Abstract

Abstract : Aims . To explore the relationships of procollagen type 1 N-terminal propeptide (P1NP) and β cross-linked C-telopeptide of type 1 collagen ( β -CTX) with bone mineral density (BMD) in postmenopausal women. Methods . All postmenopausal women were selected from a community-based case-control study. The anteroposterior L1-L4 and left proximal femur BMD were measured. P1NP and β -CTX were also collected and tested. The main correlation analysis was applied to explore the relationships of BMD, P1NP, and β -CTX. Results . The total 1055 postmenopausal women were enrolled. The BMD at all sites kept a decrease continually with age (P < 0.01 ). In addition, the level of β -CTX increased significantly from 45 to 50 years old and remained at a high level in the later stage, while the level of P1NP changed little or even decreased with age. Logistic regression model showed that β -CTX has better ability to predict BMD than P1NP, as demonstrated by an area under the curve (AUC) of 0.63. Conclusion . P1NP and β -CTX are important markers to monitor bone metabolism. This trial is registered with ChiCTR-SOC-17013090 . The date of registration is Oct. 23, 2017.
