An analysis looks at whether strategies to reduce the global burden of noncommunicable disease could aid pandemic preparedness

A line chart titled “Health Risks in LMICs” shows how the leading risk factors for disease burden change in low- and middle-income countries (LMICs) from 1990 to 2023. In 1990, malnutrition ranks highest, followed by unsafe water, sanitation and hygiene (WASH), household air pollution, high blood pressure, dietary risks, tobacco, and high body-mass index. Over time, noncommunicable disease risks rise. By 2023, high blood pressure and dietary risks are the top contributors, while malnutrition and household air pollution decline in rank. Tobacco and high body-mass index increase modestly, and unsafe WASH drops to the lowest rank. The chart highlights a shift from communicable and environmental risks toward chronic disease risks in LMICs.
