A comprehensive study in The Lancet reveals the global health impacts of 88 risk factors, emphasizing the significant burden of air pollution and high blood pressure.
By Dr. Priyom Bose, Ph.D.May 21 2024Reviewed by Benedette Cuffari, M.Sc. A recent study published in The Lancet estimates relative health risks, exposure levels, and burden of disease as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2021.
Carefully conducted risk factor meta-analyses can inform public policies on emerging or persisting health challenges, as well as identify notable areas of public health progress. To produce data for these analyses, the GBD estimates relative health risk by exposure, exposure to risk factors, and attributable disease burden for multiple risk factors.
The risk-outcome association was data-driven, and estimates specific to sex, age, location, and year were calculated at the regional, national, and global levels. For a given risk factor, relative risks of a specific outcome were estimated. Related StoriesUnsafe water, low birth weight, short gestation, handwashing, and sanitation were leading risk factors for individuals between zero and four and those between five and 14. For older cohorts, high body-mass index , FPG, SBP, and low-density lipoprotein cholesterol levels were key risk factors.
Conclusions The current study identified several risk factors for which sufficient actions have not been taken. Linking disease burden to risk factors is essential, as it can inform prioritization with limited resources.
