Study finds positive association between obesity and COVID-19 mortality across 142 countries Coronavirus Disease COVID Mortality Obesity SciReports TuftsUniversity TuftsMedSchool UTSA UWMadison
By Pooja Toshniwal PahariaApr 15 2023Reviewed by Benedette Cuffari, M.Sc. In a recent study published in the journal Scientific Reports, researchers determined the association between coronavirus disease 2019 -associated deaths and the percentage of obese adults across 142 nations.Background Related StoriesObese adult individuals are mainly concentrated in relatively high-income nations, whereas low-income nations comprise more significant proportions of lean individuals.
About the study In the present study, researchers explore obesity as a determinant of country-level variations in mortality rates of SARS-CoV-2 infections. Nations with per capita GNI of at least $12,536 constituted high-household income nations, whereas those with per capita GNI between $4,046 and $12,535 were considered upper-middle-household income nations. Nations with per capita GNI between $1,036 and $4,045 were considered lower-middle-household income nations, whereas nations with per capita GNI less than $1,035 were considered low-household income nations.
The predicted elasticity for COVID-19-related mortality regarding the percentage of obese adults was the greatest for high-income nations. On average, each percent point increment in the percentage of obese adults contributed to an additional 1.50% points to SARS-CoV-2 infection-associated mortality among individuals residing in wealthy nations.
