Plasma fibronectin in overweight men and women: correlation with serum triglyceride levels and serum cholinesterase activity.
When compared with 67 age- and sex-matched normal weight control subjects, the 71 overweight patients displayed obviously higher levels of plasma fibronectin. For a similar body mass index (BMI) the 16 overweight men younger than 45 years had a significantly (P < 0.01) higher plasma fibronectin level (455 +/- 99.3 mg/l; mean +/- SD) than the 16 age-matched overweight women (351 +/- 105 mg/l) while there was no significant difference between the 22 overweight men (446 +/- 89.2 mg/l) and the 17 overweight women (475 +/- 111 mg/l) older than 45 years. Particularly high plasma fibronectin levels were noted in the five women with upper body (android) obesity. Plasma fibronectin was positively correlated with BMI, serum triglyceride concentration, plasma fibrinogen and serum cholinesterase activity. It is considered that metabolic disturbances related to upper body obesity may lead to an enhanced hepatic secretion of VLDL and of several plasma proteins including fibronectin.
