A sex-role-preference model for HIV transmission among men who have sex with men in China

Background

Men who have sex with men (MSM) are much more likely to be infected with HIV than the general population. China has a sizable population of MSM, including gay, bisexual men, money boys and some rural workers. So reducing HIV infection in this population is an important component of the national HIV/AIDS prevention and control program.

Methods

We develop a mathematical model using a sex-role-preference framework to predict HIV infection in the MSM population and to evaluate different intervention strategies.

Results

An analytic formula for the basic reproduction ratio R₀ was obtained; this yields R₀ = 3.9296 in the current situation, so HIV will spread very fast in the MSM population if no intervention measure is implemented in a timely fashion. The persistence of HIV infection and the existence of disease equilibrium (or equilibria) are also shown. We utilized our model to simulate possible outcomes of antiretroviral therapy and vaccination for the MSM population. We compared the effects of these intervention measures under different assumptions about MSM behaviour. We also found that R₀ is a decreasing function of the death rate of HIV-infected individuals, following a power law at least asymptotically.

Conclusion

HIV will spread very fast in the MSM population unless intervention measures are implemented urgently. Antiretroviral therapy can have substantial impact on the reduction of HIV among the MSM population, even if disinhibition is considered. The effect of protected sexual behaviour on controlling the epidemic in the MSM population largely depends on the sex-ratio preference of different sub-populations.

     

Transition from HIV control to HIV elimination in Switzerland

Purpose

This article proposes a strategy for Switzerland to change the goal from HIV control to HIV elimination. In Switzerland, HIV treatment is well organized and available for all with good access.

Methods

An important challenge that obstructs prevention is the new infections originating from people who are unaware of their status. Since the majority of new infections in Switzerland are within the group of men who have sex with men (MSM), this strategy targets MSM who do not know their HIV status and engage in risky sexual behavior.

Results

The strategy focuses on three pillars: collaboration and leadership, key actions and important indicators. To guide this effort, we proposed a task force to be responsible for leading this strategy. Its actions are centered around four aspects: learn from MSM, promote and facilitate testing, and include PrEP and PEP in the prevention package together with partner information. This article also provides important indicators that must be measured to inform the task force and to adapt or strengthen the strategy to reach the goal.

Conclusion

Reaching the right persons and offering the right “prevention package” are the key challenges for Switzerland to be among the first countries to eliminate HIV transmission.

     

Should Men who have sex with Men be allowed to donate blood in Israel?

Background

The present permanent deferral policy in Israel for MSM was established in 1977 and was based on the previous (now outdated) USA Food and Drug Administration standards. This study analyses epidemiological data regarding blood donations among MSM, in order to estimate the risk for HIV transfusion transmitted infection (TTI) if the policy is changed to allow at-risk MSM to donate blood.

Methods

An Excel based spreadsheet model integrated demographic, epidemiological data from the HIV National Register, laboratory, blood donation and testing data in order to calculate TTI due to false-negatives in known HIV+ donors, windows period donations, asymptomatic carriers and laboratory misclassification errors. A sensitivity analysis of our estimated TTIs for deferral periods for MSM was performed based on a literature review regarding this overall policy issue worldwide.

Results

MSM in Israel have a considerably higher relative risk (RR) of both prevalence (115) and incidence (143) of being HIV+ than persons without a risk factor. Allowing MSM to donate blood, without any deferral period, will add an additional five HIV TTI cases over the next decade. Imposition of a 1 or 5 years deferral of abstinence will increase the number of HIV TTI cases only by 0.10 and 0.05 cases, respectively.

Conclusion

A 1 year deferral period for blood donations from MSM in Israel is recommended.

     

Mental health care providers' suggestions for suicide prevention among people with substance use disorders in South Africa: a qualitative study

Background

People with substance use disorders (PWSUDs) are a clearly delineated group at high risk for suicidal behaviour. Expert consensus is that suicide prevention strategies should be culturally sensitive and specific to particular populations and socio-cultural and economic contexts. The aim of this study was to explore mental health care providers' context- and population-specific suggestions for suicide prevention when providing services for PWSUDs in the Western Cape, South Africa.

