Mapping evidence on health promotion in HIV testing among men who have sex with men and transgender women using the social-ecological model and the vulnerability theoretical framework: a scoping review

This study aimed to map the scientific evidence on health promotion in human immunodeficiency virus) HIV testing among men who have sex with men (MSM) and transgender women (TGW) based on the social-ecological model (i.e., individual, organizational and social levels) and the theoretical framework of vulnerability (i.e., individual, social, and programmatic levels). The reviewed studies indicated several barriers to accessing HIV testing (e.g., economic, structural, and bureaucratic) and demonstrated the potential for community approaches to promote greater access to HIV testing and minimize the stigma and discrimination associated with HIV testing, primarily through community leadership and social support networks. The socio-ecological model of health promotion and the vulnerability approach have the potential to contribute to improving HIV testing services by balancing the technical and political power of health services and providers with community participation while considering the social contexts. Therefore, there is a need for reflection on health promotion policies and programs aimed at expanding access to HIV testing among MSM and TGW through interventions that consider the social contexts and cultural perspectives. Moreover, inter-sectoral strategies aimed at improving living conditions and access to fundamental resources for maintaining health and well-being should be considered.

to health promotion deserve to be further systematically investigated.

Background
In 2022, approximately 6 million people worldwide living with HIV (PLHIV) were unaware of their serological status [1].The number of human immunodeficiency virus (HIV) tests performed decreased worldwide between 2020 and 2021 due to the novel coronavirus pandemic.For example, Latin America and the Caribbean had approximately 4,000 fewer diagnoses, and in eastern and southern Africa, approximately 10,000 fewer HIV tests were conducted in 2020 and 2021 than in 2019.European Union (EU) countries reported declining HIV tests performed during 2020 [2].The pandemic notably increased social inequalities aggravated social vulnerability, and created barriers to accessing various health services, substantially affecting historically impoverished and stigmatized populations [3].
The absence of HIV testing represents a significant challenge in controlling the epidemic, as knowledge of the serological status for HIV detection is the gateway to healthcare, including initiating anti-retroviral therapy (ART) [2,[4][5][6][7].ART significantly helps prevent viral transmission because PLHIV on ART with an undetectable viral load do not transmit the virus to others; the socalled "undetectable = untransmissible" [8].
The current UNAIDS targets 95-95-95 to eliminate the HIV epidemic by the year 2025 are as follows: "95% of people living with HIV know their serological status; 95% of people who know their serological status are under anti-retroviral treatment; and 95% of people undergoing anti-retroviral treatment have their viral load suppressed" [9].However, these will only be achieved with increased HIV testing and awareness of one's serological status.
Representing 65% of global HIV infections, men who have sex with men (MSM) and transgender women (TGW) are considered more vulnerable to the HIV epidemic [9,10].Thus, they have a greater need for HIV testing [11][12][13].Studies have shown that the testing frequency is low in this population in some parts of the world [14][15][16].Barriers to expanding test coverage include a low perception of risk, fear of positive testing, concerns about confidentiality and stigma, inconvenience of attending clinics, and long waiting times [17][18][19][20].
In several countries, testing strategies for MSM and TGW are still rooted in a biomedical model, with health professionals' focus restricted to the technological dimension of preventive practices (e.g., testing in health services) and prescription of anti-retroviral drugs such as post-(PEP) and pre-(PrEP) exposure prophylaxis [18,21,22].Generally, these interventions are guided by technical and bureaucratic views, with little flexibility to adapt to socio-cultural perspectives, such as government imposition of programs and funding policies that prevent hiring peer counselors in specific contexts [16,21].Furthermore, there are numerous records of discriminatory practices inside and outside HIV testing services that make accessing them difficult, such as discriminatory attitudes among healthcare service staff or a lack of privacy and confidentiality concerning a patient's serologic status [18,21,23,24].
Therefore, it is necessary to reflect on health promotion policies and programs to expand access to HIV testing among MSM and the TGW through interventions that consider key populations' social contexts and cultural perspectives [16].Moreover, inter-sectoral strategies aimed at improving living conditions and access to fundamental resources for maintaining health and wellbeing should be considered under the auspices of equity and in accordance with the approaches proposed by the International Conferences on Health Promotion [25].
Accordingly, through this scoping review, we aimed to map the scientific evidence on health promotion in HIV testing among MSM and TGW based on the concept of the social-ecological model, which establishes three explanatory levels: (i) the individual level (e.g., individual characteristics such as education, habits and lifestyle, risk perception, and personal beliefs); (ii) the organizational level (e.g., perceptions of control over the environment such as cultural, organizational, and geographical dimensions of services); and (iii) the social level (e.g., community approaches to health promotion and development of well-being [26].Stokols (1996) point out that these levels address elements that can assist in developing and evaluating health promotion programs.In addition, we employed the theoretical framework of vulnerability [27] to better understand how the interrelationships among the individual, organizational, and social levels lead to different outcomes in HIV testing.By bringing together the vulnerability framework and social-ecological model of health promotion, we can acquire an all-encompassing view of the planning of actions at these three equivalent levels, which may help overcome existing limitations in implementing health promotion policies for HIV testing [28].

