‘ … They Just Take One Pill, So It Is Easy to Use, More Convenient … ’
The Dual Prevention Pill (DPP) is a daily oral pill containing oral pre-exposure prophylaxis (PrEP) for protection against HIV and a combined oral contraceptive (COC) for the prevention of unintended pregnancy, currently under development. However, little is known about healthcare providers' (HCPs) perspectives on this potential new multipurpose prevention technology (MPT). A more granular understanding of HCP views about the DPP may support effo…
“…This could be a noble idea and a game changer.” The potential of a dual prevention pill for HIV and pregnancy prevention among adolescent girls and young women in Zimbabwe
Adolescent girls and young women (AGYW) in Zimbabwe bear a double burden of HIV and unmet need despite the progress made in provision of family planning and oral pre-exposure prophylaxis (PrEP). We elicited opinions from AGYW and health care providers (HCPs) about a dual prevention pill (DPP) in development that combines oral contraceptives (OCs) with oral PrEP to simultaneously prevent unintended pregnancy and HIV, and potentially increase uptak…
“Let’s chat!” Piloting a digital chatbot for HIV prevention among cisgender women and transgender men in Nigeria
Awareness and uptake of HIV pre-exposure prophylaxis (PrEP), a highly efficacious medication for HIV prevention, remains low in many sub-Saharan African countries. This study explored the acceptability and feasibility of an HIV prevention chatbot tailored for cisgender women and transgender men in Lagos, Nigeria. The chatbot was developed and implemented in the Nigerian healthcare context using participatory approaches engaging HIV healthcare pro…
A Dual Prevention Pill for HIV & Pregnancy Prevention
Adolescent girls and young women (AGYW) in sub-Saharan Africa are at risk for HIV/unintended pregnancy. Adherence and continuation to effective oral pre-exposure prophylaxis (PrEP) are limited in AGYW. We hypothesized that an over-encapsulated dual prevention pill (DPP) combining PrEP + oral contraceptive (OC) would be preferred, acceptable, and improve adherence compared to PrEP alone. We randomized HIV-uninfected, 16-24 year-olds 1:1 to use DPP…
The impact of high intensity training and sports on recipients of solid organ transplants
Examining concordance of sexual-related factors and PrEP eligibility with HIV risk perception among adolescent girls and young women
AGYW's HIV risk perceptions were mostly influenced by factors beyond their locus of control. Conditional PrEP eligibility criteria may inhibit AGYW's access and uptake in some settings: countries should consider decoupling these factors to minimize barriers. Intersections between autonomy, behaviors, and perceptions among AGYW in gender-inequitable settings warrants further investigation
Men's Willingness to Use and Preferences for Novel Male Contraceptive Methods in Malawi
Evidence is needed in low‐ and middle‐income countries regarding men's willingness to use new male contraceptive methods in development, preferences regarding method attributes, and what shapes willingness/preferences. We analyzed data from cross‐sectional surveys with 611 men in Malawi, concerning willingness to use each of four types of new male methods. Mean age was 24.5 years; half (50 percent) were married/cohabiting. Over half (51 percent) …
Thermal Adaptations in Indian Houses
This study investigates how the residents in Tiruchirapalli, India adapt to extreme summer temperatures within residential buildings, focusing on the hottest hours of the day. The research aims to understand adaptive behaviors to reduce dependence on mechanical heating and cooling systems, emphasizing the importance of innovative building designs
Social support and very young adolescent girl’s knowledge on sexual relationships
Early sexual relationships are associated with an increased risk of acquiring sexually transmitted diseases including HIV/AIDs, teenage pregnancies, and unsafe abortions among other negative health outcomes. Understanding sexual relationships among very young adolescents (VYAs) is important to equip them to protect themselves from negative sexual health (SH) outcomes. DREAMS ( D etermined, R esilient, E mpowered, A IDS-free, M entored, and S afe)…
Hearing From Men Living With HIV
Engaging men in HIV services remains a challenge across sub-Saharan Africa. There is a critical need to better understand facilitators of men's successful engagement with HIV services and assess if there are similarities across contexts. We conducted in-depth interviews and focus group discussions with 92 men living with HIV (MLHIV) across Malawi, Uganda, South Africa, and Eswatini, most of whom had been diagnosed with HIV within the last 5 years…
“When you live in good health with your husband, then your children are in good health ….” A qualitative exploration of how households make healthcare decisions in Maradi and Zinder Regions, Niger
Women are involved to varying degrees in health decision-making. Program activities that focus on improving communication among spouses should be sustained to enhance women role in health decision-making. Male engagement strategies that emphasize spousal communication, provide health information, discuss household labor may enhance couple communication in Niger. Adapting the outreach strategies and messages by healthcare topic, such as couples co…
Oral PrEP Consultations Among Adolescent Girls and Young Women in Kisumu County, Kenya