Methods

Qualitative data were collected via in-depth, semi-structured interviews with 18 mental health care providers providing services to PWSUDs in the public and private health care sectors of the Western Cape, South Africa. Data were analysed inductively using thematic analysis.

Results

Participants highlighted the importance of providing effective mental health care, transforming the mental health care system, community interventions, and early intervention, in order to prevent suicide amongst PWSUDs. Many of their suggestions reflected basic principles of effective mental health care provision. However, participants also suggested further training in suicide prevention for mental health care providers, optimising the use of existing health care resources, expanding service provision for suicidal PWSUDs, improving policies and regulations for the treatment of substance use disorders, provision of integrated health care, and focusing on early intervention to prevent suicide.

Conclusions

Training mental health care providers in suicide prevention must be augmented by addressing systemic problems in the provision of mental health care and contextual problems that make suicide prevention challenging. Many of the suggestions offered by these participants depart from individualist, biomedical approaches to suicide prevention to include a more contextual view of suicide prevention. A re-thinking of traditional bio-medical approaches to suicide prevention may be warranted in order to reduce suicide among PWSUDs.

     

Ein Serious Game für Führungskräfte im Pflegebereich

Background

The nursing sector is characterized by high sick leave and fluctuation rates due to work-related stress. There is a need to raise manager’s awareness in the care sector for goal-oriented operational health management.

Objectives

Is a serious game a suitable instrument to change nursing care managers’ behaviors and attitudes and increase their knowledge regarding prevention and health promoting management behavior?

Materials and methods

Preliminary investigation into the stress of care providers, evaluation of the initial situation in nursing care services, conception of a serious game including training concept, testing and evaluation in the field.

Results

In most companies health promotion is not perceived as important (74%); thus, it is expected that “Serious Games for Health” (SGH) will be an effective and suitable instrument to train managers regarding preventive and health promoting management behavior.

Conclusions

Operational health management should be anchored as a management task in the nursing care sector. The innovative educational concept “Stress-Rekord” can counteract multifactorial stress in the workplace.

     

Condoms and sexual health education as evidence: impact of criminalization of in-call venues and managers on migrant sex workers access to HIV/STI prevention in a Canadian setting

Background

Despite a large body of evidence globally demonstrating that the criminalization of sex workers increases HIV/STI risks, we know far less about the impact of criminalization and policing of managers and in-call establishments on HIV/STI prevention among sex workers, and even less so among migrant sex workers.

Methods

Analysis draws on ethnographic fieldwork and 46 qualitative interviews with migrant sex workers, managers and business owners of in-call sex work venues in Metro Vancouver, Canada.

Results

The criminalization of in-call venues and third parties explicitly limits sex workers’ access to HIV/STI prevention, including manager restrictions on condoms and limited onsite access to sexual health information and HIV/STI testing. With limited labour protections and socio-cultural barriers, criminalization and policing undermine the health and human rights of migrant sex workers working in –call venues.

Conclusions

This research supports growing evidence-based calls for decriminalization of sex work, including the removal of criminal sanctions targeting third parties and in-call venues, alongside programs and policies that better protect the working conditions of migrant sex workers as critical to HIV/STI prevention and human rights.

     

Key populations and human rights in the context of HIV services rendition in Ghana

Background

In line with its half century old penal code, Ghana currently criminalizes and penalizes behaviors of some key populations – populations deemed to be at higher risk of acquiring or transmitting Human Immunodeficiency Virus (HIV). Men who have sex with men (MSM), and sex workers (SWs) fit into this categorization. This paper provides an analysis of how enactment and implementation of rights-limiting laws not only limit rights, but also amplify risk and vulnerability to HIV in key and general populations. The paper derives from a project that assessed the ethics sensitivity of key documents guiding Ghana’s response to its HIV epidemic. Assessment was guided by leading frameworks from public health ethics, and relevant articles from the international bill of rights.

