This report describes the methods and main findings examining the intersection between non-communicable diseases (NCDs) and COVID-19 deaths in low and middle income countries (LMICs). This report presents the results of a literature review and a statistical regression exploring the relationship between NCDs and COVID-19 deaths. The statisti- cal regression reveals a range of socioeconomic, health and environmental factors which influence the relationship between NCDs and COVID-19 deaths. Using these factors com- bined with findings from the literature and expert engagement, we propose key strategies for mitigating COVID-19 that are sensitive to NCD burden in LMICs. To note, the findings and views expressed in this report are those of The Defeat-NCD Partnership and the The Economist Intelligence Unit. In addition to the financial and human resources allocated by The Defeat-NCD Partnership for the development of this report, The Economist Intelligence Unit has received support from Viatris through a financial contribution towards the preparation of this report.

Simul- taneously, COVID-19 is exacerbating social inequities, which will lead to a greater NCD burden in LMICs and worldwide if action is not taken immediately.6
