Adolescent-led Our Voice method to promote healthy and active lifestyles and environments in South Africa
Adolescents’ immediate environments, including their homes, schools, and neighbourhoods, have a significant impact on their behaviour, health and development. Fostering adolescents’ agency and empowerment can drive environmental and behavioural changes that can lead to improved health outcomes and reduced disparities in current and future generations. The objective of the study was to pilot and evaluate the implementation of a “by the people” cit…
Activating urban infrastructure for health
Urban climate–NCD syndemics in LMICs
BACKGROUND: Climate change poses a major threat to global health. Its synergistic interaction with non-communicable diseases (NCDs), responsible for 74% of global deaths, demands urgent, integrated action. OBJECTIVES: This study critically examines how transdisciplinary approaches can uncover and address structural determinants underpinning climate change-NCD syndemic hazards, while accounting for power dynamics through meaningful stakeholder eng…
Community resilience to climate change and non-communicable disease vulnerability in Yaoundé, Cameroon
Background: Climate change and rapid urbanisation have intensified flood risk in Global South cities, exacerbating health inequities, especially through non-communicable diseases (NCDs). However, little is known about how community resilience strategies to key climate change consequences like flooding affect NCD risk in rapidly growing cities of the Global South. Methods: We used a Community-Based System Dynamics (CBSD) approach to examine flood …
Collective learning for resilience in Global South cities
Introduction: Cities in the Global South face escalating climate change challenges, including extreme weather events that disproportionately affect marginalized populations and exacerbate health risks, such as non-communicable diseases (NCDs). Climate resilience, defined as the capacity to adapt and recover from climate-related events, requires intersectoral collaboration between governments and civil society. Methods: This study employs a Commun…
Obesogenicity of food in the informal food retail environment of low- and middle-income countries
BACKGROUND: Evidence on food environment obesogenicity has largely focused on the formal sector in high-income countries, overlooking informal food retail environments in low- and middle-income countries (LMICs). AIM: To synthesise current evidence on the obesogenicity of foods in informal food retail environments in LMICs. METHODS: A systematic literature search across four academic databases: Scopus, Web of Science, EBSCOhost (Global Health) an…
Potential of citizen science to advance urban planetary health research in low and middle-income countries
Planetary health has emerged as a transdisciplinary field to capture the interdependencies between environmental changes and human health. Nowhere is this more critical than in the low- and middle-income country (LMIC) settings where the majority of the world’s population live. These settings are undergoing rapid urbanisation that could further threaten planetary boundaries. The collaborative and societally engaged nature of planetary health mean…
Urban public space initiatives and health in Africa
Public space initiatives (PSIs) in African cities can significantly promote health and social well-being, yet their implementation and impact are unknown across the continent. There is a substantial gap in literature on PSIs in African countries, with most studies concentrated in wealthier cities and lacking comprehensive assessments of long-term health impacts. The objective of this study was to synthesise evidence on the typology, location, fea…
Multisectoral interventions for urban health in Africa
Clustering of diet and physical activity behaviours in adolescents across home and school area-level deprivation in Cameroon, South Africa, and Jamaica
An inverse clustering of sedentary behaviour duration and eating habits remained consistent across different strata for at least two sites, suggesting that interventions to reduce sedentary time could have a ripple effect on multiple NCD risk factors in adolescence
Virtual Assessment of Physical Activity–Related Built Environment in Soweto, South Africa
Understanding how urban environments shape physical activity is critical in rapidly urbanizing countries such as South Africa. We assessed the reliability of virtual audits for characterizing urban features related to physical activity in Soweto, South Africa. We used the Microscale Audit of Pedestrian Streetscapes Global tool to characterize pedestrian-related features from Google Street View images in four neighborhoods of Soweto. Neighborhoods…
Association of Perceived Neighbourhood Walkability with Self-Reported Physical Activity and Body Mass Index in South African Adolescents