Materials and methods
This study adopted a scoping review described according to the recommendations of the PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and Explanation [29] on HIV testing among MSM and TGW from a social-ecological approach to health promotion, combined with the theoretical framework of vulnerability (The Checklist for Scoping View is attached as a related file).This study was registered on the Open Science Framework platform (https:// osf.io/ ys359/).

Eligibility criteria
Qualitative and mixed methods studies that described health promotion in HIV testing among MSM and TGW based on the conception of the social-ecological model were included.The data collection of these studies was performed using focus groups and in-depth or semistructured interviews to evaluate HIV testing among MSM and TGW.Abstracts presented at congresses were also included.We excluded narrative, integrative, scoping, rapid or systematic reviews; studies that do not report HIV testing on MSM or TGW; and protocols.No restrictions were imposed on the dates or places of publication (see Fig. 1).

Data source
The search for information was conducted using the electronic databases of the Web of Science, MEDLINE, PubMed, Scopus, Science Direct, Scielo (via the Virtual Health Library), and gray literature.The review was conducted between June 2020 and updated in December 2022.
The list of terms identified in MeSH (medical subject headings) or DeCS (health sciences descriptors) used to search for articles was as follows: "sexual and gender minorities, " "trans people, " "transvestism, " "men who have Fig. 1 Flowchart for the systematic article selection process sex with men, " "rapid test, " "testing strategies, " "anonymous tests, " "serological tests, " "HIV serodiagnosis, " "AIDS serodiagnosis, " "early diagnosis, " "HIV infection, " "HIV infection/diagnosis, " and "HIV." The information search strategy included combining the descriptors and using Boolean indicators "OR" and "AND." The correspondence between Portuguese and Spanish was also used.Furthermore, a manual search was performed on all the included study reference lists to identify potential local studies.

Selection of studies and data extraction
The studies were managed using Mendeley to remove duplicates and were subsequently exported to the Rayyan Qatar Computing Research Institute ® platform to assist the researchers in the eligibility screening process.Two authors independently identified and verified the titles and abstracts of the studies and then performed textual evaluations.In cases of disagreement, a third author resolved the conflicts.
The research team prepared and applied a data extraction spreadsheet (see Supplementary Material 1) to summarize the following data from the studies: reference (name and year of publication of the study) study location (country), title, journal, objectives, population studied, methodology, study scope in relation to the population (MSM and TGW), type of testing creation strategy request, HIV prevalence, barriers and facilitators for HIV testing, main results, and final considerations.
A meta-ethnographic approach comprising six phases was adopted to analyze the articles [30]: 1) definition of the theme and scope of the study; 2) choice of relevant studies through eligibility criteria and evaluation of methodological quality using the Critical Appraisal Skills Program (CASP) score; 3) careful reading of the articles and extraction of primary data or first order constructs (untreated data resulting from interviews, focus groups, or research in general); 4) analyzing the key concepts of the articles and examining these concepts' relationships between studies, extracting the concepts from second order constructs (authors' primary interpretation of the data) and from study themes; 5) producing the constructs from the analysis and comparison of the studies' key concepts, seeking to identify the presence or absence of similarities, and grouping those that stood out or were repeated into categories; and 6) producing a content synthesis, which can be a refutational synthesis or a line of argument synthesis [30,31].

