This study explored the approaches used during adolescent VMMC counseling and whether these strategies maximize broader HIV prevention opportunities. Methods Qualitative interviews...

Early infant male circumcision (EIMC) is a potential key HIV prevention intervention, providing it can be safely and efficiently implemented in sub-Saharan Africa. Here we present results of a randomized noninferiority trial of EIMC comparing the AccuCirc device with Mogen clamp in Zimbabwe. Between January-June 2013, eligible infants were randomiz...

Infant male circumcision (IMC) may be more effective at preventing HIV than adult male circumcision as the procedure is carried out before the individual becomes sexually active. Successful scale-up will depend on identifying and overcoming parental concerns that may act as barriers for IMC. We conducted a systematic review to identify qualitative...

Male engagement in maternal, newborn and child health (MNCH) is a promising strategy to improve MNCH outcomes and gender equity. There has been an upswell of interest in male engagement in MNCH, and it is currently being promoted and adopted at the global, national and subnational level through policy and program planning. Yet the direct links betw...

A working alliance (WA) is a multidimensional construct signifying a collaborative relationship between a client and a therapist. Systematic reviews of therapies to treat depression and anxiety, almost exclusively in adults, show WA is essential across psychotherapies. However, there are critical gaps in our understanding of the importance of WA in...

Background Voluntary medical male circumcision (VMMC) has been a recommended HIV prevention strategy in sub-Saharan Africa since 2007, particularly in countries with high HIV prevalence. However, given the scale-up of antiretroviral therapy programmes, it is not clear whether VMMC still represents a cost-effective use of scarce HIV programme resour...

Introduction Sub-Saharan Africa bears the greatest burden of HIV. Concomitant mental disorders are common, necessitating the integration of mental healthcare into routine HIV care. Consequently, it is necessary to holistically evaluate the mental health of adolescents and young adults living with HIV (AYALHIV, 10–24 years old) by measuring negative...

Anatomical, physiological and socio‐cultural changes during pregnancy and childbirth increase vulnerability of women and newborns to high ambient temperatures. Extreme heat can overwhelm thermoregulatory mechanisms in pregnant women, especially during labour, cause dehydration and endocrine dysfunction, and compromise placental function. Clinical s...

Background HIV-related stigma, including self-stigma, is a significant barrier to managing HIV. Self-stigma can have severe consequences for mental health and well-being. However, the impacts of HIV-related self-stigma are poorly understood. This study explored the beliefs, experiences and impacts of HIV self-stigma amongst adolescents and young a...

Objectives HIV testing is the gateway to HIV prevention and care services. Female sex workers (FSW) may benefit from HIV self-testing (HIVST), which offers greater control and confidentiality than other approaches. However, FSW also have unique vulnerabilities, making it critical to understand their perspective of HIVST to best contextualise HIVST...

Introduction Reaching men aged 20–35 years, the group at greatest risk of HIV, with voluntary medical male circumcision (VMMC) remains a challenge. We assessed the impact of two VMMC demand creation approaches targeting this age group in a randomised controlled trial (RCT). Methods We conducted a 2×2 factorial RCT comparing arms with and without t...

Despite a recent decline, Zimbabwe still has the fifth highest adult HIV prevalence in the world at 14.7%; 56% of the population are currently living in extreme poverty. Cross-sectional population-based survey of 18-22 year olds, conducted in 30 communities in south-eastern Zimbabwe in 2007. To examine whether the risk of HIV infection among young...

The overall aim of the research outlined in this PhD thesis is to assess the feasibility and acceptability of early infant male circumcision (EIMC) as an HIV prevention intervention in Zimbabwe in order to inform roll out. Mathematical modelling estimates that circumcising 1.9 million Zimbabwean men aged 15-49 by 2015 could avert 42% of new HIV inf...

The global commitment to universal access for people in need of antiretroviral therapy has transformed the lives of adolescents with HIV. In contrast, there has been limited commitment at policy or service level to the need for effective therapeutic interventions which help them to cope with their life experiences. It is imperative that the scale u...

Background and methods: By December 2013, it was estimated that close to 6 million men had been circumcised in the 14 priority countries for scaling up voluntary medical male circumcision (VMMC), the majority being adolescents (10-19 years). This article discusses why efforts to scale up VMMC should prioritize adolescent men, drawing from new evid...

We conducted quantitative and qualitative studies to explore barriers and motivating factors to VMMC for HIV prevention, and to assess utilization of existing VMMC communication channels.
