Healthy Food Prices Increased More Than the Prices of Unhealthy Options during the Covid-19 Pandemic and Concurrent Challenges to the Food System
Food prices have escalated due to impacts of the COVID-19 pandemic on global food systems, and other regional shocks and stressors including climate change and war. Few studies have applied a health lens to identify the most affected foods. This study aimed to assess costs and affordability of habitual (unhealthy) diets and recommended (healthy, equitable and more sustainable) diets and their components in Greater Brisbane, Queensland, Australia …
Exploring Perceived Barriers and Facilitators of PrEP Uptake among Young People in Uganda, Zimbabwe, and South Africa
Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy. Few studies have explored adolescents and young people’s perspectives toward PrEP. We conducted 24 group discussions and 60 in-depth interviews with males and females aged 13–24 years in Uganda, Zimbabwe, and South Africa between September 2018 and February 2019. We used the framework approach to generate themes and key concepts for analysis following the social ecological m…
Behavioural Determinants of Hand Washing and Glove Recontamination before Aseptic Procedures at Birth
Recent research calls for distinguishing whether the failure to comply with World Health Organisation hand hygiene guidelines is driven by omitting to rub/wash hands, or subsequently recontamination of clean hands or gloves prior to a procedure. This study examined the determinants of these two behaviours. Across the 10 highest-volume labour wards in Zanzibar, we observed 103 birth attendants across 779 hand hygiene opportunities before aseptic p…
HIV serostatus, inflammatory biomarkers and the frailty phenotype among older people in rural KwaZulu-Natal, South Africa
Objective : We compared the prevalence of frailty by HIV serostatus and related biomarkers to the modified frailty phenotype among older individuals in a rural population in South Africa. Methods : Questionnaire data were from a cohort of people living with HIV (PWH) on antiretroviral therapy (ART) and HIV-uninfected people aged 50 years and older sampled from the Africa Health Research Institute Demographic Health and Surveillance area in northe…
Comparison of HIV Risk Behaviors Between Clinical Trials and Observational Cohorts in Uganda
Many key populations have high-risk behaviors for HIV infection making them suitable for HIV vaccine efficacy trials. However, these behaviors may change when participants enroll into a trial. We used HIV simulated vaccine efficacy trials (SiVETs) nested within observational cohorts of fisherfolks and female sex workers in Uganda to evaluate this difference. We screened observational cohort participants for enrolment into SiVETs, until 572 were e…
Averting Lemur Extinctions amid Madagascar's Political Crisis
Community-based management, ecotourism, and researchers' presence are proposed to prevent lemur extinctions.