Theoretical framework
The theoretical framework of vulnerability postulates the existence of a "set of aspects that are not only individual but collective and contextual, leading to greater susceptibility to infection and illness and, inseparably, the greater or lesser availability of resources of all kinds to protect against both".Vulnerability analyses consider three interconnected dimensions: individual, programmatic, and social [27].
The socio-ecological model framework proposes an interface among social ecology, behavioral medicine, and public health.It is comprised of theoretical principles that aim to clarify the inter-relationships between individual and environmental factors and their interference health outcomes [26].It offers a variety of methodological concepts and tools for organizing and evaluating health interventions and promotions.Stokols [26] presents three levels of complementary perspectives that could generate analytical categories for health promotion interventions: 1) individual characteristics and behavioral and lifestyle changes (individual level); 2) perceptions of control over the environment, forms of organization of the environment, services, and health systems (organizational level); and 3) socio-ecological analyses of health promotion and community approaches (social level).
Figure 2 links the elements of the theoretical vulnerability framework to the socio-ecological model to understand the conflicts, factors, and interventions that interfere with the barriers and facilitators of HIV testing among MSM and TGW.In this sense, we sought to analyze the relationships between the components of vulnerability (i.e., individual, programmatic, and social) and the socio-ecological levels (i.e., individual, organizational, and social) categorized as interconnected in the three dimensions of individual, programmatic/organizational, and social dimensions and represented as a triangle.The triangle's base represents society and community, the middle health services, and the top individual characteristics, behaviors, and relationships.These dimensions emphasize that individual health care is not only the result of individual actions but also due to a set of interrelationships that exist among individuals, society, culture, and health institutions [26,27,32].
Access to HIV testing responds to social determinants that extend beyond individual dimensions.Thus, it is necessary to adopt a reflective theoretical-methodological approach to identify and analyze the problem in its dynamic totality and to identify and analyze the intersections between the vulnerability contents and structural levels.The left side of the triangle represents the main theoretical perspectives associated with determining health, disease, and care, while the right side shows the main interventions for health promotion in HIV testing (see Fig. 2).
As the individual dimension comprises strategies related to behavioral change for health promotion, it is essential necessary to consider both the quantity and quality of information that individuals possess about the problem, how they can elaborate on this information and incorporate it into their daily repertoire of concerns, and the individual's interests and real possibilities of them transforming these concerns into safe and protective practices.Associated theoretical perspectives, such as the theories of "self-efficacy" and "risk perception" contribute to approaches to healthcare [26,27].
The programmatic/organizational dimension addresses the strategies of environmental and organizational change for health promotion, with theoretical perspectives on organizational development and the quality of the relationship between individuals and accessed services.The environments must be free of discrimination related to 1) HIV, 2) sexual orientation, and 3) gender identity.Moreover, greater accessibility to distinct types of HIV tests is needed.In this sense, the programmatic contents of vulnerability discuss the need to guarantee public and institutional policies and ensure that social resources are made available democratically so that individuals can protect themselves from exposure to HIV and minimize its damage [26,27].
The social dimension addresses adopting cultural change and creating models for strengthening social and community support for healthcare.In this sense, the social component of vulnerability measures the political, economic, cultural, religious, and moral contexts in which an individual is located.Specifically, it postulates the need for access to information, incorporation of this information, and the ability to transform it into practical changes.This component highlights that the ability to manage information depends on the individual and is linked to their access to education (schooling), media, and material resources [26,27].

Data analysis
The data analysis was based on the dimensions constructed and presented in the theoretical model (see Fig. 2).The categories were related to the social-ecological model, including HIV and auto-immunodeficiency syndrome (AIDS) policies and programs.The dimensions of vulnerability were problematized: the individual dimension: individual perceptions about HIV testing; the organizational/programmatic dimension: bureaucratization of HIV testing; and the social dimension: community strategies for HIV testing.

Evaluation of methodological quality
The methodological quality of the primary articles was assessed using CASP [33].The studies were classified into two categories: 1) those with high methodological rigor that complied with 9 out of 10 items and 2) those with moderate methodological rigor that complied with at least 5 of the 10 items.Validation of the article classification was discussed among the researchers [33].

Population and testing strategies analyzed
The reviewed studies analyzed the barriers or facilitators for HIV testing among MSM and TGW or the preferences for HIV testing type and the acceptability of new HIV testing strategies.Concerning self-testing, 34.6% (n = 18) of the studies analyzed the barriers or facilitators of self-testing for MSM, 15.4% (n = 8) for MSM and TGW, and 1.9% (n = 1) for TGW.Regarding conventional tests, 19.2% (n = 10) of the studies analyzed barriers or facilitators in MSM and TGW, 5.7% (n = 3) analyzed only MSM, and 3.8% (n = 2) analyzed only TGW.Regarding rapid testing, 7.7% (n = 4) of the studies analyzed only MSM, and 1.9% (n = 1) analyzed MSM and TGW.For HIV testing mixed methods, 3.8% (n = 2) analyzed the barriers and facilitators in MSM, 1.9% (n = 1) analyzed MSM and TGW and 3.8% (n = 2) explicitly analyzed barriers and facilitators without explaining the testing strategy.