Discussion

Ghana’s response to her HIV epidemic does not adequately address the rights and needs of key populations. Even though the national response has achieved some public health successes, palpable efforts to address rights issues remain nascent. Ghana’s guiding documents for HIV response include no advocacy for decriminalization, depenalization or harm reduction approaches for these key populations. The impact of rights-restricting codes on the nation’s HIV epidemic is real: criminalization impedes key populations’ access to HIV prevention and treatment services. Given that they are bridging populations, whatever affects the Ghanaian key populations directly, affects the general population indirectly.

Summary

The right to the highest attainable standard of health, without qualification, is generally acknowledged as a fundamental human right. Unfortunately, this right currently eludes the Ghanaian SW and MSM. The paper endorses decriminalization as a means of promoting this right. In the face of opposition to decriminalization, the paper proposes specific harm reduction strategies as approaches to promote health and uplift the diminished rights of key populations. Thus the authors call on Ghana to remove impediments to public health services provision to these populations. Doing so will require political will and sufficient planning toward prioritizing HIV prevention, care and treatment programming for key populations.

     

Faith leaders’ messaging is essential to enhance HIV prevention among black Americans: results from the 2016 National Survey on HIV in the black community (NSHBC).

Background

To investigate whether religious service attendance and faith leaders’ messages about HIV and same-sex relationships are associated with acceptance of HIV prevention strategies.

Methods

Multivariable Poisson regression assessed whether attending religious services, faith leaders’ messages about HIV and same-sex relationships, and supportiveness of those messages were associated with HIV testing, as well as knowledge of and willingness to use pre-exposure prophylaxis (PrEP) among 868 Black Americans [45% men; M (SD)?=?34 (9) years-old] in the 2016 National Survey on HIV in the Black Community, USA.

Results

Participants who reported attending services monthly and/or hearing faith leaders’ messages that were supportive of same-sex relationships had a significantly higher likelihood of willingness to use PrEP (adjusted Rate Ratio[ARR]?=?1.76; 95% confidence interval [CI]?=?1.09, 2.48) and aRR?=?2.19; 95% CI?=?1.35, 3.55, respectively), independent of HIV risk. Homophobia was significantly associated with higher likelihood of being aware of PrEP and testing for HIV testing in the past 12?months.

Conclusions

Faith leaders’ messaging can influence Black Americans’ perceptions and uptake of HIV prevention strategies. Faith institutions and faith leaders should be involved in designing and disseminating HIV prevention strategies.

     

The readiness of the national health laboratory system in supporting care and treatment of HIV/AIDS in Tanzania

Background

Strong health laboratory systems and networks capable of providing high quality services are critical components of the health system and play a key role in routine diagnosis, care, treatment and disease surveillance. This study aimed to assess the readiness of the national health laboratory system (NHLS) and its capacity to support care and treatment of HIV/AIDS in Tanzania.

Methods

A documentary review was performed to assess the structure of the health system with reference to the status and capacity of the NHLS to support HIV diagnosis. Key informant interviews were also held with laboratory staff in all levels of the health care delivery system in four regions with different levels of HIV prevalence. Information sought included availability and utilization of laboratory guidelines, quality and the capacity of laboratories for diagnosis of HIV.

Results

The findings indicate that a well-established NHLS was in place. However, the coordination of HIV laboratory services was found to be weak. Forty six respondents were interviewed. In most laboratories, guidelines for HIV diagnosis were available but health care providers were not aware of their availability. Utilization of the guidelines for HIV diagnosis was higher at national level than at the lower levels. The low level of awareness and utilization of guidelines was associated with inadequate training and supervision. There was a shortage of human resource, mostly affecting the primary health care level of the system and this was associated with inequity in employment and training opportunities. Laboratories in public health facilities were better staffed and had more qualified personnel than private-owned laboratories.

