Farmers’ perceptions of benefits and risks from wastewater irrigation in Accra, Ghana

As safe water sources become scarcer and more polluted, the use of wastewater in urban agriculture may produce many benefits but may also lead to crop and soil contamination and endanger farmers and consumers. To effectively manage wastewater use in agriculture, it is important to understand how stakeholders feel impacted by the practice.

Validity of measures for chronic disease in African settings

Epidemiological Change and Chronic Disease in Sub-Saharan Africa offers new and critical perspectives on the causes and consequences of recent epidemiological changes in sub-Saharan Africa, particularly on the increasing incidence of so-called ‘non-communicable’ and chronic conditions. Historians, social anthropologists, public health experts and social epidemiologists present important insights from a number of African perspectives and locations to present an incisive critique of ‘epidemiological transition’ theory and suggest alternative understandings of the epidemiological change on the continent. Arranged in three parts, ‘Temporalities: Beyond Transition’, ‘Numbers and Categories’ and ‘Local Biologies and Knowledge Systems’, the chapters cover a broad range of subjects and themes, including the trajectory of maternal mortality in East Africa, the African smoking epidemic, the history of sugar consumption in South Africa, causality between infectious and non-communicable diseases in Ghana and Belize, the complex relationships between adult hypertension and paediatric HIV in Botswana, and stories of cancer patients and their families as they pursue treatment and care in Kenya. In all, the volume provides insights drawn from historical perspectives and from the African social and clinical experience to offer new perspectives on the changing epidemiology of sub-Saharan Africa that go beyond theories of ‘transition’. It will be of value to students and researchers in Global Health, Medical Anthropology and Public Health, and to readers with an interest in African Studies

Global inequalities: the impact on health

This chapter discusses concepts of inequality and inequity in relation to health both within and between nations. It explores inequalities in health by characteristics, such as social class, gender, ethnicity, and the intersection of these. The chapter discusses the importance of the social gradient of health. It addresses competing explanations for health and social inequalities globally, including poverty and material deprivation, psychosocial factors, discrimination, and structural determinants of health. The ‘social gradient in health’ expresses the idea that health status is often patterned and that each successive increment in social position confers additional advantage. The way in which inequalities are measured, and the ethical priorities adopted for health interventions may impact our understanding, of whether inequalities are improving or worsening with time. Acknowledging social causation as an explanation for health inequalities, several possible mechanisms have been explored to explain how social conditions affect health

Explaining population trends in cardiovascular risk: protocol for a comparative analysis of health transitions in South Africa and England using nationally representative survey data

Introduction Cardiovascular diseases (CVD) are the leading cause of death globally and share determinants with other major non-communicable diseases. Risk factors for CVD are routinely measured in population surveys and thus provide an opportunity to study health transitions. Understanding the drivers of health transitions in countries that have not followed expected paths compared with those that exemplified models of ‘epidemiologic transition’, such as England, can generate knowledge on where resources may best be directed to reduce the burden of disease. This study aims to examine the notions of epidemiological transition by identifying and quantifying the drivers of change in CVD risk in a middle-income African setting compared with a high-income European setting. Methods and analysis This is a secondary joint analysis of data collected within the scope of multiple population surveys conducted in South Africa and England between 1998 and 2017 on nationally representative samples of the adult population. The study will use a validated, non-laboratory risk score to estimate and compare the distribution of and trends in total CVD risk in the population. Statistical modelling techniques (fixed-effects and random-effects multilevel regression models and structural equation models) will be used to examine how various factors explain the variation in CVD risk over time in the two countries. Ethics and dissemination This study has obtained approval from the University of Greenwich (20.5.6.8) and Stellenbosch University (X21/09/027) Research Ethics Committees. It uses anonymised microdata originating from population surveys which received ethical approval from the relevant bodies, with no additional primary data collection. Results of the study will be disseminated through (1) peer-reviewed articles in open access journals; (2) policy briefs; (3) conferences and meetings; and (4) public engagement activities designed to reach health professionals, governmental bodies, civil society and the lay public. A harmonised data set will be made publicly available through online repositories

Agricultural trade policies and child nutrition in low- and middle-income countries: a cross-national analysis

Background: There has been growing interest in understanding the role of agricultural trade policies in diet and nutrition. This cross-country study examines associations between government policies on agricultural trade prices and child nutrition outcomes, particularly undernutrition. Methods: This study links panel data on government distortions to agricultural incentives to data from 212,258 children aged 6 to 35 months participating in Demographic and Health Surveys from 22 countries between 1991 and 2010. Country fixed-effects regression models were used to examine the association between within-country changes in nominal rates of assistance to tradable agriculture (government price distortions as a percentage of original prices) and child nutritional outcomes (height-for-age, weight-for-age, and weight-for-height Z-scores) while controlling for a range of time-varying country covariates. Results: Five-year average nominal rates of assistance to tradable agriculture ranged from − 72.0 to 45.5% with a mean of − 5.0% and standard deviation of 18.9 percentage points. A 10-percentage point increase in five-year average rates of assistance to tradable agriculture was associated with improved height-for-age (0.02, 95% CI: 0.00–0.05) and weight-for-age (0.05, 95% CI: 0.02–0.09) Z-scores. Improvements in nutritional status were greatest among children who had at least one parent earning wages in agriculture, and effects decreased as a country’s proportion of tradable agriculture increased, particularly for weight-for-age Z-scores. Conclusions: Government assistance to tradable agriculture, such as through reduced taxation, was associated with small but significant improvements in child nutritional status, especially for children with a parent earning wages in agriculture when the share of tradable agriculture was not high