Adolescence is a life stage critical to the establishment of healthy behaviours, including physical activity (PA). Factors associated with the built environment have been shown to impact PA across the life course. We examined the sociodemographic differences in, and associations between, perceived neighbourhood walkability, PA, and body mass index (BMI) in South African adolescents. We recruited a convenience sample (n = 143; 13-18 years; 65% fem…
Participatory prioritisation of interventions to improve primary school food environments in Gauteng, South Africa
Prioritising evidence-based, feasible and important interventions underpinned by behaviour change theories is an important step towards enhanced policy making and resource allocation to tackle South Africa's childhood obesity epidemic effectively
Environmental correlates of adolescent active travel to school in Asia
This study shows that Asian countries with a greater number of people living in urban areas, lower levels of overall adult physical activity and higher levels of night-time light have a lower prevalence of adolescent AST. Country-level physical and social environmental correlates explained some of the regional variance in AST. Future policy actions and interventions for the region need to be contextually sensitive to the environmental correlates …
Comparing travel behaviour characteristics and correlates between large and small Kenyan cities (Nairobi versus Kisumu)
Understanding urban travel behaviour is crucial for planning healthy and sustainable cities. Africa is urbanising at one of the fastest rates in the world and urgently needs this knowledge. However, the data and literature on urban travel behaviour, their correlates, and their variation across African cities are limited. We aimed to describe and compare travel behaviour characteristics and correlates of two Kenyan cities (Nairobi and Kisumu). We …
The Lancet Nigeria Commission
Health is central to the development of any country. Nigeria’s gross domestic product is the largest in Africa, but its per capita income of about ₦770 000 (US$2000) is low with a highly inequitable distribution of income, wealth, and therefore, health. It is a picture of poverty amidst plenty. Nigeria is both a wealthy country and a very poor one. About 40% of Nigerians live in poverty, in social conditions that create ill health, and with the e…
Open science communication
The COVID-19 pandemic has shone a light on the complex relationship between science and policy. Policymakers have had to make decisions at speed in conditions of uncertainty, implementing policies that have had profound consequences for people's lives. Yet this process has sometimes been characterised by fragmentation, opacity and a disconnect between evidence and policy. In the United Kingdom, concerns about the secrecy that initially surrounded…
Mapping food and physical activity environments in low- and middle-income countries
This systematised literature review synthesised evidence on approaches to mapping food and physical activity (PA) environments in low- and middle-income countries (LMICs). Of the 60 articles included, 25 and 35 mapped food and PA environments respectively. All studies were cross-sectional with researcher-led data collection. Three types of mapping tools were identified - maps (n = 18), GPS (n = 10), and GIS (n = 37). Our findings point to a pauci…
Health trends, inequalities and opportunities in South Africa’s provinces, 1990–2019
BACKGROUND: Over the last 30 years, South Africa has experienced four 'colliding epidemics' of HIV and tuberculosis, chronic illness and mental health, injury and violence, and maternal, neonatal, and child mortality, which have had substantial effects on health and well-being. Using data from the 2019 Global Burden of Diseases, Injuries and Risk Factors Study (GBD 2019), we evaluated national and provincial health trends and progress towards imp…
Analysis of Cameroon’s Sectoral Policies on Physical Activity for Noncommunicable Disease Prevention
Physical inactivity is increasing in low- and middle-income countries (LMICs), where noncommunicable diseases (NCDs), urbanisation and sedentary living are rapidly growing in tandem. Increasing active living requires the participation of multiple sectors, yet it is unclear whether physical activity (PA)-relevant sectors in LMICs are prioritising PA. We investigated to what extent sectors that influence PA explicitly integrate it in their policies…
Intersectoral Action for Addressing NCDs through the Food Environment
Noncommunicable diseases contribute the greatest to global mortality. Unhealthy diet-a prominent risk factor-is intricately linked to urban built and food environments and requires intersectoral efforts to address. Framings of the noncommunicable disease problem and proposed solutions within global and African regional diet-related policy documents can reveal how amenable the policy landscape is for supporting intersectoral action for health in l…
The global diet and activity research (GDAR) network
Implications of Covid-19 control measures for diet and physical activity, and lessons for addressing other pandemics facing rapidly urbanising countries