Conclusion

Tanzania has a well established national health laboratory network sufficient to support HIV care and treatment services. However, laboratories at the primary health care level are constrained by inadequate resources and operate within a limited capacity. Improving the laboratory capacity in terms of number of qualified personnel, staff training on the national guidelines, laboratory diagnostic tools and coordination should be given a higher priority.

     

A comprehensive review of HIV/STI prevention and sexual and reproductive health services among sex Workers in Conflict-Affected Settings: call for an evidence- and rights-based approach in the humanitarian response

Background

While the conditions in emergency humanitarian and conflict-affected settings often result in significant sex work economies, there is limited information on the social and structural conditions of sex work in these settings, and the impacts on HIV/STI prevention and access to sexual and reproductive health (SRH) services for sex workers. Our objective was to comprehensively review existing evidence on HIV/STI prevention and access to SRH services for sex workers in conflict-affected settings globally.

Methods

We conducted a comprehensive review of all peer review (both epidemiological and qualitative) and grey literature published in the last 15 years (2000–2015), focusing on 1) HIV/STI vulnerability or prevention, and/or 2) access to SRH services for sex workers in conflict-affected settings. Five databases were searched, using combinations of sex work, conflict/mobility, HIV/STI, and SRH service terms. Relevant peer-reviewed and grey literature were also hand-searched, and key papers were cross-referenced for additional material.

Results

Five hundred fifty one records were screened and 416 records reviewed. Of 33 records describing HIV/STI prevention and/or access to SRH services among sex workers in conflict-affected settings, 24 were from sub-Saharan Africa; 18 studies described the results of primary research (13 quantitative, 3 qualitative, 2 mixed-methods) and 15 were non-primary research (e.g., commentaries, policy reports, programmatic manuals). Available evidence indicated that within conflict-affected settings, SWs’ capacity to engage in HIV/STI prevention and access SRH services is severely undermined by social and structural determinants including widespread violence and human rights violations, the collapse of livelihoods and traditional social structures, high levels of displacement, and difficulties accessing already scant health services due to stigma, discrimination and criminalization.

Discussion/Conclusions

This review identified significant gaps in HIV/STI and SRH research, policy, and programming for conflict-affected sex workers, highlighting a critical gap in the humanitarian response. Sex worker-informed policies and interventions to promote HIV/STI prevention and access to HIV and SRH services using a rights-based approach are recommended, and further research on the degree to which conflict-affected sex workers are accessing HIV/STI and SRH services is recommended.A paradigm shift from the behavioural and biomedical approach to a human rights-based approach to HIV/STI prevention and SRH is strongly recommended.

     

Community-based prevention leads to an increase in condom use and a reduction in sexually transmitted infections (STIs) among men who have sex with men (MSM) and female sex workers (FSW): the Frontiers Prevention Project (FPP) evaluation results

Background

India has an estimated 2.0 million to 3.1 million people living with HIV; it has the highest number of HIV-positive people in Asia and ranks third in the world. The Frontiers Prevention Project (FPP) was implemented in 2002 to conduct targeted prevention intervention geared towards female sex workers (FSW) and men who have sex with men (MSM) in the state of Andhra Pradesh (AP). This paper reports the overall changes in behaviour and STI outcomes between 2003/4 and 2007 and also describes the changes attributed to the FPP.

Methods

The evaluation used two cross-sectional surveys among MSM and FSW at 24 sites in AP. Surveys were implemented using a similar methodology. Univariate analyses were conducted by comparing means: baseline vs. four-year follow-up and FPP vs. non-FPP. For both MSM and FSW, random and fixed-effects logit regression models at the site level were estimated for condom use with last partner, syphilis sero-positivity and HSV 2 sero-positivity. In addition, for FSW we estimated models for condom use with regular partner, and for MSM we estimated models for condom use with last female partner.

