The local dynamics of sociostructural features and HIV stigma in the HPTN 071 (PopART) trial
Across sub-Saharan Africa, stigma levels have been decreasing but not enough to achieve the 95–95–95 HIV targets by 2030. Current global HIV frameworks have identified stigma reduction, context specific interventions, and community mobilization as critical to enabling more effective uptake of HIV services. We conducted a retrospective analysis of longitudinal qualitative and quantitative data collected in 21 urban communities in Zambia and South …
Does a school-based intervention increase girls’ sexual and reproductive health attitudes and intentions? Results from a mixed-methods cluster-randomized trial in Burkina Faso
Adolescent girls in Burkina Faso face unintended pregnancy risk due to a lack of contraceptive use. The (re)solve project was designed to address contraceptive misperceptions and increase girls’ perceptions of their pregnancy risk, primarily through a participatory game and a health passport aimed at easing health facility access. The intervention components were implemented for girls in private and public school in grades 4ème and 3ème (grades 9…
Understanding the treatment burden of people with chronic conditions in Kenya
In Kenya, non-communicable diseases (NCDs) are an increasingly important cause of morbidity and mortality, requiring both better access to health care services and self-care support. Evidence suggests that treatment burdens can negatively affect adherence to treatment and quality of life. In this study, we explored the treatment and self-management burden among people with NCDs in in two counties in Western Kenya. We conducted a cross-sectional s…
The effect of universal testing and treatment for HIV on health-related quality of life – An analysis of data from the HPTN 071 (PopART) cluster randomised trial
The intervention did not change overall HRQoL, suggesting that raising HRQoL among PLHIV might require more than improved testing and treatment. However, PLHIV had fewer problems with pain/discomfort under the full intervention; this benefit of UTT should be maximised during roll-out
Community-based health workers implementing universal access to HIV testing and treatment
The global expansion of HIV testing, prevention and treatment services is necessary to achieve HIV epidemic control and promote individual and population health benefits for people living with HIV (PLHIV) in sub-Saharan Africa. Community-based health workers (CHWs) could play a key role in supporting implementation at scale. In the HPTN 071 (PopART) trial in Zambia and South Africa, a cadre of 737 study-specific CHWs, working closely with governm…
Universal HIV testing and treatment and HIV stigma reduction
Despite continued development of effective HIV treatment, expanded access to care and advances in prevention modalities, HIV-related stigma persists. We examine how, in the context of a universal HIV-testing and treatment trial in South Africa and Zambia, increased availability of HIV services influenced conceptualisations of HIV. Using qualitative data, we explore people's stigma-related experiences of living in 'intervention' and 'control' stud…
Reducing HIV- and TB-Stigma among healthcare co-workers in South Africa
Being seen” at the clinic
Health workers in 21 government health facilities in Zambia and South Africa linked spatial organisation of HIV services and material items signifying HIV-status (for example, coloured client cards) to the risk of People Living with HIV (PLHIV) 'being seen' or identified by others. Demarcated HIV services, distinctive client flow and associated-items were considered especially distinguishing. Strategies to circumvent any resulting stigma mostly i…
Investigating associations between the built environment and physical activity among older people in 20 UK towns
BACKGROUND: Policy initiatives such as WHO Age Friendly Cities recognise the importance of the urban environment for improving health of older people, who have both low physical activity (PA) levels and greater dependence on local neighbourhoods. Previous research in this age group is limited and rarely uses objective measures of either PA or the environment. METHODS: We investigated the association between objectively measured PA (Actigraph GT3x…

The intervention effect of local alcohol licensing policies on hospital admission and crime
BACKGROUND: Control of alcohol licensing at local government level is a key component of alcohol policy in England. There is, however, only weak evidence of any public health improvement. We used a novel natural experiment design to estimate the impact of new local alcohol licensing policies on hospital admissions and crime. METHODS: We used Home Office licensing data (2007-2012) to identify (1) interventions: local areas where both a cumulative …
Optimising measurement of health-related characteristics of the built environment
The role of the neighbourhood environment in influencing health behaviours continues to be an important topic in public health research and policy. Foot-based street audits, virtual street audits and secondary data sources are widespread data collection methods used to objectively measure the built environment in environment-health association studies. We compared these three methods using data collected in a nationally representative epidemiolog…
A qualitative geographical information systems approach to explore how older people over 70 years interact with and define their neighbourhood environment
A growing body of literature explores the relationship between the built environment and health, and the methodological challenges of understanding these complex interactions across the lifecourse. The impact of the neighbourhood environment on health and behaviour amongst older adults has received less attention, despite this age group being potentially more vulnerable to barriers in their surrounding social and physical environment. A qualitati…
Contribution of the physical environment to socioeconomic gradients in walking in the Whitehall II study
Socioeconomic gradients in walking are well documented but the underlying reasons remain unclear. We examined the contribution of objective measures of the physical environment at residence to socioeconomic gradients in walking in 3363 participants (50-74years) from the Whitehall II study (2002-2004). Individual-level socioeconomic position was measured as most recent employment grade. The contribution of multiple measures of the physical environ…
Association of leg length with overweight and obesity in children aged 5–15 years
Background: Short leg length (LL) and childhood obesity have been independently associated with a higher risk for adult disease. However, the contribution of relative LL to overweight and obesity in children remains an under-researched area.Aim: To utilize data from a large cross-sectional anthropometric survey to assess the association of LL to height ratio (LLHR, leg length/height) with measures of overweight and obesity in British children.Met…