Methodological rigor
Of the 52 articles, 28 (53.8%)fulfilled at least nine of the items proposed by the CASP and were classified as having high methodological rigor, 21 (40.4%)fulfilled between six and eight items, and only three (5.8%)fulfilled 5 of the 10 items evaluated by the CASP.

Social-ecological model: health promotion policies and programs vs. HIV testing strategies
In this category, we present evidence of HIV/AIDS programs that approach or distance themselves from the rationale of health promotion.A health promotion perspective, in this context, refers to the programs and policies to face the HIV/AIDS epidemic, addressing issues beyond the biomedical perspective, as proposed by the social-ecological model (Fig. 2).
Some studies have demonstrated that programs and policies can control the HIV/AIDS epidemic from a health promotion perspective.HIV testing in these contexts was presented as an all-encompassing rationale for different MSM and TGW populations with specific social needs, seeking to eliminate or minimize health inequities and barriers to HIV testing.Programs that incorporate community testing, community leader engagement, peer testing, social support networks, and strengthening of NGOs are particularly notable [17,[34][35][36][37].
Fauk et al. [24] stated that the Indonesian government has been committed to fighting the spread of HIV/AIDS through the establishment of policies and prevention programs, HIV testing, ART, and social support to improve individuals' knowledge concerning HIV and enhance the existing testing programs.
Studies conducted with social networks in African American youth communities [38,39] identified HIV self-testing as a potent strategy to increase the uptake of HIV testing among MSM and TGW.The authors indicated that, in addition to increasing HIV diagnoses, self-testing brings individuals closer to and facilitates their entry into clinical care and treatments such as ART.
Studies have also demonstrated the increasing incorporation of new HIV testing technologies, such as HIV self-testing, in the last decade.In total, 50% of the studies analyzed self-testing and the increasing use of information and communication technologies in health, mobile applications, and online social networks [40][41][42][43][44][45][46].However, the incorporation of new testing technologies and communication strategies has not ensured access to HIV testing or information.For example, the prohibitive cost of HIV testing in some countries is considered a barrier to access.

Vulnerability: understanding HIV testing outcomes
Using the theoretical framework of vulnerability, we analyzed the impact of the presence or absence of health promotion in HIV/AIDS programs and policies and how this interferes with positive or negative outcomes in HIV testing.Table 2 lists the present barriers and facilitators that interfere with HIV testing.
Table 2 presents the barriers and facilitators to HIV testing in the three dimensions of the socio-ecological model, which are presented following the three dimensions of the theoretical model:

Individual dimension
MSM and TGW individuals' perceptions about HIV testing were identified in the individual dimension.The studies that evaluated individual's relationship with the HIV test discussed the acceptability and usability of self-testing.
Barriers for HIV test: perceptions and feelings about HIV testing The main barriers identified for the use of selftesting at the individual level were the technical challenges of performing the HIV test and the fear of a positive result without the immediate presence of a health professional (see Table 2).Additionally, the fear of a positive result and the prohibitive cost of the test were considered barriers to testing in the three types of tests: conventional, self-test, and rapid test [15,18,21,23,42,47,48].
Poor knowledge of testing services and insufficient understanding of the benefits of knowing one's serological status were considered barriers to conventional testing and were related to low educational levels in some studies [18,21,24,49].Other studies showed that individuals with a higher level of education have doubts about the accuracy of the HIV self-test and fear a false negative result owing to the immunological window period of HIV infection [15,19,35,39,50].
Facilitators for HIV test One study pointed out in addition to promoting self-test visibility and increasing user confidence, other strategies, such as providing tutorials on television or social networks on the correct self-test procedure, can be beneficial for target populations [43].

