Reducing family and school-based violence at scale: a large-scale pre-post study of a parenting programme delivered to families with adolescent girls in Tanzania.

Background: Parenting programmes, including those delivered in the Global South, are effective strategies to reduce violence against children (VAC). However, there is limited evidence of their impact when implemented at scale within routine delivery systems. This study aimed to address this gap by evaluating the real-world delivery of Parenting for Lifelong Health for Teens in Tanzania.

Transactional sex and age-disparate sexual partnerships among adolescent girls and young women in Tanzania.

Introduction: Adolescent girls and young women (AGYW) continue to experience a high incidence of HIV in southern and eastern Africa, even in the context of large-scale HIV prevention interventions. In Tanzania, AGYW account for the largest proportion of new infections and have a higher risk of HIV acquisition than males of comparable age.

Methods: We used routinely collected data from the PEPFAR/USAID-funded Sauti Project, a large combination HIV prevention program, to examine the relationship between transactional sex and sex with older partners among AGYW in Tanzania (2015-2020).

A hybrid digital parenting programme to prevent abuse of adolescents in Tanzania: statistical analysis plan for a pragmatic cluster randomised controlled trial.

Background: Globally, violence against children poses substantial health and economic challenges, with estimated costs nearing USD 7 trillion. This prompts the urgent call for effective evidence-based interventions in preventing and mitigating violence against children. ParentApp is a mobile, open-source application designed to offer a remote version of the Parenting for Lifelong Health (PLH) programme.

A hybrid digital parenting programme to prevent abuse of adolescents in Tanzania: study protocol for a pragmatic cluster-randomised controlled trial.

Background: Evidence-based parenting programmes have strong evidence in preventing and mitigating violence, but in-person programmes are challenging to deliver at scale. ParentApp is an open-source, offline-first app-based adaptation of the Parenting for Lifelong Health for Parents and Teens programme to promote playful and positive parenting, reduce risks for sexual violence victimisation, and prevent violence against adolescents. This study aims to evaluate the effectiveness and cost-effectiveness of ParentApp compared to an attention-control group.

Pathways to transactional sex among peri-urban South African women: the role of relationship control, food insecurity and alcohol misuse.

Transactional sex increases sub-Saharan African women's risk of HIV acquisition. We quantitatively explored the pathways contributing towards women's future engagement in transactional sex with casual partners and khwapheni (secret concurrent sex partners). We conducted secondary data analysis from a cluster randomised controlled trial in urban informal settlements in eThekwini Municipality.

Systematic review of cash plus or bundled interventions targeting adolescents in Africa to reduce HIV risk.

Background: HIV remains a leading cause of death for adolescents and young people aged 10-24 years. HIV prevention requires multisectoral approaches that target adolescents and young people, addressing HIV risk pathways (e.g.

Partnerships with religious leaders to promote family planning in rural Tanzania: an open-label, cluster randomised trial.

Background: Family planning benefits maternal-child health, education, and economic wellbeing. Despite global efforts, an unsatisfied demand for family planning persists in sub-Saharan Africa. Based on previous successful partnerships, the aim of this study was to determine whether an educational intervention for religious leaders would increase community knowledge, demand for, and ultimately uptake of family planning.

Why marry early? Parental influence, agency and gendered conflict in Tanzanian marriages.

Global health interventions increasingly target the abolishment of 'child marriage' (marriage under 18 years, hereafter referred to as 'early marriage'). Guided by human behavioural ecology theory, and drawing on focus groups and in-depth interviews in an urbanising Tanzanian community where female early marriage is normative, we examine the common assumption that it is driven by the interests and coercive actions of parents and/or men. We find limited support for parent-offspring conflict.

Optimising engagement in a digital parenting intervention to prevent violence against adolescents in Tanzania: protocol for a cluster randomised factorial trial.

Background: Violence against adolescents is a universal reality, with severe individual and societal costs. There is a critical need for scalable and effective violence prevention strategies such as parenting programmes, particularly in low- and middle-income countries where rates of maltreatment are highest. Digital interventions may be a scalable and cost-effective alternative to in-person delivery, yet maximising caregiver engagement is a substantial challenge.

