Age-related reference value of serum osteoprotegerin in female as compared with other races / 中华内分泌代谢杂志

Serum osteoprotegerin (OPG) concentration was measured in 647 healthy female adults (aged 20-81 years), and was compared with that of other races. The serum OPG was positively correlated with age (r = 0.276, P <0.01). The geometric mean value of serum OPG in premenopausal women was significantly lower than those in perimenopansal and postmenopausal women. The serum OPG in middle-aged Chinese women was signifieandy higher than those in middle-aged Austrian and Icelandic, but this was quite contrary to the results obtained in old-aged women.