Although Kenya nationally scaled up oral pre-exposure prophylaxis (PrEP) in May 2017, adolescent girls' (AG, aged 15-19 years) and young women's (YW, aged 20-24 years) PrEP use remains suboptimal. Thus, we analyzed PrEP consultations-interactions with a healthcare provider about PrEP-among Kenyan AGYW. In April-June 2018, AGYW enrolled in DREAMS in Kisumu County, Kenya self-reported their HIV-related knowledge, behaviors, and service use. Among H…
A man without money getting a sexual partner? It doesn’t exist in our community”
Research on transactional sexual relationships has largely focused on women's perspectives. Better understanding the men's views-especially regarding relationships with adolescent girls and young women-can inform HIV prevention efforts. In 2017, 134 in-depth interviews were conducted with the male partners of girls and young women aged 19-47 years, 94 in Uganda and 40 in Eswatini. Respondents were recruited at venues such as bars where men and po…
Intersections of financial agency, gender dynamics, and HIV risk
Objectives : Recent research demonstrates that economic interventions may positively effect HIV risk among adolescent girls and young women (AGYW) in sub-Saharan Africa. Some evidence reveals potential associations between financial decision-making and bargaining power in sexual relationships. However, this evidence is mixed, nuanced, and limited. This paper explores how AGYW in Zambia understand financial agency and its effect on intimate relati…
Girl-only clubs’ influence on SRH knowledge, HIV risk reduction, and negative SRH outcomes among very young adolescent girls in rural Malawi
Girls-only HIV and SRH programs coupled with economic empowerment for their families can be effective in keeping VYA girls in school and improving SRH knowledge and health seeking behavior
Couple perspectives on unintended pregnancy in an area with high HIV prevalence
Understanding how couples perceive a recent unintended pregnancy in the context of HIV infection and high levels of gender inequality may provide insights for prevention of undesired pregnancy. We used data from 24 in-depth interviews with 8 HIV-serodiscordant and 4 seroconcordant couples living in rural Uganda and interviewed separately; between 15 and 49 years and one or both identified the pregnancy as unintended. A dyadic analysis was perform…
Contraceptive knowledge, perceptions, and concerns among men in Uganda
Overall, we found limited accurate knowledge about contraceptive methods among men in Uganda. Moreover, fears about the side effects of modern contraceptive methods appeared to be common among men. Family planning services in Uganda could be significantly strengthened by renewed efforts to focus on men's knowledge, fears, and misconceptions
Fatherhood, marriage and HIV risk among young men in rural Uganda
Compared to a large body of work on how gender may affect young women's vulnerability to HIV, we know little about how masculine ideals and practices relating to marriage and fertility desires shape young men's HIV risk. Using life-history interview data with 30 HIV-positive and HIV-negative young men aged 15-24 years, this analysis offers an in-depth perspective on young men's transition through adolescence, the desire for fatherhood and experie…
Mobility among youth in Rakai, Uganda
Mobility, including migration and travel, influences risk of HIV. This study examined time trends and characteristics among mobile youth (15-24 years) in rural Uganda, and the relationship between mobility and risk factors for HIV. We used data from an annual household census and population-based cohort study in the Rakai district, Uganda. Data on in-migration and out-migration were collected among youth (15-24 years) from 43 communities from 199…
Public discourse on HIV and Aids
reporting by Kirby (1986-1995). We examined the continuing evolution in the public discourse in Uganda, focusing on reporting about young people. An increase in reporting on HIV and AIDS occurred after 2003, as antiretroviral treatment was becoming available. While the emphasis in newspaper reporting about adults and the population at large evolved to reflect the development of new HIV treatment and prevention methods, the majority of the article…
Importance of Relationship Context in HIV Transmission
We present results from life history interviews with 60 young adults from southern Uganda. Using a novel qualitative case-control design, we compared newly HIV-positive cases with HIV-negative controls matched on age, gender, marital status, and place of residence. Relationship context was the most salient theme differentiating cases from controls. Compared with HIV-negative respondents, recent seroconverters described relationships marked by poo…
Modelling migration of contaminants from waste disposal facility
Waste disposal facility design must involve some form of barrier that separates the waste from the groundwater system located below it. This barrier is intended to minimize the migration of contaminants from the waste facility. Natural clay deposits and compacted clay liners of a certain minimum thickness are often used to prevent leachate from flowing down towards groundwater. The finite difference numerical model developed in this study is vali…
Adolescent girls' life aspirations and reproductive health in Nepal
The study described in this paper takes a participatory and positive approach to improving adolescent reproductive health in a rural and urban community in Nepal. It shows that adolescent girls in these communities have dreams and aspirations for a better future and that adults acknowledge and support these ideals. However, social norms and institutions are restrictive, especially for girls, who are often unable to realise their hopes for continu…
