['Serum sialic acid (TSA) has been shown to be a cardiovascular risk factor and an acute phase reactant, with elevated concentrations associated with increased cardiovascular mortality and to precede the onset of type 2 diabetes.', 'The purpose of this present study was to test the hypothesis that serum TSA may be related to serum leptin concentrations in healthy individuals.', 'Thirty Fijian individuals were studied (8 males and 22 females). They were urban Melanesians living in Raiwaga, a suburb of Suva in Fiji.', 'Serum TSA significantly correlated with subject body mass index (BMI, rho 0.39, P<0.05) and serum leptin concentration (rho 0.44, P<0.05). In stepwise multiple regression analysis serum TSA independently correlated with subject waist/hip ratio (r(2)=0.167, P<0.02) and diastolic blood pressure (r(2)=0.300, P<0.01) but not with age, BMI, serum insulin-like growth factor binding protein (IGFBP-1), fasting plasma glucose or systolic or diastolic blood pressure.'] Is serum sialic acid , a reputed cardiovascular risk factor , related to serum leptin concentrations in Fijians?