Programmatic and organizational dimension
This dimension analyzed how health services are organized for HIV testing and the organizational structure of health systems and national and local HIV programs of the studies in question.The studies highlighted several structural and bureaucratic barriers to HIV testing and health services and systems, respectively.
Organizational structure of national and local HIV programs Among all the studies analyzed, two published in India [16,18] several individuals did not trust the confidentiality of the results, suffered discrimination from professionals in the field, and were threatened and harassed.Additionally, there was low acceptance of the testing service offered due to the absence of non-invasive testing methods (oral fluid self-testing), long queues, and poor physical facilities.They also verified funding policies preventing the hiring of peer counselors in specific contexts.
A study published in Colombia [21] highlighted bureaucratic barriers in the health system that hinder access to free testing services.According to the study, the HIV testing process is offered annually to MSM individuals and comprises four distinct stages: risk assessment and approval by a physician, pre-test consultation with a nurse or social worker, blood collection for testing, and post-test counseling.This study also notes that individuals needed to move to geographically distant locations at each stage of the testing process and bear displacement costs [21].Difficulty in geographic access to testing services for individuals living in rural areas was also reported [21].For example, a study conducted in Scotland reported difficulty in geographic access to HIV testing for individuals living in rural areas [58].
The presence of bulky packaging involving self-tests was reported to be a barrier as some individuals found it difficult to conceal the self-test inside their jeans pocket without being noticed, which would lead to questions about the nature of the package; for example, when walking on the street [47,59].Two Cambodian studies [42,43] reported users' difficulty in following the HIV selftest instructions because they were not translated into the local language.
New HIV testing strategies Moreover, several studies have shown that unconventional testing strategies were well accepted or were a feasible alternative for offering HIV tests in certain specific contexts and in specific populations.For example, the provider-initiated testing and counseling (PITC) strategy proved effective in diagnosing early cases of HIV in MSM and TGW immigrants living in Spain; besides improving these individuals' access to HIV testing, this strategy also minimized the stigma surrounding testing [60].
Like the PITC strategy, a mixed-method study conducted in New York in 2019 among Black and Hispanic or Latino MSM found that the implementation of the Opt-Out law testing as a routine to offer HIV testing in health services could increase the uptake of HIV testing and improve accessibility to HIV testing, and that the convenience of being tested in a routine consultation and knowing one's HIV status stimulated preventive behaviors.However, approximately 30% of the individuals interviewed in the study reported feeling "threatened" or stigmatized by this testing law owing to concerns about the privacy and confidentiality of HIV test results [61].
Testing strategies conducted in mobile vans in Australia expanded the availability of HIV testing in various places and times and facilitated the scheduling of tests and the establishment of communication with individuals through social media.Conversely, difficulties were observed in adopting a good aesthetic for the vehicles to attract individuals to the vans for testing.Additionally, some researchers were concerned about the personal safety of individual volunteers who provided support and testing of HIV in their network of contacts and in the community (called "peer-testers") during the night in isolated and unknown areas [62].
Some studies discussed the "partner testing" strategy [63][64][65][66][67] from two perspectives: testing couples who had steady partners and testing casual partners and sex workers' clients.However, although couples with steady partners generally accepted this strategy, it was considered challenging for some TGWs with casual or transactional partners due to the possibility of violence against mainly because HIV testing was not acceptable for these partners [65,66].

Social dimension: social support, community strategies and community leaders
Finally, the social dimension leads to community strategies for HIV testing.Several studies have described the strategies of distribution of peer tests through social support networks or testing in NGOs as important for increasing HIV testing rates, especially among young black MSM and TGW [24,34,35].
Social support among MSM peers plays a significant role in increasing the intention to participate in HIV testing services [24].Confidence in social support networks is described as a facilitator; for example, for performing the HIV self-test [17].Having social support from friends in the same social network during the HIV self-test was found to counterbalance the absence of professional counseling during and after the test and encourage individuals to regularly test themselves and seek health care [35].
Studies have also shown that the use of community strategies had positive results in the implementation of HIV testing services in culturally stigmatizing contexts, such as in some places in India and the Philippines [18,43].Thus, the main interventions for health promotion in relation to HIV testing based on the socio-ecological model are models of cultural changes in health, promotion of community health, initiatives of non-discriminatory public policies for strengthening NGOs, and community testing programs (see Fig. 2).
Regarding the availability of HIV tests and the role of community leaders, several studies have shown that bureaucratically institutionalized test arrangements in health institutions and services hindered access to HIV testing, whereas the participation of community services and NGOs and support from community leaders facilitated the use of self-testing and increased individuals' confidence [21, 24, 34, 36-38, 61, 68].

