven new HIV infections among adolescents aged 15– 19 years are among girls [
1]. In Eastern and Southern Africa, there were 2.4 HIV infections among AGYW for every one infection among boys and young men of the same age [
4]. Adolescent girls and young women remain at a higher risk of HIV infection.
HIV counselling and testing services are essential for HIV prevention, treatment, care, and support [
5]. In 2016, the United Nations (UN) declared to end AIDS at the end of 2020 [
6]. The declaration endorsed the 90–90-90 targets, requiring at least 90% of PLHIV would know their status, 90% of these would be on antiretroviral treatment (ART), and 90% of those on ART would achieve viral load suppression (VLS) [
6]. Increasing access to and uptake of HIV testing is critical to achieving the first and the two corresponding targets [
7]. The World Health Organization (WHO) also recommends annual testing in high HIV prevalent settings [
7,
8].
Rwanda faces an HIV epidemic with an estimated prevalence in the population aged 15–49 years of approximately 3% in 2010 [
9]. The prevalence of HIV among adolescent girls and young women in Rwanda is 3.7% [
9]. HIV prevalence discrepancy by gender is particularly marked among young people, where infection among young women of ages 20–24 is five times higher than in men of the same age [
10,
11]. The country has made extensive gains in HIV testing and counselling (HTC) as its national strategic plan (NSP) reports an 83.8% rate of self-reported HIV testing among HIV-positive adults aged 15–64 years, specifically 85.6% of HIV-positive women and 80.4% of HIV-positive men [
9], thereby showing higher HIV testing among women than men.
Numerous studies have documented factors associated with HIV testing, such as gender, age, education level, pregnancy, geographical location, marital status, and the number of sexual partners [
5,
12,
13]. Studies in several countries have found varied HIV testing rates among young women such as in Nigeria (12%), Uganda (26.5%), Kenya (27.7%), and Rwanda (40%) [
5]. There remains an unmet need for effective HIV prevention strategies among AGYW compared to their male peers and understanding factors associated with self-reported HIV testing could aid in improving these strategies. This study explored the prevalence and factors associated with self-reported HIV testing among AGYW in Rwanda using 2019/2020 Demographic and Health Survey (DHS) data.
Discussion
The objective of this paper was to determine the prevalence and risk factors for self-reported HIV testing among AGYW, aged 15 to 24 years, in Rwanda using the 2019/2020 Demographic and Health Survey (DHS) data. To do this, we analysed data from 5,732 AGYW which gave a prevalence of 55.4% of self-reported HIV testing among Rwandese AGYW. This is lower than the 78% reported in the 2019/2020 DHS report for the 15–49 year age group. This is probably because women aged 15-49 years have a higher proportion of those with a history of pregnancy than the 15–24 years age group. The HIV testing rates among pregnant women are generally higher since the women are tested for HIV during antenatal care. Although the 2019/2020 DHS reports that 96.1% of 15–24-year-old youths know where to get tested, 45% of the 5,732 AGYW still did not get tested; this may suggest that knowledge of where to get tested does not imply that they would actually test for HIV. The proportion of those testing is also lower because the 96.1% includes both males and females. A logistic regression model accounting for survey weights was performed and findings from the adjusted model show that being in the 20–24 year age group, living with a man, urban-dwelling, higher education, employment, economic stability, access to media, history of pregnancy, ever having sex, HIV non-discriminatory attitudes, and having comprehensive HIV knowledge, were significantly associated with self-reported HIV testing.
We found a strong association between pregnancy and self-reported HIV testing. This could mainly be attributable to the wide access to HIV testing among pregnant women attending antenatal clinic (ANC) visits [
16]. Several studies have also found this association [
13,
16,
17]. It is important to test for HIV when pregnant as this allows for those who test HIV positive to be enrolled for interventions that prevent mother-to-child transmission of HIV and also to initiate ART.
AGYW aged 20–24 years had higher odds of HIV testing compared to those aged 15–19 years. The age group 20–24 has more information on sexual matters and is more likely to go for HIV testing than the 15–19-year-olds. This is in line with other previously published studies from Zambia, South Africa, and Tanzania [
13,
18,
19]. The AGYW who lived with a man were more likely to test for HIV and this could be due to their possibly high sexual activities, hence they are at higher risk of HIV and other sexually transmitted diseases, for which they would visit the healthcare facilities and would also be allowed to test for HIV [
20]. Other studies have found similar results, for example in South Africa by Jooste et al. 2020 [
21] and in Tanzania by Mahande et al. 2019 [
22].
