The mean of NMID osteocalcin = 21.45 SD = 11.18 95% CI = 20.12 to 22.79 ng/ml and beta crosslap = 0.445 ng/ml SD = 0.25 with 95% CI = 0.414 to 0.478 ng/ml in women who menopaused less than 10 years ago (n=237), these values were higher than in young adult females (n=63) and menstruating women (n=123) which was statistically signigficant (p=0.0001). The value of both bone markers in elderly women who had menopaused more than 10 years ago and were aged more than 60 years (n=94) showed a marked increase of NMID osteocalcin, 25.63 ng/ml SD = 14.22 ng/ml but the value of betacrosslap was below the young- menopausal women, 0.394 ng/ml SD = 0.241 ng/ml 95% CI = 0.344 to 0.444 ng/ml. Menopausal women are at a high risk of osteoporosis due to high bone turnover. In our study, the NMID osteocalcin had a high correlation with betacrosslap (r=0.789 p=0.0001) while both bone markers had a weak correlation with bone mass density of radius, lumbar spine and hip by DXA. (r=0.29 p=0.0001).Mahidol UniversityMedicineArticleSCOPUS