Results

Among MSM, fixed-effects analysis revealed that FPP was positively correlated with the probability of condom use with last female sexual partner and negatively correlated with the individual probability of sero-positivity to syphilis and HSV 2. Among FSW, the FPP intervention was significantly correlated with increased condom use with regular partners and with lower probability of STI sero-positivity.

Discussion

Important changes in behaviours related to an increase in prevention activities translated to reductions in STI sero-prevalence in AP, India. In contrast with non-FPP sites, the FPP sites experienced an intense community approach as part of the FPP intervention, and the general increase in condom use and its effect on STI sero-prevalence reflected the efficacy of these intense prevention activities focused on key populations in AP.

     

Men’s knowledge and attitudes about cervical cancer screening in Kenya

Background

A number of studies have identified male involvement as an important factor affecting reproductive health outcomes, particularly in the areas of family planning, antenatal care, and HIV care. As access to cervical cancer screening programs improves in resource-poor settings, particularly through the integration of HIV and cervical cancer services, it is important to understand the role of male partner support in women’s utilization of screening and treatment.

Methods

We administered an oral survey to 110 men in Western Kenya about their knowledge and attitudes regarding cervical cancer and cervical cancer screening. Men who had female partners eligible for cervical cancer screening were recruited from government health facilities where screening was offered free of charge.

Results

Specific knowledge about cervical cancer risk factors, prevention, and treatment was low. Only half of the men perceived their partners to be at risk for cervical cancer, and many reported that a positive screen would be emotionally upsetting. Nevertheless, all participants said they would encourage their partners to get screened.

Conclusions

Future interventions should tailor cervical cancer educational opportunities towards men. Further research is needed among both men and couples to better understand barriers to male support for screening and treatment and to determine how to best involve men in cervical cancer prevention efforts.

     

Neues zur Gesundheitsförderung und Prävention im Betrieb

Background

The new Prevention Law includes important starting points to strengthen and to further develop occupational health promotion and prevention practices in Germany. A major impetus lies in the encouragement of specific and better collaboration of social insurance and other health policy players, in establishing corresponding structures and in the rearrangement of the financial basis.

Aims

The Prevention Law strengthens the development of health insurance services with respect to content and systematic orientation and evaluation.

Results

Opportunties for systematic development of different approaches and services in health promotion and prevention are fostered through the Prevention Law. It covers rules for intersectoral cooperation with the occupational safety and health system, which have been long overdue; finally, it aims at reducing gender inequality with regard to health promotion and prevention.

     

Increasing sexually transmitted infection rates in young men having sex with men in the Netherlands, 2006–2012

Background

Men having sex with men (MSM) remain the largest high-risk group involved in on-going transmission of sexually transmitted infections (STI), including HIV, in the Netherlands. As risk behaviour may change with age, it is important to explore potential heterogeneity in risks by age. To improve our understanding of this epidemic, we analysed the prevalence of and risk factors for selected STI in MSM attending STI clinics in the Netherlands by age group.

Methods

Analysis of data from the national STI surveillance system for the period 2006–2012. Selected STI were chlamydia, gonorrhoea, infectious syphilis and/or a new HIV infection. Logistic regression was used to identify factors associated with these selected STI and with overall STI positivity. Analyses were done separately for MSM aged younger than 25 years and MSM aged 25 years and older.

Results

In young MSM a significant increase in positivity rate was seen over time (p?<?0.01), mainly driven by increasing gonorrhoea diagnoses, while in MSM aged 25 and older a significant decrease was observed (p?<?0.01). In multivariate analyses for young MSM, those who were involved in commercial sex were at higher risk (OR: 1.5, 95% CI: 1.2-1.9). For MSM aged 25 years and older this was not the case. Having a previous negative HIV test was protective among older MSM compared to those not tested for HIV before (OR: 0.8, 95% CI: 0.8-0.8), but not among younger MSM.

