Relationship between serum butyrylcholinesterase and the metabolic syndrome.

Objective: To identify independent predictors of serum butyrylcholinesterase (BuChE) activity and examine its relationship with the metabolic syndrome.

Design And Methods: Serum BuChE activity was measured and metabolic syndrome risk factors were assessed in 1097 healthy subjects recruited from the Newfoundland adult population.

Results: Serum BuChE activity was related to insulin homeostasis and correlated with fasting insulin levels (r = 0.
