Individual PAI-1 increase over nine years relates differently in men and women to changes in anthropometric, glycaemic, inflammatory and lipid markers.

• Background: Levels of plasminogen activator inhibitor-1 (PAI-1) is known to correlate to factors related to the metabolic syndrome. We have previously shown that PAI-1 antigen increased by 75% in men and 95% in women over nine years.Objective: The aim of this study was to explore relationships between intra-individual changes in PAI-1 and changes in anthropometric measurements, blood pressure, glycaemic, lipid and inflammatory markers, separately for men and women.Method: In northern Sweden, 125 men and 116 women were examined first in 1990 and re-examined in 1999 during the morning hours. Changes over time (Δ) were calculated as the value at 1999 minus the value at 1990.Results: In men, ΔPAI-1 was significantly correlated to ΔBMI (r =0.33), ΔCRP (r =0.25), Δtriglycerides (r =0.39), Δfasting plasma glucose (r =0.41) and Δ2-hour plasma glucose (r =0.29). In women, ΔPAI-1 was significantly correlated to ΔBMI (r =0.36), Δwaist circumference (r =0.38), Δhip circumference (r =0.27), ΔCRP (r =0.27) and Δtotal cholesterol (r =0.19). The multivariate linear regression analysis showed that ΔPAI-1 was significantly related to Δfasting plasma glucose and ΔCRP in men (R2 for the complete model was 0.31). In women, ΔPAI-1 was significantly related to Δwaist circumference (R2 for the complete model was 0.17).Conclusion: We expected that changes in anthropometric, glycaemic, inflammatory and lipid markers would explain a large part of the observed PAI-1 increase. However, the multivariate analysis explained only 20% of the variation in ΔPAI-1 in women and 30% in men. Interestingly, the patterns of components correlating with the changes in PAI-1 differed between sexes.
