Metabolic status and its association with bone activity in post-menopausal women

Introduction and objective: Changes in lipid metabolism, insulin sensitivity, and visceral adipose tissue increase cardio-metabolic risk. Recent evidence suggests that osteocalcin (OCN) may play a role in metabolism. However, little is known about the OCN in post-menopausal women. The aim of this study was to investigate the relationship between the concentration of OCN with obesity and metabolic syndrome (MS) in pre-and post-menopausal women. Methods: A cross-sectional study was conducted that included 261 participants who were reviewed clinically and underwent laboratory studies, including the determination of serum OCN and insulin by chemituminescence. Results: Of the participants, 128 were pre-menopausal, 133 post-menopausal, and 33% had MS. OCN concentration was higher in post-menopausal women than in pre-menopausal (7.7 +/- 5.7 vs. 5.3 + 2.6 ng/mL, P<.001). OCN levels in post-menopausal women with MS were greater than those without MS (8.4 +/- 5.1 vs 6.3 +/- 2.8 ng/mL, P.003). Conclusion: Oestrogen deficiency and insulin resistance are associated with increased OCN during the stage of post-menopausal stage. (C) 2017 Elsevier Espana, S.L.U. All rights reserved.