At the time of writing, it is unclear how the COVID-19 pandemic will play out in rapidly urbanising regions of the world. In these regions, the realities of large overcrowded informal settlements, a high burden of infectious and non-communicable diseases, as well as malnutrition and precarity of livelihoods, have raised added concerns about the potential impact of the COVID-19 pandemic in these contexts. COVID-19 infection control measures have b…
Missed opportunities for NCD multimorbidity prevention in adolescents and youth living with HIV in urban South Africa
Our study demonstrates limited NCD screening and health promotion in AYLHIV accessing healthcare services. Where documented, our data demonstrates existing NCD comorbidity and NCD risk factors highlighting a missed opportunity for multimorbidity prevention through NCD screening and health promotion. Addressing this missed opportunity requires an integrated health system and intersectoral action on upstream NCD determinants to turn the tide on the…
Slum Health
The informal settlements of the Global South are the least prepared for the pandemic of COVID-19 since basic needs such as water, toilets, sewers, drainage, waste collection, and secure and adequate housing are already in short supply or non-existent. Further, space constraints, violence, and overcrowding in slums make physical distancing and self-quarantine impractical, and the rapid spread of an infection highly likely. Residents of informal se…

A cross-sectional and spatial analysis of the prevalence of multimorbidity and its association with socioeconomic disadvantage in South Africa
This study utilised data from the National Income Dynamics Study, a longitudinal study with a sample of approximately 28 000 people, to investigate the cross-sectional and spatial distribution of multimorbidity and the association with socioeconomic disadvantage in South Africa for 2008 and 2012. Multimorbidity increased in prevalence from 2.73% to 2.84% in adults between 2008 and 2012 and was associated with age, socioeconomic deprivation, obesi…
Health through human settlements
Informal settlements, characterised by inadequate living conditions and high disease burdens, continue to grow in response to rapid urban development in the Global South, and international health agendas call for intersectoral action to address the social determinants of health. However, little is known in these contexts about policymakers’ knowledge of social determinants of health. Exploring policymaker perceptions can provide insight into poss…

Chronic diseases and multi-morbidity - a conceptual modification to the WHO ICCC model for countries in health transition
Our proposed modification to the ICCC Framework makes clear that healthcare systems must work to make sense of the complex collision between biological phenomena, clinical interpretation, beliefs and behaviours that follow from these. We emphasize the integration of these issues with the socio-economic environment to address issues of complexity, access and equity in the integrated management of chronic diseases previously considered in isolation
Prevalence of Menstrual Disorders and its Academic Impact amongst Tshivenda Speaking Teenagers in Rural South Africa
This paper investigated the prevalence of menstrual disorders and its impact amongst Tshivenda speaking teenagers in rural South Africa. The paper adopted a quantitative approach using a descriptive survey design. Data were collected from a total of 173 randomly selected females, age 14-18 years from 10 secondary schools that makes up a rural Vhumbedzi circuit in the Limpopo province using a self-administered questionnaire. Validity and reliabili…
The Pan-University Network for Global Health
In the current United Nations efforts to plan for post 2015-Millennium Development Goals, global partnership to address non-communicable diseases (NCDs) has become a critical goal to effectively respond to the complex global challenges of which inequity in health remains a persistent challenge. Building capacity in terms of well-equipped local researchers and service providers is a key to bridging the inequity in global health. Launched by Penn S…
Urban Health Research in Africa
In Africa, urbanization and urban growth are dramatically restructuring the nature of cities. The growing majority of urban dwellers now live in informal conditions that, without access to basic services or public amenities, expose residents to greater health risk, and health-care systems are unable to provide affordable or comprehensive cover. The differential exposure to these urban conditions is compounded by social and economic vulnerability,…

Urban health in Africa
The African continent is predicted to be home to over half of the expected global population growth between 2015 and 2050, highlighting the importance of addressing population health in Africa for improving public health globally. By 2050, nearly 60% of the population of the continent is expected to be living in urban areas and 35-40% of children and adolescents globally are projected to be living in Africa. Urgent attention is therefore required…
