The relationship between climate change, globalization and non-communicable diseases in Africa: A systematic review

Abstract

Climate change and non-communicable diseases (NCDs) are considered the 21st Century’s major health and development challenges. Both pose a disproportionate burden on low- and middle-income countries that are unprepared to cope with their synergistic effects. These two challenges pose risks for achieving many of the sustainable development goals (SDGs) and are both impacted by globalization through different pathways. While there are important insights on how climate change and or globalization impact NCDs in the general literature, comprehensive research that explores the influence of climate change and or globalization on NCDs is limited, particularly in the context of Africa. This review documents the pathways through which climate change and or globalization influence NCDs in Africa. We conducted a comprehensive literature search in eight electronic databases—Web of Science, PubMed, Scopus, Global Health Library, Science Direct, Medline, ProQuest, and Google Scholar. A total of 13864 studies were identified. Studies that were identified from more than one of the databases were automatically removed as duplicates (n = 9649). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a total of 27 studies were eventually included in the final review. We found that the impacts of climate change and or globalization on NCDs act through three potential pathways: reduction in food production and nutrition, urbanization and transformation of food systems. Our review contributes to the existing literature by providing insights into the impact of climate change and or globalization on human health. We believe that our findings will help enlighten policy makers working on these pathways to facilitate the development of effective policy and public health interventions to mitigate the effects of climate change and globalization on the rising burden of NCDs and goal 3 of the SDG, in particular.

Co-creating cancer control strategies in a strained healthcare landscape

“…Siiba et al. 11 in a systematic review found that extremes of weather from drought to flooding disrupt healthcare for people living with cancer, diabetes, and cardiovascular disease. These patients were at risk of exacerbation of health problems following such disasters because of interruptions with their treatment, problems with drug supplies chains, or inability to access healthcare due transport disruptions.…”

“…These patients were at risk of exacerbation of health problems following such disasters because of interruptions with their treatment, problems with drug supplies chains, or inability to access healthcare due transport disruptions. 11 Mitigating the devastating impact of climate change on human development is way beyond the health system yet the resultant disease, suffering and deaths are a medical problem.…”
