Biochemical Markers of Bone Turnover during Pregnancy: A Longitudinal Study

Abstract: Markers of bone resorption were significantly increased during pregnancy. In contrast to bone resorption, markers of bone formation showed an increase as well as a decrease during pregnancy indicating a state of high bone turnover. This might coincide with the change in bone mineral density that was observed in some, but not all, studies using "dual-energy x-ray absorptiometry" (DXA) as well as "quantitative ultrasonometry" (QUS).

“…Our study results are consistent with limited, previously reported data, showing low P1CP and P1NP concentration in the first trimester 28,30 with the tendency to rise above normal in the late pregnancy 30,31 . Since type I collagen constitutes 90% of bone proteins, it may be considered as very valuable and precise marker of bone formation.…”

“…Pregnancy has been documented to be a state of marked enhancement of bone turnover [21], during which a significant loss in BMD could be clearly demonstrated by direct methods, including standard dual-energy X-ray absorptiometry (DXA) [11,22] and quantitative ultrasound [13-16]. This BMD loss is thought largely to be reversible in the long run [23,24].…”

“…Because BTMs have been shown to increase after a fracture and remain high for months afterward, 17,18 women with a history of fracture within the past 5 years were excluded from the study. Pregnancy also can affect BTM levels 19 ; therefore, women who were less than 1 year post-pregnancy were excluded from the study. Because concentrations of BTMs increase during puberty 20 and again during menopause, 21,22 premenopausal women aged 18 to 35 years were recruited.…”
