“…Fifth, burden assessments at the grid level may be biased due to the unavailability of subnational prevalence rates. Thus, burden assessments at the country level were the primary results in the present study, which was similar to a previous study . In addition, the cross-sectional study design could not provide the causality between dust PM 2.5 and anemia.…”

Addressing environmental factors has recently been recommended to curb the growing trend of anemia in low-and middle-income countries (LMICs). Fine particulate matter (PM 2.5 ) generated by dust storms were concentrated in place with a high prevalence of anemia. In a multicounty, multicenter study, we analyzed the association between anemia and life-course averaged exposure to dust PM 2.5 among children aged <5 years based on 0.65 million records from 47 LMICs. In the fully adjusted mixed effects model, each 10 μg/m 3 increase in life-course averaged exposure to dust PM 2.5 was associated with a 9.3% increase in the odds of anemia. The estimated exposure−response association was nonlinear, with a greater effect of dust PM 2.5 exposure seen at low concentrations. Applying this association, we found that, in 2017, among all children aged <5 years in the 125 LMICs, dust PM 2.5 contributed to 37.98 million cases of anemia. Results indicated that dust PM 2.5 contributed a heavier burden than all of the wellidentified risk factors did, except for iron deficiency. Our study revealed that long-term exposure to dust PM 2.5 can be a novel risk factor, pronouncedly contributed to the burden of child anemia in LMICs, affected by land degradations or arid climate.

Climate change severely threatens global public health, with sub-Saharan Africa (SSA) projected to experience profound impacts. This scoping review aimed to provide a comprehensive overview of current research on climate change and its health implications in SSA while identifying research gaps and outlining the necessary resources and policy interventions to strengthen public health resilience in the region. Literature was retrieved from four databases (PubMed, Scopus, Embase and Web of Science) using the keywords “climate change,” “health,” and “sub-Saharan Africa”. A total of 7851 journal articles were identified from the initial search, and after screening, 153 studies were included for review. The included studies were published between January 2001 and August 2024. Although extensive studies have been conducted on extreme heat (71 studies), drought (45 studies), extreme precipitation events (52 studies), and flooding (34 studies), important themes such as air quality (10 studies), chemical water quality (8 studies) and natural disasters (8) have been understudied. Additionally, this scoping review revealed a geographical gap in climate change and health studies, as only 24 out of 53 countries in sub-Saharan Africa were represented. The key deficiencies identified include limited funding, technological constraints, inadequate climate policies, and a lack of community-focused adaptation plans. Moreover, this review highlights the urgent need for resilient healthcare systems capable of addressing climate-related health risks effectively. Addressing these gaps is essential for developing targeted strategies to mitigate climate change's health impacts and increase resilience in SSA communities. This review aims to inform policymakers, researchers, and stakeholders about critical areas requiring attention and investment by enhancing our understanding of these challenges and gaps. Strengthening research capacities, fostering collaboration, and implementing evidence-based policies are imperative steps toward achieving sustainable health outcomes in the face of a changing climate in sub-Saharan Africa.