Improving stroke care in Ghana: a roundtable discussion with communities, healthcare providers, policymakers and civil society organisations

Even though there have been advances in medical research and technology for acute stroke care treatment and management globally, stroke mortality has remained high, with a higher burden in low- and middle-income countries (LMICs) such as Ghana. In Ghana, stroke mortality and disability rates are high, and research on post-stroke survival care is scarce. The available evidence suggests that Ghanaian stroke survivors and their caregivers seek treatment from pluralistic health care providers. However, no previous attempt has been made to bring them together to discuss issues around stroke care and rehabilitation. To address this challenge, researchers from the Institute of Advanced Studies, University College London, in collaboration with researchers from the African Centre of Excellence for Non-communicable diseases (ACE-NCDs), University of Ghana, organised a one-day roundtable to discuss issues around stroke care. The purpose of the roundtable was fourfold. First, to initiate discussion/collaborations among biomedical, ethnomedical and faith-based healthcare providers and stroke patients and their caregivers around stroke care. Second, to facilitate discussion on experiences with stroke care. Third, to understand the healthcare providers’, health systems’, and stroke survivors’ needs to enhance stroke care in Ghana. Finally, to define practical ways to improve stroke care in Ghana

Social capital is associated with improved subjective well-being of older adults with chronic non-communicable disease in six low- and middle-income countries

Background: Non-communicable diseases (NCDs) are increasingly contributing to the morbidity and mortality burden of low and-middle income countries (LMIC). Social capital, particularly participation has been considered as a possible protective factor in the prevention and management of chronic conditions. It is also largely shown to have a negative effect on the well-being of patients. The current discourse on the well-being of individuals with NCDs is however focused more on a comparison with those with no NCDs without considering the difference between individuals with one chronic condition versus those with multiple chronic conditions (MCC). Method and objective: We employed a multinomial logit model to examine the effect of social capital, particularly social participation, on the subjective well-being (SWB) of older adults with single chronic condition and MCC in six LMIC. Findings: Social capital was associated with increased subjective well-being of adults in all the six countries. The positive association between social capital and subjective well-being was higher for those with a single chronic condition than those with multiple chronic conditions in India and South Africa. Conversely, an increase in the likelihood of having higher subjective well-being as social capital increased was greater for those with multiple chronic conditions compared to those with a single chronic condition in Ghana. Discussion: The findings suggest that improving the social capital of older adults with chronic diseases could potentially improve their subjective well-being. This study, therefore, provides valuable insights into potential social determinants of subjective well-being of older adults with chronic diseases in six different countries undergoing transition. Additional research is needed to determine if these factors do in fact have causal effects on SWB in these populations

How chronic conditions are understood, experienced and managed within African communities in Europe, North America and Australia: a synthesis of qualitative studies

This review focuses on the lived experiences of chronic conditions among African communities in the Global North, focusing on established immigrant communities as well as recent immigrant, refugee, and asylum-seeking communities. We conducted a systematic and narrative synthesis of qualitative studies published from inception to 2022, following a search from nine databases—MEDLINE, EMBASE, PsycINFO, Web of Science, Social Science Citation Index, Academic Search Complete, CINAHL, SCOPUS and AMED. 39 articles reporting 32 qualitative studies were included in the synthesis. The studies were conducted in 10 countries (Australia, Canada, Denmark, France, Netherlands, Norway, Sweden, Switzerland, United Kingdom, and the United States) and focused on 748 participants from 27 African countries living with eight conditions: type 2 diabetes, hypertension, prostate cancer, sickle cell disease, chronic hepatitis, chronic pain, musculoskeletal orders and mental health conditions. The majority of participants believed chronic conditions to be lifelong, requiring complex interventions. Chronic illness impacted several domains of everyday life—physical, sexual, psycho-emotional, social, and economic. Participants managed their illness using biomedical management, traditional medical treatment and faith-based coping, in isolation or combination. In a number of studies, participants took ‘therapeutic journeys’–which involved navigating illness action at home and abroad, with the support of transnational therapy networks. Multi-level barriers to healthcare were reported across the majority of studies: these included individual (changing food habits), social (stigma) and structural (healthcare disparities). We outline methodological and interpretive limitations, such as limited engagement with multi-ethnic and intergenerational differences. However, the studies provide an important insights on a much-ignored area that intersects healthcare for African communities in the Global North and medical pluralism on the continent; they also raise important conceptual, methodological and policy challenges for national health programmes on healthcare disparities