Discussion
Through the reviewed studies, the principal elements of three dimensions (i.e., individual, programmatic/organization, and social) were analyzed.The ecological model and the vulnerability framework, as well as some synergistic and complementary relationships between the dimensions were also examined.Furthermore, facilitators and barriers to HIV testing among MSM and TGW were identified in the three dimensions.
Some studies have shown that HIV testing services, which seek to logically promote health, operationalize HIV testing in a more comprehensive, inter-sectoral, and capillary way and a closer and more dialogue-driven manner with the community.In a larger discussion, Mol (2008) [69] addresses this kind of issue as the transposition of the "logic of choice, " centered on the provision of interventions and health technologies, to the "logic of care, " centered on the openness to knowing and discussing the concrete situations faced by people, as well on the refusal to reduce care to a "product" to be delivered.This transposition involves recognizing the coexistence of different "logics" that often generate contradictions and ambiguities in care practices and are commonly faced by people who hope to balance pleasure and risk control in sexual practices with a view to not only safeguard health and safety but also search for the meaning of life.As Vasconcelos et al. [70] explain, we should think of "HIV/STI prevention from the perspective of the logic of care, and thus, as a process that is not linear but dynamic, open, fluid, and erratic with multiple interactions and effects." In this sense, it is vital to promote cultural changes in health systems, minimize barriers (both organizational and relational), act to reverse inequalities and inequities historically present in HIV testing [21, 24, 34, 36-38, 61, 68], and seek to balance power relations for the expansion of more dialogical institutional communicative health practices.It is good to remember that the paths opened by communicative technologies can contribute to this increase [69].
Discussing and operationalizing HIV testing "out of the box" in the health sector allows us to understand health promotion in its expanded conception of the health-disease process, incorporating community participation and the inter-sectoral nature of the actions performed by HIV testing programs.Thus, commitment to health equity and human rights is reaffirmed by recognizing the "collective rights of subjects" [69] that are shaped by the different "key populations" [72].
Conversely, the reviewed studies also identified that some health services and systems remain ill-prepared to perform HIV testing among MSM and TGW based on an expanded rationale for health promotion.Articles produced in India, Africa, Colombia, and Cambodia showed that the health systems of these countries still have organizational and structural deficits and bureaucratic barriers (technocratic actions that are rigid and insufficiently consider the perspectives of users and operate at the level of an "over the counter" health service) [71] with regard to HIV testing [16,18,21,42,43].
Accordingly, health systems need to address barriers in HIV testing and "rebuild" their national HIV programs to incorporate an expanded conception of health, strengthen human rights, create enabling environments free of discrimination and violence for MSM and TGW individuals, strengthen inter-sectoral and community approaches to HIV testing and individual autonomy, and encourage individuals to self-test.
Successful HIV prevention and awareness is a matter of enabling new HIV testing based on the recognition of the political power of communities and individuals involved in the decision-making processes.It is about expanding the conception of HIV testing beyond a prevention mechanism and combining it with changes in environments that provide autonomy and empowerment to subjects, thereby facilitating their access to and use of HIV testing.Thus, the greater the efforts made to improve the programs associated with existing social resources, the greater the chances of strengthening individuals in the face of the HIV epidemic and minimizing barriers to testing [27].

Conclusion
Based on the findings of the studies and discussions presented above, we conclude that a "reconstruction" of HIV testing in its governmental, sectoral, and community contexts is necessary.It is a matter of situating the HIV test in the context of social interactions and expanding it to an inter-sectoral and community perspective within a broader view of health based on overcoming the traditional biomedical model rooted in health services, which reflects a testing process that includes political, programmatic, and socio-cultural aspects beyond one that is exact, bureaucratic, and regulated from a biomedical perspective.
We need greater democratization of HIV testing, minimization of barriers, ease of access to and use of tests, empowerment of individuals and communities, recognition of their rights, and guarantees of equity.HIV testing based on the health promotion model reinforces the idea that the need for individuals to respond to the transformation of practices is not limited only to the individual and private matrix but also extends to social subjects within the public sphere of social life.
Therefore, we reiterate that health promotion has the potential to contribute to a global change in testing services so that services incorporate equitable benchmarks that promote health, strengthen subjects in the face of epidemics, and recognize and support the political power of communities.This study was supported by Conselho Nacional de Desenvolvimento Científico e Tecnológico-CNPq/Brazil (#443116/2019-9).The funders had no role in study design, study selection and data extraction, data analysis, decision to publish, or preparation of the manuscript.