Shifting social norms to prevent age-disparate transactional sex in Tanzania: what we can learn from intervention development research.

This paper reflects on the development process (2015-2020) of the Learning Initiative for Norms, Exploitation, and Abuse (LINEA) Intervention. The LINEA Intervention is a multi-component social norms intervention to prevent age-disparate transactional sex in Tanzania. This paper aims to: (1) critically reflect on the LINEA Intervention development process by retrospectively comparing it with a pragmatic, phased framework for intervention development in public health, the Six Essential Steps for Quality Intervention Development (6SQuID); and (2) discuss the usefulness and applicability of this framework to guide intervention development for gender-based violence prevention.

A win-win scenario? Employers' responses to HIV in Tanzania: A qualitative study.

Workplaces have been increasingly promoted as key sites for HIV interventions, with cost-benefit analyses employed to demonstrate the financial benefits to employers for implementing workplace HIV programmes. In these analyses, the potential costs of having HIV positive employees are weighed against the costs of the workplace programmes. Despite evidence that shows some firms have saved significant sums of money through these interventions, the general response from the private sector has been limited, with most positive case studies originating from high prevalence settings.

Health providers' perspectives on contraceptive use in rural Northwest Tanzania: A qualitative study.

Objectives: In Tanzania, contraceptive use is limited, particularly in rural communities and even among women who would like to delay childbearing. This paper aims to present health providers' perspectives on populations seeking contraception and barriers that could be addressed to increase access to and uptake of contraception, given their interface with large portions of their communities.

Study Design: We conducted 18 in-depth interviews with providers stationed at health dispensaries in six rural villages in northwest Tanzania.

Sexual Harassment in Low- and Middle-Income Countries: A Qualitative Systematic Review.

Sexual harassment is a pervasive form of gender-based violence that has negative social and health impacts, yet there is only limited research available on sexual harassment in low- and middle-income countries (LMICs). The aim of this qualitative systematic review was to better understand how participants across a variety of countries and settings conceptualized sexual harassment and to investigate its causal factors, consequences, coping strategies, and recommendations for prevention and interventions. We searched eight databases and included English language qualitative studies published from 1990 until June 2021 if they mentioned sexual harassment in LMICs and included female or male participants aged 12 and older.

'It provides practical tips, practical solutions!': acceptability, usability, and satisfaction of a digital parenting intervention across African countries.

The parenting evidence base is well established, and the question is how best to transfer the evidence to an app. App-based interventions could expand access to evidence-based parenting support; however, current provision lacks rigorous evidence, shows low user engagement, and is primarily for commercial gain. This study aimed at testing the feasibility and acceptability of ParentApp for Teens, an open-source, mobile parenting intervention application based on the Parenting for Lifelong Health Teens programme targeting parents of teens.

A qualitative study exploring parent-daughter approaches for communicating about sex and transactional sex in Central Uganda: Implications for comprehensive sexuality education interventions.

Introduction: Ugandan adolescent girls and young women are disproportionately impacted by human immunodeficiency virus, and this is largely driven by their engagement in transactional sex. Globally, parent-daughter communication about sex is associated with increased contraceptive use and delayed/decreased sexual activity, but research on parent-daughter communication about transactional sex is lacking. This paper elucidates local perspectives on, and experiences of parent-daughter communication about sex and transactional sex, to inform family-level comprehensive sexuality education interventions.

"It Gives You a Feeling of Pride when You Touch Her": The Role of Masculinity in Sexual Harassment of Adolescent Schoolgirls in Tanzania.

Sexual harassment or the unwanted offensive behaviours that women and girls experience is a pervasive global challenge. Yet, there is limited evidence on the lived experiences of sexual harassment from school-based settings in sub-Saharan Africa. We explore students' perceived experiences, perpetration, and drivers of sexual harassment in schools in Mwanza, Tanzania.

Measuring transactional sex in different contexts: How do tools to measure this practice perform in rural South Africa?