Conclusions

MSM visiting STI clinics remain a high-risk group for STI infections and transmission, but are not a homogenous group. While in MSM aged older than 25 years, STI positivity rate is decreasing, positivity rate in young MSM increased over time. Therefore specific attention needs to be paid towards targeted counselling and reaching particular MSM sub-groups, taken into account different behavioural profiles.

     

The contributions and future direction of Program Science in HIV/STI prevention

Background

Program Science is an iterative, multi-phase research and program framework where programs drive the scientific inquiry, and both program and science are aligned towards a collective goal of improving population health.

Discussion

To achieve this, Program Science involves the systematic application of theoretical and empirical knowledge to optimize the scale, quality and impact of public health programs. Program Science tools and approaches developed for strategic planning, program implementation, and program management and evaluation have been incorporated into HIV and sexually transmitted infection prevention programs in Kenya, Nigeria, India, and the United States.

Conclusion

In this paper, we highlight key scientific contributions that emerged from the growing application of Program Science in the field of HIV and STI prevention, and conclude by proposing future directions for Program Science.

     

In-school adolescents’ knowledge,access to and use of sexual and reproductive health services in Metropolitan Kumasi,Ghana

Objective

Problematic access to and use of sexual and reproductive health (SRH) services potentially endanger the well-being of adolescents and retards progress towards attainment of United Nations health-related Sustainable Development Goals. Drawing on a qualitative research approach, this paper examines the level of SRH-related knowledge, service access and use among school-going adolescents in Kumasi Metropolis, Ghana.

Methods

We conducted 12 focus group discussions and 18 in-depth interviews with 132 in-school adolescents and six healthcare providers in the metropolis. A thematic analytical framework was used to analyse the data.

Results

Findings suggest that the majority of adolescents had good knowledge about the available SRH services, with an emphasis on the different forms of contraceptives. However, the use of the various SRH services was challenging and reduced to counselling services. Adolescents were faced with various difficulties in their bid to access SRH services, including social stigma, attitude of service providers, fear of teachers and the anticipated negative response of parents due to the complex socio-cultural structure of Ghanaian society. Discussion with elders about SRH issues was considered a taboo.

Conclusion

Whilst social negotiation with parents, teachers and SRH service providers as well as school curricula alignment could arrest the barriers to adolescents’ access to SRH services, eHealth services such as the ‘Bisa’ Health App could potentially provide easy and cost-effective access to SRH information among in-school adolescents.

     

Health system strategies to increase HIV screening among pregnant women in Mesoamerica

Background

To propose health system strategies to meeting the World Health Organization (WHO) recommendations on HIV screening through antenatal care (ANC) services, we assessed predictors of HIV screening, and simulated the impact of changes in these predictors on the probability of HIV screening in Guatemala, Honduras, Mexico (State of Chiapas), Nicaragua, Panama, and El Salvador.

Methods

We interviewed a representative sample of women of reproductive age from the poorest Mesoamerican areas on ANC services, including HIV screening. We used a multivariate logistic regression model to examine correlates of HIV screening. First differences in expected probabilities of HIV screening were simulated for health system correlates that were associated with HIV screening.

Results

Overall, 40.7% of women were screened for HIV during their last pregnancy through ANC. This rate was highest in El Salvador and lowest in Guatemala. The probability of HIV screening increased with education, household expenditure, the number of ANC visits, and the type of health care attendant of ANC visits. If all women were to be attended by a nurse, or a physician, and were to receive at least four ANC visits, the probability of HIV screening would increase by 12.5% to reach 45.8%.

Conclusions

To meet WHO’s recommendations for HIV screening, special attention should be given to the poorest and least educated women to ensure health equity and progress toward an HIV-free generation. In parallel, health systems should be strengthened in terms of testing and human resources to ensure that every pregnant woman gets screened for HIV. A 12.5% increase in HIV screening would require a minimum of four ANC visits and an appropriate professional attendance of these visits.
