Abstract
This study investigated the association between hematologic inflammatory markers derived from complete blood counts and obesity. We undertook a cross-sectional study that included self-reported healthy subjects above the age of 18 years from the 2011-2016 National Health and Nutrition Examination Survey, a US population database. Study parameters included mean corpuscular volume, red cell distribution width, mean platelet volume, total platelet count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index. Body mass index was used as an index of obesity and was correlated with each hematologic inflammatory marker. Our analysis found a statistically significant association between each inflammatory parameter and higher body mass indices. We demonstrated an association between complete blood count-derived indices of inflammation and obesity, and these results provide the basis for future studies using complete blood count-derived variables and outcomes in patients with some chronic diseases.