AGYW from urban areas had significantly higher odds for HIV testing compared to their counterparts from rural areas. This could be explained by the easy access to sexual and reproductive health and rights (SRHR) and HIV services in primary healthcare facilities in urban areas. In addition, individuals in the urban areas are modernized and may not be influenced by culture or the stigma that follows when one decides to go for HIV testing as in the rural areas [
23]. This finding is supported by various other studies in South Africa, Ethiopia, and Nigeria [
5,
24,
25]. We also found that compared to those from the Eastern region of Rwanda, the AGYW from Kigali, and the Northern region were significantly more likely to test for HIV. There is an increase in urbanization caused by demographic shifts and decentralization in the Northern Province. It has also been noted that knowledge and attitudes towards HIV are better than at the national level for the Northern Province [
23,
26].
As the education level increased, the odds of HIV testing also increased and this is in agreement with previous studies [
27‐
29]. Those with higher education are also most likely to have higher knowledge of HIV, which we have also found to be associated with testing for HIV. Those who were employed were more likely to have tested for HIV, which can be explained by their chance of exposure to massive HIV awareness events at the workplace or around them. We also found that coming from rich households was associated with HIV testing. This is probably because the poor may not afford transport costs to the HIV testing centres even though HIV testing is free in Rwanda. The rich have more access to all forms of media and therefore are likely to have more knowledge on HIV testing. Additionally, the poor may be more preoccupied with meeting their daily needs and HIV testing may not be a priority for them. Other studies (see Jooste et al. 2020 [
21], Cemin et al. 2012 [
30], Treves-Kagan et al. 2017 [
31], Matovu et al. 2013 [
32], Ibrahim et al. [
24], Molla et al. [
33], Menon et al. [
34]) also found that wealthy individuals are more likely to be tested for HIV as compared to poor individuals.
Our findings also show that AGYW who had access to at least one media platform at least once a week (newspapers, TV, or radio) were more likely to have tested for HIV. It is most likely that the local HIV/AIDS organizations and the Rwanda Ministry of Health also disseminate HIV information via newspapers, radios, and TVs. This can sensitise the AGYW on the importance of HIV testing and provide information on where to get HIV tested. This has also been found by other studies from Ethiopia [
33] and Zambia [
34].
Those who ever had sex were more likely to have tested for HIV. This is not surprising as most HIV transmissions happen through sexual intercourse. This can also be tied to inconsistent condom use [
13], which is associated with HIV testing. The fear that one may have acquired HIV after having unprotected sex can influence an individual to go for HIV testing.
This study is not without limitations. Since this is a secondary data analysis of a cross-sectional study, we cannot infer a causal relationship between the risk factors and the self-reported HIV testing outcome. In addition, the data set lacked some known risk factors for HIV testing; for instance, religious beliefs can influence the decision for HIV testing. We also could not determine whether some HIV sexual risk behaviours such as inconsistent condom use, multiple sexual partnerships, and inter-generational sex partnerships, were associated with HIV testing because our model could not converge when these were included. Moreover, the data on gender-based violence (GBV) had a lot of missing data. This may be due to the sensitive nature of the subject that could have underestimated the association between intimate partner violence and/or GBV with testing for HIV.
There are also strengths of this study. This study is a secondary data analysis of a recent large sample of 5,732 Rwandese AGYW with data from DHS, which is a rigorously conducted nationally representative population-based cross-sectional survey. All analyses done on the survey data were adjusted using survey weights.
Conclusion
In summary, we found an unmet need for HIV testing among adolescent girls and young women in Rwanda based on the 2019/2020 DHS data. We also found that being 20-24 years old, living with a man, urban-dwelling, higher education, employment, economic stability, access to media, history of pregnancy, ever having sex, and having comprehensive HIV knowledge were associated with HIV testing. We, therefore, recommend that the Rwandan Ministry of Health and other stakeholders incorporate our determinants of self-reported HIV testing in creating awareness for HIV testing among youths. We also recommend qualitative studies to further describe the barriers and facilitators of self-reported HIV testing among adolescent girls and young women in Rwanda.
