Plasma fibrinogen concentration in a Chinese population.
Plasma fibrinogen concentration has been shown to be a predictor of major cardiovascular events. Information on plasma fibrinogen amongst Chinese has been scanty. We examined the relationships between plasma fibrinogen concentration and cardiovascular risk factors in 988 chinese subjects who underwent 75 g oral glucose tolerance test for screening for glucose intolerance. The study involved a selected sample with subjects who had an history of gestational diabetes, delivery of big babies (birth weight > or = 4 kg), equivocal plasma glucose concentrations and subjects who were family members of diabetic patients. This was mainly a non-smoking (96.6%), non-drinking (98%) and non-exercising (99%) population of which 87% (n = 855) were female. Among the 988 subjects (age +/- S.D. 36.8 +/- 10.2, range 16-79 years), plasma fibrinogen concentration ranged from 1.40 to 9.90 g/l with a mean of 3.26 +/- 0.93 g/l. On stratification of the subjects into 4 quartiles based on plasma fibrinogen concentrations, we found that increased plasma fibrinogen was associated with older age, higher body mass index (BMI), systolic and diastolic blood pressure (BP), fasting and 2 h plasma glucose (PG), prevalence of diabetes, glycated haemoglobin (HbA1c) and triglyceride (TG) level. After adjustment for age and sex, increased plasma fibrinogen concentration remained associated with higher BMI, systolic BP, 2 h PG and TG level. On multivariate analysis using age, BMI, BP, TG, HbA1c and PG as independent variables, plasma fibrinogen was independently related to plasma TG concentration and HbA1c. With 1 S.D. change in TG concentration and HbA1c, there were 3.7 and 5.2% changes in plasma fibrinogen concentration respectively. These findings emphasize the close relationships between plasma fibrinogen and cardiovascular risk factors, in particular abnormal lipid and glucose metabolism.
