Palestinian Arab ethnicity is associated with an adverse metabolic phenotype

Abstract Urban-dwelling Palestinians have been shown to have higher cardiovascular morbidity and mortality and prevalence of diabetes than urban Israelis. Inflammation is implicated in the etiology of these conditions. We hypothesized that increased inflammatory activation, manifested as increased GlycA, a novel biomarker of global inflammation, would be evident in Palestinians. We compared GlycA concentrations between Palestinians and Israelis and assessed the associations of GlycA with anthropometric, health behavioral and clinical variables in a sample of 1674 Palestinians and Israelis aged 25–74, residing in Jerusalem. The main outcome measure was GlycA concentration. GlycA was higher in Palestinians than Israelis ( p GlycA as well as adverse cardiovascular biomarkers are all higher in Palestinian Arabs than Israeli Jews, even in young healthy adults. This propensity to inflammation may be a driver of the higher risk of cardiovascular disease, insulin resistance and diabetes observed in this population.
