Introduction: Preliminary evidence indicates that the association of fibrinolytic potential, measured as clot lysis time (CLT), with body composition may differ from that of plasminogen activator inhibitor type–1 (PAI–1). We" therefore investigated the association between fibrinolytic markers (plasminogen activator inhibitor type–1 activity (PAI–1act) and CLT) and body composition using detailed body composition analyses. Materials and methods: Data from 1288 Africans were cross–sectionally analyzed. Body composition analysis "included BMI, waist circumference (WC); waist to height ratio (WHtR), skinfolds and body fat percentage" measured with air–displacement plethysmography and bioelectrical impedance analysis. "Results: PAI–1act and CLT were significantly higher in women than in men, despite adjustment for differences in" "body composition. PAI–1act and CLT showed similar linear positive relationships with body composition (BMI," "WC, WHtR, skinfolds) in men. In women CLT also showed a linear relationship with body composition, while" PAI–1act levels plateaued at higher BMI and did not differ across skinfold categories. PAI–1act showed stronger "correlations with body composition markers in men than it did in women, while no sex differences existed for" "CLT. PAI–1act associated more strongly with central obesity, while CLT associated with total body fat." "Conclusions: Observed differencesmay be related to differences in adipose tissue type, distribution and sequence" "of accumulation between sexes. PAI–1act is strongly influenced by accumulation of visceral adipose tissue, whereas" CLT is associatedwith obesity independent of type and sequence of body fat accumulation in this African adult study population.