Adolescent girls and young women across sub-Saharan Africa are at disproportionate risk of HIV infection compared to their male counterparts. Transactional sex has been identified as an important proximate risk for infection in this population. Definitions and measures of transactional sex vary, necessitating improved measures to better estimate prevalence across settings, over time, and to understand the mechanisms through which transactional sex increases HIV risk.

Safety monitoring experience of single-low dose primaquine co-administered with artemether-lumefantrine among providers and patients in routine healthcare practice: a qualitative study in Eastern Tanzania.

Background: Primaquine is a gametocytocidal drug recommended by the World Health Organization (WHO) in a single-low dose combined with artemisinin-based combination therapy (ACT) for the treatment and prevention of Plasmodium falciparum malaria transmission. Safety monitoring concerns and the lack of a universal validated and approved primaquine pharmacovigilance tool is a challenge for a national rollout in many countries. This study aimed to explore the acceptance, reliability and perceived effectiveness of the primaquine roll out monitoring pharmacovigilance tool (PROMPT).

HIV testing attitudes and practices amongst 'wealthy men': qualitative evidence from Tanzania.

Evidence from nationally representative surveys conducted in sub-Saharan Africa shows that significant proportions of men in the wealthiest quintile report never having tested for HIV. Despite high prevalence rates in this quintile, no research has been conducted on the HIV testing attitudes and practices of wealthier men. This article reports findings from qualitative research conducted with 23 wealthy men in Tanzania.

Male and Female Conceptualizations of Sexual Harassment in Tanzania: The Role of Consent, Male Power, and Social Norms.

Sexual harassment is pervasive worldwide, yet there is a lack of clarity on its conceptualization in many settings, especially in low-income countries. Context-specific conceptualization of sexual harassment is vital to develop effective measurement tools, estimate its magnitude, and the design of interventions to address it. We explored how different population groups in Mwanza, Tanzania, understood, conceptualized, and experienced sexual harassment.

Measurement and prevalence of sexual harassment in low- and middle-income countries: a systematic review and meta-analysis.

Objectives: We synthesise evidence on sexual harassment from studies in low-income and middle-income countries (LMICs) to estimate its prevalence and conduct a meta-analysis of the association between sexual harassment and depressive symptoms.

Methods: We searched eight databases. We included peer-reviewed studies published in English from 1990 until April 2020 if they measured sexual harassment prevalence in LMICs, included female or male participants aged 14 and over and conceptualised sexual harassment as an independent or dependant variable.

A mixed methods evaluation of the large-scale implementation of a school- and community-based parenting program to reduce violence against children in Tanzania: a study protocol.

Background: Despite the rapid dissemination of parenting programs aiming to reduce and prevent violence against children (VAC) worldwide, there is limited knowledge about and evidence of the implementation of these programs at scale. This study addresses this gap by assessing the quality of delivery and impact of an evidence-based parenting program for parents/caregivers and their adolescent girls aged 9 to 14-Parenting for Lifelong Health Teens (PLH-Teens), known locally as Furaha Teens-on reducing VAC at scale in Tanzania. The study will explore participating family and staff perspectives on program implementation and examine factors associated with implementation and how implementation quality is associated with intervention outcomes when the program is delivered to approximately 50,000 parent-child dyads (N = 100,000) in schools and community centers across eight districts of Tanzania.

Capitalising on aspirations of adolescent girls and young women to reduce their sexual health risks: Implications for HIV prevention.

This paper explores adolescent girls' and young women's (AGYW) aspirations, factors that influence aspirations, and how their aspirations inform their sexual decision-making and behaviour. This study employed a qualitative design involving six participatory focus group discussions and 17 in-depth interviews with AGYW in - and out-of-school. Fieldwork was undertaken in rural and urban Tanzania.

"I have never seen something like that": Discrepancies between lived experiences and the global health concept of child marriage in northern Tanzania.

Background: The concept of 'child marriage' in global health distinguishes ostensibly harmful from healthy ages to marry at a universally-applied threshold of 18-years. With intensifying efforts to end child marriage, targeted communities are increasingly asked to change their perception of such marriages from relatively benign to profoundly problematic. The objective of this study is to understand how this shift in perception is navigated by adolescent girls and young women (AGYW).
