Introduction: Bone turnover leading to osteoporosis and poor quality of life is common during postmenopausal period. Study of bone turnover markers that contribute to non-invasive assessment of bone-metabolic disorders holds an important of research in low income country like Nepal. This study aimed to examine the correlates of bone turnover markers in post-menopausal women in tertiary care center of Nepal. Methods: A hospital-based cross-sectional study conducted during the period of November 2016 to December 2017 among 354 women. Blood samples for calcium, inorganic phosphorus, alkaline phosphatase and vitamin D were collected and analyzed using a validated and calibrated tools. Data were analyzed using Statistical Package for the Social Sciences software version 20. Results: Mean +/- Standard deviation of age of post-menopausal women was significantly higher compared to pre-menopausal women (post-menopausal women, (57.98 +/- 8.08) vs. pre-menopausal, (31.35 +/- 5.83), (P<0.001). Selected biochemical markers of bone-turnover such as alkaline phosphatase levels were significantly higher with year since menopause (P<0.001), whereas serum calcium, and vitamin D were decreasing with year since menopause among post-menopausal women. In addition, calcium and vitamin D were significantly negatively correlated with year since menopause (P<0.01) while body mass index, inorganic phosphorus and alkaline phosphatase were significantly positively correlated with year since menopause (P<0.01). Conclusions: Our study revealed that body mass index, inorganic phosphorus and alkaline phosphatase positively correlated with year since menopause while calcium and vitamin D were negatively correlated suggesting for a medical supervision of hormonal changes and periodic dosing of calcium and vitamin D among post-menopausal women to reduce the problem of bone health.
