Abstract/OtherAbstract:
We examined the relation of general and visceral adiposity to plasma hemostatic factors [fibrinogen, D-dimer, and plasminogen activator inhibitor 1 (PAI-1)] in obese boys and girls 7-11 y of age (n = 41). Boys had significantly greater fibrinogen and D-dimer concentrations than girls (P < 0.05). whereas blacks had significantly greater fibrinogen and D-dimer concentrations than whites (P < 0.05). Univariate analyses revealed that fibrinogen was positively associated with percentage body fat (%BF) (r = 0.42, P < 0.01), subcutaneous abdominal adipose tissue (SAAT) (r = 0.40, P < 0.01), total fat mass (r = 0.42, P < 0.01), and body mass index (r = 0.41, P < 0.01). PAI-1 was positively associated with visceral adipose tissue (VAT) (r = 0.49, P < 0.01), SAAT (r = 0.32, P < 0.05), fat-free mass (r = 0.50, P < 0.01), and insulin (r = 0.61, P < 0.001). D-Dimer was positively associated with %BF (r = 0.40, P < 0.01), SAAT (r = 0.37, P < 0.05), total fat mass (r = 0.40, P < 0.01), and body mass index (r = 0.43, P < 0.01). Multiple regression analysis revealed that for fibrinogen, sex and higher %BF explained significant independent portions of the variance. For PAI-1, higher amounts of VAT and fat-free mass were significant predictors. For D-dimer, ethnicity was a significant predictor. These results suggest that general adiposity and VAT may play a role in regulating plasma hemostatic factors in obese children. Even early in childhood, adiposity is associated with unfavorable concentrations of hemostatic factors that are in turn implicated in cardiovascular morbidity and mortality later in life.
